One of my cores seems to be acting up on my 4790k

Hello Community,

I've noticed that one of my cores seems to update slower than the others when viewing their activity in MSI Command Center software...

When I first launch MSI command center software my cpu is overclocked to 4.4ghz... But the actually real-time speeds of each core are displayed... all moving around about 4.300ghz to 4.400ghz except for the last core listed as core 3 (the 4th core, it counts 0 as the first core.) the last core sits at 4.000ghz with no fluxuation for like 15 seconds then it seems to activate and jumps up to the levels of the rest of the cores...

Even after the last core catches up (starts working) it updates slower in real time than the rest of the cores... the other cores will be jumping around from like 4.326ghz then 4.352ghz then another value around there all within a second or two... but the last core will only show a real time speed every 3 seconds or so, updating and showing different real time values and a different rate than the rest of the cores.

I hope that makes sense, it's the best I can describe it.

In the past few years I've shipped my computer overseas a couple times... both times I had issues with booting the computer up the first time on shipping. first time it wouldn't turn on I brought it to a PC repair shop and the awesome guy figured out that it just came loose and the cpu needed to be tightened down... when I shipped it the second time it wouldn't turn on again so I try reseating the CPU, cleaning it off and putting new thermal paste on it... it still wouldn't turn on. After unplugging a bunch of the power cables from mobo to various components finally something worked and the PC booted up and it has, as far as I can tell been running fine.

How can I check to make sure all my cores are ok? Is it possible I damaged one of the cores from shipping or reseating the CPU?

Thanks community :)


 
Solution
You could test it at stock settings with prime 95. If that one core fails at stock settings then I suppose there might be something wrong with it. Use cpuid to monitor while testing. As well as small fft for the test.
