max Vcore on air

[c00z]

I am currently running 2300mhz 10.5 * 219 and was wondering what is the highest i could go on the voltage. At Vcore 1.85V but it is undervolting a bit as all abit nf7-s board do. Heat isnt a issue current idle is 43C and load under 50C

What are you guys running to get to 2400mhz?

i would put that cpu at 1.9vcore as long as the cpu says under 70C your good.

If you can get temps lower...then pushin 2V shouldn't be a problem.

Will not at 1.9V-2.0V EM(electomagnetic migration) begin to occur, the shit that was causing the NSD(northwood sudden death) happen? I thought that once you reached that high of a voltage you would be degredating the life of the processor. I only need it to last approx 2 years but would it last that at such high voltages

Also, i dont think i can drop the temps any more, I am using artic Silver 5, the huge zalman all copper on full speed, and 120mm exhaust and 120mm intake, thus I think the temps are as low as they go. Sandra reports 93Watts coming from the processor and thus I think that it may not even be able to handle much over 100W full load without getting too hot

According to AMD..their XPs can take +0.5v

1.65 + 0.5 = 2.15v

Anyone currently running above 1.9V on air? if so what are you doing to keep your temps down since you are near 100W of heat generation off of the cpu die

does anybody know if 2.3v is a safe core voltage on an XP 2800+?(trying to hit 2.6ghz and keep it stable)

 

[c00z]

I would think that you would get degredation of the core, the switching gates get fuckign when you up the voltage too much they dont respond well to that high of a voltage for prolonged periods of time. Read into what the voltage does to the cpu with regards to the switching of the gates

ps what temps are u running at and what voltage are you at now to get that high?

dont take this the wrong way, but judging by your post and sig I would say you are a nutcase. 2.3v will ruin a processor from what I have heard.

c00z what kinda processor your running?
eraser_16 it is safe if you stay under 70c..

my 2400 hit 2.6ghz with 2.2v and it had stock cooling with a tonado funnel in front. it stayed at 58c

 

[kleptophobiac]

I ran 2.3v into my barton... didn't seem to do anything for me. Just raised temps, warmed up my room, and got unstable. I backed down to 1.9v and all was well.

I'm running water.

don't take this the wrong way, but i think you're wrong. i'm staying under 50c even at full load at 2.5ghz. i think i can hit 2.6 and keep it stable.

i'm running about 45-46c at idle and about 50c at full load. i'm running it at 2.5ghz with 2.0v right now, but when i tried 2.6ghz, i was using 2.2ghz.

I wasnt doubting that your processor is at a reasonable temperature, but that isnt to say that the voltage wont hurt your processor. The damage from having too high of a voltage isnt heat, its EM as said before. It's up to you, of course.

 

[eraser_16]

you may be right, i'll probably just leave it alone. 2.5ghz is pretty good.
