Partially damaged CPU ffs
show user profile  9krausec
Long story short- I'm an idiot.

Long story long- Left computer rendering over a weekend, it crashed. Had my 2600k over clocked during winter and forgot to pull it back to a safe temp zone for the frekkin hot summer months.


Question- Is it possible that I could have a partially damaged CPU? I can boot into windows7 (64 bit system) fine most times, but sometimes it will turn off and then on (x3) then I need to futz with it (power off on from power supply) to get it to boot up.

I reverted all CPU settings back to factory and it still seems to wanna crash every now and then when the cpu temp is only at 40C.


Note: I realize I am a fuck-tard. No need to point out that I probably shouldn't be over clocking my shit if I don't know what I'm doing (but you do learn from fuck-ups).


So, can a CPU be partially fried and unstable, or is it dead or not dead (one or the other).

Cheers!

Someone else would probably be better suited to answer this, but, before you spend money, maybe you should take off the heat sink and re-apply with new compound. Maybe it fried away. I could be wrong, but it is worth a couple of bucks to try.

thanks man! I don't think it has anything to do with heat at this point though since it's crashing when at 40C (internal temp).

Testing all the ram tonight (special thanks to lion debt for showing me this free ram testing program, way to be awesome).

I put together a few purchases tonight that I will make tomorrow (when sober). Pretty sure it's the CPU but I will make damn sure before I throw money at a problem randomly and expect it to fix itself. I ran Prime95 on the setting that mainly tests the processor, and it crashed instantly. So if the ram checks out, then like I said, pretty sure it's the cpu.

So, end game is an Ivy bridge. Bought a car radiator off of ebay. Going to hook that up to the CPU and then dip everything in liquid nitro. Going to get 12ghz out of this new ivy bridge before this whole thing is through (I kid).

But for serious, I'm going to post up some of my water cooling orders for some of you smart folks to double check so that everything fits (spent like 4 hours researching about that stuff tonight).

CHEERS MF! Oh yeah, and I got my motorcycle out today!!!! WOOOHAOOOO!

cpus generally don't partially break especially from heat, i've seen some chips degrade due to microsecond heat spikes from high voltage but im pretty sure the last few generations of intel cpus aren't even capable of damaging themselves from overall temperature (they just turn off before).

can you elaborate on the crash? does it happen on the random or specific tasks? does it bsod or freeze or reset? if freeze is the hdd light on permanently? any other details..?

Don't want to be a is-it-plugged-in guy, but are you sure it's the CPU.
Have you ruled out software for starters (clean install)?
What about other parts? If you have some to spare or a friend with the same socket

I would look at the PSU too , Ive had one of the 5volt lines go on one in the past and it made my PC do alsorts of odd things.

Thanks for the replies. I haven't been on the computer much for it is currently torn apart. I think I found out the issue, but here is exactly what I was running into.

Problem: Would bsod once in a while with basic operation (internet browsing while I research is my basic operation). Then, starting prime95 test (blend or any other test on prime) it would instantly freeze the screen and a moment later bsod with errors varying, but mostly 0x000101. This just started happening after the weekend when I left my computer rendering.

What I tried: I instantly jumped to the conclusion that it was the CPU for the computer actually did crash over the weekend when I was rendering. I have my 2600K OCed and the temps usually peak during render times at 74Cish, but I haven't done any longer renders since winter (my computer was the only source of heat in my room for the flop house I was living at had no heat)... So..

I tested all sticks of RAM one by one, tested all mem slots on MB one by one (I actually did find a bad stick of ram, but taking it out had no effect on the issue). Removed one of 2 gfx cards and updated the display drivers. Researched the piss out of the memory dump code. Downloaded a program to read the dump files (pointed to hardware failure). During all of this (first thing I did actually) was set my CPU to default in the bios. I replaced cmos battery and reverted to default bios settings.

So, I'm pretty sure it's the CPU at this point since all the q-codes on my MB are good to go and in the green... I called a PC repair shop also and asked the guy if he has ever seen one core on a cpu get all fucked and he has seen that only a couple of times with the dual core CPU units.

I have another stick of ram and a cpu inbound, so I'll install them and see where I'm at (keep you guys up to date). Thanks for the replies and if you have any advice.

@DannyMax- actually really good idea. I am running a 1200w Antec half ass modular plugged psu. If the problem persists with the new hardware, then that would be the only other thing that would be crapping out.

Cheers!

Edit: on a side note, the night I posted my last post, I went out to the bars, got really drunk and sang along to journey. Not a high point for me, haha.

well 0x101 is very common for either unstable imc or cpu (mostly cpu). You could try bumping your VTT up a few notches, if it don't help then there is no other option than a faulty cores :|

Yeah. Sad truth. Looking on the bright side, I sort on enjoyed opening everything up and putzing. Systematic trouble shooting is sort of relaxing once in a while. This is also going to he an excuse to upgrade to Ivy Bridge.

Thanks to you guys for lending a hand. LionDebt, I really appreciate you pointing me to that memory testing software. I can't believe I was working with a bad stick for a year. Thanks for the advice Marko too. I would also like to thank my mother. I told you I would make it, thank you for believing in me. Hah!

Sure its not the mobo itself I've saw something similar that turned out to be the board.. It's really annoying having no real hard evidence between mobo cpu psu etc..

Nice speech BTW very moving :)
