Has anyone killed an A64 from voltage?

**afireinside** · 10-13-2005, 05:59 PM

A certain someone will not let up on thinking voltage kills them and insists I will fry all my chips. I've run all my A64s (a claw, venice, 2 diegos, and a diego opteron) to to 2v for extended periods of time and they all run just as good as always. So has anyone killed a chip from voltage?

**Aphex_Tom_9** · 10-13-2005, 06:17 PM

ive seen my current chip degrade a little after running 1.9 volts for a few months...

**Runner** · 10-13-2005, 06:20 PM

DFI and Oskar Wu have.

Sorry, couldn't resist

I think its pretty well common opinion though that running that sort of voltage is definately going to shorten the lifespan, this is xtremesystems.org though, you break it and you buy something newer and hopefully better

Getting a new goodie is half the fun of it.

i killed about 15..
and an additional 3 in the process of trying to unlock them...

Wow, so what'd you do?

**nn_step** · 10-13-2005, 06:43 PM

just go to the A64 unlocking thread for the 3
The others were simply too high for too long...
Hence my current chip and it's overclock is at 1.4v
I could go farther but I love this chip...

You must really have some "special skills" to be able to pull off something like that

I've had maybe 15 different AMD CPUs (4 A64) and have never killed even one from overvoltage

All were seriously "vcore-tortured", on a daily basis.
I only killed one A64 (Winchester) but that was because I was stupid

It died at +95C @ 1.7v

**Absolute_0** · 10-13-2005, 06:50 PM

What voltage were these chips run at? What cooling was used, what were the max load temps, and how long before they died? If you don't mind sharing of course. If you have lost that many chips, you should share your experience so we can avoid the situation.

**texuspete00** · 10-13-2005, 06:56 PM

NO... then again I haven't had the same one for more than 2 months.

I did kill one with homemade phase kits, too much mounting hardware created a short I guess. Speaker wire from the mobo melted and other notices. The mobo and the newcastle died together. They smile down on me and my SD, as they know there will be no letting up.

I killed a 3700 Clawhammer about a year ago when I was insisting that it bench 3D@ 3ghz on water. As I recall, I was pumping 2 volts even thru it at the time.

**haPpydUde** · 10-13-2005, 07:05 PM

Ya, when my old dfi nf-3 screwed up and gave 2.3v to the cpu, It posted I went into the bios saw that huge number and hit the switch on the back of the psu. But the cpu never posted again.

1.7v, 1.8v,1.9v and they were all phase change cooled to -60C
They died over the course of 1-2 Years
I now strongly suggest that you keep your Vcore at 1.55v or less when ever possible..
Oh and these chips were pushed to their max 24/7 to boost my folding score..
They just seemed to wear the

out..
other chips set at 1.6v and below seem to still be working nicely with no probs..

**s7e9h3n** · 10-13-2005, 08:26 PM

As I've always stated, high vcores are more damaging to your cpu's that high temps. The A64 may be able to withstand 2.0+Vcore for short periods of time, but you're definately cutting the life expectancy of the cpu way down. BTW, I can thank a faulty DFI for somehow killing one of the most awesome cpu's I've owned to date - an 0435 CLAW FX55

**chinkgai** · 10-13-2005, 08:45 PM

just out of curiousity, when you guys report ur vcores, is it what you set in bios or what displays in windows?

for example, i have my vcore on a dfi at 1.45+110%

so when stating my vcore, would you state its:

1.45v
1.55v (what windows states it as)
or 1.45x1.1 = 1.595v?

and finally, assumings its 1.595 and running 24/7 at around 32-33c (full load of both cores, ambient when idle)...its not too high is it?

**purefun65** · 10-13-2005, 08:54 PM

I fried a 3400 clawhammer. pumped 1.8 into it for months,one day wont post.

**Perc** · 10-14-2005, 12:00 AM

yup sure have it was a DTR3400 was trying to push 1.8v thru it with a v-dimm of 3.4v using a mach1 pasechange unit.... to this day the cpu sits on my desk in an ashtray to remind me that voltage kills......

peace perc,

**purefun65** · 10-14-2005, 01:59 AM

mine was a mobile 62w on water. couldnt take the beating lol

**bazx** · 10-14-2005, 02:18 AM

figers cross never

the thing is

if you really want the mhz you just have to do it period

how could you just sit there and say are well thats all the oc i can get @ 1.55v and call your self an over clocker

and as for life expectance of the chip who here intends to have the same chip next year

**phobix** · 10-14-2005, 03:07 AM

I run Phase Change and I never exceed 1.6v. Folks we are talking a 90nm process here, electron migration is a reality and will be even more so once we go to 65nm process.

Excellent question. Run-time display is usually 0.07 volts lower than what I set in the BIOS on my SLI-DR.

**Shark-357** · 10-14-2005, 09:19 AM

I burned my old wini 3200+ CBBFD when i pumped 1.95V in to him

**ImportantAwareness89** · 10-14-2005, 09:21 AM

Ok, you guys need to stop basing voltages off Windows readings. You need to compare your BIOS settings with a multimeter and then tell us hwo much your voltage really is set at... USually BIOS settings are quite correct for me (DFI LP NF4 Ultra-D)

**MrSeanKon** · 10-14-2005, 01:42 PM

Not yet!

But I burned a Barton two years ago!

I think A64s are stronger!

So I guess I can't call myself an overclocker because I don't want to take the risk and kill a cpu which costs $600+ or one which is a pre-release sample and won't even be available for a few months.......
