I'm using PowerColor AX7850 2GD5 now at 350kh/s.

Anyone else using it? Di ko maabot ung 404kh/s na nakalagay sa litecoin hardware chart.

Thanks

I'm running two of those.  Runs 370kh/s when clocked at core 1100 and mem 1300 on BAMT, 368kh/s sa win7.  Those 400+ hashrates are heavily overclocked, malamang hindi stable yung mga iyon or malamig yung lugar (A/C, cold weather).

390kh/s na ung sakin ngaun sa sgminer win7, tc 12228, gpu-engine 1150, gpu-memclock 1250

Nice!  i'll try that.  Naka autofan ka?  anong fan rpm mo at 75degC?

[nonsense91]

taget temp 80, gpu-fan 60-85, sa ngaun 2881rpm @74c

dati 40-85 lang fan ko, pero hanggat maari kasi ayoko paabutin 80c temp ko, pag binaba ko temp-target sa 75 bumababa ung kh/s

ok lang masira fan pwede naman palitan ng aftermarket cooler

your oc settings are too hot for my setup, becomes unstable. i'll try working my fan targets, hopefully i could squeeze more hashes. with the same settings, sgminer just runs as fast as cgminer.

sharing my new config, baka lang ok din sa inyo... 400+ kh/s

OS: Xubuntu 12.04 LTS

software: sgminer 4.1.0 by zuikkis

kernel: zuikkis (have tried ckolivas, psw and alexkar but zuikkis is the most efficient)

Option A: GPU threads = 2,     403 kh/s

tc = 4097, engine = 1150, memblock = 1350, intensity = 12

Optin B: GPU threads = 1,       391 kh/s

tc = 8197, engine = 1125, memclock = 1350, intensity = 17
