W3520 H20 @4877Mhz - DFI UT X58-T3EH8 !
Time to really push my W3520 on H20 cooling still. Managed to break alot of personal best benchmarks for max validation, max uncore frequency achived, Super Pi 1M, 32M and Pi Fast on i7/X58 platform :)
- Super Pi 32M HT Enabled max = 4677Mhz at 1.488v
- Super Pi 32M HT Disabled max = 4794Mhz at 1.552v
- CPUZ Validation HT Disabled max = 4877Mhz at 1.584v
System:
- Intel Xeon W3520 3845A935 D0 (Xeon equivalent of Core i7 920 D0)
- EK Supreme LT 1366 / FESER 480 / MCP655
- DFI UT X58-T3EH8 04/28 beta
- HD4870x2 (HIS 4870X2 to Asus Top bios) with ATI WinXP 9.5
- 6GB Corsair Dominator GT DDR3-2000Mhz 7-8-7-20
- 750GB Samsung SATAII
- Silverstone OP1200 PSU
- Triple boot - WinXP Pro SP3 / Vista Ultimate 64Bit SP2 / Win7 Ultimate 64bit RC
Max Validation @4877Mhz at 1.584v

Max Uncore Frequency @4645.6Mhz

Max Bclk Validation
So far 235bclk is max for validation. Messing with voltages to see if I can get more :)

Thanks :)

Will try higher clocks this weekend as forecast has some nice cold night time weather coming my way http://www.weatherzone.com.au/local/...=aploc&lc=9647 :D

WOW
nice start George :)

i only play Core i7 9XX but these Xeon are tempting

Realy nice chip and great results on wc:D

nice going george! Was your SS tuned for C2D? I wonder how it would hold these chips?

Kayl 1/4HP SS was tuned specifically to hold high load with warmer not too cold temps for my FX-60 s939 to get around AMD cold bug. It came with only s939/LGA775 mount enclosure etc. So no 1366 mount etc. Probably get Kayl to fix me up with 1366 enclosure/mount kit and/or get a more beefier unit built later on. But for now H20 is it for 1366 :)

Killer Result Eva, as always :up:
Those Xeons are nice chips for sure.
Now you need to subzero that poor chip and see what it can really do :D

No sub zero only H20 for now hehe

Love that cpu, 4870MHz on H2O is definitely something to be proud of ! :up:

I'm gonna agree with Xavier though, you need some subzero cooling. :D

One day i'll so sub zero on 1366 cpus.. one day hehe

Now that I started testing my uncore frequency overhead on W3520, thought I'd see how far I can push it on regular water cooling.

Dropped bclk to 210-214 and bumped uncore multiplier from 16x default with 8x mem multiplier, to 22x uncore multiplier and managed to push it to @4663Mhz uncore frequency Super Pi 32M stable, @4707Mhz for 4M stable and Everest and screenshot @4760Mhz uncore frequency !!!! Had to jack up both CPU VTT and VDIMM voltage to reach such uncore frequencies :)

Uncore frequency = 4663.5Mhz

http://fileshosts.com/intel/DFI/DFI_...3s219ms_tn.png

Uncore frequency = 4707.8Mhz

http://fileshosts.com/intel/DFI/DFI_...9s453ms_tn.png

http://fileshosts.com/intel/DFI/DFI_...everest_tn.png

Uncore frequency = 4760.2Mhz

whats the difference between a 920 do and an e3520/w3520
06-05-2009, 07:16 AM
eva2000

average w3520 seems to clock a bit higher than 920 D0s it seems :)

how much vtt did you have to give? I am jealous, pushing uncore has been somewhat tough on my w3520...very nicely done!

Not agreeing or disagreeing with you EVA, but I don't believe I've seen a W3520 do 5279 Mhz on dry ice:

In my experience the Xeon equivalents seem to do somewhat better in the OCing department.

That's why I'll wait 2 more months for the W3550 (i7 950 equiv) to hit the store shelves.

cpu vtt in screenshots for SG VTT = CPU VTT :)

Clearly you're not looking hard enough W3520 @5362Mhz, @5215Mhz x2 by other folks :)

Is there going to be a W3550/3560 ?

I don't think anyone can say if W3520s are better or worse than 920 D0, both have validated amazing results. I stand by my statement that I know of no w3520 that has validated as high as 5279 on Dry Ice. The 5362 Mhz validation is extremely impressive, even if it was achieved on LN2/cascade.

I don't think as many folks have them. If they did, I think you would probably see better results.

on hwbot stats

Xeon W3520 = 30 results averaging @4695 clocks
Core i7 920 = 400 results averaging @4217mhz clocks

but i7 920 include c0 and d0, but still not many folks using W3520 so too early to tell :)
06-05-2009, 09:45 PM

Agreed, I've always considered them to be neck and neck, but that's just my hunch.
Your 4877 Mhz at ambient temp is spectacular, and that's a fact. :)

Yeah for validation okay. 8 core stress though limited by cooling hehe

Pushed the system a bit higher for wPrime v1.55 from 4500mhz to 4600+mhz but used Windows Vista Ultimate 64bit SP2. Limited by water cooling seems as 1024M @4664Mhz fails around 77% mark into the run :(
