W3520 H20 @4877Mhz - DFI UT X58-T3EH8 !

02:22 AM

Time to really push my W3520 on H20 cooling still. Managed to break alot of personal best benchmarks for max validation, max uncore frequency achieved, 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

Super Pi 1M & PiFast @4802Mhz at 1.584v

Super Pi 32M @4794Mhz at 1.552v

Super Pi 32M @4677Mhz at 1.488v

Max Bclk Validation

So far 235bclk is max for validation. Messing with voltages to see if I can get more

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

hahahhahaah

i smell 5GHz

hehe I wish

I need to get past my current bclk limit of around 230-235bclk. over@locker886 did 254bclk on DFI UT X58-T3EH8 but used LN2 and way more IOH volts at 1.39v than I'm use to (max I've used around 1.25v).

ouchhh, bclk @ 250MHz isnt Classified territory? Oo

have you tried a sub zero or near zero cooling?

here is my 5Ghz on Biostar Tpower X58

under LN2 and its the limit for Tpower

Yeah highest bclk i've seen for DFI UT X58-T3EH8. I'd be happy with 240bclk for super pi 32M

Nah haven't tried sub zero on 1366 as my Kayl 1/4HP SS unit only has LGA775 mount/evap. Need to eventually get a 1366 mount/enclosure for the unit or get a colder unit ordered/built by Kayl hehe.

Haven't used DI/LN2 before either so still AIR/H20 guy mainly .. for now at least

Trying to see if can get more on bclk

Here is what I used to get 237 BCLK. I booted at 220 BCLK then SetFSB the to 237 BCLK.

Thanks ! will try booting from 220bclk and see if i get more

At >235bclk it's strange the mouse can still move around within windows but everything else is frozen and non-responsive hehe
