Overclocking the Z590 Motherboards

Thanks guys, is this better

Attachment 344190

I should have said I couldn't find any low profile ram with equal timings.

Hi,
On most memory an easy improvement is lowering tRFC as much as possible, 350-500 or until you can't post and then add another 25 or so for stability. hynix kits are more limited than b-die kits here
Then double tREFI to what ever it shows or just set to 40000 max is 65535

Thanks, same as these in my Z590?

Hi,
Yeah that's one of the settings.
Should have a few settings showing the other in bios\
Here's what I set them to.
You might not be able to go that low
Start at 500 on all three instead of 880 is where auto is throwing them that's crazy high and you loose performance on that.

DRAM REF Cycle Time [350]
DRAM REF Cycle Time 2 [350]
DRAM REF Cycle Time 4 [350]

Here is mine....but I'm always tweaking it... LoL

Hi,
You do all three the same setting 350 ?
x299 only has one tRFC setting not three like these z boards have lol

Hi,
z390 or z490 or z590 all are z boards to me
