Intel to AMD upgrade, re-using 2x24Gb memory?

exm · 2025-03-18T03:05:11+0000

Currently I am running a z790 with the Intel i7 14700k processor. I am expecting my 5090 this week, which means a new PSU, which means.. Why not, let’s upgrade the processor+mobo also. But I have a few questions:
- I am running the TeamGroup T-Create Expert 48GB Kit (2 x 24GB) in my Intel setup:
* DDR5-7200 PC5-57600
* CAS Latency 34, Timings 34-42-42-84
From what I learned, AMD really prefers 6000-30 RAM. The memory does not have the Expo profile but I read from a review on Amazon that a user has great luck with this kit and a 7800x3D. Any thoughts on using this RAM? 48Gb is really the sweet spot for me.
- I am planning to get the ASRock X870E Nova WiFi motherboard (I have the Riptide for my Intel and I like ASRock). Any thoughts?

You can just run a custom speed of 6000+ with custom timings if you're interested.

Will summon @ir_cow for you

6000 or 6400 at the best and make sure that bios is updated for better compatibility

6400@CL30 is good but 6000@CL28 is the holy grail. 6000 being the sweet spot and CL28 being low latency

You can check on the motherboard vendor's site if the ram is compatible. It should work fine though. Bios update might be necessary.

Not if you already have a decent set of ram it ain't.

That kit is Hynix M-die. One of the best kits for ryzen. Just underclock it to 6000-6400 depending on how good your imc is and tighten up a few timings. At 6000 using xmp voktage that kit should run cl28-rcd35-rp35 without problems. Just set trfc to 500 and trefi to 50000 and you get a great deal
