QUOTE(vickyrao @ Jan 8 2008, 05:11 AM)
would like to find out with u guys...

my spec:
amd phenom 9500 2.2ghz stock cooler
2gb kit patriot 800mhz high performance 4-4-4-12 2.2v
msi k9a2 platinum 790fx chipset
msi oc edition ati3870 512mb x2 (crossfired) stock cooler
silverstone zues 750watts psu
500gb wd 16mb sata2

running on windows vista ultimate

3dmark06 score:
without cf: 10k
with cf: 12k

is this normal score? if yes, how to make it perform higher? if no normal then what is wrong?

secondly, temp is 72deg for ati3870. why is it high? should i change the cooler? if yes, then what cooler is reccomended?

sorry for the noob questions as im kinda new to this nexgen system.

@vickyrao,
i think my gpu is same with yours.
the default fan speed is only 30%. rclxub.gif
you can try to use rivatuner to adjust the fan speed to spin at 50%~60%

[attachmentid=375575]

you can check my temperature is only around 60'c when running 3dmark06, and 44'c idle... smile.gif

@AoiNatsume
my card max out at 855Mhz/2700Mhz, i think i cant break > 860Mhz without flashing bios.
However until now i still dare not to flash the vga bios.
Btw, how many percent of the performance improvement you get from flashing bios to oc till > 900Mhz?
