Where did you get your i7 920, what retailer?

Is Box cpu.

[Lukee]

sick man, could you post your mobo voltages?

+1 I'd like to see that as well.

[Lukee]

V.core: 1.240v on bios - 1.20v on Windows.
Cpu pll: 1.84v;
Qpi/Vtt: 1.28v
Multi: x19;
BCLK: 211;
QPI Link: x36;
Dram: 1688Mhz;
Vdim: 1.62v;
Loadline: on;
Uncore: x16;
Memory: 8x;
Turbo: OFF;
Pcie: 101;
Performance: Turbo.

Thanks..

One question.

BCLK - 211 What voltage do you have to raise to attain this number? I read that you had to raise vtt. The highest BCLK I was able to attain was 205-207 and that is with 1.35 vtt(roughly).

[denden]

my 211 bclk could also be acheived with vcore 1.312v HT disabled.

Thanks..

[dj883u2]

The cpu is stable at 4010Mhz with 1.20v.



Very good!

[herderien]

what about small fft's ?

I manually set by bios Qpi/Vtt at 1.28v. I have no problems of stability.

Those C0/C1 chips are bad to the bone... That guy is priming at 4.0Ghz with HT at 1.2 that's awesome haven't seen anything like that before...

Knowing batch number and rev is absolultley worthless if you don't know where these C0/C1 chips are sold. Only dj883u2 knows, and he ain't talkin'.

Metroid has a C0/C1 as well..

I am having problems tranferring files on 64bit Vista it's taking like 1 hour and 15 minutes to transfer 35.0GB of music anyone known why that would be??? Am I doing something wrong I am using WD Velicoraptor for my operating system and tranferring files between 2 Seagate 1TB drives internal..

My 940 is C0/C1. From NewEgg.

Man, glad u posted that. I have the same problem as you do.
Very slow transfer... Reinstalled windows/drivers etc but still same problem.
No idea what else to check.

Try the new Intel inf utility ver. 9.1.0.1007
Use the -OVERALL command. I have fast transfers.

[sonofander]

What does this inf utility do?

[Ace-a-Rue]

The cpu is stable at 4010Mhz with 1.20v.



Very good!

you are a VERY lucky guy for having such a sweet chip to do that for SOOOOO less vcore!

do you have SP1 installed?

have you tried to disable "Ready Boost" to see if that helps?

[Ace-a-Rue]

it updates the intel drivers for the OS.

So I'm not far away from you Joking

Voltage Bios: 1.27,5V Windows: 1.27,5V, no Voltage drop right here

I still need to make more tests,

Thanks for the ups

I have a C0/C1 as well, hopefully going to have it under water tomorrow. Did I get lucky getting 1 of these? Mine came from ebuyer.com on launch day incase any UK guys are interested.

[Hornet331]

damn here goes the batch lottery again... reminds me of the good old E6600 days... mine was from a good batch but it still sucked.

hope this time i get a decent chip.

[dinos22]

The Batch is: 3837B080

interesting

[Metroid]

interesting

My Batch is: 3836A867

An update: As the research progresses. I discovered that with Hyper-Threading on, it requires 3 to 5V more to be stable. That is, going 4 physical cores to 8 logical cores.

[Viss]

i920 3838A554 here but it needs at least 1.325v for 4ghz prime & HT it seems.

[Blacklash]

I've only got 3.83GHz here and I am on air cooling. Still I'm happy because it's much faster than my Q6600. Also I've finally got SLi on an Intel platform with massive bandwidth to boot.

hmm, so its the B batch again.

What does this inf utility do?

You have not installed it? The older ver. is on the P6T CD for the x58.

You want to use the -OVERALL command found in the readme.txt

-OVERALL
Updates ALL INF drivers on all available devices
even if third party drivers are currently installed.
This flag works in Interactive Mode only.

I created a directory called Intel. I placed the update utility in there. And created a shortcut. In my case C:\Intel\INF_allOS_9.1.0.1007_PV.exe -OVERALL



look, Intel uses 9.1.0.1007. Read your MB pdf.

You can OC all you want. The OS set-up is just as important for performance.
