X670E ASUS TUF not working with 4 sticks of RAM

[icharles_ou]

System :

CPU : Ryzen 7900x
Motherboard : X670E TUF ASUS
RAM: 4x 16 GB G skill Trident Z NEO 6000 mhz CL36 ( 2x different kits but same specs )
PSU : CORSAIR X850
GPU: RX 6800 XT
AIO cooler : Masterliquid M360L
Case : Lian LI III

Problem : When I put all 4 sticks ( following the right order ) , the computer wont display any signal on the monitor.
But if I use just Dual channel or 1x stick , it will load fine.

I tested all sticks and they are healthy , the problem is when I put all of them togheter.

It is weird to think they are incompatible as they are from the same seller, brand and specs.

Any thoughts?

Hey there,

The only way to find out is to try acquiring the same type of kits and test.

There's nothing currently on the QVL for a 4 stick configuration; only 1 and 2 stick configurations are listed. (That's the "socket support" column of the QVL.) With DDR5 being very new, that may well change over time, as the manufacturing matures.

4 stick overclocked configurations are harder to support than 2 stick. E.g. going back to X570/X570S boards, it's easy to find DDR4-3600 which works as a 4 stick configuration, but faster than that is only listed as supported in 2 stick configs.

( 2x different kits but same specs )....

That the caused. Even same mode with same spec may not come out from the same batch, same production line and assembly . And did not tested or certified running in QUAD.

In order to run 4 stick RAM or occupied 4 slot of RAM. You need the RAM set certified as Quad pair (4X of ram in the same package) with Asus QVL.
