Overclocking CPU core temps intel g3258.

[Holystrength]

New OCer here and I have a question about how close should core temps be relative to each other in overclocking? On my intel g3258 dual core I've been attempting 4.5ghz to 4.8ghz and on all the tries I've done 1 core is always between 8c to 9c higher than the other. Is this normal or is it a thermal paste issue? And if it is a thermal paste issue what would be the best way to correct it? reapply or simply add more? Thanks for help and tips.

It could be normal. That one core may just be a dud...which is why partial core-overclocking can often yield much higher overclocks. 

 

Reapply, you can't just readd paste. You could always try reapplying and seeing how the temps look, and if they're the same or similar, but more than likely its just a "bad*" core.

Thsi is pretty standard. The quality of the cores differs, and so the temperature.

So partial core-overclocking is this say just lowering the Ghz on 1 specific core to keep temps in check im guessing? or not even overclock it at all? Does it affect system stability any if you partially overclock?

You're fine man

that cpu boost, it will boost one core clock faster then the other.

Its basically something you do if you know that you're only going to be utilizing some of the cores. 

 

For example, I have a quad core cpu, and I know that the only demanding program I use uses two cores. Therefore, overclocking more than two cores yields absolutely no benefit. But, with a dual core cpu--and with more modern programs--thats not really a good idea. You're better off getting the highest stable oc you can get on both cores.

Alright this is what I'll do.

 

Whats the highest temps I should go for on the CPU when overclocking? Also this chip is most likely only going to last me til broadwell or I might potentially wait to skylake when i'll upgrade to a quad core.

75-80°C

75-80°C

 

Alright I'll shoot for that. Thanks for the help and tips forum friends!!!

You can aim up to 10°C higher, but remember:

 

It's not the temperatures that kill, but the voltage.

 

Example:

 

Lets say we have 2 identical CPUs, both at 4.5GHz.

The first runs at 90°C but at 1.25V.

The second runs cooler at 85°C but at 1.30V.

 

You would think that the second would last longer because it is cooler but actually the first one would actually.

Silicone deterioration is caused by higher voltages.
