DFI UT X58-T3EH8 continued - Part 2

[eva2000]

Why a new thread??

BTW,

founded this:

It shows how DK (but I think also UT and JR can handle) manage voltage regulation system.
Sort of advanced Smart Guardian...

but I can't found...

U guys know something about that??

wow first time seeing such an app.. apparently it's something reserved for new DFI boards and ABS2 function - but not sure. Will ask DFI.

I see you guys are talking about GPU, and I've been trying to get the PCIe-frequency over 100 with a GTX 295.

I could never boot with PCIe>100 with my good old CO, but now (with w3520) i can get into W7 with PCIe=105. This requires almost no tweaks and my desktop-applications seams to be running fine with no problems, but my display freezes (and sound loops) a few minutes into Crysis (even with GPU down clocked to stock). I have tried to give a bit more juice to SB by raising the following Voltage:

IOH/ICH 1.1V Voltage: 1.21v
IOH Analog Voltage: 1.20v
ICH 1.5 Voltage: 1.7v

but the problem remains. I hear that this can be a GTX 295/SLI-issue. Any advise what else could help to stabilize high PCIe-frequencies on a multi-GPU/SLI-setup?

never used GTX 280/285/295 so not sure. With my HD4870x2 x2 CF can can bench up to 110-115mhz PCI-E without problems but it varied between cpu to cpu for my 4x i7 920 c0/d0 and w3520. Maybe look at your lowgap value ? for 2x GTX 295 SLI need at least 2048. If you have other PCI-E/PCI devices i.e. sound card might need lowgap between 2560 and 3072

Can't seem to get over 200BCLK stable, I have bolded all items I have changed. I noticed you have been using AUTO for your CPU Vcore and using special add to increase the voltages. Are there any advantages to doing this over just increasing the VCore manually?

no advantage i know of, only used it as my w3520 cpu has a turbo 21x multi issue when using windows 7 OS only. WinXP/Vista doesn't have this issue which forces 12x multi for cpu in turbo mode on win7 (see last link in first post in this thread). This auto vid etc is work around for this until DFI releases a new bios (which they're working on).

bclk will vary from cpu to cpu as to what voltages are needed - mainly for me it comes down to and centered around cpu vtt voltage. Get cpu vtt voltage right and subsequent vdimm balance within 0.5v of cpu vtt, and rest usually fall in place. Although, higher your push memory with bclk, more likely need ioh/ich voltage to help too. (again mentioned in 3rd link in first post in this thread http://i4memory.com/f80/i7-920-d0-df...ability-16617/ (everything you ever you need are in first post's links )

Again, I am using the latest beta bios from DFI 0508

I have an i7 920 D0 (SLBEJ) cooled using the Noctua. I am using 1 x 2gb stick of OCZ animal placed at dimm slot 2. I should receive my own 6gb kit 3x2gb on Tuesday.

RAM - OCZ3P1333LVA6GK
Cooler - Noctua NH-U12p

for non-elpida modules such as micron based OCZ animal try 2/17 or 2/27 bios instead

Oh so close.

4993.95 MHz

wow nicely done

Maybe i found the reason for burning my motherboard, the Mips cooler on south bridge do not cool the circled area.

Does anybody know what this area is?

Since I found the reason for my dead card, I'll stay with DFI and buy another, this time just adding a licquid cooler to the original DFI heatpipe assembly.

(Upload of picktures does'nt seem to work for me..?)

ah forgot you're using pre-retail sample DFI UT X58 from that photo it doesn't have the DMM read points etc. New retail board probably better

Anybody been able to make Quad SLI 2x295 and 12gb of memory work on this board?

first link in first post - tip #20 http://i4memory.com/102537-post3.html make sure lowgap value is set correctly and then I'd test with 6GB first to figure out your system config's optimal voltages for stability, then test 12GB (2nd link in first post http://i4memory.com/f55/intel-core-i...ide-x58-13051/ - testing memory behaviour and performance and finding optimal cpu vtt/vdimm voltages first will allow everything else to fall in place smoothly ) .

Thanks for all your great work here and at i4memory eva. It's great to have the benefit of your knowledge and experience.

You're welcome

Now that i have more time, im trying to get 4ghzs for my 920, but without success
It´s strange. No problem with 3,8 HT ON at 1,248v(1,26v in bios), but when i tried 200x20 or 211x19, even without HT, prime freezes in a 10-15seg. No matter what i try. I can reach windows with the same config for 3,8(1,26 vcore/124vtt), but even with 1,37v vcore/vtt, prime always freezes at the same time.
Any idea/advice/tip?

As i mentioned every cpu is different (1st link in first post - tip #2 and #3 http://i4memory.com/102537-post3.html), each cpu will have optimal cpu vtt requirements for bclk scaling and remember as you increase cpu multiplier the same bclk which was stable on lower cpu multiplier, might need more cpu vtt on higher cpu multiplier.

i.e. 19x200bclk might be fine with 1.37v cpu vtt, but 20x200 bclk might need 1.39-1.47v cpu vtt, 21x200bclk might need 1.39-1.55v cpu vtt. All depends on your individual cpu. Also cpu vtt voltage needed will also depend on your uncore frequency. The higher QPI frequency the more cpu vtt volts is needed. The higher the uncore frequency more vdimm is needed.

For prime95, linx, hyperpi stability again mentioned in 3rd link in first post in this thread http://i4memory.com/f80/i7-920-d0-df...ability-16617/ (everything you ever you need are in first post's links
