3200Mhz ram stuck at 2133Mhz Prime b450m-a II motherboard

[LoganTroy]

Built my dad a new pc, ram refuses to be at higher frequency.

 

DOCP is enabled in bios with the profile of DDR4 3200Mhz but after reboot it still shows as 2133Mhz. I’ve verified motherboard supports ddr4 and 3200 mhz, ram is slotted in channels 1 and 3 (b1 & a1). Updated the motherboard bios to most up to date version and still have the issue.

 

Any suggestions?

those aren’t channels, those are slots. If your motherboard has 4 slots they should be in slots 2 and 4. Try again with the ram in the correct slot and see whether it works?

Switch it to slots 2 and 4 (A2 and B2) as those are the optimized slots on that particular board. 

 

Anyway, where are you reading the frequency? From what I remember about ASUS boards, their BIOS screen will always show the JEDEC values for the memory kit in the place you'd expect to see the memory frequency, so it's possible that it is running at 3200MT/s and your readings aren't correct. 

 

There are some other things that you can do, but to save myself the typing try those first.

Ram part number and rev / CPU would be helpful

On this motherboard, Ram always  shows at jdec speeds in bios.

 

what does it say in windows?

I’m going to be installing holoiso to make it a steam machine so don’t have windows. I’m in the middle of downloading the iso image now so I’ll double check once I’ve got it installed.

Gotcha I was thinking that might have been the case. Don’t have os installed going to do do a steam machine build with iso will double check once I have it installed.

Reading from bios, good to know will try those

Looks like it’s still at 2133Mhz in slots 2/4 will have to pull up the terminal to look at speeds once I have steam os installed

Does the docp tab in the bios say 3200?

 

if so it’s at 3200mhz, but sticks are labeled by their stock speeds in the bios

Sweet, sounds like my dad is g2g for some games. Thanks for the help.
