Couldn't wait. Upgraded to 3.1.1. All good so far. I'll give it 24hrs to make sure it's as stable as it was at 2.11.4. I tried 3.8.4 but it look like that needs an OS upgrade which I'm not prepared to do right now.

3.8+ don't support GPU mining. Stick to 3.1.1.

EDIT: OP, don't bother specifying shaders and thread concurrency, the latter overwrites the former.

gpu that low will throttle it, put the fan on 100% and buy some 120mm fans.

Try powertune 10

Okay looks like my biggest problem was using cgminer 3.7.2 instead of 3.1.1 . My second biggest problem is that for some reason my video card cant go over 1000 gpu core without getting hardware errors. I'm now running at 570 kh/s (which is a nice improvement over my 430-460), but it would have been really nice to break 600 kh/s.

Wolf0 you will definitely get $5 in btc and if no one can get me over 600 kh/s then you will get the full $10 (or if you can get me over 600 you can get the full $10). Can anyone help me get over 600 kh/s on my 7950? currently im using this my 7950 is my gpu 1

Use 1500 memclock, 1100 core. 1 GPU thread, 19 intensity. Thread concurrency 24064.

It submitted 1024 shares, it then got 4 hardware errors and crashed.

Try CGMiner 3.1.1.

I agree. I'm still on CGMiner 2.11.4. I should upgrade but I don't want to mess with it.

Are you serious? You know there have been speed improvements to the scrypt code since then, right?

I'm using cgminer 3.7.2

Yeah, stop. Use 3.1.1.

Thanks. I'll try it out tomorrow

okay switching to cgminer 3.1.1 and using the settings you suggested

Using your config It keeps starting off well hashing at 650 kh/s, is able to submit about 384 shares and then it just stops working. CGMiner then declares it sick. I'm going to try to lower the memory clock a bit and see if that makes it more stable. Intensity i'm using is 19.

Here's my settings. I have 3x MSI 7950. I get 650-670 KH/s, max temp 69, 250W from the wall, from each. It runs 24x7 and only stops when I stop it. GPU 2/3 were running much slower than GPU 0 until I lowered GPU 0 intensity to 19. Then all 3 GPUs leveled out at 650-670 KH/s (average, not max/min).

Try it out. I'd say set it to intensity 20 since it's not GPU 0

Ok I'll try this out right now

If you are getting crazy amounts of HW errors you have to lower your intensity.

I'm going to try lowering the intensity to 17 and will update

Ok I'm in the process of trying all the suggestions right now. Unfortunately when I get a bunch of hardware errors cgminer doesnt close properly and I can't even kill the PID so I have to reboot inbetween attempts. So bare with me

The person who gives me the tip that solves my problem will get $10-15 in btc/ltc/doge or if I have to combine multiple tips to get it to work I will split it up by who contributed most to get it working.

I also just appreciate the advice that you guys are willing to give me

Ok with your settings my hash rate does jump up to 630 kh/s but then my WU goes to 0 due to all hardware errors. Any advice?

How do I set the voltage on linux? I'll try the other settings right now.

Try just 24k concurrency, I 20, 1115MHZ on engine and 1450MHz on memory. I'm getting 650KH/s with those settings and a voltage of 1.087.

So I have a MSI 7950 and it's only getting 510 kh/s and WU is only 450/m. Here are the settings that I'm running with Cgminer.

My 7950 is gpu 1 so it's settings are in the middle of my 7870 cards which are gpu 0 and gpu 2. I bolded my 7950 settings

If anyone can help me fix this I will tip you some bitcoin, litecoin or dogecoin
