Im waiting for a 3845A935 w3520. Whats the best bios for xeons?
Hey guys. How do I add QPI voltage on this board?
I cant get this board stable with my I7 920 D0 for the life of me.
1.21 vcore (Proven stable at 1.2)
1.45 cpu vtt
1.08 nb voltage
1.65 dram voltage.
What else can I do?
Could my 32M superpi instabillity problem be related to my SSD or only SP1 ( since SP2 is'nt on danish yet ) Could it be a software issue?
it would help if you added more info.. im assuming 4ghz?Quote:

QPI = VTTQuote:

Looking good - yes you might need more vcore in hyper pi for 8x 32m, happened on both my 2x i7 920 3851A368 D0 need 0.032v more vcore than prime95/linx stable vcore. Much different to my 2x i7 920 3836A756 C0 or W3520 3845A935 D0 cpus.
probably the ioh/ich and ioh analogue combined with higher vcore helped :)

nice work cheapseats... another tweaking master joins the thread :D
100 pass linx @DDR3-2000Mhz 7-7-6-x with trfc 60 :cool:
Isn't that crazy that only around 70C @ 1.32v on AIR :D
Not really both my i7 920 3836A756 C0 with TRUE120 4Ghz at 1.328v can do with 70-75C load temps with 26-30C ambients :) my i7 920 3851A368 D0 on water around 62-67C in 26C ambients :)Quote:

I have one of these mobos. I have not tweaked the bios yet. Running it at 175x91 with a 920 C0 chip. I need to speed it up or see about dropping the voltage on the cpu.
PRJ
Nice to see you able to get HyperPi to run. It's normally my first sop for stability testing once in Windows on the i7. It's quick and gets you at least 80% towards full stability.
@ eva2000
Well, thanks for your tips on where to go
Now I can start optimizing, now that i finally have a stable setup :)
Would you be satisfied with these Voltages for 24/7 use?
@ Cheapseats
Set VR Current Limit Max: Enabled Does this not need to be disabled when OC..?
yes very good for 24/7 - i use 19x211bclk 844mhz 6-7-6-x 24/7 hehe
Set VR Current limit max = enabled for best clocks - tip #4 http://i4memory.com/102537-post3.html to disable TDC/TDP protection :)
PRJ, what kind of block are you using on your 'Northbridge'? Looks clean! :)
I finally got to building the w3520 system yesterday but couldn't even get win7 to install....it kept on freezing during the percentage part...sometimes it would make it to 30% and othertimes not even 1 percent....I had everything in the BIOS set to defaults and made no changes...I put my Areca 1231ML on the 2nd PCI-E 16x slot (where your 2nd SLI or crossfire videocard would normally go) and my PCI-E X-Fi on the x16 yellow slot which is supposed to run at 8x....I didn't update the BIOS yet and am thinking that is the problem, but could anyone help me figure this out?
Almost forgot - I'm running a single 4870x2 videocard.
It's a MIPS, but dont buy the mosfets cooler, a mis-installation just costed me a new motherboard.Quote:

Edit: It would be also interesting to know what mounting kit exactly it was that you used. The one supplied with the blocks or self-brewed?
Hey guys,
seems I "fixed" my issue from earlier. After days of testing I finally decided that the mobo doesn't like the ram I was using (2 kits of Gskill F3-12800CL8T-6GBPI)
The DFI seems really picky about ICs, so just a heads-up for anyone looking to buy that ram for the DFI.. don't. It really only likes HCF0 and MNH-E.
memory tips http://i4memory.com/102537-post3.html - different ic types have varying cpu vtt to vdimm optimal differential voltages as well as dram / pwm switch values. Just a matter of finding which values are for which memory ics and cpus. Micron ics like decrease 15% while samsung hcf0 and elpida like nominal or increase 15%. Of course my experiences might not translate the same for you.Quote:
