Quick Question about overclocking over time

post #1 of 11
Thread Starter 
Background:
I overclocked my i7 930 from 2.8 to 4.2 ghz about a year and a half ago with about 1.325 vcore, and tested it for 24 hours with prime95 to ensure it was stable.

Leap forward to now, suddenly I am getting a BSOD with code 1d (a thread on this forum indicated that this code corresponds to needing higher vcore). Running prime95 crashed the system in less than a second. I raised the vcore to 1.35 and it is now able to run prime95 (only tested for 5 minutes).

My question is:
Is it normal to see the processor require more resources over time like this? Is this a sign of eminent demise for this processor? (i.e. should I look into building a new system?)

Thanks for the advice

Overclocked processors can become unstable at any time.

my 1100T run fine for a whole week at 4.3Ghz, then randomly BSOD'd while I was on OCN, so my point is, this is normal, it seems like it was just a bit dodgy from the start.

(Please note, I also benched with Cinebench, Prime95, wPrime and 3DMark Vantage)

I hope I helped.

Its from degration of the cpu which will happen eventually with overclocking. Pretty much when you cant keep the temps under check while keeping your overclock.

Which of the two options you have is either one drop your overclock at same vcore which will keep same speed of degrading or increase vcore to keep same overclock at risk of degrading the cpu even faster to the point it wont run on stock.

This is why people try to find the best voltage that wont kill the cpu faster then they will be able to replace it. But as with everything not all cpus will act the same especially when it comes to degrading of the silicon of a chip.

It is already giving BSOD's on "factory" settings. I have increased the vcore to 1.3 on stock (2.8ghz) and it is still giving a BSOD every hour or so (still code 0x1D).

Should I assume the processor is hopeless and look for a new one?

Thanks for the replies
post #5 of 11
well if you can find one for cheap, but it also could be the mobo so yeah something is definitely going out especially if its all set to stock.

EDIT
But that is the classic sign of a dying cpu.

ahhh just thought of it do you have a multimeter to make sure the 12v line is stable as that will help rule out psu. read the voltage from boot to windows. And from windows too to well once it BSOD. And will it bsod during loading windows or after?

sorry for the fragmented thoughts if any as I havent gotten alot of sleep lately .

Would there be a way to test this before investing ~$200 in a new processor in this system? smile.gif

yeah lol, he just gave you a way to try and test if its psu, you could try the cpu in a different mobo to see if mobo is the problem, but most dont have a spare laying around so this might be hard to do

If you have another board to test it with I really dont have the slightest clue other then another cpu. I mean you could keep the board for bulging caps or something cause if the power delivery system is failing it would explain why it wont run on stock vcore.

But testing everything to make sure is the best way to go. PSU first since it powers the system and mobo would be next to rule ot since it delivers the power to the cpu from the PSU, so if a proven good cpu has same issues in your board but psu is showing fine voltage readings then it has to be the motherboard by ruling all the other items out.

well put and probably your best solution till new info arises
