Good settings for R9 290

[MIN3R]

I have 6x Sapphire R9 290 reference design using kalroth 3.7.2 with xintensity... I run all but 2 of them at 1050/1500 clocks, those 2 can only run engine up to ~1025 with good stability (and they get ~915+Kh/s), a few could actually run up to 1070 (which gets ~950Kh/s) engine clocks. Anyway with 1050/1500 clocks, xintensity 500, tc 20478 I'm getting 930+Kh/s 

Now some detail on where I came up with my settings:

I use "xintensity" 500 because it's just slightly higher than "intensity" 20, which I can explain:

• The raw value of "intensity" is 2 to the power of "intensity", so "intensity" 20 (which I previously ran) is a raw intensity of 1048576.
• "xintensity" is computed as a multiple of the number of shaders (2560 for my r9 290). So my "xintensity" 500 is raw intensity of 1280000.

Intensity explanation from the dev who wrote it if you'd like to know: https://bitcointalk.org/index.php?topic=87022.msg956792#msg956792

For thread concurrency I use 20478... I came up with this value by 2560 (# of my shaders) times 8 which equal 20480, minus 2. I'm not sure why the minus 2 seems to be the good spot, but if I use exactly tc:20480 it produces less hash rate. I tried multiples all the way up to 13 (tc: 33278) but anything over 20478 didn't seem to drastically help, so I just use 2 under the lowest multiple (8 in my case) of shaders that produced a good hash rate.

For my temps I set the target at 85, I have these 2 rigs (3 cards/machine) running in a spare bedroom (with a small fan blowing out of the room) and the temp in the room is usually 80*F due to the miners running but I do have a 20" box fan blowing directly on them. Needless to say the card's fans are usually at 85%+ due to the high ambient heat, I probably need to move them out to the garage to have more space to dissipate the heat generated.

If any of this helps anyone, any donations are greatly appreciated

Couple shots of my rig, I'm actually up to 9 GPU's in this frame now instead of the 6 shown... Sorry they're blurry, got bad lighting in the room

And your power consumption and WU are... ?

[tyrone3]

Could you post your .bat file? that would help a lot.
and are you using windows or what? what are your hardware settings?
but very helpful allready, thx

[leannemckim46]

Nice gpu position..

[MIN3R]

And your power consumption and WU are... ?

Power consumption ~2400-2500W (2 PCs') at the wall including CPU & other mobo accessories (not including monitor). I'm really not too concerned with power consumption, I'm "banking" on the coin increasing in value making money over fretting over 10-20W of power savings because electricity is cheap IMO to the potential gains. For January my electricity "only" went up ~$160, I say only because it was dwarfed by the almost 2K worth of coin I mined

I'm mining mostly on middlecoin, so I think the reject rate is high(er) than "normal" due to that... But I haven't mined just LTC in so long there's no telling, lol. I do know when I started doing multi-coin pools the reject rate went up without changing a single setting.

This is showing the additional 2 XFX R9 270's mining, the power for those is not included in the above wattage, just the 6 R9 290's. It shows as only running for 15 hours due to an internet outage last night, with these settings and no outage it's ran for over 3 days straight without issue

Thanks, I figured heat rises naturally so why not let it plus help it out a little bit more with a 20" fan! I'm building another 3 of these rigs this week (2 mobo's per rig, 5 GPU each), gonna change it up a little bit but same basic idea

You have 10% (!) reject rate, your cards run over 80c and your WU averages at 833..
If this 2400w-2500w is true.. than wooha man, each of your GPU is eating 400w-416w, that's crazy.
I got 3x r9 290 and I'm getting 800wu, with 3% reject rate (on middlecoin) and my cards only eating 250w~ each (and they run at 74c-78c)...

[RandomUser456]

I found that when I switched to EU.middlecoin instead of the default middlecoin address my rejections dropped significantly, might be worth trying a local middle coin server to reduce your rejections.

Yea the reject rate is high I agree, but I think that is somewhat due to middlecoin, and yea probably somewhat due to my overclocking.  

Just double checked my wattage (at the wall with a Belkin Conserve Insight), at idle it pulls around 100W, after ~15 minutes of mining it was pulling ~1170W. So it's not quite as high as I previously stated, but still a lot higher than yours @ 1070/3 which is 358W. That's on a 1200W gold rated PSU (http://www.coolermaster.com/powersupply/silent-pro-gold/silent-pro-gold-1200w/), which states a maximum of 90% efficiency, but that's 90% efficiency at 50% load...lol. So lets say it's at 87% efficiency (but realistically probably less) since it's > 90% load, which would estimate that each GPU actually using ~311W

With all that being said, in GPU-Z sensors section it states the 290 cards are only using 245W each, so basically in line with what you're saying


I do have my target temp set at 85*C, from the factory the cards are designed to run at up to 95*C so I figured 10*C under that should be plenty safe... And allows more power that would be going to the fans to keep it under 80*C to go to keeping the clocks from throttling and/or more stable at higher frequencies... At least that's my thoughts on it

I found that when I switched to EU.middlecoin instead of the default middlecoin address my rejections dropped significantly, might be worth trying a local middle coin server to reduce your rejections.

I actually used to use the eu server myself even though I'm in the US because I got lower reject rates. Only recently switched back to the main server b/c it was stated on twitter that: "All pool servers are out of beta. http://Middlecoin.com  now points to your closest server." I just switched back to the eu server to see if it's still better

I figured I would just post my .conf since it gives me pretty solid results.  I have one card that runs a little hotter than the rest so I was able to clock it up to 1050 the rest don't like to go above 1000. I achieve 915kh/s on the hotter card and 875kh/s from both of the others and over 800-830wu for each. Though a smaller pool I'd recommend http://wafflepool.com/ if anyone is looking for a solid most profitable coin pool. I get 1-2% reject rate and my payouts average .01btc per 1mh/s. One cool feature I like is being able to change the worker diff by password. I hope this helps someone!

[Amph]

what is your voltage? you can probably undevolt it, to gain some in consumption

[IMJim]

Hey all,

Can anyone offer me some advice with optimizing my config to get most out of my card:-)  Am very new to all this and have gotten a bit frustrated trying to figure this out on my own.........what a fun world this though.......5 days in and I am HOOKED!

I just bought and installed a Sapphire R9 290X 4GB GDDR5 DUAL DVI-D/HDMI/DP TRI-X OC Version PCI-Express Graphics Card 11226-00-40G.  It is my understanding from reading through some of this thread that I should be able to achieve around 950k/s, but have only been able to get her up to around 750.

Here is my current cgminer.bat file contents (I tried last night putting parameters in the conf file but kept getting erros and cgminer would not open)..........

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe -I 20 --worksize 256 --thread-concurrency 33792 --gpu-memclock 1350 --gpu-engine 1025 --gpu-powertune 20


Also........what parameters would I want to adjust down when I needed to work on the computer?  My current settings as pasted above will not allow for other things and work to be done.  This first card is installed on a spare machine so it will run full throttle all the time once I manage to get her floored.  I have another identical card I will be installing today in my main work machine so will need to tweak the config on it when I work.

Much appreciate any advice I can get!

When using the computer at the same time you'll want to lower the intesity. so -I 16 should allow you to use the computer without it locking up, etc. Also, does pushing the memory to 1500 change the results...Also, sidenote. I had to upgrage from 4GB-8GB system memory in order to push my cards further.

[IMJim]

I'll try the 1500 with the memory, not being too familiar with this stuff that was a number I was bit hesitant to play with.  Def not a ram issue though, this system is running an 8 core CPU with 16 gigs of ram....hardly anything on it but the operating system, drivers and a few needed programs.

[IMJim]

ahhhhhhhh THANK YOU so much!!  Changed the mem to 1500 and BOOM.....she almost wants to hit 1mh/s and stay there:-)  Seems to have leveled off at 930-950kh/s.  Crazy how one little tweak is all she takes.  I was messing around with this config file for a couple hours last night....had gotten up to about 850kh/s but was giving me problems so settled on the 750 and called it a night.  I guess I should have not been shy asked sooner!

Feels like I am getting my card's potential now......now I just need more cards:-)

Thanks again so much!feels like I am getting my card's potential now!!

You're welcome I'm glad I could help! If you want to put the card at the limit I believe you can go to 1550 for ram, but that's right on the edge and my cards don't like to go that far, just figured I'd let you know.

I'm actually overvolting to maintain stability, but only +31mV per card... With my clocks/intensity like I have it, it's just low enough that it doesn't crash the system while mining. If I happen to lose internet connection the PC will generally lock up due to instability. I've never actually tried undervolting though so I might, it could just be unstable clock settings and not much to do with my voltage settings
