What is the max safe voltage for a P4 2.6C?

[Tavoc]

By safe I mean "will cause little to no long term damage."


Thanks

safe? as in actually safe forever?

1.55v max, just as intel suggests

 

[Tavoc]

Basically I mean where it wont burn out or be seriously damaged in about 3 years. I can do an overclock of 3.25ghz at 1.55v but I want to know how far it is safe to push the voltage. I know theres no absolute answer, but any personal experiences would be great.

Thanks

id say 1.55v.

Yes I know the only completely safe voltage is what they reccomend, but they obviously are going to be conservative with that number. I am looking for what experiences others have had with higher voltage P4Cs, any help would be appreciated. Has anyone been running their p4c with higher than default voltage since they installed it, and if so are there any negative side effects yet?

Thugsrook, do you have the voltage increased any on your 2.4b @ 3.5ghz, and if so how long have you been running it like that?

 

[Soulkeeper]

it would be about the same as the rest of the P4c procs
this question has need asked like twice a day for the past week i swear
hahaha

but anyways i wouldn't go over 1.65v
the lower the better like thugs says

Anything over 1.60v and you will be risking SDNS.

If it is a retail chip, you have a 3 year warranty.

it takes 1.65v (bios) to run 3.5ghz, but i have to admit that ive only been running it @ 3.4ghz default voltage for quite some time now.
the extra 100mhz just isnt worth all that heat pouring out of my case.

adding voltage isnt gonna get you very far and the performance difference is marginal at best.

P4 2.8c @ ????
Abit IC7 | KHX3000 | MCX4000 | BFG FX5900

Could you please fill in the @ ????
in your sig. It is driving me nuts. :evil:

dont get too excited John ~ it isnt impressive

Above 1.7V is really pushing it.
I'd try and keep it below about 1.65, or 1.6V (read in bios). My 2.6GHz needs around ~1.6V to reach 3.15GHz, but I've not thoroughly tested it yet.

The fact is there is no proof to date to prove this claim....

The northwood processor is still relatively new....What I can tell you is my 1.6a I sold to guy at AT is still running today almost 2 years into it at 1.71v....So until 3 years passes and we see massive deaths of northwoods since many have been ocing to voltages of p4a models up to 1.7v and the p4b model to around 1.65v levels...


My take on it is that a processor at default can according to operating hours listed by Intel which can be hard to compare since some ppl may not have pc on all the time...IMO I think a 5% oc in vcore may cut its life expectancy by 1/2, but for most ppl that is longer then their intended use....An oc of vcore by 10% will cut that time in another 1/2 or 1/4 of the full life expectancy.
Ofcourse none of this is scientific but either is anyone elses theories....


So in my opinion I would run no more then 1.6v actual and I believe the chip will last 3 years.....


I say get what you can....At 1.58v I still see positive gains scaling accordinly...no diminishing returns as Thugs suggest and the heat I can take....
