Has anyone killed an A64 from voltage?

[nn_step]

Well I like to keep most of my chips alive because when they stop being in my main rig, I put them to folding.. and when They die.. I sell them on Ebay

[mnewxcv]

sledgehammer for 4 months, 1.775v 24/7. first time i mounted the hsf wrong and it went to 90c in bios, still running fine.

I think OPB take the crown here, he killed more cpu with high vcore than anybody else!!

[bazx]

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.......

pre release chip,sample,over volted 1.85v

Ummm, if you didn't notice, I was being sarcastic and BTW, that quote is taken out of context, IIRC. I was speaking of a screenshot and not of sustained use @ that Vcore. Ok, Mr. OverclockingMasterGuru - please tell me you're running your FX57 @ 1.8+ Vcore for 24/7 use cuz if you're not, then you're not an OC'r

You need to cool down dude its only dots on a screen

ps: i like this word "OverclockingMasterGuru" can i use it it my sig?

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)

I didn't think that you can check vcore with a DMM... if so, how?

your joking I hope...................................

Sure you can, I do it every time. Somebody posted the photo with the points you go to just recently.

And yes the OS readings from the sensors are off on my SLI-DR.

Here is what I got for two runs:

Volts 1:
- set: 1.325 * 110% = 1.4575
- reported OS: 1.41
- measured voltmeter: 1.468

Volts 2:
- set: 1.45 * auto = 1.45
- reported OS: 1.41
- measured voltmeter: 1.449

I am, In Reality I put them on poster board like trophys to my ablity to push stuff too far...

Dont scale up that vcore, if you dont have the collin
I ran FX57 with -90C average evap. temp. for the past 2.5 months for about 7 hours daily @ 1.6/1.7V for surfing etc, and 1.8V for benching. Last week the HSF came off by itself and the cpu went topless.

LOL....OPB was telling me about that.....so it still works?

[zenzog]

Mmm... naked A64...

I don't think I can kill mine using this K8N neo2 plat... max vcore on this bios is 1.65ish

you can do alot more on a Neo2 using corecenter (up to 1.9V).

RIP @4076Mhz ..Not because of Voltage...probly shorted or crushed core. The SLI-D and cascade still going strong though and colder too
Time to hunt for another 0516 cabce...

PM me....I may know someone that can get you one

I've had an 0441XPMW newcastle which loved voltage, i've pumped 2,05V through it and it even went faster than 1,75V/1,85V/1,95V on air. Just after one PiFast and SuperPi 1M run it shut down because it reached 70*C
But CPU still going strong

Could you link me to where you found that info? I really thought it wasn't possible b/c the voltage goes right to the core. I figured if there were a spot that it would still be off, but I'll give it a shot if you link me.

One athlon xp-m @ 2.3V on air Well, actually NF7 undervolts a bit so it was like 2.25V. I knew I was gonna kill it because I was pissed off. Worked fine @2.1V though.

I forgot where I got it from, this is my local copy of the pic. I hope the original author doesn't, otherwise let me know.

yep killed my 3000+ venice with 1.9v and fan stoped working while I was at school and when i got home no more workey but the venice i got back from rma is nice also.

Wouldn't your mobo shut it down itself on an overheat?

[g0dM@n]

It might, but I've gotten a winchester to hit 67C and keep loading at that temp. I did that when I first got my A64 a long time ago and wanted to OC it on stock cooling. If his fan stopped working then maybe the temp didn't go up so fast.

Think about it... there is a reason why it is called "load temp." That is where your cooling system pretty much bottoms out (or tops out actually) and stays at that constant temp. It all depends on your case cooling and the CPU cooling method. Think of falling speed due to gravity in reference to terminal velocity... there is a maximum.

What probably happened in his chip is that when the fan stopped working the chip went up in temp really fast. It probably eventually topped out at a certain point, let's say 80C. Then what happened is that the case airflow came into effect and created this new "maximum" cpu temp for his system. The system couldn't break 80C b/c it reached its critical point. If the mobo was set to shut off at a higher temp, then the chip probably maintained 80C for a long enough time to kill itself.

I'm not sure if this is what happened, but I'm just taking a wild guess. That, and also this is just generally speaking. If a CPU fan can cause a critical point for a LOAD TEMP, then it would only make sense to say that without a CPU fan the case fans will cause a new, yet higher, LOAD TEMP.
