Per core Overclock?

[marcvidaal]

SOLVED: I have an i5-9600K and a Gigabyte Designare Z390 (i know the motherboard is overkill, but was one of the only ones that had Hakintosh and thunderbolt support) I have seen in a lot of forums that this model of CPU can reach 5.1 all cores in some cases, but mine can't, well i can't all cores. I did some testings with the Intel extreme utility and prime95 and I came to the conclusion that at 1.360v which i know its a bit high, but I'm fine with that, it can do core 1 and 3 @5.14 GHz, core 2 and 6 @5.04 GHz , core 5 @4.94 GHz and core 3 @4.84 GHz (the core reference speed is set to 100.9 GHz). And when I apply this configuration to the motherboard BIOS I saves but when I open HWinfo it always tells me that all cores are ruining at the lowest core speed (in this case 4.84 GHz) and that the core voltage is not always at 1.360v but if fluctuates with spikes that can reach up to 1.460v (this when i tested all cores @5.14GHz). Does someone know why and how to solve this? Because when i check in the BIOS the changes I made are still there. (no AVX offset is applied)

As far as I know, it's not possible to set a core-specific overclock. Generally Intel platforms allow to define how much is the multiplier is when 1-core is being loaded, 2-cores, 3-cores etc. Show your BIOS settings.

has to be possible cuz my CPU came from intel with different clock speeds, take a look at the bios default row

As mentioned these lines are what they say, "ratio when 3 cores are active", not "ratio of core 3", which is why the more cores are active the lower the ratio.

okay now i understand
