[Solved] Very low hashrate for mining Litecoin with cgminer and BAMT

[Brunic]

Hi!

I'm looking to move my Bitcoin farm to Litecoin. Using this guide:
http://www.bitcointrading.com/forum/linux-distros/bamt-version-0-5-easy-usb-based-mining-linux-with-farm-wide-management-tools/msg1835/#msg1835

I've successfully installed cgminer and the required SDK. I can mine with my GPU, everything is detected and fine. The problem is, I can't go over 5 Kh/s with a 5770 or a 6770 (my test GPUs).

I've tried playing around with this:
https://github.com/ckolivas/cgminer/blob/master/SCRYPT-README
I've tried different values, adding, removing parameters, but it doesn't seem to make any difference. I'm stuck with really low hashpower.

My test rig has an Sempron 135 and 4G of RAM.

I've also entered the three "export" commands before starting cgminer. I use cgminer 2.7.5. Any advice is welcomed.

Thanks!

How big is your farm?

18 GHash for Bitcoin.

I want to mention I've found the "problem".

Don't use the 2.7.4 or 2.7.5 version of cgminer, you'll get stuck at 5-10 khash whatever the GPU or the settings. I've used the 2.6.1 version of cgminer, and it mine normally. I can't explain the bug, just avoid those version of cgminer with BAMT 0.5c.

I don't know if the problem exist in other OS.
