Man I wish mine ran that cool at 1.45v. That is what mine is at 1.35v prime95. I have an excellent overclocker but on the flip side runs a little hotter than the norm.
This classified board is finicky and I am not used to it yet, I came from a Gigabyte. I am slowly get a little better with it...:up:

For comparison, whatever the 3850 did, the 3851 needed 0.1V more to do.
So maybe the batches are starting to degrade again, or its just that the first batches were 975 binned that were re-labeled to 920 due to lack of production unit and the new batches are lowered binned cpus.
Time will tell I guess.
Anyway, I Just got a D0 3850A795 and Bloodrage GTI, together with Kingston T1 (Elpidia Hyper chips), they make some very nice results.
http://img29.imageshack.us/img29/1420/32m7m52s.jpg
The Bloodrage is a very nice board, too bad it stopped at the famous 222 "wall".
Damn thats very nice OC, what sort of temp you getting ?
Didn't really looked at the temps much, I need to make a serious run with LinX and see.
With my current WC setup I should probably be going at around 75c-80c degrees.
Still very very nice, what you gonna be running at for 24/7 ?Quote:

how do you check the IOH temperature? the MB temp under everest?Quote:

I think 4.51Ghz with HT enable is getting close to the limit of this chip for 24/7 with water. :yepp:
It's in the BIOS under Hardware Monitor. This is on Eclipse Plus so yours may be a little different.Quote:

Yep, this one came from pao_revolt and is Batch# 3849B203. I ordered my Xeon yesterday from NewEgg.

Being a newbie somewhat I am still tweaking to get stable OC state. So I will post back as soon as I am able to obtain one. For now, I'm having stability issue, which may not indicate a bad chip, probably just something I'm not doing correctly.Quote:

My Xeon W3520 is the Batch # 3848A352. I run 50nm Elpida Hypers. I am having excellent luck with it. Seems the Uncore is stable up to about 4200MHz or so as well. Very good batch IMO.Quote:

If I up my PCI-E frequency to 105 or 110, I can get my D0 to POST at 225 blck, but it won't boot any OS. When it finishes POSTing and it tries to go the next step (booting from an OS), the screen just becomes blank, nothing on the screen. I haven't tried anything higher than 225, so I don't know if it would work or not. Gotta give it a shot.
Nice clocks on that W3520 ... 4.8 at 1.28 Vcore :eek:Quote:

No its the 3848A352, I started out on water to get used to the motherboard and all and see how far I could push it, then I put it on the OCZ Cryo Z single stage. Next will be LN2 or DICE, I am having to give it 1.425 volts to make it through the cpu test in 06 @ 4.9Ghz.Quote:

I don't understand why using two kits of tri-channel memory, my Corsair is able to boot and run just fine at 9-9-9-24 2N while my OCZ Platinum just simply cannot do it. It can't boot. Both are DDR3-1600Mhz speed with the OCZ's timing of 7-7-7-24 (1.65V) and Corsair's timing of 9-9-9-24 (1.65V). On both kits, I can POST and run fine at 21x200. As soon as I up the bclk to 205, the OCZ can POST, but can't load the OS. The Corsair can that just fine. I've tried (on the OCZ) both manual timing and auto timing, no luck, the PC crashes every single time. The Corsair works just fine.
Getting up there a little higher... :D

Hello
Can you tell me if it's a good produc for OC ?
Tanks
Generally not , many do 4.0GHz HT on more than 1.2v. But angelreaper got a nice one:up:. But they do run a bit cooler :up:Quote:

The Corsair works just fine using this setting, but the OCZ craps out each time even though it has the better timing than the Corsair. Time for RMA?
BTW, what does Uncore freq do anyway?
On the 222+ blck, I can run stable at 16x225 (3.6Ghz) but any higher than that the PC craps out. Vcore is all the way up to 1.35v something. Is this D0 a bad overclocker or is it just something I'm not doing correctly here?
IIRC you are using a MSI board correct? Are you running a multi video card setup? I would bump the IOH Voltage up to 1.35v to see if that adds any stability. On both my EX58 and Classified board I need around 1.3v-1.35v for any Bclock above 210. The suggestion to bump up the vDimm and VTT sound good to me as well.Quote:

want to see the fastest i7 920 on the planet courtesy of Windows 7 and CPUZ flakiness during Hyper Pi 8x 32M Pi test ? How about 12200Mhz - 61x200bclk LOL
http://fileshosts.com/intel/DFI/DFI_...m_8x_12200.png
Update: interesting the vcore required for HyperPi 8x 32M PI test might be just for that, as I started testing Prime95 small FFTs 1hr stable at 20x200 = 4000Mhz at 1.312v and Prime95 Blend custom 5.4GB test at same 1.312v and it's running without problems. So HyperPi 8x32M Pi test might come down to memory/voltage related settings. Will try lower vcore after the custom Blend test and then LinX.
You guys should try HyperPi v0.99b 8x 32M pi test to compare against your prime95/linx runs ;)
HyperPi v0.99v download link http://nx.i4memory.com/hyperpi/hyper_pi_0.99b.zip

Your validation is positively shocking, especially considerng how you achieved it, hope to see more numbers in the future. And thanks for the tips, I'll try them out.
Just got my 920 d0, did a quick 06 run at 4.2ghz at 1.3v (Just a wild stab, no idea what it actually needs). My batch is 3849B028, wonder if its any good or not as I haven't seen anybody else with this stepping. Will get to real testing on wednesday, after my finals are over.
Where did you order yours? Seems like batch B0?? OCs the best out of the bunch.Quote:

t is the 4.305Ghz) that is more beneficial, correct?
What would you recommend for air overclocking (TRUE) on a medium budget, Q9650 or 920 D0? I do not wish to spend much money on motherboards, it would be from the Gigabyte UD3 or UD4 series for both CPUs. I do not wish to bench them, I just need a 24/7 stable system for rendering and 3D animation. Is it possible to run these guys over in the 4.2-4.5 range for stability on air, or it's about the 4.0 range, which you might recommend.
Your Ram/uncore/qpi speed will suffer a little bit, but cpu speed trumps all as you'll have more bandwidth than you'll actually need.Quote:
