Question CPU not reaching max clock speed 4/4.2gh

[xXAhmad10000Xx]

ok so first thing to say that i had issue with my old motherboard so i had to change it and got

so ya whatever i do it wont reach 4.2gh which is max i heared a thing or to about enabling multi core on bios but the only thing i can change it to is asus mode and off. there is no "on" / "Enabled"

i didint too much to be honest like i just overclock thro bios and using quickCPU app only.

last thing to say am afraid to say this but.. could it be that my motherboard support 4gh max only?

The listed turbo boost speed of 4.2 GHz is for light workloads (1-2 cores) only. Putting a workload on the all of the cores won't allow it to reach that speed due to power constraints.

...am not sure what u mean but it was working fine with old motherboard also does that mean should i disable multitheread core ? or keep it on am not really sure what to do xd...

enabling multi core on bios

The F series CPUs have a locked multiplier. Only the K series CPUs are unlocked and support a multi core overclock. Your previous motherboard must have been magic if it allowed an all core overclock on a F series CPU. There might have been an option in the BIOS for this but it probably did not work or do anything.

The short of it is, you don't have a problem. The processor is working as expected.

But if you want more info:

• All processors have a power limit. In this case, your processor has a power limit of 65W.
  • Note that the processor has things other than the CPU cores and the power limit includes everything.
• You can think of this power limit like a bucket of how much energy the processor can allocate to each part of the processor
• It takes more power to increase the clock speed of a core
• For the sake of simplicity, lets say there's 60W to go around for the cores
• At the maximum clock speed listed, a core may need something like 25W
  • So if you have one or two cores that can do the work, there's enough power in the budget to push them to their fullest clock speed
  • However, the moment you add work on a third core, the total power needed to get those cores to the fastest speed is now 75W, which exceeds the limit of the processor. Since the budget is 60W, each core can only get 20W, which lowers how fast they can go.
  • And then if you add work on the fourth one, now every core can only get 15W

This is why you can't have the listed turbo boost on all of the cores.

I'm not sure what you mean by "disable multithread core", but the closest thing I can think of since you mentioned an ASUS board is "Multi Core Enhancement." This tries to bypass the power limit so each core can boost to the fullest regardless of how much load is on them. Though I'm not sure if this works on i3s or non-K processors.

In short the CPU will only turbo to that speed 4.2 when it needs the extra boost. It's normal speed is all core speed is 3.6.

alr ty guys ill try to stress test and see if it hit 4.2

yes that what i ment, the old mother board had a feature called (core boost / ddr boost) i guess thats why i got 4.2 on em

B365M PRO-VH

so at the end u think i can get the 4.2 to work or just quit trying

i mean the 0.2 seems w for heavy cpu game like COD
speically on my setup which is i think bottleneck i use that cpu with gtx 1650​

ill give it a try stress test
