tc 32765 / mem 1250 / eng 947 powertune 30 should get around 910khs

tc 32765 / mem 1500 / eng 1020 powertune 30 should get around 980khs

for me atleast

heres some settings
https://docs.google.com/spreadsheet/ccc?key=0ApyK2Y6kDbKidGFrWjh1WkNIeW5WSF96YS1TVW1MZWc&usp=sharing#gid=0

I have 8 GB RAM

T
Does anyone have Sapphire R9 290X 4G DDR5 (SKU: 21226-00-40G)?

I tried everything but TC can't be higher than 25000, best performance at 22528, that is around 840khps.

Other settings standard:

"intensity" : "20",
"worksize" : "256",
"lookup-gap" : "2",
"shaders" : "2816",
"thread-concurrency" : "22528",
"gpu-engine" : "900",
"gpu-fan" : "90",
"gpu-memclock" : "1550",
"gpu-powertune" : " 0",
"temp-cutoff" : "90",
"temp-overheat" : "85",
"temp-target" : "80",

"api-port" : "4028",
"expiry" : "120",
"failover-only" : true,
"gpu-threads" : "1",
"no-pool-disable" : true,

"log" : "5",
"queue" : "1",
"scan-time" : "60",
"temp-hysteresis" : "3",
"scrypt" : true,
"kernel" : "scrypt",
"kernel-path" : "/usr/local/bin"

Any idea why cards go in failure when increasing TC above 25k? Do you think I could get more than 840 khps from those cards?

how much ram do you have 4 or 8G

I think the RAM speed is too high, especially without the powertune. Try at 1400MHz and see if that works, 290x should be able to handle  --thread-concurrency 32765 (27400 works good on 290) rather well and "worksize" : "512", GPU engine will be fine at 940Mhz, but hot. Judging by the temp target, you aren't using a stock card, no need to have fan running at 90%. 45-75% will do.

"auto-fan" : true,
"gpu-fan" : "45-75",

tnx...I'll try your suggestions and let you know if it let me increase TC....should I also set the powertune to 20 or something like that?

OK, I'll try step by step, as far as I come home from my job.....

But do you thing all Sapphire R9 290X cards could run with such progressive settings, they aren't all the same, are they?

well they can have either hynix or elpida memory
think that is the only difference on reference cooler cards
http://www.overclock.net/t/1457836/determine-hynix-elpida-memory-on-290x-cards-based-on-product-number-before-buying-them-confirmation-needed-please-help-if-you-have-a-290x

btw settings i gave needs high fanspeed atleast for me ~75-88% to run 80-87c
for me it is to noisy cos my rig is right next to me and we have 2 children
so i run tc 32765 / mem1250 / eng 870 / powertune 30 / fan 60% to get 835kh/s @ 87c around 225-250w power usage
whenever we are home and tune it to "jet engine" when we are not home

Hey all. I haven't really played around with a .conf file and usually just set up different .bat files for each coin that I mine. I don't have a large setup but then again, I mine solely as a hobby. I'm running 3 GPUs, 8GB RAM, 2 PSUs (Totaling 1400w) in a milkcrate rig. For the most part my temps range anywhere from 72-78C with a Honeywell fan ($14 on Amazon) directed just below the GPUs. I've tried placing and directing the fan at different areas of the rig, but I seem to get the best results directed just below the GPUs. Without the fan, my rig was running 85-88C. Watercooling is not an option for me.

I'm using Windows 7 64bit and haven't used Ubuntu or any other type of miner. I just use CGMiner in conjunction with CGWatcher. I also run the "--auto-fan" command. These are my basic settings for my Sapphire Tri-X R9 290x (Stock bios & voltage settings). If you have any questions, don't hesitate to ask. I don't claim to have the answers to everything on every setup...I'll answer what I can with what I know. I average around 980Kh/s per card with these settings.

Setting excerpts for CGMiner.

--auto-fan --gpu-powertune 20,20,20 --gpu-engine 1025,1025,1025 --gpu-memclock 1500,1500,1500 --thread-concurrency 32765,32765,32765 -g 1 -w 512 -I 20 --no-submit-stale

After spending 2 days tuning my 290X Sapphire cards I got optimal parameters for my exact cards, hashrate is about 870 per card.....sharing with you, also wrote it in that doc

"intensity" : "20",
"worksize" : "512",
"lookup-gap" : "2",
"thread-concurrency" : "22528",
"gpu-engine" : "950",
"auto-fan" : true,
"gpu-fan" : "50-90",
"gpu-memclock" : "1575",
"gpu-powertune" : "30",
"temp-cutoff" : "95",
"temp-overheat" : "90",
"temp-target" : "80",

"api-port" : "4028",
"expiry" : "120",
"failover-only" : true,
"gpu-threads" : "1",
"no-pool-disable" : true,

"log" : "5",
"queue" : "1",
"scan-time" : "60",
"temp-hysteresis" : "3",
"scrypt" : true,
"kernel" : "scrypt",
"kernel-path" : "/usr/local/bin"

btw, highest possible TC was 28160, but than hash rate was only 750, best performance is at TC 22528. Optimal GPU eng and Memclock are 950/1575 for my configuration.

Tnx for help anyway  Wink

hi, what is your hashrate for the settings provided?

Expect 900k each card at the most for 290x.

Expect 900k each card at the most for 290x.

Iam using 1= R 9 290 x 1= R 290 and the R 9 290 trix -oc
my 290x is 985 khz and the r 9 290 (915 khz)

my trix (840 khz) is an problem because i can't use higer gpu-engine than 940, the card fails everytimes. I have the card allready 4 weeks and not working good. If you have an idea tell me please?

my setting is
-g 1,1,1 -I 20,20,20 -w 512,512,512 --gpu-fan 88 --temp-target 78 --gpu-powertune 30 --temp-overheat 90 --gpu-dyninterval 3 --expiry 1 -s 1 --no-submit-stale --lookup-gap 2 --gpu-engine 1031,1033,940 --gpu-memclock 1500,1500,1500 --shaders 2816,2560,2560 --thread-concurrency 32772,32772,32768

This way my efficiency is the best.

My friend asked me for aftermarket cooling for 290x, any suggestions?
Something with good price/efficiency ratio.
