    then again...in saying that i just looked through some old screenies, my gpu score at stock speeds used to be around 20-21k, now with these drivers at stock it's 24k - which is what I used to get when overclocked. Funny that theres slim to no gain now though huh? somethings fishy is goin on.

    you may want to consider flashing the bios of your 5850 to unlock the clock limits, that way you won't have to use the unofficial overclocking method and maintain powerplay. I find it better to have my card switch between 2d and 3d clocks, that way I can apply a manual power plan to have the fan run at 33% at 2d and increase accordingly as 3d clocks are activated

    if you're unsure on how to flash the bios manually, there's this new great tool that is n00b-friendly called Radeon Bios Editor

    Enmity try lowering your oc a bit if score is worse ..that means you exaggerated with oc and card is 'defending itself' like that

    i play at

    core: 1020

    mem: 1220

    voltage: 1.299v



    I play Crysis in 1280 x 1024 , gamer quality at 71 fps

    man u don't need to oc your card ..at that resolution cpu is limiting you

    I thought that it was only the memory that "defended itself" like that when it's pushed too high - rather than completely crashing, 1200 is the highest i push the memory which is 5870 stock speed. Since the 5850 has the same memory it should have no issues wit that speed. Come to think of it I think I actually did lower the memory to 1150Mhz and got the same **** result lol. However I'll give it another go at 900/1000 to see if that helps. What voltage are you guys finding u need at that speed? I've got mine at 1.212v for 900 core.

    Perhaps I need to crank it to 1.25v?...I shall test some more.

    Edit:
    Also, temps are no issue either, I use a custom fan profile which keeps temps under 70C with furmark at 900 core.

    Hi guys i just started to OC my 5850, im running at 825/1200 dont wanna ajust voltage. I tested with kombuster but could not see any artifacts but when i did the occt gpu test i got some errors. I have never had problems when gaming at this clock tho. I have my PII 955 running at 3.7ghz and my res is 1600x900 so i dont think theres a bottleneck there. What is the best way to test for stability? i keep upping the memory freq and it seems to be stable which i find odd, do these stress tests actaully test gpu memory?

    many thanks

    Mine is running 1.162v for 901/1200.

    No probs with those settings, however lower voltage will result in gray screen crashes.

    i run mine @920/1200 with 1.2v ..I decided somehow that that is limit for voltage :) (don't ask how)

    @liamcrane

    the best way is by playing games :) ..anyways, you can do crysis warhead benchmark, like 10 loops for instance, that should suffice

    after some more playing, i upped the voltage to 1.25 and ran vantage at 900/1000 - got 24k7 that time. So i upped to 900/1200 1.25V...got 23k3 - so my memory is crap by the looks of it haha. Thats a lot of volts for only 900 core though huh? ...maybe i'll up to 950 or so...coz gpus never went over 60C :)

    Any guys running two 5850's? what's your gpu score? getting over 25k?

    nice bro, this is my latest...seems fully stable at 1000/1125 1.299V - i've just benched a lot of games and the hottest my cards got was 67C. Pretty sweet. Im gonna make a new thread about that though. Heres the vantage score...i just left the cpu at 3.6 hence the crap cpu score haha.

    I get 25271 without really pushing it. Don't know how to get the standard picture again, this is from what I've saved on the Futuremark site (ORB).

    EDIT: Sorry for the double post. Wanted to edit, and I can't figure out how to delete this message. :(

    EDIT2: Stats are on the left, so 775/1125, max for ATI Overdrive using Catalyst.
