AMD Ryzen 4 DIMM RAM 3600 mhz Problem..

[raphaelxd]

Hello friends, I have 4 GSKIL F5-6400 - TZ5RK ram with a total of 4x32GB = 128GB, my processor is Ryzen 7950x3D,
My motherboard model is Asus TUF x670e Pro model. The computer works without any problems with two slots of RAM,
but when I insert 4 slots, the RAMs run at 3600mhz and the PC boots very late.
The latest version of the bios is 2024-11-10. What settings can I make to adjust this? Your help is requested.

I suggest for a first step: leave XMP/EXPO enabled and try say... 5200.

You'll never hit 6400, but see hopefully you can get better than 3600.

You won’t get 4 DIMMs of DDR5 working at high speed unless your name is Buildzoid or you have access to the very best quality motherboard, CPU and RAM.

I’d suggest that if you want/need 128gigs of RAM at 6000 to 6400 speed, you sell your current RAM and get a 2 DIMM pack of Hynix M die which is easier to run since it puts less stress on the IMC of the CPU.

Yes, the motherboard manufacturer mislead you and yes, it would be better if all/most DDR5 motherboards came with 2 DIMM slots but that would put people off since marketing is a thing.

I can list some 128gig kits that Buildzoid recommends if you want?

Edit; you could try manually overclocking the RAM with 4 DIMMs but it’ll take ages to get to a reliable POST and complete memory tests to ensure stability and prevent data corruption.

Courtesy of Buildzoids post over on Patreon - he doesn’t list 128gig kits though so I’ll see what I can find.

“The best memory chips are.
Hynix 16Gb A-die: Speeds of 8000Mbps and higher are possible if your CPU/mobo are good enough. Similar timings to 16Gb M-die

Hynix 16Gb M-die: Tends to max out between 7200 and 7600Mbps similar timings to 16Gb A-die

Hynix 24Gb M-die: Even higher clocking than 16Gb A-die. Slightly looser timings

2x48GB ===============================================

G.Skill Ripjaws S5 96 GB (2 x 48 GB) DDR5-5600 CL40 Memory (F5-5600J4040D48GX2-RS5K) - ************
//Should be Hynix 24Gb M-die. Might also be Micron.

G.Skill Trident Z RGB 96 GB (2 x 48 GB) DDR5-6400 CL32 Memory (F5-6400J3239F48GX2-TZ5RK) - ************
// has to be Hynix 24Gb M-die. Should be a strong overclocker. Might also work at 6000 on Ryzen.

I have 0 experience with quad rank DDR5 setups(4x32 and 4x48GB) and don't recommend them since they put way too much load on the memory controller.”

If you absolutely need 128gigs of RAM, I would suggest sending him a tweet over on Twitter and asking him if he has a kit he can recommend.

I can’t find anything on his Patreon page for 128gig kits.

He has a nice RAM buying guide for the 9800X3D though.

I will research what you wrote, but we are currently focusing on evaluating the kits we bought, I opened a topic on all forum sites, let's see if I find a solution, I will share it with you, because there are some solutions.
