Re: Lowering mem clock to idle speeds SPEEDS UP Mh/s

Cool. Gained about 2-3M hashes by dropping it down to 339. 341 and 339 give me the same. Anything slightly higher or lower give me like 1M less.

This also decreased my card power by 20W, and temperature by about 5C! Grin

Currently running a single 5830 @ 920Mhz. Agression is at 7. At 11 I will gain a few more M hashes. I get 264Mhash/sec now.

Please try mem clk at this speed, 920/3 + 14, that's 320.66= 320 mhz & post how much Mhash/s u get.

At 920/320 I get 263-264.

At 925/324 I get 265-266.

You might be able to OC that all the way up to 960. Hell, I saw Frankiebits say he had his at 1000 for a while...though I couldn't tell you how he did that. I run mine at 960, and I seem to have one of the most unstable systems on the forum in terms of getting the speeds everyone else is. 960 is damn stable, though. Tongue

I get around 290 or so while using the computer, but I can't get my memory clock as low as I'd like. I'd say edge the core clock up by 5 and just keep an eye on it for a bit. Sometimes I'll launch like 3 Firefox tabs with YouTube videos just to make sure the system is stable before I OC it more.

Edit: If you do this, keep an eye on the temp. I use a tool called GPU Observer...it's a Windows sidebar gadget. Too lazy to link. Tongue
