use rivatuner to fix the fan speed.
i think your card temp will be lowered to 6+ at fulload.

it's not wrong.. just the cpu speed just ain't right...

yesterday i bought one 3850 for my friend.. got a chance to try on my system..
to my surprise the default gpu clock will give 9000 on 3dm06 result..
even for my 3870 end up 9600..

i'm on 3ghz cpu speed.. the default cpu just give me 7k on 3dmark...

if u can clock the phenom until 2.8ghz.. then the result will surely good..

for u guys worry about the temp... just set using rivaturner @ 50% fan speed.. with default bios fan spin is very slow.. that's why temp is high..
flash new bios should solve the prob... i got 60c onload now... last time 90c...

My advise is but a good cpu cooler, from what I know you can easily OC to 2.8Ghz.
That will help a lot. You should buy the BE version, more easier to OC. thumbup.gif

here's my 1k+ coreclock speed.

It takes abt 1.5vcore to achieve this speed bench-able, the temps never above 44c on load... but i dare not pump more. This is a 55nm core... anything more it might be dead lolz.

well... currently i have some issue with my motherboard memory timings and vcore, with proper tuning i am very sure im able to get at least 12-13k. You would notice my last timing on the rams damm cacat, this is an issue with my K9A2 Platinum, currently still discussing with MSI support team.

Will update soon once i am able to run my motherboard to its full potential icon_rolleyes.gif
