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 ? http://s18.postimg.org/a9blnq721/error_r9_290.pnghttp://postimg.org/image/6cy9rqm2d/

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.

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