How to tell if CPU is heat-damaged? + RAM issues

post #1 of 9
Thread Starter 
Ok I'll make this saga as brief as can be:

I made a new system and the DDR3 1600 RAM I got wouldn't allow POST and boot. MSI said the board might just not like Mushkin RAM so get something else (or of course the RAM might be bad but seeing as I have no other DDR3 1600 capable mobo on hand the point is moot if it wouldn't boot). I ordered Kingston DDR3 1600 HyperX RAM (one of the MSI tech's recommended brands) and got it today. I put it in. Now here is where things get interesting and realllly stupid on my part doh.gif ...

When putting in the new RAM I had to disconnect the wire for my H80i that links it to the sata power from psu....and I forgot to reconnect it when closing up the case.......

So when I booted up I saw that the new RAM was only 1333! After all the trouble I had last time I was so enraged by this that I discounted the BIOS reading of my CPU being 70...80...90 (OH S***) as just a temporary fluke from the new RAM or something....I put the RAM of auto and selected it to DDR3-1600 (what it's supposed to be) and rebooted. It turned on and died suddenly. Still enraged and thinking it was being considered a failed OC by the mobo, even though the RAM is supposed to be 1600 in the first place I cleared the CMOS properly and rebooted only to have it turn off again instantly.

Intrigued I opened the case, saw the disconnected H80i power cable and it all fell into place. The mobo was shutting off to because the CPU was getting too hot! I know I know slap me...Noob mistake....

I obviously connected it and rebooted and thankfully it worked....only to have my boot drive be undetected. Frantic again I checked the BIOS and saw when I reset the CMOS it obviously reset from AHCI to IDE...and my OS is on an SSD! Thinking that somehow I might have just inadvertently ruined my SSD by booting into IDE I reset it AHCI and rebooted. It still didn't detect it. I replugged in everything and thankfully it was finally detected. I did notice that the Click Bios II UEFI was acting odd though and the mouse pointer was laggy and sluggish. I hope my mobo and/or CPU were not harmed by the temporary heat.

So my questions are these: Is my CPU ok? Everything is reconnected and the H80i is fully operational. Should I reapply TIM for the hell of it? Is my SSD ok? Anything I need to know? Everything should be back in AHCI. Annnnnd finally, *** is up with this board and 1600 RAM? It has the latest BIOS supposedly and shouldn't have any RAM issues. MSI techs assured me it's rated up to DDR3 1600 non OCed (though I spoke to a guy who told me he just plunked 1866 modules in there and it worked fine go figure mad.gifmad.gifmad.gif)
The mobo still reads it as 1333 and at this point I'm scared to do anything lol....please help.
Any comments would be greatly appreciated thanks a lot. biggrin.gif

It's almost impossible to damage a modern CPU with heat. It will throttle back and/or initiate an emergency shutoff to protect itself. Usually all CPU damage is either physical or caused by using extreme voltages. Odds are, your cpu is fine.

If your CPU is damaged/fried then the computer will not post and will show no display.

CPU's are very durable piece of hardware and tend to be the last ones to be the culprit of a problem. I doubt its your CPU if youre able to still POST and access BIOS.

Heat wont really damage CPU's unless you fry it and overvolt it a loooot. CPU's should have thermal protection to shut themselves down before it gets too hot.

^^ Great! Any idea about the SSD or RAM though?

Update: It appears my SATA 1 is dead now or something. That's why the SSD boot drive wasn't detected. I swapped it around my storage HDD and now the HDD isn't detected. Ever heard of a SATA port just dying like this? I'll avoid it for now and see if everything is detected. Any thoughts on the RAM issue that started the whole mess?

Edit: Actually it seems that it still won't detect HDD. Yet when I first booted it ONLY detected the HDD. It seems my mobo can't detect two drives at once now ****..

Im not really too sure but all i know is:

1) Your CPU should be fine if you can still access BIOS
2) Your RAM speed problem sounds like the problem is either with the RAM or your motherboard
3) Booting into IDE or ACHI with SSD should not damage your SSD. Your SSD is probably fine.
4) If you tried resetting your CMOS already and your drives arent coming up on your SATA ports then try calling MSI about that. You said you only called MSI regarding the RAM. See if they can tell you something or help you with SATA issues.
5) If all else fails; it could be your motherboard not being able to set the proper speeds for RAM; is the RAM voltage/timing/speed all correct and set? If your SATA connections are also going out then it might be a sign of a faulty motherboard.
6) If all else fails; you could try a BIOS flash (but honestly dont flash if you dont know what youre doing) and see if the SATA ports will start working again or to see if your RAM speed can be set back at 1600 without an automatic crash/reboot (like you mentioned).
7) In gaming the difference between 1333 and 1600 will be almost unnoticable. If you are doing other things that require a lot of RAM usage then that may be a different issue.

You posted two threads back to back about your 1333 RAM issue, I won't repeat myself here. Go check that one.


CPU is very tolerant of heat issues - the only time you'll damage one is if you fire it up with NOTHING on the CPU. Even a water block with no pump running and no fans running will conduct SOME heat off the CPU, enough control for the chip to do an orderly thermal shutdown to protect itself. I think you're fine in that regard.

Thanks for all the feedback guys. Somehow the HDD is back working again. Apparently it isn't showing up where it used to in the BIOS boot menu but is now under a separate tab called Hard Drive Disk BBS properties. The SSD appears fine as does the CPU. As to the RAM I will admit my mistake: Seeing as all I ever owned was 1333 RAM when I put in the 1600 I assumed the board would set it to 1600. I didn't know I had to manually set everything to 1600. I know noob mistake lol rolleyes.gif
Thanks for all the help guys sorry for spamming lots of pages lol I freaked out over the last few days. Rep + to all cheers.gif
