Okay So Im running 2x 7970 xfx

Win 7 64 bit
cgminer 2.11.4
No cross fire
Driver version: 12.100.17.0
CCC: 13.3 beta 3
SDK: 2.8
Core: 1025
Mem: 1800
Voltage: 1.170

I cant get it to stop giving me HW errors!!!

When i run it with no extra settings it gives me HW errors..

I am going INSANE I cant figure this out...

First, go here: https://github.com/litecoin-project/litecoin/wiki/Mining-hardware-comparison

Second, get 13.1 Catalyst, it's the best for mining LTC (currently).

I'm assuming that you are trying to scrypt mine. I screwed with CGminer for a while trying to get it to work but eventually gave up and went to GUIminer for Litecoins. It is surprisingly efficient for me. I'm getting about 625 kh/s on a 7950. I have it clocked to 1075/1525 @1.125 volts. Remember, it's all about getting the right balance between the core and memory speeds when scrypt mining. If I change my core speed to 1050 or 1100 my hashrate will go down. What I did was leave the clock speed at stock and increase the memory to it's highest stable frequency. Then I increased the clock speed small increments at a time, until my hash rate started decreasing. Then I found the lowest voltage my card would be stable at running those speeds. I am running on the 7950 high usage preset, except i turned the intensity down to 19. It is stable for me, but YMMV.

Switch to Phoenix 1.7.5.

It's the only miner that doesn't give me any hardware errors. I'm using the one that is bundled with 50 miner.

Wait, are you mining LiteCoins... you said 200KHs... Then ignore my memory comment. Litecoins are heavily memory intensive and demand more from your card than bitcoins. Don't expect speeds over 11 without specific modifications to configurations, for those specific cards.

If your speeds are 200MHs and the K was a type-o... then you have other issues, because that card should get about 600MHs on bitcoins, with stock settings at speed 7-auto.

The higher your clocks, the slower your "speeds" have to be... you can't just crank everything up to 120% and expect it to work... The purpose of clocking is to make it efficiently stable. Not just to crank up the volume and HOPE for it to work. Liquid nitrogen cooling, possibly, but not with stock fans, inside a computer case, on an overheated wasteful CPU also spitting out heat, and ten fans also adding heat and just recirculating hot air in your case...

We need more details than just numbers... Photos, other specs... processor, PSU, available watts... ambient room temperatures...

What speed is your memory at? Stock clock on your Black Edition is just 1425, you appears to be running it way over this, which introduces a lot of problems for no gain at all on Bitcoining.

Fix that then try Phoenix 2.0 miner, its the only miner I could get to run on a HD6950 that was doing the same thing.

Do you have a 750Watt powersupply, and adequate cooling?

Mining at speed 11 is HIGH. You HAVE to have an "already stable card", at that speed.

Try lowering your voltage, lowering your clock-GPU, lowering your clock-MEM to 150... That will "help"... but try sticking to the default 7-10 for mining speed, unless you have water-cooling, adequate air-cooling, decent power, and "stable cards"... Obviously, your cards are unstable, so reduce to a stable setting.

Try 13.5Beta and 2.7 SDK,cgminer or bfgminer or biablo miner.

OKay i got it up to 200kh/s a card.. But i cant turn the intensity up more than 11?? without it starting HW errors
