EXPECTED LATENCY - CL30

[Megatron#59]

Hi,

I’m running an AMD Ryzen 5 7600X with Corsair Dominator 6000 MHz CL30 (16 × 2) EXPO RAM.
What latency should I expect with EXPO enabled, without any BIOS tuning?
Also, after tuning, what latency could be expected?

Additionally, what adjustments or settings would you recommend?

Thanks in advance.

In Aida it's usually somewhere around ~10 ns improvement from stock EXPO vs tuned, I wouldn't put much stock in the actual number though, as it varies from run to run, and motherboard to motherboard.

Buildzoids video here is a good starting point

off top of my head 6000 cl30 on zen4 is about 65ns latency

I tuned the timings exactly as Buildzoid explained in the video and adjusted the tRC based on my tRP and tRAS values (tRP + tRAS = tRC). The timings are quite tight, but the system is running without any crashes so far. I’m getting only 69 ns latency.

you mean on stock or expo or after tuning.
Mine was like stock 81, expo 76, tuning 69.
