Recommended Posts

Hi a got an

Aorus Ultra x570 mother board

a Ryzen9 5950x

and 4x16Rb of corsair LPX 3000 modules CMK32GX4M2B3000C15


i buy them as two separate items 2 modules then the others two but the same type


i want to make this modules to run at 3000mhz but i cant make it

i set the xmp with the auto profile 1 which shows the correct memory parts

15-17-17-35 1.35v otherwise i set them manually but i cant make the pc boot

the problem is that once i set the xmp its very difficult to access to the bios..


any help / idea please ?

Hi em3d,


Have you tried the DIMMs in their paired kits? We cannot guarantee that 2 kits will work in a system, regardless of SKU. Also, the SKU is meant to only be used on an Intel platform so even then you might have issues when enabling XMP as the timings are not AMD optimized.

hi thanks for the reply... the two kits are now on the right place..

1st kit v5.39 - hynix (validated by Gygabyte for this MB)- into slots 1 and 3

2nd kit v4.32 - samsung - into slots 2 and 4


i do some homework and i discover the Ryzen RAM calculator..and others tools like thphn166


this MB lets you to apply different timings for each memory slot,

my question is : would it works?
