Core i7 920 rev D0 stepping 5 :)

[luie]

wish you well with the 4.4Ghz, .OSX.
good to see 1.2750 is a sweetspot. great reference point for the rest of us.

4.0ghz - 20 passes on LinX - stable on Air with Biostar TPower X58

[/QUOTE]

4.2Ghz seems to be the sweet spot for my CPU, can do that on 1.26v fully stable takes a big voltage jump for 4.3ghz as seen below.

Got some OCZ Blade 6GB (3x2GB) DDR3 PC3-16000C9 2000MHz arriving tommorow from Novatech, will see if that gives me more headroom.

Nice! Btw, do you have HT on or off?

on UD5
-1:3 + 1:4 tested, all options available
-Uncore 13 x, 16x, 17x tested, all available
-QPI same options as before only 36x (18x) tested

Sounds like your bios

I am happy to read that.
I will push Asus to work on it.
Competition is always helping us.

[Brama]

This is a kind of petition.

I am sure (I tested by myself) that Rampage II Extreme is not able to unlock:

- DRAM multipliers other than 1:3 and 1:4
- QPI transfer rate
- Uncore frequency

From other messages also P6T family has same locks.

A Gigabyte user assures HERE that in his motherboard above settings are all unlocked.


I hope that every overclocker that has a Xeon cpu will push Asus in any way to work on unlocking Xeon cpus.

Come on Asus, you can not be beaten by Gigabyte!

[mstp2009]

Is this a retail or ES Xeon?

The ES Xeons have the QPI and Uncore locked, it's not ASUS's fault for those.

It is a retail W3520 that on Gigabyte motherboards seems unlocked, as says FragMagnet some messages above (LINK).

Pretty sure it is their fault, unlocked on the gigabyte

[mstp2009]

Good to know.

I've used some ES chips on the P6T-D v1 and they were all locked, but they were locked on other boards as well.

Hello from Germany

I can by an D0 Batch 3847A821.
Google say nothing over this Batch. Packdate 04.08.09
Have you here any ideas ??

I would just go for it, you might get a better clocker than mine, who knows - I bought mine without checking on the web for results.

Nice! Btw, do you have HT on or off?

HT is on, hard to see but you can actually see if look closely on LinX it states 8 threads.

[drnip]

Here's what I got for my 2nd overclock on my i7. Still tryin to get use to this setup. I'm likin this CPU as it's all types of fun.

what are the rest of your voltages at?

[FragMagnet]

After working another 12 hr shift I decide to pop a window last night just to get a feel for this cpu. I limited the tests to 15 mins of prime95. I had the room at 17c ambient measured at the air intake. When adding a second fan to my TRUE I moved the H/S a bit disturbing the AS5 settling. The diff in my temps between cores went from 6c-9c so I need to reseat with a little more pressure. Thes are not fine tuned and volts can come down a bit yet anyway here's what I found out.

turn on HT


max 15 min prime stable


mobos bclck limit


needless to say I'm happy I have some good baselines and bios profiles, and the lower ambient really wasn't needed. I just realized that it was a 2 Ghz o-clock !!

[roller11]

Frag,
You may not realize it, but I think you just set a new record, at least for this forum. 4557 Mhz is the highest sustained prime run I've ever seen in all the
i7 920 threads. It's all the more impressive given your high temps. By that, I mean the higher the temps, the better the AC characteristics have to be.
Way to go, man!

[mk-ultra]

wow those D0 are very impressive....you guys convinced me

should i pay 377 of 920 or 400 for a W3520?
i mean is the 30 bucks worth it?

that's canadian money btw

[.OCX]

20 passes on LinX

Once I read this, I didn't even look at your settings or submissions for I already knew they were invalid. Run Prime95 Blend 30m - 1hour then resubmit. Try actually testing for VTT instead of just setting 1.35v thats WAY too high compared to respectable submissions.

GIGO: Garbage IN, Garbage OUT

[fallwind]

Get the 3520. I havn't heard of any CDN retailers shipping a 920 D0 yet and it will be a long time until you can be fairly certain to get one. Not many stores here will let you browse their stock either.

I got my 3520 today from Anitec and they still show stock, but I know it's 3 units max left. I'll be popping it into my DS4 tonight to see what it can D0!

[mk-ultra]

yeah the 3520 i checked is from anitec
or i was gonna order a 920 from overclockers.co.uk...a bit cheaper but i guess the custom fees with make it pretty even

i'l order it before they goes out of stock :P
also a bloodrage, and 6gb of G.SKILL PI Black 6GB

EDIT:
if they only had 3 in stock they only got 2 now

[drnip]

It is hot as all get out here but managed to boot at these speeds. Could prolly get the volts down some.

[ben805]

Was that directed at me? Its on water, but the room started out @ 19C ambient, 21C at the end of testing. My cooling goes, 355 pump + Xspc top-Feser 120.3 with Yate loon "m" with shrouds-heat killer 3.0 - Switech mcr320 with yate loon "m"

VERY NICE load temperature, looks like I'll have to consider moving my water cooling setup from the Opty rig over to the Core i7, these Core i7 are uber heat generator.

wtf is your problem? First off you're kidding about stability right, 20x linX will crush your cpu harder than 8 hours of prime especially blend I would hardly call 1.35v a high vtt either.

Stop spreading false information, and brush up on your i7 overclocking before you come into a thread like this acting like the mack daddy.

A "quick" test on a tad more Vcore than desired, but there's still quite a lot of headroom available...(and with HT as well, for later ...)

Last week, Dell.ca deals of the day had the i7 920 for $299.99 + tax = $338.98.
=( you might be lucky to see someone who bought them and trying to make a profit out of it (on redflagdeals or craigslist). As far as I know, all cpus Dell shipped out (I have two right now) were D0, batch 3844A717

[pcdoc1]

Hey ben...

I've been skeptical on the D0 hype as most of the 920 stuff has been sweet regardless of stepping...

Look forward to you firing one up...

May have to test a D0 for z and giggles.

VERY NICE load temperature, looks like I'll have to consider moving my water cooling setup from the Opty rig over to the Core i7, these Core i7 are uber heat generator.
