I'm just wondering if there has been any reports on P4 C's dieing due to higher vcores.
I remember hearing less and less about P4's dieing because of too much voltage (anything above 1.7v) ever since the beginning of the P4 B's. Maybe the new P4 C's are more tolerant to say 1.8v???
If anyone is filthy rich, please support the hardware community by purchsing a dozen or so P4 C's and running them at 1.65v, 1.7v, 1.75v.... 1.9v and see if they burn out :D
(speaking from personal experience only...)
I've had my P4 2.6C running anywhere from 1.6V to 1.8V lately (1.8V usually for benching only...)
I've primed it at 1.7 - 1.75V a few times overnight, no signs of SNDS so far! /Touch wood... ;) I've had the chip for around a month or so.
I should mention that LOAD Vcore is almost 0.1V below idle Vcore on my P4P800 Deluxe. With 1.75V in BIOS I'll only be doing around ~1.66 - 1.67V at full load.
I would still be hesitant to put 1.8V through my CPU though! I ain't exactly filthy rich! :p
I wouldn't really bother anyway, because the extra voltage don't seem to help the overclock of P4-Cs much at all.
For example, I can get 3.3GHz with stock Vcore, 3.4GHz with 1.6V and a whopping 1.8V for 3.5GHz...
Not worth it for that last 100MHz IMHO...
Very true...
i can do 1.525vcore (defualt) and overclock stable to 3.12ghz, but its not stable at 3.24ghz with even 1.75vcore going through it.. and SNDS has it happend to any p4C at all yet?
I pushed 1.85v through my P4C 2.8 without a problem (1.90v in BIOS, Actual 1.85v) I also pushed 1.85v through quite a few P4 chips, Some 200Mhz, 133Mhz and 100Mhz FSB processors... Not a single death! :)
But I bet you didn't leave them running like that for months..;) :p
Nope... But I know a quite a few people who run 1.70-1.75 24/7 for over a year now without a death in the family... So it all depends on the cooling, the chip and how hard you stress it I guess... Shrug
Or... it depends on the chip most likely.;)
