i5 2500k unstable chip

post #1 of 5
Thread Starter 
Ive had this chip for a few weeks now & find is ok low voltage, even 4.5ghz @ 1.4v (which is nice) When I start going bigger tho, is when it runs into problems.

For example. I was running 4.8ghz 1.42 with LLC extreme & ran for an hour OCCT. Then I rebooted & it couldnt get past the Windows start up screen.

This happens whenever I try bigger clocks,

5ghz @ 1.52v Will work for hours, but next day will BSOD 101 or not even boot.
4.9ghz @1.5v .............

Im not complaining as 4.5 is a safe speed, but dont get why it does this, far from rock solid like my old AMD 1090t.

Doesn't sound like your chip is stable at all - you should run Prime95 blend for 15+ hours, if it fails before then thats a problem - BSOD 101 means increase vcore, so you have too low of voltage for your chip which is most likely why it can't pass windows at times.

Here is a list of BSOD Codes which can be referenced from OCN -

BSOD Codes
0x101 = increase vcore
0x124 = increase/decrease vcore or QPI/VTT...have to test to see which one it is
0x0A = unstable RAM/IMC, increase QPI first, if that doesn't work increase vcore
0x1E = increase vcore
0x3B = increase vcore
0xD1 = QPI/VTT, increase/decrease as necessary
0x9C = QPI/VTT most likely, but increasing vcore has helped in some instances
0x50 = RAM timings/Frequency or uncore multi unstable, increase RAM voltage or adjust QPI/VTT, or lower uncore if you're higher than 2x
0x116 = Low IOH (NB) voltage, GPU issue (most common when running multi-GPU/overclocking GPU)
0X109 = Not enough or too Much memory voltage

Some of them are more specifically for 1366 processors, but most of them generally apply (such as your 101 code) to every processor.

Yea I knew 101 was vcore. This is what I am saying, even with LLC extreme which fluctuates massively anyway it BSOD.

correction: shows @ 1.3-1.4 when stressing (set on auto in BIOS), which I doubt will degrade my chip was my point, but yes this is far from a golden chip lol 1.52 with LLC on extreme & it struggles @ 5ghz, with full water, not running over 70c.
Im pondering on selling & grabbing an i7 2600k. Seeing if I get a better chip.

I've built a SB system and I know that the 2500k in that was nowhere near the best, but I managed 4.5ghz @ 1.315 vcore and it was over 48 hours prime95 blend stable. To reach 4.8ghz I needed 1.45v and that was also +31 hours p95 blend stable. You're using 1.4v for 4.5ghz? Either your settings aren't efficient or you have a seriously bad chip.

yeah your chip sucks...
it can be stable, but it is not a good OC'er...
back it down to 4.5 or even 4.4 if you can go sub 1.4v on it.
