Hey there, I see you're dealing with a tricky RAM setup. Your system seems to work at 4000MHz with only two slots filled, but it struggles when all four are used. The error message drops and then restarts to 2133MHz, which might be the issue. You've tried different RAM kits and even swapped out your motherboard or CPU, so you're pretty sure it's not those parts. The RAM model you have is a Ryzen 7 5800X with G.SKILL kits, and you mentioned specific product links. Are there any other components you suspect might be causing the problem? Your help would mean a lot!

Running at 4000MHz across four channels is quite challenging, particularly in a 1:1 setup. A 1900:1 ratio would be more manageable.

It's typical to see such performance. The high-speed RAM paired with multiple sticks per channel really pushes the memory controller, making it tough to maintain those speeds. The board configuration could work, but it's probably not feasible.

Filling all four slots presents a challenge for RAM under overclocking, as the listed speed is actually an overclocked figure. The situation gets worse with two separate kits that haven’t been verified to function well together when overclocked. Just adjust timing settings and raise DRAM/SOC voltage (if you’re confident), or lower the memory speed until it stabilizes.

Review the MOBI list for your board. The C16 isn’t shown, but compatible timings are available for C18 and C19 sticks at 4000.

It supports a 1:1 match from 1933 to 3866 using DOCP, and 1900 without it.

It's simpler to use one rank configuration at full speed rather than a dual-rank setup. Ryzen doesn't depend on the number of sticks, and it doesn't cause stress. Running dual ranks on two sticks gives comparable performance, so it doesn't significantly improve over using four sticks. For the sake of it, I'm testing two different configurations.

The 4000MHz specification applies to individual components, not combined sets. Without DOCP it will produce poor timing and lower voltage—leave it enabled.
