Question RAM still stuck at 2133MHz desipte setting XMP profile

Hello, after noticing on HWin that my Current System Memory Clock is an abysmal 1064.3MHz (I believe you double this to get roughly 2133MHz which is the default frequency of the RAM I'm using) I have tried to apply an XMP 2 profile. I've checked to make sure that the settings changed and that the timings are correct to achieve the advertised 3000MHz but so far there is no change. Any help would be greatly appreciated. Here are my specs:

RAM: Corsair Vengeance CMK16GX4M2D3000C16
CPU: Ryzen 5 2600
GPU: Radeon RX Vega 56
Mobo: ASRock B450m Pro4-f
OS: Winows 10
PSU: Corsair VS650
BIOS is updated to latest version 1.5

EDIT: After playing around with it for a while I noticed that even though my BIOS timings 16 20 20 38 HWin repots that they are still at 15 15 15 36. Is this a possible bug with the BIOS?

Make sure the memory is in the correct slots or AXMP won't work, it's usually A2/B2 (slots 2/4).


Side note, you may not want to use that GPU with that PSU or at the very least undervolt the GPU.

enable DOCP in BIOS so that the XMP get's translated for Zen because Zen doesn't work with XMP by default.

Just be aware that you will most likely only get it to run at 2933MHz not 3000MHz exactly.
Hello, I've looked through all the settings in my ASRock BIOS but I can't seem to find anything to do with DOCD. Wouldn't it just be presumed that if you're using XMP on an AMD based motherboard you will need DOCD?

Yeah I've checked that already with my motherboard manual. They are in A2 and B2. Also about undervolting, do you recommend that because of overheating issues? I've heard a bit about it but I'm not sure why its necessary.

if the XMP 2 profile isn't taking, and there doesn't seem to be any DOCP option, then check to see if there's an update to your BIOS.
After updating the BIOS if update is available, try again.

If already on the latest BIOS, you can try to manually assign the overclocks to the RAM by putting in the speed and timings listed on the sticker on your RAM sticks.

If that doesn't work, then a CMOS reset is in order to try and fix any issues.

And if CMOS reset doesn't work, then I honestly don't think I'll be able to help any further.
