Warning signs of a dying P4?

[Elvis2]

I'm just curious being new to the Intel side of the street. What are, if any, the warning signs of a stressed out P4? Does running a constant higher fsb kill it even though temps remain reasonable (under 47C on a 2.53 for instance) or does increasing the vcore damage it quicker? Do you guys run @ c/c speeds all the time or just for benchin'?

The main killer of a P4 is voltage increases above 1.7v. And I'm referring to the actual voltage, not what you set in your BIOS. Some motherboards undervolt a hair (.01 volts) but sometimes the mobo will undervolt around 0.25 volts. At the very max I'd probably say around 1.725, but wait till Thugs and Davie, or Mech come into this thread for some more answers.

Thanks...yeah, those guys know their s***
Btw, what;s a good utility to monitor actual temps and voltages? Is Sandra pretty reliable?

Sandra is OK but still has issues with some chipsets and getting them in the right order...Use MBM (motherboard monitor) latest version...

HIgh vcore is the big killer. I mean if the chip can do 166fsb and not need a vcore boost then it is really no different from a stock chip. The high fsb is likley more dangerous to ones ram or mobo chipset then the CPU....Temps are also not as dangerous as INtel has the thermal protection that will throttle chip if it gets too hot...Stay below 60c under load and you likley will not encounter this...

My board undervolts .07v...so 1.5v default gets me 1.43-1.44v...just some basic info....Asus p4b533 mobos overvolt .08v so 1.5v default actually reads 1.58v at idle...beware of this...


The high vcore likely will over time start to damage the gates which has the process gets smaller (ie .13 micron) become more and more fragile. As gates go you start to get errors. Often these chips will not all out die on you. They start to give diminishing returns. IE...A chip that oc'd 1ghz may not be able to do much more then 500mhz, but then could stay there for a long time before nay further degradation.

Errors are like fatal or illegal program errors and winxp which is more sensitive at boot often may not get into it withous blue screening..

Thanks Duvie It's info like that made me become a member

Reason I asked is because I have a b0 stepped 2.53 @ 2.94 (155x19) on stock voltage and was wondering if I might be causing some damage. (Man, I luv this 8INXP )

v-core is what will kill your chip ~ not heat or clock speed.
keep it under 1.7v as seen in windows during idle.

we run these speeds 24/7

Yeah, ASUS is really quite heavy-handed with their overvolting. My friend's P4 2.4B (1.50V) runs at 1.58 at stock setting in the BIOS on a P4PE. More of the same with a C1 P4 2.4B (1.525V stock); it goes at 1.58-1.60V!
