x4 Dimms X570 Board

Hi all,

Likely an easy question for most.

Currently have a Gigabyte Auros Pro with x2 dimms 16gb. Looks like the new MS flight sim with maxed out textures is going to need more ram.

I've currently got the below and was thinking of buying the same again, but i recall seeing somewhere s that x4 dimms can clock it back a bit?

Cheers in advance.

Most motherboards have "daisy chain" DIMM slot wiring, which is better for signaling with two DIMMs.
But Zen2's memory controller should be good enough to make that matter only when looking for high memory clocks.

That's very expensive 2x8GB kit...
There are 2x16GB kits for the same:

I've just bought another 2X8 GB for my rig for Flight Sim when it finally comes.

I've actually read that 4x8GB can give better performance than 2x8GB on Ryzen. Will let you know..although I run my memory at XMP settings with tighter secondaries.

If you've got single rank DIMMS then using 4 slots is usually OK. Most 8GB modules are single rank, CPUz will tell you what your modules are in the memory tab.

Trying to run 4 dual rank modules at a good speed is more of a challenge.

That's because command interleaving of two ranks per channel helps in many real world workloads which have multiple memory accesses going on:

16GB dual rank DIMMs behave same.

I run 4x8GB no issues on X570. I have a 3600C16 kit and 3600C17 in there. If I enable XMP both kits run at C16 no issues, and I can still OC the ram.

Im running 4 x 8gb sticks of G.Skill Trident Z Royal Silver CL18 at 3600mhz, it will overclock to 3800mhz at stock timings too, runs perfectly fine on an MSI X570 ACE, however my 3900X has just started to play up and im about to RMA it, will be setting up a thread later today, just running some tests.

X570 Taichi
4 x Patriot Viper Steel 8Gb 4400 (Dual rank)
Running at 3600 14.14.14.28.46 1T

I also upgraded to 32 Gb with MSFS in mind.

Well I'm struggling with 4 dimms. See the 8pack ram thread.
