Trying to take down the big boys (Andre) in 3DMark 2006. Quad GFXS!

Awesome!

Big numbers!!

Yesterday we had a first test with Classified E760 and our Xeon W3540 together with ln2. We could reach this:

Unfortunately efficiency isn't really good. But we have to deal with a horrible coldboot-bug at -27 degrees. Once the system is up and running we can reset and reboot normally. But once we change uclk, memory-timings and/or qpi-settings, the system shuts down completely and we only can boot again when the temperature is at -27 or less.

So we just set "safe" uclk and memory-timings and started to look for max frequency of our xeon. It passed cpu-test at 5,460 mhz but at full run it only reached frame 39 of cpu-test #2. So maybe with finetuning we can pass the whole benchmark at this frequency.

20 points~

Yeah, we noticed that you are only 21 points ahead. But I think you are safe for the next few weeks. We have a few litres ln2 left (maybe 15 litres) but the next two to three weeks we don't have time to bench.

If we can tweak the whole system right I think we can come close to 38k with it.

[hipro5]

ALL of you, are lossing the Crossfire at GT3....
Run it alone or pick it with the GT4 to run them together and you will see what I mean...

that cpu score is high!! any tweaks? got a 760 myself now, but no time to test.. very nice scores Jens!

[dpa]

I just tested the E760 fast on LN2 with four 4890s.. I think I got the EXACT same score as hipro in 06, at a tad lower clock.. 5.3Ghz cpu.. screen is ofcourse on the bench harddrive, will ship it over as fast as possible.

I bumped the uncore up to about 4200Mhz on this run, but the coldbug appeared earlier than before, I was at -115C when it started bugging. I ran about -140C before, anyways.. I will test this board some more, seems to my that 100Mhz = 1000 points in 06.. 38k should be very possible at 5.4Ghz.

[AOCTeam]

Was waithing for some updates from you. Glad to see you back on your rig after EM.
Hope you make 38k soon!

[hipro5]

dpa M8.......Uncore is one secret to get high scores...
I've spent ~ 440lt+ of LN2 ONLY for 2k6....

[The-Fox]

George you are one crazy guy !
The world is soon to be on LN2 crisis if you keep on going that way, that is truly insane man !!

That sounds like the IMC coldbugging rather than the processor core. When you hit the coldbug at -115°C, did you try increasing the uncore frequency and/or uncore voltage (VTT)?

[hipro5]

@ Sampsa: This is with the 9.6 Drivers - because I don't see anywhere in FM that are approved and I see yours are approved....

They are approved, but not yet updated to their site. Try yourself

OK - Thanks...

lol, 440lt.. haha..!

this still is not my best score.. but if I can manage to run this cpu at same settings and 5.4Ghz+ I will break 38k with a blast

the E760 IS faster than my old E759, tried some 4.2Ghz action, and it runs 200-400 points faster.

going for 5.38Ghz later, ran cpu tests at that yesterday

I ran high VTT for this, but havent tried to bump the uncore YET.. iam having the -60 coldboot thing.

[massman]

how high is high?

[dpa]

how high is high?

I believe its about 1.57v.

[massman]

1.57v should be enough to warm up the IMC at least a bit; I reckon that, as you say, bumping the frequency might help. Or else you can just go bezerk on the VTT,

ill give 20x a run later... just bought a 24 pack of kneaded eraser

[massman]

If 20x doesn't work, test 21x or 22x ... uncore multipliers on i7 are weird

just hoping I have enough LN2 for all that
