Thx, but i will change the defaultcoolers to some watercoolers, because the temperatures are very high. but only the upper card. the is place between the card is little.

[Supertim0r]

no sli bridge ?

[SeLecT]

This was a Pic before SLI, the SLI-Bridge came the next day. Now the rig run with a bridge

So, a few minutes ago, i've ordered two watercoolers for these cards.

Hey SeLecT,
your Singlecard Scores seem to be a bit low.

My Hardware:

Pentium D 945@4.8ghz
Gigabyte Ga-G1975X
XFX eXtreme 7900GS 480M @ 615/840
G.Skill 6400CL4D-2GBJS

125k in Am3
10k in 05
5,7k in 06

Which drivers did you use for single card benches?
I used nVidia Forceware 92.91 beta...

Best Regards
Dennis

[SeLecT]

i used the 85.96, when there is another driver i can use, tell me

my benches with a single card was with lower clocks: 500/700.
When you look at your clocks...

i've tested with one card and oc: (3600Mhz - 550Mhz/845Mhz
AQ3: ca. 142000 points
3D Mark 05: ca. 9500 points

So, i think my scores are ok.

[SeLecT]

This is my new cooler, but the postman bring only one cooler, so i must wait until the shop send me another cooler. so, i must wait with test, etc.

[SeLecT]

Here they are. Now the postman bring me the second cooler an this is my new rig. quiet an fast
