Radeon HD 6770
-
Hello,
I have 2 Radeon HD 6770 GPUs going and I’m currently getting 150KH/s on one and 75 to 100 on the other. Both have the same configs and I’m using cgiminer on windows 7. Does ram and cpu make a big difference? That’s the only thing different between the two boxes. What kind of hash rate should I expect?
-I 18 -g 1 -w 256 --thread-concurrency 8192

Do you have a monitor plugged into the one under performing?
Sometimes in Windows you have to make a dummy plug as a terminator if you’re running headless.

my 6770 gets around 130 khash/sec, so your 150 khash sounds very good.

Hi sir,
I got mine Running on 200 Khash/sec.
this is my config:set GPU_MAX_ALLOC_PERCENT=100
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1cgminer.exe --scrypt -o stratum+tcp://pool.d2.cc:3333 -u NAME -p PASSWORD --intensity 16 --worksize 256 -g 1 --thread-concurrency 6016 --gpu-engine 895 --gpu-memclock 1300
I hope it will help you out!

A while back I had a 6770 that I used when I was mining Litecoin, until my order of 3 HIS Ice-Q 7950s came in.
The 6770 did well for what it was, I was able to squeeze it just over the 200 Khash mark, something like 201-205 if I remember correctly.
Morderchai - how the hell did you ever come up with 6016 for a TC? TC’s should be divisible by 256, not by 64, as has been commonly stated.

I used this tutorial;
https://teksyndicate.com/forum/litecoin/how-tweak-your-settings-and-squeeze-khs-out-your-card-using-cgminer/137706where it stated that you needed to create a file which would give you a number (in my case 6016) and you needed to add 2048 untill it would crash. so thats what I did.
I’m pretty much a noob so if you could point me in the right direction that would me greatly appreciated and rewarded with rep ofcourse!
