Sapphire Radeon R9 290 Tri-X OC

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.

And here is a forum link talking about it.

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

[ToScA-]

this is my config:

Code:

"api-allow" : "W:127.0.0.1",
"api-listen" : true,
"api-port" : "4028",
"expiry" : "120",
"failover-only" : true,
"kernel-path" : "/usr/local/bin",
"log" : "5",
"queue" : "1",
"scan-time" : "60",
"scrypt" : true,
"auto-fan" : true,
"gpu-threads" : "1",
"gpu-engine" : "1000",
"gpu-fan" : "50-90",
"gpu-memclock" : "1350",
"gpu-powertune" : "20",
"gpu-reorder" : true,
"intensity" : "20",
"temp-target" : "70",
"temp-overheat" : "95",
"temp-cutoff" : "99",
"temp-hysteresis" : "3",
"vectors" : "2",
"worksize" : "512",
"lookup-gap" : "2",
"thread-concurrency" : "32765"

this is a steady 880 per card.. (got 3 connected now)

Motherboard: MSI Z87 G45
Memory: 12GB
OS: Windows 8.1

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

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:

Code:

"gpu-threads" : "1",
"xintensity" : "1100",
"thread-concurrency" : "25601",
"worksize" : "512",
"lookup-gap" : "2",

"gpu-fan" : "80",

"gpu-powertune" : "20",
"gpu-memclock" : "1499,1499,1499,1250",
"gpu-engine" : "1060,1060,1060,1020"

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 

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.

[Tenchi]

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

[mattbigblue]

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.

[mrugala]

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

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!

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.
