Early tRAS re-testing results
I've kinda mentioned that I want/need to retest tRAS on AM5 in a few videos livestreams. Well I've finally started on that. Here's the results I've gathered so from dual rank testing: LOOK AT THE ATTACHED PNGI also have data for SR but it's a mess and unfortunately I'm curren...

Ryzen AM5 Hynix 16Gb M-die DDR5 timings 2x16GB/2x32GB DDR5-6000 to DDR5-6400 V0.1
An expanded version of the original "easy Hynix timings". 16Gb M-die generally doesn't clock past 7000ish so all the settings here are for 1:1 mode since 2:1 mode at less tha 7600 doesn't perform well.
Ryzen AM5 Hynix 24Gb M-die DDR5 timings 2x24GB/2x48GB DDR5-6000 to DDR5-8000 V0.2
This is a more comprehensive version of the easy Hynix DDR5 timings but specifically for 24Gb M-die. Also include dual rank timings which the original easy Hynix timings didn't.V0.3 improves tRAS and tRC settings.
Ryzen AM5 Hynix 16Gb A-die DDR5 timings 2x16GB/2x32GB DDR5-6000 to DDR5-8000 V0.4
This is a more comprehensive version of the easy Hynix DDR5 timings but specifically for 16Gb A-die. Also include dual rank timings which the original easy Hynix timings didn't.EDIT: V0.2 added some even looser timing to try if you can't get certain speeds to work with your XMP/EXPO defaults...
My personal AM5 DDR5-8000 success list
This list isn't meant to be an absolute "quality" ranking as the timings aren't being accounted for and some combinations may have had more effort put into them than others.Also I am almost certainly not going to test every possible combination. I don't really have the time or re...

Why raising tREFI or lowering tRFC has diminshing returns on performance
This recently came up on the AHOC discord but I'm pretty sure I've mentioned this in a video or something but anyway:As tRFC ÷ tREFI approaches 0 further reductions in tRFC or increases in tREFI will impact performance less and less.tREFI increasing:800tRFC with 8 000 tREFI = 10% of clock c...
