C2Duos/Quads - Vcore or Temp is a chip killer ?

now that the quads are out I'm pushing my 1 year old E6600 to the max (its never been a great overclocker)

but am I pushing my luck - going to 1.55V Vcore and beyond - the P5B Deluxe I am using has quite a bit of Vdroop so its actually quite a bit lower than that.

temps at 1.375 Vcore @ 3.3 gig are 60C under Orthos small load - measured by TAT.

I'm not too concerned about the temps (unless they get above 67C or so) - but can I keep pushing the Vcore or could I end up with a sudden CPU failure ?

Has any C2Duo yet failed with too high vcore ?

thanks for any help, Mark.
 
Nope its near impossible to kill a chip these days unless of course you shovel some insane voltage in the bios and even then the chip would throttle it self down. Temp wise it's the same thing keep the chip under 85c and it will be a happy chappy. These Intels are pretty much bomb proof :D
 
couldn't agree more tom, keep shoving volts through until it's all too warmi always go by temps i'm dealing with rather than the volts i'm shovelling
 
On dual core Ive had 1.62v and 83c.

The 1.62v I used for months and 83c was about 10 minutes. Ive idled the cpu at 70c every day for months though, no problem.
Presently its running at stock and a cool 36c :)

I cant see you having a problem so long as you edge it up and dont ignore crashing or freezing
 
For 65nm chips, I've always kept a conscious limit in my mind at ~1.525V. Then again, temperatures are a problem well before that :o

think about it, people on water can put more volts through their cpus, not bercause it magically makes the volts matter less but because the temps are cooler *nods*

I think i'll have to overclock my cpu a bit more then :D
 
thanks to all of you - looks like I can push a bit higher then :)

Its only got to last about 4 months - I can't see me halting off a Quad-core any longer than that lol ! I'm very tempted already

Mark.
 
Sorry to dig up this oldie but I thought why post another thread on the same subject? :)

I've decided that my problems getting to 3.4 must be vcore related and I'm upping the vcore and it's getting further in orthos blend test (2 hours @ 1.525- was only about 5 mins at 1.475). Temperatures are (I think) very good @ 56 both cores under load in Core Temp (latest beta).

Am I right in thinking that the volts are okay as long as the temps don't get too high? I'm prepared to go to 1.6 as long as temps don't exceed 62 per core to guarantee stability.

I think for such a high vcore my temps seem very good, what does anyone else think? Should I keep upping till I get what I want? :)
 
That's pretty high voltage for 3.4ghz on an E6600.

Whilst your temps are ok, personally I wouldn't try to push 1.6v through it for trying to get stable at 3.4ghz. Maybe 1.55v max.

that's VERY high voltage for 3.4Ghz on E6600.

i've got my Q6600 rock solid at 400x8=3.2Ghz with only 1.39 (1.34 after Vdroop). and max temperature was never above 65c (~40 for web and desktop use, ~50 for gaming, ~60 for prime-ing)

as far as i understand, higher voltage ==> higher temps. lower voltage ==> less stable but better temps

so as my quote stated there, voltage = heat, as long as your cooling can handle, you should be fine. just make sure your fan don't fail. (see tomshardware)

Depends on the chip, chip X may be able to do 3.4Ghz on 1.3v while Chip Y of the same rev and stepping needs 1.4v, luck of the draw. Theres no point in a cool unstable pc so that statement really doesn't make a lot of sense lol. As for who kills more, volts or temps, its a fine line and arguments can be made for both sides, there comes a point in adding voltage where it becomes dangerous for the process and architecture of the chip, even if you cool it with Phase, LN etc.. it'll just tear up the insides and cause electromigration at an accelerated rate or cause some other damage which may kill the chip in as short as days or even hours (have seen this with mad overvolting) no matter how cool it is.

Agreed, cooler chip might not suffer from heat problems but that does not automatically mean its being run at a safe voltage.

The only thing that'll kill a Core2 is excessive voltage, for air and water you probably won't be able to reach a dangerous voltage if your using Prime to stress test.

Also be aware that the North Bridge might be holding you back... I was wondering why my chip was randomly failing at 3.6gig - i.e. sometimes I could run orthos all day no problems and other times it would kick out a rounding error after 30 seconds... and then I upped the NB another 0.1v and found I could drop the vcore back 0.09volts and still be stable, whereas before dropping back that much would have been instant failure in orthos...

Also above 1.4 vcore the temps kick in quickly... your not going to get load temps under 60C on (normal) air cooling when the vcore goes over 1.48 or so.

While I personally like to keep my chips to 60C max you _shouldn't_ have any trouble long term running a core 2 duo at 60-70C aslong as you stay under 80C for long term... running 80+C long term will (relatively) quickly break down the silicon.

That statement is contrary to most of what I've read about Intel processors for the last 3 or 4 years, so if you have a reference source I'd love to read it.

If you consider how we measure temperatures these days, everyone uses CoreTemp or TAT and we generally deride those who quote the motherboard socket temperature as deluded, but Pentium 4's only ever had the socket temperature to read, and they run at 55-65C socket temperature. If you think that 45C socket equates to about 70C core temperature with a Core2Duo, the cores on those Prescott P4's must be running close to 100C, and they're not failing in any great numbers at all.
 
I had a P4 560 only till a month ago, running at stock. These were very toasty chips, even with a Zalman heatsink (forgot which one now) I was touching 80*C most of the time while gaming. After 3-4 years it is still busy heating my room :D

Not because ive set it on fire either :p as tempting as it has been
