4 sticks of DDR5 7200, which motherboard would support these?

Hi guys,

Haven't build my own PC for a while and ran into a RAM issue.

My Gigabyte X870 GAMING X WIFI7 motherboard has initially booted into BIOS with four sticks of RAM (G.Skill Trident Z5 Neo RGB, DDR5, 32 GB, 7200MHz, CL34 (F5-7200J3445G16GX2-TZ5NR)) but after enabling the EXPO/XMP profile it wouldn't boot again. I have reset the CMOS and tried everything but it will now not boot with 4 sticks of RAM. I have tried all the individual RAM sticks in different configurations and all of them work but only if I use 1 channel (2 sticks). So now everything works fine at 7200Mhz, but I only have 32Gb of RAM.

As I can't get this motherboard to work with all four sticks I started looking into this question but I am struggling to find any motherboards able to take all 4 sticks at 7200Mhz... I found MSI MAG X870 Tomahawk Wifi which seems to support 4 sticks up to 6400Mhz, is this the best I can hope for?

The Ryzen 7000/9000 CPUs can run the RAM in a different mode (not 1:1) which can allow you to hit higher clocks (that would be necessary for 7200, even with 2 sticks).

Officially, a Ryzen 9000 CPU only supports running the RAM at 3600 with 4 sticks, but I'm pretty sure 4 single rank sticks can do a lot better than that. 6400 seems pretty high though, I haven't seen anyone on the forums running 4 sticks at 6400.

Just to clarify, the current motherboard works OK with 2 sticks at 7200 but I was hoping using 4 sticks at 7200...

P.S. I've got the Ryzen 9800X3D

Yeah, to be clear: I suspect it is not possible, regardless of the motherboard.

Thank you!

Any pointers on how it's possible that my current MB booted up with the 4 sticks for the first time and now doesn't?

Any time I put in all 4 sticks the RAM error led lights on the MB.

You might need to try and force enable the full memory training process again. What was the memory running at before you enabled EXPO? I expect it was very slow.

Clearing the CMOS can be a bit hit and miss sometimes.

If you get the memory training to start, it could take some time before it posts (like 5+ minutes).
