Hi
Does anyone have some good settings they can share for the 7950 video card, for CGMiner. I'm using getting 576kh/s but I read that my card should be getting a lot more
If I set my intensity to high it crashes right away
Try this:
-I 19 --thread-concurrency 24000 --gpu-powertune 20
From:
https://litecoin.info/Mining_Hardware_ComparisonThat should get you around ~ 670 kh/s make sure your GPU fans are at 85% at least or else you will burn out the GPU over time & watch the temps Don't go over 80C they can go higher but you want your card to last right
Thanks ill try that

Not a lot more... a little more
some 7950 will do 670 Kh/s heavily overclocked, but i won't recommend it, temps and consumption are much higher, overall i donīt think its worth it.
I usually do 600-610 KH/s with temps around 70-72C, these are my settings using CGminer 3.7.2 kalroth
--xintensity 4 --worksize 256 -g 2 --shaders 1792 --gpu-engine 995 --gpu-memclock 1250 --gpu-powertune 10 --thread-concurrency 16384
You can try to increase --thread-concurrency , every card is a little bit different.
Iīm using a modified bios with core voltage @ 1,081 V instead of stock 1,25 V, for lower wattage.
If you are using stock vcore voltage you can try to increase --gpu-engine in 5Mhz steps until drivers crash, then go back 10Mhz.
Thanks
I'll try your settings, out of curiousity why is the thread concurrency so low on yours?
I heard many 7950 should run at least 20500 for that setting but as you said I realize that every card is a little different & at the moment my card is stock just turned up the fans with GPU-Tweak
The more stream processors & GB of memory your card has the higher your thread concurrency can go, you should do at least 23,000 with that video card.
I've seen many people reporting good kh/s with those settings and intensity @ 20 with fans @ 100% and
good case ventilation will ensure your video card lasts many years not just a few months.
If you have poor case ventilation you could take off the side of it and that helps let the hot air get out. Or
get a small desk fan to blow on it. Also get those little cans of compressed air and do it on your video card every 2 months you'll be surprised haha they can collect a lot of dust especially if you smoke blunts all day long like I do lol
