thanks pvhk :)

Not as impressive as all these D0 stepping results we are now seeing, but my old 3836A756 batch i7 920 is doing quite well moving from TRUE120 air to water cooling - easily improved on HT enabled max 32M pi from 4473mhz to 4618Mhz http://i4memory.com/showthread.php?t=17002/ !

Amazing what a water cooling can do for max stable bclk too. On air 228 bclk was max for 32M pi, but on H20 straight boot from bios 32M done at 230blck with ease!

maybe if you run with i7 920 D0 you can fly higher BCLK George...any way nice result again...:up::up:

hey eva did you try if raising the pcie frequency helps at all in stabilizing your system and maybe help to push your cpu even further ? i keep mine on around 110mhz :thump:

Yeah from what I've seen need D0 to go higher heh

Tried up to 110mhz as well which seems best for 32M :)

Nice work Eva... Impressive stuff. I reckon you can still get some more though out of that DFI baby lol :up:

hoping so since max 32m ht disabled only improved from 4652mhz to 4680mhz from air to water hehe - was hoping for at least 4700+ 32m pi heh

nice speeds there eva...I'll have to start working with memory timings now that Im happy with cpu clocks ;)

interessing thread , many thank georges :)

You have help with your setting before and me for screen at 235.8 x 21 with my 920 C0 3836Bxxx under DOD (-43°)

I search the good setting for up at 240mhz maybe , i need test after 2 965XE for see if my 920 is limited or the motherboard , wait & see :)

awesome stuff.. I forgot to update i'm 230bclk 32m stable now with new 4/28 bios along with new PB for 235bclk all on water cooling

Been playing with DFI's latest 4/28 pre-public beta bios and it seems to have improved memory clocking stability for Elpida IC modules as well as improved my max H20 cooled bclk validation from 233 on 3/28 pre-public beta bios to 235bclk on 4/28 bios. 4/28 is pre-public beta so flash at your own risk from here.

nice bclk eva :) Any plans to see if subzero could get 235x21 32M stable?
05-05-2009, 01:41 AM
eva2000

Do have plans but long way off as I need to get Kayl to do a new 1366 evap mount for my 1/4HP SS as it was made back in day for s939/lga775 hehe

next big plans are for Corsair DHX TEC memory cooling and Dominator GT review :)

sweet... all these D0 are tempting me... but I still like my C0 hehe.. might wait to see what 950 cpus bring to the table heh.

looks like you're really having fun with this setup again eva :)

thanks sure am.. nice oc_windforce D0 seem to have potentially higher bclk! :)

Good baseclock, your cpu pushing up on VTT termination table as same my D0 3847A891. When I have tested this cpu I have find this fact, only depend on scalability of IMC versus VTT, if your cpu is hot and ambient temperature you have more possibilty to gain fsb if you cooling it.

For example my cpu on classified take 239 on base clock with 1,55VTT with chiller, cpu temp is around 25°Celsius with real temp monitoring. Same cpu on bloodrage, without pciex 110, take 229 on base clock at 1,50Vtt more vtt on blood not give any difference why it not have fixed the pciex in bios option.

On Asus Gene my cpu give 231mhz on baseclock with pciex 110mhz and vtt 1,55V. On Asus my cpu lowering base clock why Asus maonboard have many problem to menage correctly the VTT line amplitude, this mainboard needs more vtt voltage respect DFI, classified and bloodrage at same frequency of base clock.

Third fact to limit the max.fsb is memory module you use, example with kingston 3x1 giga elpida hyper single side my cpu take max. 225mhz on bloodrage and with kingston t1 3x2Giga ever elpida hyper, but this model is double side chip, my cpu take 229mhz on baseclock with this. I supposed that this depend only on the Vref. Voltage set the minboard on imc memory controller of i7, because this module is more stable with lower Vdimm voltage respect the module 3x1, and vref change in base at Vdimm Voltage you apply in the bios.

Good testing guys.....:up:

so do I, i was attempt to bring up my D0 stepping to the max limit :D:D

hehehe, i just came into the Xtreme OC'ing section and the top 8 or 9 threads are all Classified, Classified, Classified...then there is your thread George. keeping the DFI name alive :D

great work with this board, keep it up :up:

Is DFI LanParty UT X58-T3eH8 worth the extra money, or does DFI LanParty DK X58-T3eH6 do the job?
Have read almost everything Eva2000 have written and the T3eH8 looks like a damn good mobo with lot of power.
So what do the XS-gang here say?
T3eH8 or T3eH6.............

UT X58 definitely better than DK X58 for high/extreme clocks due to pwm on UT X58 able to handle more apparently.

Thanks eva, i get my board today i hope=)
I love my Dfi X48, hope i love this to:D
And one thing more, Dfi is one of the few that understand that we need to use pci lanes to.
Almost every board you put 4870 in crossfire on, they block every lane:down:
