Just wondering how they are holding up over time. I have a quad Penryn and wonder what sort of overclocks are generating premature failure or unreliability. I do understand Intel's position is to disclose the idea that risk essentially scales up whenever you are above the functional operational limit of their CPUs. And they suggest exceeding the maximum core voltage (1.45v w/ my QX9650) definitely amps up the risk of premature failure, unreliability, etc. So, do we have any estimates of realworld failure rates in penryns?Noel

Smoke'em if you got'em....... :(

I don't know if any source of data on Pen fail rates. Unless someone finds or knows of some raw data, my best advice would be to keep tabs on the various clocking forums around the net and that will give you maybe some general idea.It would be interesting to know, long-term, how the hi-gate transistors hold up to overclocks. This was a concern I remember, back from before the Penryns came out. Anyone hear anything new about that?

E8400 @ 4.0GHz and 1.46-1.48V on air for 1 year and still going :)If you want a more elaborate sampling of o/c's check out extremesystems.org.

Thanks for your testimony and comments folks. That is pretty good testimony. I am able to run at 4.1 at 1.406v on air (plus a/c cooling) and it all seems fine, but I'd hate to kill it too early. I usually run at default speeds just cuz I don't need the power for most everything.

1.4v is fine for a Pquad.. 1.42-1.45 is pushing it.. above that is on the clock

Ahh, he's back. Hi Nick. I should be good to go then. I installed Vista 64, and audio pops r gone now with drivers other than 169.12--yes! I have a 280GTX to play with so will see how that goes now. I am dual booting to Vista 64 using the BBS popup in the ASUS BIOS, and have made the volume Vista lives on invisible to XP, so should have resolved the restore point issue or whatever it was. I am keeping Vista as lean as possible--only FSX and it's addons, that's it. No antivirus, no nuttin'!Nick, does your tweak guide for sys set up apply to Vista 64?
