DFI UT X58-T3EH8 continued - Part 2

[eva2000]

Did you use C1E ? if so than yes low idle vcore with vcore jumping higher when cpu loaded is normal

Some High Uncore frequency testing http://i4memory.com/f83/i7-x58-mem-f...equency-18156/

My Dfi UT T3H8 will be here Thursday.
First I had Asus P6T, TDP limit kept OC down. Then Gigabyte UD5 great 24/7 overclock, 4.6 Ghz, but had problems with high B clock + high ram frequencies. Then Evga Classified, think I just recieved a dud board, and New egg RMA ed it, but since no replacement in stock. lol. So hopefully the DFI will be a good compromise of all my previous boards.

Bleargh, it sucks when hardware decides to die just when you're starting to make some progress. A word of warning from me: be careful with your Elpida Hyper based memory. It seems like these IC's are accidents waiting to happen! I had a 0.01v overvolt on mine when one stick died, and googling the problem reveals many cases of dead Elpida Hyper memory.

What ram would you recommend for this board?

[Dami3n]

What ram would you recommend for this board?

Gskill trident 2000 cl9, cheap and great ocers

[ChrisB17]

Wow very nice ram. What would you recommend sub $100.00 range? If thats even possible.

[Dami3n]

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. (2nd link first post, in post #3 http://i4memory.com/f55/intel-core-i...ide-x58-13051/)

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

Nothing, im stuck in 3,8. I try almost every vtt/vcpu combination, even with ram at x6 instead x8, with more voltage in nb, but my cpu don´t like 4ghzs. Im limited by my cpu temps, that are insanely high for my cooling, reaching >84º easily in linx

Maybe its time to try a 920 D0 or one of those great w3520

Wow very nice ram. What would you recommend sub $100.00 range? If thats even possible.

You can try gskill trident 1866 cl9 or pi white 1600 cl8.

[ci2kla]

Gskill trident 2000 cl9, cheap and great ocers

I'll say perfect storm CL9 instead of trident

[eva2000]

Loving this DFI UT X58-T3EH8 + W3520 + Corsair Dominator GT 2000C7 combination even more. How's Uncore frequency @4600Mhz with QPI frequency @4140Mhz with 230bclk straight boot from bios for Super Pi 32M and 3dmark06 on water cooled cpu!

• Uncore Frequency = 4600Mhz
• QPI Frequency = 4140Mhz

Super Pi 32M


Everest Bandwidth


3dmark06 single HD4870x2 stock


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

edit: W3520 @4877Mhz H20 http://www.xtremesystems.org/forums/...d.php?t=226137

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

[ChrisB17]

After countless nights of researching motherboards I finally ordered this one. I am excited lol.

What bios is recommended with a I7 920 D0? Can you post links to the one recommend? thanks.

[Russ_64]

@eva2000 - Wow, that's a 83% OC - nice one

05-08 has just been released as "official BIOS", and it is working fine with my w3520. I believe this would be your best bet for a i7 D0 too. download

Awesome. Thanks

[ChrisB17]

Sorry for the double post. But is this board have a B3 X58 chipset?

[cstkl1]

Main settings and flow of clocking

1)prime 95 large fft custom 5.4gb 3 hours, vcore 1.2625v , vdimm 1.58v dq vref +1.5%, set bclk 200 bootup bclk 185,vtt 1.37v set
error in linx second run

2)50 linx 5.4gb max - vdimm 1.6 dqvref -0.00%
failed in 55th run

3)100 linx 5.4gb max - vtt 1.39
but failed in prime blend custom 5.4gb in 4 hours

4)8 hours prime blend custom 5.4gb - vcore 1.275v set,
but failed in 9 hours one thread error

5)12 hours prime blend custom 5.4gb and 150 runs of linx -vtt/dram pwm frequency to decrease 15%
perfect

@eva2000 - Wow, that's a 83% OC - nice one

thanks trying for 4.8ghz 32m this weekend with cooler ambient weather forecasted

nice clocks on that i7 920 d0 - what batch is your cpu ? another week 45/46 ? 3845/3846 ?

nah no manufacturer has B3 revision out yet AFAIK

Wow Kavin alot of work done there!!

Who Know why my UT x58 alway shut down
power on run prime 4.2 g 7 min.. error

restart run prime 4.2 g 10 min.. error

then power on alway shutdown
again power on shutdown ...

i sleep

nextday
power on run prime 4.2 g 7 min.. error

restart run prime 4.2 g 10 min.. error

then power on it alway shutdown
again power on shutdown ...

my cpu temp not over 70C
nb 38c

have you disabled all current and thermal over protections ? tip #4 at http://i4memory.com/102537-post3.html (worthy link to bookmark and read)

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



Uncore frequency = 4707.8Mhz





Uncore frequency = 4760.2Mhz

They are starting to show up on some boards now. But, they do not make any difference in clocking, why this rumor continues to live on is beyond me.

[eva2000]

Hey Gary

Yeah new Asus super work station model ??? No diff in oc'ing ? like Intel says D0 make no difference over C0 ?

[Mafio]

eva, your xeon is really awesome

it need cold

That one and a couple of others, which is why I know Intel and the motherboard guys were right about B3. Actually Intel was emphatic that D0 would make a big change in clocking but the B3 stepping on the X58 was to address several PCIe power state changes and a couple of QPI errors, it was never about performance. I stated that a few months back but what the hell do I know.

[eva2000]

Unfortunately no such cooling available to me as yet. But I'll still push in on water cooling - weekend night time forecasts very nice cold temps - going for 4800+mhz 32m pi

qpi errors - maybe fixes allow high QPI frequency head room/bclk hence higher potential clocks ??? We can always hope
