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

where to download it?

See my post here: https://bitcointalksearch.org/topic/m.5352740

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

I'm in the same boat with 015.043 on my cards. No other BIOS files (including STILT's) are compatible with these cards. Sad

Best I'm getting is like 820KH or so, bleh...

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.

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..

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

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

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 ?

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.

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

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

I don't know what a modified inf file is so I guess not. Huh

This is my first build, so please don't laugh if that was a stupid answer.

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

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.

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

@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.
