The OP is up to date.
Good job everyone!

Any chance you can crop your posted image with your cute kitty so it's not so wide? Stretches the page's width quite some and a bit over the top.

My turn, finished to build & test new christmas rig:
i7 920 D0 at 4.5GHz (HT Off) giving 66 GFlops with 1.368v using only one internal triple rad with 3 fans to water cool both the cpu and an overclocked ATI 5870.

P6T Deluxe v2 board rev:1.02g chipset X58 rev:B03 crossflashed with 'no-throttle' 0006 Bios (more hardware in sig).

Screenshot and some Bios data that can help others:
---------------------------------------------------
CPU Ratio: 21 - BCLK: 215 - PCIE: 100 - DRAM Fr: 1723MHz - UCLK Fr: 3663MHz - QPI Link: 7759MT/s

[zalbard]

Very nice and detailed info, thanks!

[cky2k6]

This was in my htpc, I slapped a true on it, and it turned out well, I'd say. It loads at 1.344 most of the time, not 1.328v, and it hates llc.

[Boyu]

may i joint, thx

Watercooled, HT ON

[zalbard]

may i joint, thx

Sure, welcome.

And good job everyone!

[lowfat]

Cooled w/ a single stage phase change.
4811MHz w/ HT on.

[OC Nub]

First try using 4 threads on the 870. Will try and lower vcore.


Edit: another run using more mem and less vcore.

1.408v Vcore, 1.30VTT, 1.640v DRam, 1.80v PLL, 1.080v PCH, Gigabyte P55A UD6.

[ToxicWk]

Can I join? Done with a Mugen II and Ceramique with 27 C ambient .Motherboard is p5e

[zalbard]

Updated, and welcome!

WOW, great job with the e8600 Jor.

That`s pretty nice

[OC Nub]

Newer batch i7 920.

[zsamz_]

Newer batch i7 920

lots of juice but you got there

[OC Nub]

lots of juice but you got there

Yeah it isn't a golden chip but I am happy with the temps. Its a newer batch#3945A936. I am happy with it, I hope to do some nice 3Dbenches with this new rig. Vcore is high but 4500mhz is 4500mhz, and Im having fun.

[ChaosAD]

OC Nub what is your cooling and what is the ambient temp to get 75C under load at 4.5Ghz/1.48v?

gettin to 4.5 is

I am using the XSPC rx360, mcp655, apogee XT block, and an ek multioption res150, in my avatar its hard to see buy there is a window unit AC blowing at the rad.

[andressergio]

Newer batch i7 920.

Congrats friend you did it !!!

Cheers

[OC Nub]

Thank you Sergio.

Does anyone have any experience with Core i7 920 D0 batch 3941B138 CPUs?

Try asking here.

[CryptiK]

Nice work guys.

Just a reminder to please put your overclocks into the Xtremesystems database I made (make sure you show stability test in SS) - found Here

Add your OC details to the form, then click submit and the database will automatically update with your results. There is a link to the database in the thread I linked you to and
you can download it yourself in various formats as you wish.

According to my 4.4Ghz runs i think that i ll need about 1.55v to run 4.5Ghz HT on 20 Linx runs with temps around 90C. Do you think its safe for 20 runs. I would be able to pass with HT off with less vcore but i consider it cheating
