Thanks

Did you stress-test it thoroughly? I had mine matched with a 680i board, and couldn't get it past 3.8. Then, while waiting on an RMA replacement for the motherboard, I picked up a 780i and couldn't help but get the E8600 E0. I'm waiting to finish building another machine with the 680i and the E8400 -- not expecting to over-clock as far.

The retail-box maximum-voltage spec on both these processors (E8400 and E8600) is 1.25V. If you have it set in the range you describe, the vDroop and vOffset will probably cause it to drop within 0.02 to 0.05V of that spec. My E8600 (@ 4.15Ghz) is set to 1.300V, and reads out a load voltage of 1.25 to 1.26V.

Figure that the percentage corresponding to the overages I cited is between 1 and 3%. You shouldn't have any trouble at all.

But I would recommend putting it through its paces with the multi-core version of PRIME95 for 8 hours or more (I ran it for 16 hours), and then give it a 2-hour workout with IntelBurnTest. And for plain-old "better cooling" I'd get an aftermarket cooler like the TRUE or Noctua NH-U12P, unless you're watercooling the sucker.

If it passes the stress-testing I've described, you shouldn't need to tweak it much more, and -- yeah -- 24/7.

>>>S-spec- SLB9J

An S-Spec with a 9 in it is an E0.

DaveR...

Thx... "EO" stepping.... tougher to get higher OC?

I just received the Xigmatek S1283 HSF also. I really don't look forward to installing that...MB removal, backplate etc...first time I'll be doing this....

Sweet. That's a nice setup.

Asus P5B, 4gb Cas4 XMS2, E0 E8400, and Xigmatek S1283. I think you're friggin' set, bro. I would happily take that to 4.3ghz+

Jared...

4.3 ... YIKES...

That's going to be some serious "FPS" in COD4 and COD WaW... even running the game at 1600x1200.... then my bottleneck will be the video card....just now need to get the GTX260!

CPU-Z also shows the stepping.

Word is that E0 flies higher.

Bet it's not stable (as in at least 12 hours of Prime95). On this chip it's stable enough unloaded to run Vista and not crash at lower V. But that's not good enough.
