Ask them about their heatsink choice and how they applied thermal paste etc. Could be their cooling is better and CPU is clocking higher coz of that. Also, do they have four RAM sticks? The IMC could be limiting your clocks due to the load of four sticks.
I will ask about how they did thermal paste. I couldn’t achieve 4550 with 2 sticks of RAM before upgrading to 4 sticks. Was on 2 sticks for about a week. Tried without XMP at just 2133 as well.
For thermal paste, I did a slightly bigger pea sized drop than I usually do. 4550 MHz should only be achievable under lightly threaded tasks I think. Once more than 3 cores are utilized, 4450 should be its max clock speed.
Because of that, I have a feeling thermals are not the issue; but I could be wrong.
I did look into HWiNFO’s Power Reporting Deviation since my motherboard is not accurate OOB. But once I lowered my PPT, TDC, and EDC to some 5800X users, I saw it hovering around 99% under heavy load. I put values back to Auto for time being.
One thing I haven’t figured out in HWiNFO is its Frequency Limit - Global value is 4450 MHz. Not sure if important.
