CPU degrerad after a few months

post #1 of 32
Thread Starter 
A few months ago I overclocked my cpu to 4.7ghz (1.345vcore the bios) I drove a lot of stability testing program:
Prime95 "1344k" and "1792k" and 12 hours of Prime95 blend 90% free memory.
So today I got for me to see if it was still stable, it was not.
After 5 min prime 95 "1344k" I got BSOD (101 vcore) temp was around 65.

The temp is max 60c in games (such as BF3) and never above 70c in prime 95.

Try running 12hours again. Recreate the exact same conditions as to when you did your first 12hour run and if it still fails then yeah we could say it has degraded.

How many times did you run Prime or LinX? I've seen SB systems pass 24 hour prime runs one day and fail within an hour the next. LinX can do the same as well.

I've got a 2500k sitting here at 5.2Ghz with 1.47v loaded, it's been that for 8+ months and it's still perfectly fine and stable. None of my chips have shown signs of degradation and all are running over your voltage.

A few months ago it coul've been colder. My 470 does 987MHz for benches when it's really cold, it barely does 940 normally.
Plus, if it is degraded, it didn't overclock itself to 4.75. tongue.gif

I said deal with it because I myself have experianced it first hand... Althouh it does not bother me anymore (it did at first till I realized my chips potential) everyone wants more speed less volts but only a RANDOM SELECT FEW win the lottery.. If your chip is stable one day tommorow it might not be even if it's set to 1.3v at 4.5ghz it's called "settling in" as munaim told me when I asked him about it!

anyway now that it has degraded maybe you should check your max multi hell i think you should add that to the spredsheat mun see what everyones max multis are!!!

As you can see for 200 more mhz to go from 5.4 @ 1.54 i need 5.6 @ 1.64

Lots of people have voltages over 1.4 and speeds over 4.7 GHZ and their chips are running fine. so i don't believe that your chip have degraded
