1. What is the temperature of the CPU during normal usage when the core count is doubled, compared to setting the correct core count?
2. Does the CPU run hot?
3. What type of thermal solution are you using, AMD stock fan/heatsink, All-in one cooler, large third party heatsink and fan(s)?
4. Are the CPU fan(s) working harder to keep it cool?

@jan001232 do you have changed only cores count in your config.plist (doubling it i mean)?

 

[Edhawk]

If you notice the CPU temps creeping up over time, you might want to think about adding a second fan to the CPU tower cooler. So you have two fans with the push and pull action, i.e. one either side working in tandem to dissipate the heat from the aluminium heatsink.

So I have to set to 20?
I have a 7950x (16c -16 t)

 

[Edhawk]

Wouldn’t 32 be more logical?

 

[mariettosun]

20 means 32 c

@jan001232
time ago we discover it was possible to boot AMD cpu with multiple numbers of core than the real numbers
never tested in this way for benchmarks
here my results





have you tested this with others benchmark like CInebench or geek bench?

 

[mariettosun]

in cinebench similar results (worst with 20 core counts number)

 

[mariettosun]

My cooling system is in my signature (a liquid cooler from artic)
I limit CPU temperature to 83 in my bios settings

 

[mariettosun]

Which one work for sure in osx with hackintosh?

 

[Edhawk]

Perhaps Corsair MP700 ?? (remains to be confirmed)

The Corsair MP700 uses a Phison E5026-E26 NVME controller, so it wouldn't be a good choice for macOS. In fact it is very similar to the Controller used in your Kingston KC3000 2GB drive (Phison's PS5018-E18).

I would recommend the Western Digital Black SN770 or SN850 as a macOS boot drive. Both of these WD (SanDisk) M.2 drives are known to work well with macOS but are only PCIe 4.0. Apple support WD (SanDisk) M.2 PCIe 4.0 controllers in their Intel Mac's.

MacOS doesn't natively support any third-party PCIe 5.0 NVME M.2 controllers, as yet, as none of their Intel systems use PCIe 5.0. It is possible that the next series of M.2 drives released by Western Digital will be supported, but that maybe wishful thinking on my part.

In my case, benchmarking through Geekbench, the effect is opposite. Decreases performance when increasing the number of cores.

Reminds me of using Clover setting the FSB to a stupid number. macOS detected my FX 4300 at 40 something GHz but system was completely unusable. Took 5 mins for finder to launch.
