Sorry if this isnt the right place for this but I found a similar post on here that couldnt help. I recently got 2 extra ram sticks exact same as last time because I figured why not and finish my build yknow. So I put in these two sticks and it wont boot I go bios I reset it to default then it boots but now my memory speed is 4200MT the speed on the sticks are built to go 6400MT. So I tried both the XMP (XMP1, XMP2) I tried manual and setting the speed to 6400MT. It wouldnt boot. I went one by one down on only the light named ones till I got to 5000MT and gave up and reset my bios back to default so it could atleast be used. Is there a way for me to get all my ram sticks up to 6400 speed? Or just take my losses

yup that is what happens when you use 4 sticks, your memory controller on the cpu isnt strong enough. try upping the soc voltage a tiny bit like miniscule bit, maybe youll stabilise higher hz.
DDR5 is *very* finnicky at higher speeds with more than 2 sticks due to signal interference between DIMMs on the same channel. Similar reason to why there’s such a big focus on slots 2/4 when installing DDR5. It is a little odd that your hardware wasn’t able to handle 5200 at least; your motherboard is one of the nicer options for handling higher speed ram on that generation of chip; though both are only 2 years into the ddr5 lifespan. Try loosening your timings a bit and double checking your voltage to make sure you’re not accidentally trying to run them underpowered. Also make sure your BIOS is fully up to date. If these don’t work, 4000-4800 might be where you need to sit — alternately exchanging for 2x64GB (if possible) might be the way to go. Your board should support that size of DIMM on the newest BIOS.
If you want to use that much ram you need a server quad channel CPU. They should have never put 4 slots on consumer ddr5 boards because it doesn’t work.
Yeah, that’s normal. Welcome to DDR5
No chance you can get 6400Mhz on 4 sticks.. try 4800Mhz if that’s stable give 5200Mhz a try.
My CPU was unlucky and could only do 4 sticks at ddr5-4400. I ended up returning that and just did 2 x DDR5-6000.
