45nm core volt max

Hawky89 · 3 Mar 2008 at 15:23

i have an E8400 and im starting to overclock it, i was just wondering what the max voltage that should be put through a 45nm chip? my stock voltage is at 1.192v

And another question, if you overclock but get a decent cooler that keeps the temps down, the chip should last just as long, if you keep it at stock temps right, its the heat that screws them up isnt it, or high voltage?

Thanks

so, is 1.25 the max then?

Hawky89 · 3 Mar 2008 at 16:08

well what is fine? i might not be in a position to get a new cpu if mine dies!

Hawky89 · 3 Mar 2008 at 16:12

cool, thanks, i got mine early and so didnt pay as much as it is now

So would about 1.25 be the max i should use?

well, i put the fsb up to 350 on stock volts and it was stable, then i put it up to 355, when i booted into windows the voltage had gone from 1.192 to 1.3, it was still on Auto in the bios so i went back in there and manually set it to 1.19375 which was the closest to my stock volts, now i run cpu z and get the following:

355 fsb

3.2 GHZ clock speed

1.16 volts

Its gone down even tho i set it to 1.19, why is this?

Hawky89 · 3 Mar 2008 at 16:36

so it seems im clocking my cpu on lower volts than stock

, got 360 fsb now, with 3.24GHZ at 1.168.

ok cool, thanks, but if its stable do i really need to up it?

Hawky89 · 3 Mar 2008 at 16:42

cool, so my cpu is overclocked, under volted, and so performance gain and temperature decrease, excellent! im 2 degreess cooler at idle now

Hawky89 · 3 Mar 2008 at 17:38

well my cpu was at:

3.0GHz, 1.19v, 40 C

Now:

3.24GHz, 1.16v, 35 c

It all looks good to me

Hawky89 · 3 Mar 2008 at 21:15

Now ive got:

3.3 GHz, 1.178v, 36 C idle

Does that sound alright, considering im still not at stock volts yet.

Hawky89 · 3 Mar 2008 at 21:29

what do you mean by that?

Hawky89 · 3 Mar 2008 at 21:39

yep, ive been using prime 95, temps are getting high so im waiting for my Arctic freezer to come tommorow before i go any further, after prime 95 for about an hour and a half ive got temps of about 65 degrees, ive also been playing games which is stressing my cpu to and raising the temps

Hawky89 · 3 Mar 2008 at 21:57

checking my temps just now and ive got 3 programs that i can use:

Coretemp: 50 degrees

AI suite: 38 degrees

AI probe: 38 degrees

I'm guessing the bottom to are the same as they are both ASUS programs and presumably using the same sensor, was wondering whether the coretemp one could be right?

I see there JeffyB you have the same chip and board as me, what temps are you getting? do you get the same difference between asus programs and coretemp?

Hawky89 · 3 Mar 2008 at 22:05

oh well, as long as i see a drop when i get my arctic freezer pro tomorrow ill be happy, was worried about burning out my new chip!

Hawky89 · 4 Mar 2008 at 11:10

If my chip is undervolted then surely the courrent will be higher, would this damage the chip? atm it 0.02 volts lower than stock with an 11% overclock.

Hawky89 · 4 Mar 2008 at 11:23

How accurate are the voltage readings for the new cores? if temps cant be read accurately, can the voltage?

Hawky89 · 4 Mar 2008 at 20:21

well i got to 3.6 GHz on stock volts of 1.19, so i think ill be safe, super pi, 1 million in 13.166 seconds

im not clocking any more, might even put it back to stock, i dont want it waring out and 3 GHz is probably enough for me.
