Question About Memory Clocks

[WASDWASD]

My kit of 2 x 8GB Patriot DDR4-3600 CL17 has been set to its rated speed and voltage in BIOS on my 5600X and ASRock B550 Phantom Gaming 4, but on HWiNFO, it shows a memory clock of 1,796.7 MHz. I know that since it is double data rate, it will appear as half the rated speed. But I'm wondering if the 3.3 MHz difference from 1,800 MHz will affect anything, such as the 1:1 infinity fabric clock which I know is optimal for Ryzen CPUs.

I bet if you look at HWInfo for your FLCK you'll see it fluctuating at the same rate - I wouldn't worry.

Memory clocks aren't like set in stone, they fluctuate a few MHz up and down. .2% variance is almost certainly well within the rated spec range.

According to HWiNFO, my infinity fabric clock is at exactly 1800 MhZ. Although I guess I shouldn't worry since it may fluctuate a bit. Thanks for the help!

well the polling isn't real time so there's that too

im sure someone who is more familiar with Ryzen will come along shortly.
