How much vcore is too much?

[Dr. Possum]

It seems everyone has a different opinion on this...I just wanted to know how you guys felt. As long as temps are reasonable, how high would you consider running vcore? Has anyone burnt up a processor because of too much vcore?


I'm mainly concerned with AMD processors, but Intel input is certainly welcome :D

dont know of a limit with xps, never heard of an overvolted xp that died. 1.8 is max id set a P4 to, 1.70 is 100% safe i think

[Swiftdeathz]

1.85v is usually the highest on GOOD air cooling...

Some don't like running over 1.75v though on the newer 0.13 XP's...

[saaya]

well anything over 1.8 only gave me an extra 100 or 150mhz increase with much higher temps, so 1.8+ only makes sence with really good aircooling or water or even phase change cooling.

I would say, How long do you want the Processor for?? Higher voltage = Shorter life...I run my AMD XP2500 at 1.7always, xcept when im overclocking, then i go to 1.8..then return it to the lesser...I think most AMD XP chips run around 1.6 or so..
I have a XP2000 XP2700 and a XP2500
Im no willing to see just how much V will fry them:flame: , if you find out let us know:lol:

I've been running 1.83v (real in mbm) through my 2100+ for a while now on air.. these lower end tbreds are so cheap it's almost like buying a loaf of bread when you kill them.

Currently running my Barton 2500+ at 1.95 VCore (225x11) with 1.7 Chipset Voltage, 38 C idle, 42 full load. LOL am I setting myself up for my processor to suddenly die on my down the road? I mean I don't see the processor getting hot, hell I hold my hand on my heatsink with my case open all the time and I can never feel any heat.

Those seem like nice temps... 1.95v is pushing it on air and I assume that's what you are using...

As to how long it'll last... your guess is as good as mine... But keep this in mind... If you are worried about the chip dying on you, you shouldn't really be overclocking in the first place... ;)

[Dr. Possum]

Please, if you've ever burnt up a chip, post how long you had it and what vcore and cooling you had on it.

I've never burnt a chip out... in fact I still have an Intel Celeron 300A at 450mhz with and it's still purring long in my brothers PC...

I've overclocked over 5 chips so far in my lifetime and I haven't had one burn out...

As long as you don't over do it on the volts and have good cooling you'll be fine...

By over doing it I mean, if the chips default is 1.65 don't put more than .2v into it... once you go over .2 volts you start to get diminishing results on your overclock...

Now if you have some insane cooling like water or vapochill or prometia then you can put more volts... but on air, I'd not go over .2v default... tha'ts just me though, I'm not as daring as some... :D

Exactly, I have no fear of breaking my computer parts because failing is the first step to learning. I have already broken a 9500 Pro the first time I removed the shim, and I removed my second one after I RMA'd the first one in about 10 seconds and all went perfect. My statement wasn't due in fact to fear, but moreso curiosity. I'm curious as to whether or not others have burned their chips running high VCores. Hope this clarifies my statement :toast:

[Swiftdeathz]

hehe well good luck... since you seem to have insane air cooling with that noisy Tornado and SLK-900 you probably would be safe with even 1.95v but again I wouldn't do it... :cool:

[Dr. Possum]

But this is what I'm wondering...is frying chips all about temps? Because then you could just say 'keep it below this temp and you'll be fine'. I thought there was more to it than that, that just the act of pumping more power through it became increasingly dangerous and damaging. Adding the power also creates more heat, but overheating issues and extraneous vcore are different entities. That's how I understood it anyways...feel free to prove me wrong :D

No it's not all about temps... Nobody will know if all the people running their chips with Prometia's at sub 0 C temps will die any faster than not as extreme overclocked chips... Usually long before the chip is gonna die they'll already be buying or have a new faster chip...

Ya I'm liking my temps with my Vantec Tornado, 37 Idle now :). I don't think its loud actually its right next to my bed and I sleep with my computer on. It does wake me up earlier in the morning tho lol :D oh well thats not too bad a thing ;)

[saaya]

i overvolted and therby killed a celeron 700 once, but that was with 2.2v+ and default was 1.5 hehehehehe :D got it to 1.2ghz though before it died...

i wanted to find out how much voltage it can take (temps were still ok, about 40-50°C) and it seems 50% is the absolute max a cpu can take in voltage increase(without frying inmediately) :D

well thats for 15µ chips...

[Dr. Possum]

I'm still looking for people who have experience in current CPUs and overvolting...

Bump.
