its not water cooled and i OCed my memory because, and I am not trolling you with this one, i just get a bluescreen if I OC gpu but not the memory, don't ask me why.i just figured it out by playing a lot with the after burner. but to be fair, i can only sustain those hashes for about 2 hours, the card gets unstable and crashes then, but when i turn the cpu clock down a little I stell get 770mhash/sec and the card has been stable for about 2 days now.

currently i am at work, but i can upload a screenshot later if you want to. 5970 can potentially hash over 800.

Seems right, i'm mining on an air cooled 5970@730 MHz and i'm pulling 700-720 MH/s. Using a good liquid cooling I guess you can go stable over 800.
On the other hand, with the 200$ for a good liquid cooling you can get an additional 300+ MH/s GPU.

5970, really? Maybe you should check your clocks, they're probably like 157/300 Smiley

I have 5770 at 950/310 getting 210 mhash/s and 5850 at 915/310 getting 365 mhash/s. Stock voltages, stock coolings both.

there is really something wrong here...
Open AMD control panel and go for the last tab. Check the workload on all your GPUs (should be 4) and report them back here.

450Mhash from an ASUS 5870 @ 975MHz Core 900MHz RAM

that's impressive - I'm only getting 400 but I'm only running my core at 910Mhz - what temp are you seeing from your core running at that speed? - I'm scared to go much higher than 75...

About 21 Mhashs/s on my GT430 (oc: 810 / mem standard@900)
Both using puddinpops cudaminer.

Graphics cards are designed to go much higher than 75, people run them past 90... on mine the card will not attempt to slow down untill past 100

340MHs on a 5830.

Core 1030 / Mem 340 Stock volt, air cooled. Using Phakt kernel, Worksize 128 fastloop off

63C Shader Temp with PCIE slot base Frequency upped to 102mhz and an ambient room temp of 71F

Unstable after about 3 hours, so bumped down to 960 with the same memory and am getting a stable 288MHs.

NICE! What brand was that 5830?

Sapphire Xtreme 5830, purchased from newegg.com before I even knew about this bitcoin stuff.  Grin

It was unstable if the machine was used, so I bumped it back down, I was worried something might happen when I was away.

Don't want to come home to a smoking case.
