Hey everyone, I got my Spectrix D80 3600 CL17 running at 14-14-14-28 3600 1.45v. The AIDA scores look off—shouldn’t the latency be lower? Also, Power Down is turned off.

Performance differences show latency tends to be greater for Ryzen compared to Intel.

It seems reasonable to reduce it to 1.4 for me.

Theoretical maximum bandwidth for a 3600MHz memory is 57,600 MB/s, which might make your findings appear modest—perhaps the secondary timing parameters are quite tight. Latency seems to be more typical.

Looks like the signal is weak, but your 3600MHz CL18 model shares comparable delays too. Make sure no background processes are active during testing.

You're right to verify this. It's common knowledge that 1.45V is safe for B-DIE, and even 1.5V works. Your adjustments to the timings and motherboard settings seem to have achieved solid performance—53655MB/s is impressive! Let me know if you need more details.

It would reach its maximum voltage when timing isn't maintained at 1.4, but keep it at 1.45

At 1.4v the MOBO isn't posting. Latency is now 66.6ns with tRC 40 and tRFC 288. Which option—3600 14-14-14-28 or 3733 16-16-16-36—performs better overall?

It depends on the maximum speed of the FCLK

Typically 3600 works better, though a higher frequency needs a higher FCLK (provided the interconnect supports it)
