Ram cant reach its targeted speed.

[TaxiVromVrom]

Finished my build with Asus Prime Pro, Ryzen 5 5600x and Crucial Ballistix 2x8gb 3600mhz.

 

So the issue is while running XMP above 3400mhz the MOBO wont post while without it the ram is visible as a single channel and not dual channel.

The motherboard is running the newest bios and I have no stability issues its just the ram that cannot hit its marketed speeds.

 

From what it looks like after some tweaking the cpu is running fine 4.6ghz under stress.

Ram: BL2K8G36C16U4W

What happens if you manually key in the timings and speed? Some boards and ram combos just don't like xmp, but are perfectly happy when manually input.

Then the ram doesn't run in dual channel for some reason even if they are in correct slots. But yes 3600 runs when I do it manually.

Have you tried clearing CMOS and reseating the RAM?

 

Otherwise, the 5600X is only rated for DDR4-3200. Everything over that is considered overclocking. Most Ryzen 5000 chips can do 3600 no problem, but it's not guaranteed. It could be that you lost the silicon lottery and the memory controller on the CPU just can't handle more than 3400.
