I just found out I had the timings incorrect: 22-24-24-42 if I remember correctly. Set it on 16-18-18-36 and I feel like it performs a lot better. But the command rate is on 2N even though my RAM supports 2T. When I type 2T it goes back to 2N. How can I fix it and does it make any difference?

 

Asrock B460M Pro4 (P1.50)

HyperX Fury RGB 3200 2x8 (clocked at 2666 due to CPU)

i5-10400F

Sapphire Pulse RX 5500 XT 4gb

Some memory is just better on a 2T command rate. It does not impact performance enough to worry about it. 

My ram kit is rated at 3200 but only lets me set it to 2666 my command rate is stuck on 2N, when i try to change it to 2T as said on Cpu z it goes back to 2N could that be holding the speed back? also i can’t find any xmp setting in my bios its simply not there.

2T and 2N is nearly the same thing. No worries there.

No, I don't think that command rate is holding back the frequency.

 

I would need to know specifically the rigs hardware specs, or we'd be just guessing.

What CPU and motherboard? If Intel you will need B560, H570, Z590 or Z490 to run higher than CPU limit. If you have an i5 or lower on 400 board not Z490, then it will be limited to 2666, if you have an i7 or i9 on a 400 board not Z490 it will run at 2933.

command rate 1 vs 2.

i have an old oem board, bios is very limited.

when i run 2x8gb i get a command rate of 1
any more than 2 sticks i get command rate of 2.

essentially, every memory operation will have +1 onto every timing.
This is for stability to avoid BSODs.
on some boards, more sticks = lower max clock.

command rate of 2 is negligible and would only manifest as a -1% to -2% loss in a synthetic benchmark.
