Pretesting Sapphire 5870's
 
I got the nice occassion to play some with these cards... at the moment still figuring out which OS is best to run on :

Starting off with Vantage :

Single card :

Windows 7 32bit : slightly higher GPU scores, lower CPU scores : first run after a reboot is always the fastest. Fastest total score out of 3 benches compared to the 64 bit version. Difference though was max 70 points :D

Windows 7 64 bit :
GPU scores remain plus minus constant, CPU score is also a tad faster than 32 bit OS.

Crossfire :

only one option to go 64 bit OS... with the 32Bit version I have loads of graphical glitches with the current driver and sometimes Vantage just caps out (though FPS seemed a tad faster again then the 64 bit OS...)


Tweaking Vantage : Messing with the different settings in the Control panel didn't give much , only selecting edges in the smoothvision tab usually gave me another 30-40 points over any other setting I applied/changed... I hope the other benchmarks are more responsive to tweaking... These cards seem so CPU limited... (running 3.2ghz on the boxed cooler at the moment)

I STOPPED TESTING AS THESE DRIVERS ARE SOOOOOOO BUGGY, WHY ON EARTH TO YOU RELEASE SO FAST CARDS IF YA DRIVERS CAN'T EVEN DECENTLY ACTIVATE CROSSFIRE not even in screaming old Windows XP...

Time to get to work Terry !!

I can assure you it's absolutely not !! SLI is fun, Crossfire is the suck :p

Hopeing for Gamer for better drivers

Flashed the card to the Asus bios, to overcome the 900-1300 clocks.
Now my board just shut down when stressing it in 3d marks.
Could that flash be the cause ?

Massman 7th October 2009 16:38

Overheating?

Gamer 7th October 2009 17:14

Nope, seems like that heatsink Leeghoofd gave me is no good :(
Not touching the IHS.
Phase changed that :)

/edit :
1000/1300 = pass 06

higher = artifacts.
I can live with that.
