Who will publish first picture of mining rig on this GPU?  :P

What about these makes them attractive?

hi,

does someone have this card already in use? If so, how much kh/sec do you get out from it?

I'm just curious because I will get mine in the next days :)

Cheers

The cooling. But I would like to see the power consumption compared to the old R9 290.

hopefully better than 95c at full load.

I'm currently running one of these at 1030 core/1500 mem using sgminer and getting 920kh/s. It hovers around 70C at 70% fan speed. You could probably lower fan speed and let it go up to the 80s but like it to stay cooler and use the MSI Afterburner custom fan curve. I should be receiving my second one in a few days.

nice stats! may I ask for the sgminer config?

Why are there only 13 RAM pads? Shouldn't there be 16?

bump  ;)

Got 4 cards. The stats are just beautifull compared to other GPU's.

Im mining at 880/890 per card. In the conf i set the temp to 70 degrees and cgminer keeps the temp at 68 degrees with 60% fanspeed. its just marvelous!

CC: 1000Mhz
MC: 1350Mhz
PT: 20
I:20

what OS are you using? I really have troubles right now to get it work on windows 8. I can get max. 830 khash/sec and after 1-2 minutes displaydriver stopped working and it stopped mining. I really think that is a driver problem with windows 8, tried all catalyst versions from 13.10 - 13.12 and different motherboards with different chipset. and of course different cgminer versions.

would be really ncie if you could give me the following information:
Operatingsystem
Catalyst Version
cgminer version


thanks a lot!

I had the same problem... so i bought 3 times 4gb RAM and poof! problem solved.

CGminer 3.7.2
Windows 8.1 x64
Latest catalyst version wich is 13.12?

okay so you are now running with 12GB ram?

Anybody manage to get the power consumption for this GPU compare to 280x and 290x?

yes... i always red people saying this on several forums... never believed it and discarded it as rubbish... whos the fool now :)

On the other hand... im running 4 7970s on 2GB and never had problems with those!

I never got to the power consumption part of this card. im curious about this to! Because they do slurp allot :)

I installed 8GB from my gaming pc, now it works. think I must tune my cgminer config file a bit :) thanks for your help

okey forget it, 8GB is NOT enough for this card, ordered another 8GB so I will have 16GB in total. let's see how it wil work out tommorw

maximum Intensity I can set is 13. all above crashes cgminer (doesn't matter which version)

hum this is quite strange  ???
I have 8GB DDR3 and get a stable ~880kh/s with my 290 Tri-X using -I 20 -g 1 -v 2 -w 512 --thread-concurrency 32765 with clocks @ 1000/1350. I'm on Windows 7 x64 and I use cgminer 3.7.0 with catalyst 13.12.

I agree.. with 8Gb installed it could be.. it wont hurt... but it couldnt be!

will try your settings now. have you set clocks with msi afterburner or an equal program?

Yes I use afterburner and set powertune to 20, forgot to mention.

well it is working now. but after ~1 minute, display drive has been restored and stopped mining. man I'm sitting here sinc 48 hours and don't know what to do. tried windows 8, now I have windows 7 x64. have tried all catalyst from 13.10-13.12. and everytime the same.

thanks to your setting it is working now, but how I said, screen gets black for 1 sec and windows says it has restored the displaydriver.

btw did run furmark for about ~5 hours without problems.

These are the settings in my .bat that I'm using with one of these babys:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
-I 20 -g 1 -v 1 -w 256 --thread-concurrency 32765 --gpu-engine 1040 --gpu-memclock 1500 --gpu-fan 85 --temp-cutoff 75 --lookup-gap 2 --gpu-powertune 0


You may achieve better results by turning on powertune. I'll get a stable 973Kh/s @ --gpu-powertune 30. But its not worth it compared to the effort. Oh, and I'll have 8GB total under WIN 8.1 (yes, crappy OS, I know). The card runs @ 66°C 24/7. I'll have to  mention that it's a card with Hynix memory.

Awesome hashrate! I tried your settings but after a few seconds an error pops up saying that AMD display driver stopped responding and then the hashrate drops abruptly.
Are you using default voltage ? What's your cgminer version ?

Miner version is 3.7.2 and I didn't changed the voltage. Only thing I do/did is a) turn the jumper on the card to "uber-mode" and b) set screen resolution to 1024x768 and c) use a mono-color background for the desktop (I prefer blue). Maybe the last two settings aren't doing anything but I don't have any issues with drivers so far. I used a tool to erase any old driver software and then I installed 13.2.

loooool I haven't seen that switch on the card. that is a damn tiny switch.

edit: can you tell me: what is the switch position for uber mode? from the platine view: left or right?^^

Nice stats... what's the power consumption?

Well, I don't have to care about the consumption ;) But I will see next week on how much is needed.

@Tenchi Its the position towards the power connectors.

hm.. I switched it to the opposite and now it is working for around 10 minutes lol

And you hash rate is? Besides, "uber-mode" will only provide that the card is getting more power and is not shutting down early if it reaches 90°C. Since the Sapphire TRI-X is running very cool you may never need it anyways.

my hashrate is 877khash/sec with clocks @ 1000/1350 fanspeed 60% temp is 63°. and the whole system takes about 310 watt.

btw. how did you found out about that switch lol looked in the instruction manual and they don't mention it there. I really did not see that tiny little switch when I first looked at the card lol

As the world most famous (and only) Crypto General I used google. But I have to admit that it takes some time until you get that information. For some reason Sapphire missed out to publish an introduction/manual for that jumper.

hehe yeah. but I'm so happy right now that it is working :D

http://i42.tinypic.com/28cojfa.jpg

that's the switch possition which is working for me.

but can't get your clocks driver crashes after I start cgminer. but I'm happy with my results for now. worked 48 hours and then there is that little jumper  :P

edit: strange, after 50minutes cgminer stopped working.... will try new setting tomorrow

Its tomorrow - any progress?  ;D

not yet, will be out buying another 8GB ram (need it anyway) and test with more than 8GB ram.

does anybody know how I can see which bios on my card is enabled?

GPU-Z or HWiNFO.

hm.. gpu-z is installed, will look at it again. thanks

You should check if your card has Hynx memory. More overclock, such speed, wow.

Have you tried a couple of USB memory sticks with readyboost to see if that helps before buying some DDR3 RAM?

hm have now 4GB installed and I'm trying too tweak around with readyboost. so far I've tried a 8GB usb stick, but TC over 30k doesn't work, will now try a 16GB usb stick. oh and by the way
what bios are you guys using?

015.042.000.000.000000 (113-E285FOC-U003)
or
015.042.000.000.000000 (113-E285FOC-X003)

if all that tweaking doesn't help I will try with 16GB ram

cheers


edit: readyboost doesn't do anything, will now come with full power and add 16GB ram... let's see what it will do after that lol

btw: what motherboard do you guys use?
ah and all tri-x have hynix memory as far as I know (mine has hynix memory too)

ASRock 990FX Extreme9 - probably not worth the extra I spent on it for my 2 x R9 290 Tri-x's, but it seems pretty good.

Both cards are working and stable at just over 800kh/s, but letting them get used to mining for a couple of days before tweaking. The noise levels and cooler runs temps compared to the R9 290s are the biggest difference so far.

ok seems like problem is solved. needed to set clocks to 947/1250 because the tri-x uses the standard pcb, and somehow it doesn't like the oc. running stable 850khash/sec right now with my 4GB ram.

my setting:

 ;)

so out of the box settings:

GPU Core clock = 1,000
GPU Memory clock = 1,300

Don't work?

I'll try the TC 20481 tomorrow and see what happens.

no out of the box settings don't work with my system. I'll provide you now with all information about my system

Sweet! Thanks man. That config worked perfect for me and others were locking up my drivers. Much doge to you.

lol new problem: cgminer won't start. doesn't matter which settings or which cgminer version... think I will use that card for gaming rather than mining <.<'

You need to reinstall your drivers(again, I'm sure).

I am still wrestling with my 4x 290 Tri-x OCs.

have removed drivers, and installed new. nothing changes, cgminer won't start and gpu load is always 0%.

Do a full power drain; Shut down the system, unplug the PSU and hold the power button in to discharge the board. If it still won't start when you turn it back on it can be a few things.

Either you need to reinstall the drivers(look up how to fully remove the existing software before reinstalling).
You are lacking enough system RAM for the thread concurrency(try setting it to an intensity of 13 and TC of 8192 just to see if it starts. If it does start, you need more ram to run full power)
Or worst-case, you might have something corrupted in your BIOS or GPU firmware(unlikely, but possible).

hm.. tc isn't the problem I think because it worked perfectly with tc 20000. with 8-16GB ram I only gain about 20Khash/sec so I left the 4GB stick inside.
I think I've tried to start it with -I 13 or without any parameters, still doesn't start.

plugging out all power cables didn't change anything yesterday. but have done it now again.

does it help if I remove the battery from my motherboard and plug it in again?

EDIT:

tried everything, but cgminer won't start.

4GB ram is not enough for these cards. my rig has 16 and cards run at 1015/1500 tc 40200 - 910 Kh stable

tried it on an older pc with 6GB ram and got nowhere close to that - 900/1250 tc 22516 - 815 Kh

doesn't matter how many ram I put in. the only thing I can do with more than 8Gb is setting tc over 30000.
think I will switch to linux and see if I can get this card working there.

please need settings 5x sapphire cards r9 290 tri-x oc.
I have this pc.

2x ram 8g 1600mhz

I used all the settings that you have put all the time and stops.

Hey everyone,

I'm really struggling here.  I got my R9 290 Tri-x OC cards yesterday and started installing them in 4 different computers.  However, what I'm finding is that the cards have a consistent drop off and I mean in an extreme way and I have been unable to figure out why.

First some details.  I've moved the "little switch" to both positions on the cards with the same results.  I'm running BFGMiner 3.9 and I'm using a bat file with the following settings (I've used configs to), but keep in mind I've tried a hundred different settings with the same results.

-I 20 -g 1 -w 256 --lookup-gap 2 --gpu-memclock 1500 --gpu-engine 1000 --thread-concurrency 28456 --gpu-powertune 20 -S opencl:auto --auto-fan

The results are consistently repeatable.  The first 30 seconds to a minute is blazing fast with speeds greater than 1 mh/s, then there is a steady drop down to essentially nothing meaning lower than 300 kh/s.

For instance, I let two of the cards run in a computer over night and when I checked them this morning the speed was 140 kh/s per card.  On the one system where I just put one card it as at 280 kh/s in the morning.

I'm totally new to overclocking and the software to do it so bare with me here.  I installed TRIXX today to mess with the settings a bit to see if I can figure out what is going on but it seems the cards simply ignore the settings after a few seconds.  For instance, when I change the fan speed setting to fixed and set it high to see if the fan responds, it does for about 10 seconds and then it goes back to whatever it was doing before.  I do not know how to verify memory speed changes etc are actually taking effort.  I can't see any evidence that they are though.

EDIT: I struck out the part on the fan having a mind of it's own because I was actually running the miner in the background and forgot so BFGMiner was taking control of the fan again and slowing it down.  When I shutdown BFGMiner the fan stayed at the speed I set.

It seems the cards are marching to their own drummer so-to-speak and I haven't figured out what is going on with them yet.  I've tried four different cards so far though and they are all acting the same way in two different computers.

One of the computers have 8 gig of RAM the other 16 gig of RAM.  EDIT:  Each computer is running Windows 7 x64.

I'm puzzled though.  Has anyone else run into something like this?

try this with msi afterburner latest beta
http://www.overclock.net/t/1437876/290-and-290x-litecoin-mining-performance/1650#post_21648437

maybe it does help you.

Thanks Tenchi.  I've got that thread bookmarked but that is a lot of reading to get through.  170+ pages but I'm digging there as well.  :)

not the whole thread just the post I have linked ^^

I started reading where you posted.  Thanks again!  I'll report anything I find out.  I do think the part about setting a different worker for each card is what I've run into but the overall hash rate even with one card is far too low.  I also need to back up in the thread to find out how to see what type of memory my cards have.  I got 14 of them from the same vendor at the same time but until I get this worked out I've only messed with 5 cards.

I uninstalled MSI Afterburner when I installed TRIXX because I thought at the time that MSI Afterburner wasn't recognizing the cards. 

I also needed to order DVI-D to VGA adapters.  It never occurred to me that they wouldn't be included in the package.

Had the same problem as you initially.

My rig has 5 cards, 1 x Gigabyte 7950, 2 x Gigabyte 290 (reference), 2 x Sapphire 290 (Tri-X)

The tri-x would continue to driver crash regardless of which bios switch I had on, or whatever clocks I used (even 947/1250) would crash.

I flashed the bios on the tri-x to the Gigabyte 290 (reference) bios and now its working flawlessly.
Heres the link http://www.techpowerup.com/vgabios/147971/gigabyte-r9290-4096-130930.html (http://www.techpowerup.com/vgabios/147971/gigabyte-r9290-4096-130930.html)

Left clocks at 947/1250, also undervolted by 31mV and am getting 850kh/s stable.

My system is using 4gb ram only.

Make sure you guys are using sgminer (3.7.2 cgminer fork) which includes a ton of code fixes for the R9 290s. This fixed any issues I had. It's bundled with the new BAMT 1.3.

sgminer was recommended to me last night in a thread Tenchi referred me as well.  I absolutely could not get decent performance with BFGMiner with the R9 290X TRI-X's but with SGMiner it was smooth and no issues with the miner part.

Now I'm struggling to get Windows 7 64 bit to recognize more than two of the GPU's at once but that is another issue altogether.   :)

guys can you tell me what the switch on the card is for on the r9 290 tri x oc?
Is this a second bios or what?

Because 290 wont have uber mode correct?

where can I download newest sgminer?

I believe the switch is for two different sets of BIOS.

Regarding getting sgminer.  Here is the link to the reddit about it.

http://www.reddit.com/r/litecoinmining/comments/1va8g2/ann_sgminer_400_release/

And here is a forum link talking about it.

https://bitcointalk.org/index.php?topic=419428.0

Hii im using windows 7 64bit cgminer 3.7.2

if someone need it, this is my setting, avg 980 khash/s

cgminer --scrypt -o stratum+tcp://THEPOOLADRESS:PORT -O YOURUSERAME:YOURPASSWORD -g 1 -w 512 --lookup-gap 2 --thread-concurrency 24550 -I 20 --gpu-engine 1022 --gpu-memclock 1500 --gpu-powertune 20

These settings worked brillianty for me. Thanks!

My fans still run at a very high intensity even after shutting down sgminer; with the above configuration. Anyone know what I can do to resolve this? Thanks!

Hi!

Im pretty novice about Gpus and found this thread when i was googling, so was wondering if any of you more advanced gpu guys know anything about my problem.

i bought two R9 290 Tri-X OC and they worked fine first ours. But now i cant change the fan anymore on one of them?
 Fans spin but will not increase how hot it gets .. Is there a reset switch etc. .. or what can I do?

Tested gpu in another computer with the same results, running at standard speed despite 90 degrees in the Valley Bench :(

Would be very grateful for some advice so i can start to play with the mining settings.

My cards are running 875 with a power consumption of 315 watts.

Ratio 2.77.

Cany anyone beat this?


It would be nice if anyone could include the power consumption as well.
I'm not intrested in 950 khs with a power consumption of 450.

Thanks
Merred

Power consumption really doesn't matter at current mining profitability, unless you are paying a lot for power.  Tuning power consumption might be relevant later to extend the life of equipment, but right now you should be optimizing output not power consumption.  My rigs pay off their monthly power consumption in 1-2 days of mining, bringing that down slightly and losing a big chunk of income makes no sense.

I have 3x R9 290 Tri-X OC running at over 945KH/s, and 1x running at 930KH/s.  (The 930KH/s won't take the memory overclock, so it runs at 1250).  Max temp is 75 degrees at 80% fan.

--

Regarding RAM... WTF are you guys talking about?  I have my 4 cards running with 4GB of whatever-was-cheapest DDR3 RAM.  If you need more RAM for mining, you're doing something wrong.

what are your settings phzi? i cant pull much more than 912 on both of mine.

 
Right now I have stabilized to:

This yields consistently over 945KH/s (945-948) and over 900KH/s (901-905).  Reject rates are down around 0.3% (almost all my rejects are because of vardiff causing Share above target), and WU is consistent with hashrate.

The 1250/1020 card faults after about an hour if I push it beyond 1040, so I pulled it back to 1020 as seems to be stable so far.

Instant crash  :'(

looks like not all Sapphire R9 290 Tri-x OC are good for mining.

The fun part is, I can play games like Battlefield 4, Tomb Raider etc. etc.  24/7. No problems here. From now on this is my new gaming card, wanted a new card for gaming anyway  :D

Btw.: Look at GPU-Z, the memclock of my card won't go over 150MHz in cgminer. As soon as I start playing a game it goes up to 1300 and stays there until I quit.

started mining Ultracoin with Scryp-Jane algo.... everything works perfectly here! so it seems some cards have a problem with the scrypt algo lol

I have received 2x R9 290 Sapphire Tri-x (hynix). They are both totally different, I disconnected all of the cards and were running just them to fine tune. In gpu-z they have 84% and 76% asic quality, funny is that the lower one behavies better. I’m minning vertcoin which is using different scrypt but on reference cards usually clocks didn’t change for me much. What I find is that probably both cards can’t run on 1500 memory clock.
First card
1025-1040/1475 seems to be ok.
Second cards
Anything higher than 985-990/1450 and I get artifacts/HW errors. With 980/1500 I got HW right away, with 980/1475 left over night, I wake up and found 7HW..I left it now with 980/1450 and will see afternoon if any HW comes..
Both cards doesn’t tolerate undervolting (even -6mv gives artifacts and soon after freeze).
They are hashing nice, around 470 and 455 on Vertcoin which is 50% of scrypt performance.
I don’t understand why they can’t handle 1500Mhz, and one even 1000Mhz on engine if they are reference. My 3 other reference cards go no problem 1020/1500 (elpidia) with -19mv..And those 2 are hynix which supposed to be better.
p.s. Even if I’m able to run stable with 1025/1475 on 1st and 980/1450 on another one, as soon as I stop minning I got computer freeze few seconds/minutes later , which is not the case on reference cards and it indicates that even these clocks are to much for them..What I like in these cards is extreme LACK of noise :) they run super quiet, around 70 degrees with 60% fan. WOW!!

On the R9 290, usually memclocks between 1250 and 1499 will decrease performance.  If you can't hit 1499/1500 memclock, then use 1250.

not on hynix cards mate..r9 290 with elpidia and with hynix meories are 2 completly different cards and require complety different tunning..what You said is completly right for elpidia models. If I go 1499 or 1501 my hashrate drops a lot, but not on hynix one's.

I am using them, and client from my first groupbuy is using them aswell :) I am getting 3100Kh/s 1230W, no undervolting. 4 cards

I still have 11 cards left for sale in my second groupbuy, feel free to join! :)

Here is his settings and power usage:
https://bitcointalk.org/index.php?topic=438191.msg4804508#msg4804508


Oh sorry, its 290... I was talking about 280x.. I didn't even knew there is tri-c for 290..

Use MSI afterburner then click reset.

I have both elpidia and hynix cards...

I'm currently using 947/1250 for a R9 290 Tri-x for 825 KHash.

Kind of disappointed, I could have got a 280X almost at this hash rate.

Although it's been around 25 degrees in Auckland (NZ) lately, even wiath fan at 75% my GPU temp gets to around 82.

Why did you down clocked it?

some Sapphire R9 290 Tri-X won't run stable if you run it with 1000/1300 when using SCRYPT algorithm. Seems like a fault in some batches.

My whole system eats 390-400 watts on the wall using a watt meter.

i5 4670k
CM Hyper 212x
GA Z87x UD3h
2 x 4gb DDR3 RAM
One HDD
seasonic bronze m12ii 750 watts
r9 290 tri x
5 fans with led

Downclock mem from 1350 to 1250, you will see better performance. I have yet to see any R9 290 that hash scrypt well at anything other then 1250 or 1499/1500 mem clock, and I personally run 24 of these cards, and have tuned many more for others.

Basically, R9 290s either 'take the mem overclock' aka handle 1499 mem, or they don't. After you determine that, find your max stable engine by increasing to 1020, and then decreasing or increasing in increments of 10. Only decide an engine clock is stable after 24hr.

I will try that. Mine right now is 1000 / 1420. 883 khs at intensity 20.

Good rate but i have seen better ones try to play with voltage...

I tried moving my mem clocks up to 1500 but ended up putting back to 1350. I read on LTCtalk that 1250 is better. Will be trying when I have a chance. Right now I get 880 with 1000/1350. I want to see 900-950 stable.

Anyone tried a different BIOS?

I flashed a few, then when I reboot into windows CGMiner swaps my cards around, and detects the R9 290 in slot 1 and my 7870 in slot 0...

Flash back original BIOS and it goes back to normal.

Any ideas?

Haha that's what I'm doing. I thought therw was a way for it to auto-reset things as I exit the miner? No? :P

As long as you quit with Q rather then by pushing the X on the titlebar, the stock fan speeds should be restored.

Excellent! Thanks!!

Hello,

I tried everything, but it seems that my two Sapphire Tri-X R9 290 couldn't be underclocked below the default values - GPU Core - 1000 MHz, Memory - 1300 Mhz - I set for example GPU core at 947 and Memory at 1250, but when I look in GPU-Z (latest version) I see that the default values are shown and the change haven't been applied. I tried setting this in CGMiner 3.7.2, SGMiner and with Afterburner. I can set a higher clocks (like 1080/1500, or 1060/1499), but then the driver keeps failing and only the second GPU is actually working (at around 950 MH/s) and the first one isn't mining at all.

For the moment they are both stable in the same time only at default clocks (1000/1300) where I get 882KH/s per GPU.
I've tried to tick the jumpers on the cards, but the system haven't even start, so I've reverted back the change.

I am using 8 GB ram, Win7x64, Catalyst v13.12. My SGMiner config is the following:

"intensity" : "21,21",
"gpu-threads" : "1",
"vectors" : "1,1",
"worksize" : "512,512",
"lookup-gap" : "2",

Why are you using such a low intensity? 820KH/s is pretty bad for these cards. They should happily run 900 with very minimal tuning.

Temperature. Too hot where I am at the moment to go any higher.

You find intensity increases temps?  I haven't observed that. The number of threads you launch shouldn't affect power consumption (and therefore heat output) unless you are talking about very low intensity. Only clocks and voltages mattered in any of my testing.

Do any of you know how to get the r9 290 to work with linux?  I've been having issues with opencl support, ect.

The same as every other ATI card, but make sure you use thr 13.12 drivers (earlier drivers and 14 beta won't work with the hawaii cards).

Ah, thanks.  I've been trying to use the 14 beta...

How are the fan noise compared to stock r9 290x?

I have this exact card, and the 13.10 drivers didn't even recognize it. The 13.12 work find though

Endlessly quieter, even at 100% it is reasonable to sit right next to.

I run 2 of them on SMOS 1.3 with Catalyst 13.12 and cgminer kalroth

One is running smoothly at 925 khash / 70 C at 1065/1250 with TC 30719

Two blacks out at 890 khash at 1010/1250 and is 6-8 C warmer, already when idle.
I also have to lower TC to 25559, or it crashes after some hours.

I would undervolt the second one, but how to?

Hi I have problem with these cards, when i put on mobo direct whitout risers cards working stable for weeks but when I connect any riser (16x16, 1x16, and new usb riser) after 2-3 minutes computer switching off and I can't switch it on after unplug power from the wall and wait 1-2 min then mobo start normal.I try on windows, linux , with diffrent drivers but I think it's not problem with drivers. can anyone help me with this?

Sounds like a power issue.  How many cards, what motherboard, and what PSU?

Guys help, one 290x Tri-X cant work "Scrypt" all time driver down ((( only "kessak" work !.. all games work normal.

Help plz

should we install ADL_SDK when using 13.12 @win 7 64 bit?

i use this combination

also i would like to know i have i4770k but i when i enabled  igpu i cant use my r290s.Why is that?

i too cant use integrated and 290 (((

You should NEVER install ADL_SDK unless you are compiling your own mining software.  It is for development only, and serves no purpose otherwise.

Ik88: you try downclocking the memory?  kessak doesn't use much memory, whereas scrypt is highly dependent on memory bandwidth.

Yep i use 1200-1250 Mhz memory and all time crash driver ((( games not crash (((

I made some headway last weekend.  I gave up on Linux after being unsuccessful with BAMT and SMOS.  I installed Windows 8.1 and was mining in 30 minutes.  Amazon still hasn't shipped my 1300W PSU so I'm currently only running 5 GPUs with an 850W and 1050W.  Out of the box they were all running around 860 kh/s.  I've spent the last couple evenings tuning and things are looking promising. 
Things I learned along the way that seem to have helped:
1. Use Catalyst 13.12.  The 14.2 beta drivers were very unstable.
2. Don't bother with Trixx.  Install MSI Afterburner and use the settings shown on this post (link). (http://www.overclock.net/t/1437876/290-and-290x-litecoin-mining-performance/1650#post_21648437)
3.  I don't know if this helped or not, but I'm currently running with the bios switch toggled up (toward the end with DVI ports)

I think I can push them a little harder, but am currently limited by power.  The 1050W is essentially maxed out, so I have the engines turned down on some.  Here is my screen after 6 hours of mining.  I would have had a longer run time, except the power blinked last night and for some reason it didn't autostart like it should have.

Here are my current settings.

@dloganbill:
- try running everything at the same thread concurrency.
- switch to xintensity instead of intensity to gain a few more KH/s (try xintensity 300 or 400 - adjust higher for a few more kh but potentially higher rejects depending on what pool you are mining with)
- with wafflepool, you can tune (x)intensity pretty high, because they count what would normally be 'stale' shares as valid. e.g. a share that is 1 block outdated is still valid on WP - 1100 seems like a good balance on WP.
- try worksize 256.  I stopped using 512 entirely.
- try gpu-memclock at 1499 instead of 1500 for a few KH benefit on stock
- flash to STILT's BIOS and drop gpu-memclock to 1375 or 1400 and gain a few KH/s in the process
- I always say not to use auto-fan.  Try to find a stable fan % that will keep your cards cool and noise reasonable, and fix it.
- expiry should probably be at least 2 - you will find a lot of shares being considered stale when they aren't if you use 1.  I use 4/8 for scan-time and expiry on wafflepool.
- BAMT/SMOS kinda suck.  Try rolling your own linux install if you want stable linux.  But if you have the cards running stable on Windows, keep with it.  I have never had much luck getting cards/driver stable under windows over a long period.

Thanks for the pointers phzi.  I'll try them out tonight.

One more thing, can you point me in the right direction on the Stilt bios I need? I'm a little confused because I thought I remembered reading that his BIOS was only for reference cards.

For reference-design motherboards only.  The Tri-X have a reference mobo.

dloganbill: did you use 13.12 Catalyst and modified inf files in win 8.1.

I don't know what a modified inf file is so I guess not.   ??? This is my first build, so please don't laugh if that was a stupid answer.

Just so you guys are aware, a lot of these cards seem to be shipping with low amounts of thermal compound on the chip. Out of 13 I've so far had to replace the compound on 2. So if you see a card running with really high temps compared to the rest with 100% fan and lower than normal hashrates, then I'd check it. Perhaps the thermal compound is just burning out from heavy use but I constantly monitor them and one was brand new out the package. Also noticed a high amount of dust trapped in the heatsink, so be sure to blow that out if you're in a dusty area.

The thermal paste on most cards is worth replacing - usually it's too much, not too little, however.

Thanks will take a look at the weekend, I have 3 of these cards they all have different Bios & they all have very different temps

900 with 1025/1440

any setting with 1250 mem don't give me more than 870(tried everything)

i can reach 940-950, with 1500 mem and 1040 core, but it isn't very stable

mmh 1045/1480  920kh/s, seems stable..

Try STILT's BIOS.  It makes the mid-range memclocks (between 1375-1450) much higher performing.

hello
I have r9 290 tri x OC
this card is crazy working almost double better than 280x but sometimes drivers crashed after 10 minutes sometimes after 20 hours
I have setup multipool wafflepool and runing from 280 to 910 usualy work on 888kh/s with around 70 degrees
win 7 4G ram

cgminer bat file

--thread-concurrency 20481 -I 19 -g 1 -w 256 --gpu-fan 50 --temp-overheat 85 --lookup-gap 2 --gpu-engine 1000 --gpu-memclock 1350

what you suggest ?

Drop memclock to 1250, retest for stability. If that fails, drop engine clock by 10. Repeat until stable. (Change setting, run until crash, repeat). Some of the tri-x cards only run stable at lower clocks.

Also, Linux drivers tend to have better stability then Windows for the Hawaii chipsets, from my experience.

No point using i 19 with wafflepool, because they only count 2-blocks-late shares as stale.  Better off at I 20 or above, or using xintensity at up to 1100 (best value I have found for WafflePool for WU productivity).

I have instaled trixx and when I set to 1250 memory  works on 1300
lowest for cpu is 1000

Stop using trixx. It really sucks.  cgminer/sgminer can control your gpu clocks just fine.

where to download it?

i have the 43 bios on my 290, i can't do it then..

Only some cards with the newer BIOS cannot be downgraded.  Some still can.  Try and find out, or use a meminfo utility to find out if your RAM nodules are compatible with the old BIOS.

I'm in the same boat with 015.043 on my cards.  No other BIOS files (including STILT's) are compatible with these cards. :(  Best I'm getting is like 820KH or so, bleh...
