High Latency for Memory?

Hello Folks,

Just looking for some advice on where to go from here?

I just completed a 7800x3d build and copied some ram timings from Actual Overclocking Tuber, though my latency is ~10ns higher compared to some folks calming they did the same thing.

What can I tighten up here to improve the situation?

You are running AIDA in hypervisor mode. Turn off Core Isolation in Windows.

Microsoft Vulnerable Driver Blocklist: On

Adjusting the following reduced latencies by 1.1 ns.

tRCDWR: 36
tRCDRD: 36
tRP: 36
tRAS: 28

tras doesnt go lower others should be fine at 36

I just set it to 28, and tREFI to 65535, and I got a worse latency, but maybe some background process spiked or something?

66.2 now.
A second run is up to 68.9
Similar for a third run.

Should be able to get around 52-54ns depending on the kit. Mine is around the 52ns range
