Home made 3-Way SLI results

[PoorManPcreview]

Try with Xp for better scores?

[ZoLKoRn]

Finishing up now. This is working.

For phase change users, 780i is the best. bios changes without power cycle is a definite plus.

Half multiples work 12.5 is the max multiple working for both QX9650 and QX9770

Ill have my numbers up in a few hours along with more info's.

Ahhh It works on Windows Server 2008 ? and what driver version is your using ?

Thanks

[Sampsa]

Hello Sampsa, what Vista version on your install it's Ultimate or other and
it need to update hotfix ?

Thanks for sharing it looking goods

Using Vista Ultimate 32-bit.. no hotfix (yet, just downloaded it)

[over@locker886]

Yes and QX9770 but no nForce780i SLI board.

Thanks your answer!

I have nf780i but only have wolfdale (fsb limit).
I heard NF780i officially no support 45nm quads! What did you hear?

I would like do sli test later with yorkie, but if no support.....back CF..

Vista drivers work for everything so far in 2008

Vista 8800 ultra 169.25

What you mobo using? What is the max fsb?

Sweet Sampsa! Nice to see some 03 action

[dpa]

this is cool.. hehe, what about 06 sampsa..?

[Sampsa]

I modified all three Ultras today (vGPU 1,35 -> 1,44V) and managed to raise GPU clock from 660 MHz to 685 MHz, I also installed Vista 945149 hotfix for Multi-GPU scenarios (http://support.microsoft.com/KB/945149), adjusted High Performance setting instead of Quality from Control Panel () and raised HTT speed from 240 MHz to 300 MHz (thanks for the tip Kinc).



Thank you everyone for your great support on this (except NVIDIA).

I'll aim for Un-offical 3DMark03 WR later tonight with higher CPU speed and I also try to squeeze those few of extra-MHz from graphics cards

[massman]

How much do you estimate that is left in the system at full speeds? Are we talking about 115-125k?

[Zeus]

Very well done Sampsa!! 100K broken without the aid of a Yorkie.

[Sagart]

Nice Sampsa!

As dpa I want 06-results!

[Rovtar]

hm sampsa and nvidia?

strange..

goood work anyway

[dpa]

Sampsa! Have you adjusted the pci-ex ports to 125-140Mhz...? That will help alot....

[Sagart]

Sampsa! Have you adjusted the pci-ex ports to 125-140Mhz...? That will help alot....

For what?
Will the cards clock better?

[M3kk]

+ marks .

[Oliver]

Looking really good.

Keep pushing it.

[Vatos_locos]

For what?
Will the cards clock better?

it will increase the Pci-e bandwidth so the the score should bump up a little

Sampsa really nice work there

[George_o/c]

Sampsa congrats man, looking good
I think it has some serious potential, with an increased PCi-E frequency and the QX6850 @ 4.9GHz under LN2
Keep up the good work !

P.S. How on heck did you figure out the 3-way SLi using the old bridges only ?

[SKYMTL]

I really wonder what is holding him back from 3DMark06.

[Solarfall]

excellent work sampsa.. hehe they dont call you a legend for nothing

[George_o/c]

@Sampsa: Is that Vcore real ? Only 1.688Vcore for 4600MHz ? It's kinda low ... which is of course good
What was the cpu temperature under this little monster-cascade () ?

[Gautam]

Grats on 100k!

[George_o/c]

I can see here that the highest 3D Mark 03 result at HWBot is a 99000 run from hipro, done with a X6800 @ 5250MHz and 2 Ultras on LN2 ...
Sampsa's 100k run might be unofficial, but still he broke the 100k barrier ... Now, how would they perform with a yorkie on LN2, hosted on a 780i m/b ... ? ...

[Sampsa]

thanks everyone,

PCIe bus is of course overclocked. Haven't noticed much difference between 125 and 135 MHz.

3DMark06 is almost completely a CPU benchmark so it is no fun with Kentsfield QX6850 and nForce 680i SLI motherboard. With nForce 780i SLI board and Yorkfield you'll see interesting 06 scores though.
