So I have Asus STRIX z370E Gaming motherboard. With that CPU. I have a few questions before we get to the overclock.

1) Will OC disable its turbo boost? (Do I really need it when I OC?)
2) Voltage (After we determine it, can I set it to adaptive or something, so if CPU is not really working a lot it doesnt draw much power?
3) How long can it last with the overclock?

I want a mild OC @ 4.7GHz so since that is easy I just need you guys to help me out a bit.

1) Well you could disable turbo boost and just set the base clock as your max clock and keep it there, I wouldn't do that personally. I would just increase the multiplier which increases how far the CPU will turbo, x49 for example would be a turbo of 4.9ghz. I like to allow my CPU to lower it's clocks at idle, I see no reason to run say 4.9ghz at all times, its a waste of energy.

2) Yes, I use adaptive. Again I see no reason to push a lot of voltage into the CPU at all times even when it does not require it.

3) Assuming you keep it cool and don't overvolt the hell out of it in terms of core voltage, DRAM voltage, VCCSA voltage, etc. It should last as long as it would at stock clocks. The CPU will likely be obsolete before it ever...

Hi Evvvvv,

1°/ As long as C-States and EIST are enabled, and CPU ration is not in "fixed mode", the frequency will fluctuate with the load.
2°/ First you find the minimum voltage needed for a given frequency using a fixed voltage. Then go with adaptative to let it change with the load.
3°/ 4.7GHz is the frequency of it's own boost with turbboost feature so it should last as long as needed.
It should last until an upgarde is necessary.


Rodolphe.

The CPU will turbo to 4.7ghz on a few cores by at stock. You can turn on multi core enhancement which will turbo all cores to 4.7ghz when under load if you want to stay at 4.7ghz, that may improve performance slightly in some applications. I would try maybe 4.9ghz and wee what voltage is required to get there. For stress testing I would recommend something without AVX if this is a gaming PC, prime95 version 26.6 for example, or a CPU heavy benchmark of some kind.

Okay lets see if I understand. My memory is already on its XMP. I put CPU Core ratio at SYNC ALL CORES. Adjust multiplier at 49, set CPU Core voltage on something to see how stable it goes. If stable, put it back to 4.7GHz and set voltage on adaptive, around that fixed voltage?

Evvvvv,

What he says is that you could try to go to 4.9 because 4.7 is not really an overcclock because it's the boost frequency with the "enhanced turbo boost".

Once you get the fixed voltage needed for a given frequency, you can make it adaptative for THAT frequency.

Alright, so my last question is, only thing that I change is I put that boost to sync for all cores? its not just one core that will boost to it? (if you know what I mean)
