[SOLVED] Can't change clocks of my memory

Hello!
Built my first PC yesterday. Using HyperX Predator 2x8GB 2933MHz RGB RAM. The thing is: When I open task manager it says my memory clock is 2400MHz, but I want it to be at least a bit higher (I mean I paid for it), so I went into the BIOS where there's a setting to change memory clocks. So far it had been on auto, but I changed it to 2666 aaaaand nothing changed. The clock was still 2400MHz.

Decided to try use XMP (by default on auto) I set it to one of the 2 profiles. What changed is the clock on the clocks setting (still the actual clock detected by my PC was 2400MHz) and it changed the voltage of my RAM. So I guess it overclocked my memory in order to get my memory to work at a clock, which could be achieved at the same voltage? (also it said it will change the timings, but I don't understand that)

Is it possible that when on idle it uses default settings, but when under load it uses the higher clocks, I've set? And does XMP activate automatically, because I don't want it to increase my memory voltage when the clock it wants to achieve doesn't require that? Or maybe it was marketed as 2933MHz, because it can reach it with XMP? (even though I never noticed it going to 2933MHz).

I really appreciate your help!

Did you follow ALL of the instructions between the BIOS version you already have installed and the version you are installing, including potentially having to install other previous versions FIRST before you can install the latest version AND also installing the AMD all in 1 with VGA driver ver:18.50.16.01_WHQL ?

I would go back to the support page, CAREFULLY read ALL of the notes listed at the bottom of each update section in yellow, follow any specific notes and procedures and if necessary install an prior versions that are required before installing the latest version. Some boards and chipsets will allow you to jump directly to the latest version from even a very old version, others will not.
Yeah, wished memory worked like that for you but sadly not. Whatever memory is set to in the bios is it.

XMP sets timings, voltages and frequency according to the memory's specifications. It's perfectly normal to see 1.35v as this is what DDR4 is spec'd to run at over 2666MHz.

My suspicion could be the motherboard's chipset preventing you running over 2400. Can you list your system specs please?

Thanks you for the reply! I'm using a Ryzen 5 2600X, my RAM is HyperX Predator 2x8GB 2933MHz and my mobo is ASRock B450M Steel Legend. I also assumed it may be chipset or bios. My chipset drivers are the latest, but my bios is a couple versions back and in one of the new ones is listed a fix for my problem. If that is the problem, then I just need to wait a couple days for ASRock to bring their utility download link back online.
 
Yeah probably. Make sure to load bios optimised defaults after update to refresh cmos.

1st and 3rd dimm slot can restrict memory overclocking but you're good.

Where are you reading ram speed after setting XMP in the bios? Can ya post a screenshot of cpuz memory & spd tab please.

I'm reading memory speed in task manage, but now I installed CPU-Z and here's the memory tab together with the clocks tab. Interestingly there isn't any info about my memory in the clocks tab. Also the clock in the memory tab doesn't seem to be proper as it is a lot lower than what task manager says. (also in the bios I think it also says that it is running 2400MHz) View: https://imgur.com/a/Jxccxjm
 
Thanks. Wanted to check the timings table and see what your memory supports and they do have a profile for XMP-2936.

Try manually adjusting your ram. 2933, include timings in advanced timing control and don't forget the voltage to 1.35v

Dram calculator can also help. Take a picture of the values it detects and enter those in the bios.

Why doesn't it work just increasing the clock from the bios or just enabling an XMP profile? (tried and doesn't work) Also how can I know my RAM type? There's Hynix MFR etc.

Changing speed itself won't work because timings and voltage also need to be changed which XMP does automatically. Sometimes Ryzen motherboards can be stubborn and adjusting ram manually can help.

It's daunting i know entering many fields, probably get away with entering the main timings but it's something to try before bios update which may not be assured to fix.

On bios updating though, if you can help it, update in the bios itself using it's update tool rather than from Windows. It's a lot safer this way.

I tried doing it the manual way, but it said it couldn't find an image file. Also how can I know what type is my memory? MFR, AFR, CJR, DJR?
 
Fat32 formatted usb drive with bios rom file extracted to it no folders.

Info here how to find out IC chip information on your ram.

It isn't really a rom file. It's just... a file. I'll check out the tread you sent me

I should have the driver, cause I have a version after the warning for the driver. I dont know if I need to upgrade step by step. Will try. I straight up tried to go 2 versions up. Thanks for the reply btw!
