Prime95 and slower hotter core

post #1 of 3
Thread Starter 
Well I have been trying to up the OC on my CPU, I would bump up the multiplier and voltage slightly... got it to 4.8 Ghz with 1.41V....I ran prime95 torture for a couple of hours and used coretemp to monitor the usage and temps.... The temps hovered around mid to high 60s except for core 1 which wanted to stay at low to mid 70s..... after hours of running prime. I also observed that 3 of the cores were running this same test number, while core 1 was still running tests, but was behind by 5 as compared to the other cores...

I think core 1 is faulty and is causing the computer freezes I have been experiencing(infrequently mind you)...it is annoying to play a game and suddenly having to reboot the computer...

What do the rest of you think?? I am debating on upgrading to a 2600k anyway, but if I have to replace my cpu, I would rather not resell a possible faulty 2500K by mistake...

its not faulty by any means. A lot of CPUs have a "slower core" and some require more voltage than the others to stabilize the cpu. You just have to raise the voltage or lower you clock to 4.7 and get a stable voltage there if you want to keep it at a low voltage. Two of my cores run hotter than the other 2, its nothing to worry about, its pretty common. As for resale value, there is nothing wrong with the CPU at stock, correct?

I haven't ran it at stock since I put this rig together....I will try more voltage and downing the multiplier to see if that helps.... still debating on getting a 2600K in anticipation of the Chimp challenge this month
