Question 3200mhz RAM running at 2400mhz despite XMP being enabled?

[NokiDokki]

RAM: TeamGroup T-Force Vulcan Z 16GB(2x8) 3000mhz + 16GB(2x8) 3200mhz
Mobo: MSI B450 Tomahawk Max II
CPU: Ryzen 5 3600

My system fails to boot every time I bump the DRAM frequency past 2400mhz (even with XMP enabled). I've changed the voltage from 1.2 > 1.35 with no issues. however, it still did not allow me to change the frequency. Is this caused by differentiating ram speeds? Thanks!

XMP Profile: DDR4 3000MHz 16-18-18-38

No. It's caused by a mismatch of silicon. You can try adjusting the timings of the ram, adding voltage to the memory controller etc.

There's only 3 possible outcomes when it comes to mixing ram kits.
It works.
It works with adjustment.
It doesn't work.

Make sure BIOS is up-to-date and RAM installed in slots a2-b2.

he does have four modules..and two totaly different sets

for OP , XMP is totaly out of your options, manual overlocking only...but there is no telling how far you can overclock with totaly different mem ICs

hint: ram overclocking isnt just raising frequency, you will need to tune up timings aswell, they can be calculated once you get baseline for both stick sets

voltages on ram arent important, at start (around CL20), they do become important once you want to reduce timings (to get better overclock)

you may however want to tweak memory controller voltages a bit with four sticks

Now I see it. 🦇
