CPU Overclock core being useless? XD

[mattonfire]

Hiya I have 2 questions:

1. Why are two of the core temps completely different to the others - I hear that RealTemp plucks the temps right from the CPU itself so I doubt there is a problem with the software.

2. The CPU is a i5 4690k - It is currently set to 4.2Ghz with no voltage increase but as you can see from the picture it's hitting a max of 78 celcius under max load from Prime95. Should I increase voltage at this point to attempt to lower temps, if so what about? 1.1?

Increasing voltage increases heat.

Okay, sorry. Must've listened wrong in the video then. Are those temps okay for stress load? + What about those cores?

If all four cores were stressed at the same time it's not normal for one core to max out at 77°C and another to max out at 55°C. I'd double check your CPU cooler and make sure it's mounted properly. Also make sure Prime95 is stressing all cores and not just two.

Well, it was fine for the other stresses. Here have a look at the tests. Should I run the test again to see?

you will never have any load that will be even close to prime 95 so you are fine

Alrighty, what about the strange temps though?

because intel uses shit thermal paste

It's not a stock cooler ahaha, It's the NH-D15S. And retested it and they are all within 1/2 of each other, think the test was just poor.

It seems suddenly you're getting an irregular result at 4.2GHz but the rest appear fine.

Run the test again at 4.2GHz. If it is still weird run the test at 4.1GHz. If that result is fine set the voltage a little higher and set it back to 4.2GHz and run the test again. You may have reached the limit before more power is required.

Yeah, redid the test. It was absolutely fine.

i mean between the cpu silicon and the metal plate you see on the top of the cpu

Yeah, the thermal paste came with the cooler. Not from intel  Noctua

the metal part of your cpu where you put YOUR thermal paste is NOT the cpu silicon, intel puts shit thermal paste between the SILICON (cpu itself) and the metal where You put your thermal paste

He's talking about the compound between the CPU Die and the heatspreader, not the heat spreader and your cooler.

Ohh, I think I know what you're talking about now. I'm pretty sure I saw a video of someone changing it. They had to take the glue off and got messy.

Yea it also voids the warrenty.
