good & bad news-i7 2600 k degraded

post #1 of 23
Thread Starter 
so i was running this 2600k since more than 5 weeks at 5 ghz-24/7,



first blend result was:

http://s004.radikal.ru/i206/1101/8d/d852f11f1a8b.jpg

followed by some crazy voltage max out prime blend runs above 1.6 volts,
which probably caused the degrade...

http://s44.radikal.ru/i104/1101/12/03383ff0a19c.jpg

-i pumped up to 1.69 volts into the chip...

the next 5 ghz blend session looked like that:

http://s44.radikal.ru/i105/1101/ee/b5912968535e.jpg

and finally today:

http://i038.radikal.ru/1102/df/0f6ab0465a84.jpg

the good news is,hard to destroy these chips...even degraded it does the trick

so,from my point of view i would recommend the following:

stay below 1.5-1.52 volts;

see if it does the 5 ghz...

and stay away from finding out whats the maximum for the chip by applying voltage above

~1.5 v.

***OVERCLOCKING GUIDELINES***

- Do not exceed 1.35-1.38v core voltage, doing so could limit lifespan of the CPU
- Do not overclock with BCLK, again doing so could limit lifespan of the CPU
- Recommended memory voltage is 1.50v, so make sure to run your memory at 1.50v, higher could limit lifespan of the CPU
- These recommendations come from OcUK and Intel, your warranty is un-affected but we highly recommend you adhere to the above to make sure your CPU lifespan is un-affected
- All Sandybridge CPU's worldwide should be run at the above or lower voltages, no higher!

I'm quite sure those were found to be incorrect. More so the CPU VCore and DRAM Voltage than anything.

First off. One hour of Prime95 doesn't mean crap for stability. Try 8+ hours. Second your pumping close to 1.6v on your chip for 24/7...duh it's going to degrade.

1.6 is pretty high in general and crazy for 24/7.

Glad I only need 1.28V to have almost identical performance, that's unfortunate you degraded a wonderful 32nm cpu.

Thread Starter 
no regrets,weeks ago there was much speculation about how much these chips can take.

my chip was crap from the beginning,so i decided to donate it to "science"

only to point out again-it still runs rockstable.


sooner or later i`ll grab a new one-maybe a xeon if they come unlocked.

1.69v for a 2600k? Bad idea even if you've got LN2.
