Safe Vcore setting?

[quantumgroove]

I just overclocked my 2.53 Ghz p4 to 3.2 Ghz. The question i have is what is a safe Vcore setting for my prossesor. Right now it's at 1.6, is this safe? How high can you set the vcore on a P4?
Thanks for your help!

don't go over 1.7v actual....

How stable is it though. The 2.4b will boot at 3.2 but craps ot pretty quickly in Prime95, regardless of the voltage

It boots at fine at 3Ghz, i've also payed unreal 2003 on it for a while, run a bunch of system benchmarks on it, had 3dsmax render a bunch of frames on it. So i'm pretty sure it's stable but i'll run prime95 on it.
thanks for the advise though.

yes this new breed is nothing like the old Deschutes (!) that I spent tons of time tweaking, The fabulous Celeron 300 that overcloked to 450 without a hitch would lock up completely in Prime95 at 500mhz. The early PIIIs did that too.
These new P4s must have some kind of "fallback" mode to prevent crashing.

That is quite the assumption you made...It may be a c1 steppng chip and thus could be perfectly fine at that level....If it is a B0 stepping I would have to agree it may not be stable as that would have been one of the best I have ever seen for that chip.

You vcore sounds safe but I don't think you are giving us the true actual vcore. Don't give us the number you are settihng in the bios as that does not reflect true vcore...some mobos undervolt and overvolt, and you may be anywhere from 1.54v to 1.68v actual (taking in account some of the worst undervolters (abits, MSI, early Epox) and overvolters (Asus, Albatron)

Sorry, typo on my part, should have said "My 2.4b...", sorry. But yes it is a C1.
As I posted just above, these new chips are nothing like the old Deschutes that would just crash the system miserably when unstable in prime95.
I've just reencoded a full movie in Rempeg at 3 ghz and it didn't complain so it seems Prime95 has a lower tolerance than other programs.

3ghz is ok

 

[BeBumbleBe]

yes, but lI need to see what the result looks like, I suppose that the errors shown in Prim95 must pop up somewhere in Rempeg, it's just that it doesn't stop!

I've got an Asus P4PE motherboard. according to Asusprobe, the software for monitoring the bios i am at 1.648 volts.
The CPU is a B-0 stepping P4 @2.53Ghz overclocked currently to 3.01Ghz, my ram is running at around 412Mhz(i forget exactly) and it's set at the most aggressive timmings. I ran prime95 for 8 hours and it never crasher, it posted a 112 degrees Farenheit temp at full load and 102 F at iddle. So is this a safe overclock?

 

[BeBumbleBe]

These temps seem pretty reasonable. I'm surprised there isn't more of a difference between full and idle though.
Are you using the stock fan?

 

[quantumgroove]

actually when i wrote 112F i meant 121F and i'm using a Volcano 7+ with arctic silver 3. And i've got 6 case fans installed. It reached a temp of 121F after running prime95 for 6 hours.

 

[quantumgroove]

Furthermore i've got a Radeon 9700 pro thats has its engine clock set to 342.47Mhz and it's memory clock set to 329.68 mhz. With the CPU running at 3.01 Ghz and the cpu at it's most agresssive memory setting i got a 3d mark of 16,934. Is this reasonable for what i have my hardware set at?

 

[BeBumbleBe]

did you run comparisons between the stock fan and the Volcano 7+ with arctic silver?
