Fried Athlon?

[Hamlet]

Have anyone actually managed to kill their Athlon? 1.9V was said to be OK, is this true? What's the max Vlimit I should push my cpu to? (FCC32 cooled)

Athlon 500/MSI 6167/128mb/7200rpm/SB128/G400Max/Win98/RH6.0

I haven`t heard anyone that has fried their
prosessors .

Personaly I have tried 3 different Athlons @ 2.05v ,one from week 27 and two from week 42 and no problems att all.

Frying processors from overvoltage is pretty rare actually. There have been rumors around that the athlons are "Weak" (see: Dell's reason why they're not carrying Athlon's) compared to P3's, but I'm not sure how much stake you can put in that.

I'd try the pxr in another board if you can. If it's still dead; well, i'd cry for a while, and then blame something like static or severe overclocking without cooling.

Usually the problems with overvolting and overclocking appear while they're in the OV/OC state, and then go away once you set the thing back to its specs.

Of course, both overclocking and overvolting can cause silicon stalactites and stalagmites to form, leading to less tolerance and 'fusing' of silicon paths as well as arcing within the chip. (Pretty nasty sounding, huh?) ... Which is even more critical with these smaller and smaller die sizes.

So damage can be done but usually you notice lockups and what not before it's irreversible.

Even damage by static is kind of rare. Before suspecting any of the above i'd make sure the dang thing is seated correctly. I've had more "Dead processors" turn out to be just fine due to bad connection.

Hello... my name is ami. and this is my signature.

It's not dead =)... Far from, actually. I was just curious how far I can push it. I have it rock stable at 650 with 1.8V, and i was kinda thinking of trying 700 but then i need to increase the voltage even more. I guess atleast up to 1.9V is OK then?

Hamlet,
I haven't seen a "fried" (thermally) Athlon... but have seen damaged ones. The damage is caused from chipping the edge of the cpu where it meets the heatplate. This cap is the substrate which the core itself is... the chipping actually fractures through and permanently damages it. This is easy to do and please if you consider mounting a HS directly to the cpu be very careful.

Don't go above 1.9v! Also using a better cooler than a FKK32 would be essential in possibly achieving higher results.
I'm in the process of building two super HS setups.

I have a MASSIVE HS that'll be cut down to custom fit Athlons (WAY bigger than a VOC32 or an Alpha) and the other is a water cooled system using a transmission cooler (radiator) mounted in the top of my InWin Q500-300A full tower. Later I'll be adding some Peltier's to both setups.

PH,

This is called "intrinsic growth" and is associated with migration of various metals causing electrical shorts. Yes it is very nasty, but cpu's don't seem to be effected by this as much as RF circuits used in communications eq.

Ok, but below 1.9 is usually OK?.. I'm not that big OC junkie to mount a fridge on my machine, so i think the FCC32 will do for me for now =)... only sad thing is that i havn't found any software that can use the sensors on the MSI6167 board (if there is any) so that i can see the temp on the cpu.

But, it runs as said rock stable at 650mhz with a standard cpu fan. I just switched to the FCC32 recently, since i wanted to try 700, but it worked just as well with the standard fan at 650. Well... gonna try 700 soon then.. 500 core suxx... =(

Uhhh...Greebe, why is above 1.9v bad? Don't forget about me.....

[PurpleHaze]

Greebe, are you saying that keying up my Nextel i1000 next to my CPU won't make it go faster?!

I would assume that above 1.9v is bad because it's just plain too high. As voltages get lower, well, smaller increments are bigger deals... Back when things were 5v, such small increments wouldn't matter. but these days... things are much more specific.

That's my guess. Don't fry any CPU's on that.

[Wombat]

It's just that I'm running @ 1.95V

Then how much voltage can a P3 take?
Or how much can the new coppermine stand?
