G80 SLI + Kentsfield benching

[Micutzu]

First subzero runs on this month's hot new hardware ... Qx6700 on Vapochill LS, G80's on water + ice. Kentsfield is very bandwidth limited and only 3DM06 really shines with it, and there are some problems still to be solved in order to do 3D at high DDR2 clocks, but things are starting to look good. Thanks to www.senorg.ro and to my benching partner xwoodoo

Setup:

eVGA 680i SLI
Qx6700 on Vapochill LS, Vcore = 1.6V
TEAM Xtreem DDR1000 5-4-4 @ ~480Mhz 4-4-3-8
2x eVGA 8800GTX water + ice, Vgpu = 1.58V
Tagan U25 700W

For VGA cooling i've used the same waterblocks made by crazypc.ro forum member blue_led that i've used on the 7900GTX's in the past, these are very very good and can handle overvolted G80's without breaking a sweat. Also, the 700W Tagan is a beast, proved to be just as strong as the bigger 1100W brother, the 12V rail dropped only 0.08V in load and this mainly due to drop on wires.

Here are the results:

3DM06: 21115 - http://service.futuremark.com/compare?3dm06=669258




3DM05: 26796 - http://service.futuremark.com/compare?3dm05=2357551



3DM03: 70147 - http://service.futuremark.com/compare?2k3=5074507

got pics of the rig ?

[Micutzu]

Only low-quality pics, made by a fellow forum member with his Nokia N70, here.

Nice! Have you tested how high FSB you can run with that Kentsfield?

[eva2000]

wow nice.. what's max fsb with 680i for kentsfield ?

[Micutzu]

Around 300-305Mhz is the max i can do with this Qx6700, it becomes unstable very fast over that; BIOS doesn't really make a difference, and neither Vfsb ... 1.3V is all that's needed. With Conroe things are even worse, 449.75Mhz perfectly stable, 450Mhz and over doesn't boot at all.

[elmor]

324 is max here (kentsfield ofc)

Micutzu: Try increasing fsb with 5mhz each time, cause this board has some serious troubles with fsb holes.

[maxxor]

319fsb is max here QX6700 Evga 680i XFX8800GTX

Nice scores there micutzu

That QX6700 is a killer in '06.

[Rovtar]

crazy scores
keep it up!

outrageous!!!!!!!!!!

[k|ngp|n]

Nice numbers in here so far Micutzu

[brickout]

any 3d01? noroc!

[charlie]

fantastic display of 03 power!!

[Shadowmage]

Nice numbers

3d01 thirded

[rick_fx]

That 3d03 score is awesome!

[Romano]

holy shiitt... that's insane!!!!!

[IliaKompGS]

Very good for freon+water.
But why not liquid nitrogen?

[Micutzu]

Thank you all for the appreciation !
'01 is very weak with Kentsfield, it's not a worthy effort.

TaPaKaH sniffed something hehe

agree. but not too late.
G80 pots are on the way

[bonzo_catalin]

agree. but not too late.
G80 pots are on the way

Wow , heavy stuff . Succes baieti !

[andre X_X]

how about the 12v rail on that tagan U25?? do you think 600w U25 could handle 2x8800GTX oced??

[Artem87]

damn great run...

[giorgioprimo]

realy nice test ...

may you post your setting on bios (Vcore,Vmem) to run this clock ?
