The Official Extreme Edition Overclocking Thread

[[KoG]^weaZel]

Pentium Extreme Edition 840 at 3.7 ghz Prime95 x4 stable for 24 hours (ok well not 24 hours but 23 hours and 55 minutes) with DDR833. The vcore was set to 1.40v in bios but would droop to 1.30-1.33 under 100% load. Will post screenie when I get home.

Parts used:
-Motherboard- Asus P5WD2 Premium
-PSU- PC Power and Cooling 510 SLI
-Cooling- Swiftech MCW-6000, Corsair COOL northbridge, 2-Koolance VID-NV2-LO6, Swiftech MCP-655, BIX III and a Typhoon Dual 5 1/4 reservoir.
-Memory- Corsair XMS2 8000UL 2x512 at DDR833 4-2-3-9 2.1v

this is a real crunching monster for D2OL running four "nodes" over double the output of my 3.4EE. Name on D2OL is weazel.

No overclocking picture, but some special P4 EE ES . It´s a 3.73 EE with only 1MB of L2 cache. I don´t know why cpu-z says it´s an nocona core.

But 1MB L2 is true, has same serial as 3.73 EE, only 1M and 2M is different printed on the HS.

I also have a 3.2 ee. Mine is only stable up to 215 fsb I have good air cooling. What temps do you have to run to get it up to 4ghz? On your ddr booster you can check to see what your bios says the voltage is. I have an Antec TP 550.

iam using a ocz powerstream 520ADj.. topping out your power @ 600w what!! how do you know that? many harddrives?

16floz470ml iam am ideling in about -25c on the cpu @ 1.6v.
Do you have the stock cpu cooling faan? i think you can hit more!
what is your temps and what volt is your cpu at?
