Re: Can not enable RAM XMP
I'm having issues with mine as well, XMP in BIOS will let me pick it but the machine crashes when stressed if I enable it.
Have left the BIOS to sort its own shiz with the RAM as I CBA..
Ryzen 5 1600AF, 3200Mhz RAM on a Steel Legend B450M BIOS 2.90
Re: Can not enable RAM XMP
Ryzen is a bit more picky about RAM timings - XMP is usually only verified for Intel CPUs at the moment unless you buy 'Ryzen optimised' RAM, which tends to be similar but with a few timings loosened.
I would go manual for Ryzen using the famous DRAM calculator:

(Conversely, for Intel I've found XMP pretty well optimised - every sub-setting I tried to investigate I found was already tightened up, which possibly explains why it's not working so well on Ryzen)
Re: Can not enable RAM XMP
I have an MSI MOBO. I set XMP and the voltage and its set to go. I can't remember if you need to specify the speed.
It boots as normal after you set the xmp? Its not having a fit and reverting to safe settings?
Re: Can not enable RAM XMP
Don't forget to ask ASRock support too - they may be able to test the RAM if they have it also (or they may ask you to send it to them so they can test it).
XMP for me works with Ryzen but my memory is 3600. I spend a lot on flarex too in the past just to make sure it worked with Ryzen 1 nicely.
Re: Can not enable RAM XMP
I would try adjusting the memory settings manually & seeing what are the fastest stable settings you can achieve. Also, if there is a bios update available, it's possible that it may address ram compatibility.
As an interesting aside (and a bit OT I know), Intel actually considers XMP a form of overclocking. If you ever need to RMA an Intel CPU under warranty, Intel support will ask you whether you were using XMP, and if you answer 'yes', they will tell you that the warranty is void! (I saw a Gamers Nexus video about this).

:o
You're absolutely right.

Re: Can not enable RAM XMP
Well TBF,it might apply to AMD too. Both Intel and AMD have officially supported memory speeds on their CPUs. IIRC it's 2666MHZ for Intel,2666MHZ for Zen,2993MHZ for Zen+ and 3200MHZ for Zen2. Anymore is technically running the IMC at an overclock,so AMD is actually more generous than Intel here!

What CPU does the OP have??
Re: Can not enable RAM XMP
Hi, I`ve searched the datasheets at HyperX https://www.kingston.com/dataSheets/...5PB3AK2_16.pdf and it looks like your memory comes with 2 xmp profiles and default settings of 2400Mhz. Now, having Asrock motherboard myself (ab350 pro4) I can tell you it worked on mine, but I did modify the setting to manual (Ryzen7 3700x, corsair vengeance 3200 MHz).
Re: Can not enable RAM XMP
The XMP profile on my RAM isn't stable either. With some tweaking using the RAM calculator it's actually stable at a faster speed than XMP.
Re: Can not enable RAM XMP
I would always use manual rather than rely on XMP. Have done ever since I had issues with it on s1156. I also find you can often drop the voltage from what XMP thinks you need without having to worsen any of the timings. I'd much rather know what voltage is happening than trust something else to get it right for me (when experience tells me sometimes it is rather cavalier!)
Re: Can not enable RAM XMP
Look into manually overclocking your RAM, it gives you a lot more control over these things and you can fine tune it so it actually works for your CPU/mobo.
Re: Can not enable RAM XMP
I'd recommend looking into manually OCing your RAM, you get a lot more control over speeds and timings which you can fine tune to work with your specific system.
Re: Can not enable RAM XMP
Changed my BIOS, all good now..

yes, we heard you the first time. We just chose not to respond.
