Question I'm trying to lower my RAM latency ?

[Vetrix1996]

On AIDA64 its 69ns. Any tips to improve it? I've got Hynix A Die DDR5:

Update your post to include full system hardware specs and OS information.

Include PSU: make, model, wattage, age, condition (original to build, new, refurbished, used)?

Disk drive(s): make, model, capacity, how full?

That's not terrible, I mean things aren't really any better on team blue

But when you consider that 18 years ago without even an onboard memory controller and with the RAM running at stock speed got this, well it explains why CPUs have so much cache nowadays.

The common theme seems to be you need a lot of memory voltage to greatly reduce latency on 9000 series. Both of the following are from the big AIDA64 thread, with 9800X3D and Hynix memory:

This fellow did the buildzoid DDR5 tweaks intended for Hynix memory on 7000 series CPUs and was disappointed at DDR5-6000

Raising the memory voltage by quite a lot allows tightening some strange timings considerably, set like so:

In many cases setting the command rate to 1T like these have will require slacker timings or slower speeds that may decrease overall performance, unless you are really willing to blast in the voltage. And this is despite the 9000 series still having GearDownMode so the 1T setting can be more like 1.5T. If you want to stay at 1.35v you may want to experiment with 2T + higher speeds
