AM5 CPU to handle Quad DIMMs w/tweaked timings?

Posted by RegularTech575@reddit | buildapc | View on Reddit | 5 comments

Hello guys!

So I got 128GB of RAM (4 Crucial Pro 32GB 5600CL46) sticks a while back before the market situation peaked (Thank you Steve from Gamers Nexus).

I’m looking to grab a CPU to handle 4 sticks with manual timings without issues. I’m aware DDR5 is more complicated to run with 4 sticks.

The sticks are Micron D-Die so I can tweak the timings a bit to at least 6000MT/s.

What AM5 CPU would be ideal for this? My current parts are: 5070 Ti, Asus X870 Board w/4 RAM slots, 1000W MSI PSU, Thermalright Peerless Assassin 120 SE for CPU and 5 Arctic P14 Max for the case, good airflow.

I don’t want water cooling to avoid running into any issues long term.

Should I get a temporary CPU and wait for the next gen or is there a good option nowadays?

I'll use my PC for Gaming / Local LLMs / VMs / Light video editing, so I'm willing to go high end if there’s a huge benefit there that won’t get any better in the near future.

Any tips or suggestions would be greatly appreciated.

Thanks in advance!

Zen 6 will most likely have a better memory controller but it’s probably not going to come out till next year so you’ll have to wait a while.

With the X3D stuff you can at least feel better about giving up speed for gaming. In gaming the difference between 5200 and 6000 with a X3D chip is unnoticeable.

When trying to run four DDR5 modules there are no guarantees. It might work, it might work at a much slower speed, it might not work at all.

There's no AM5 CPU that's more likely to work than any other. They all use the same memory controller.

Is this a silicon lottery situation?

Yes, with the CPU, motherboard, and RAM.

Ah I see. Thanks for the info! Appreciate it man.
