My computer crashes when I enable the XMP profile.

Hello everyone,

I'm posting this message to ask for your help!

I recently bought a gaming desktop, so far so good.

But recently, when I took a little tour in the BIOS, I noticed that I hadn't enabled the XMP profile, so I activated it and then got a blue screen followed by automatic repair.

As soon as I disabled XMP, there were no more crashes...

I tested it several times, always the same problem...

I then tried to update my BIOS, but there's a new problem; on my motherboard's site, there are 3 versions of my motherboard (rev. 1.3, rev. 1.4, rev. 1.0/1.1/1.2) and it's impossible to know which version I have, it's not indicated anywhere, so I can't update my BIOS.

Here is my config:

- Ryzen 7 5700X

- RX 6800 XT

- Corsair Vengeance RGB RS 16GB (2 x 8GB) DDR4 3600MHz C18 Memory

- GAMING X V2 (BIOS Version/Date American Megatrends International, LLC. F16b, 08/02/2023)

Thank you in advance!!!!

Hello

It's normal, your RAM kit has an XMP profile at 3600MHz while your processor only supports up to 3200MHz. Don't worry, you won't notice any significant performance difference in use.

Just make sure it runs correctly at 3200MHz in normal mode.

For the motherboard revision, it's written directly on the motherboard, you'll need to open the case.

The other solutions through software are not 100% reliable.

Thank you for your response!

Currently, it runs at 2133 MHz :/

Install cpuz and post screenshots of the memory and spd tabs.

As you can see in the timing table, your RAM jumps from 1066 MHz to 1800 (you multiply by two to get the effective frequency), the setting is good, it works, but this RAM kit is not suitable in frequency for your PC.

So I'm at 1800 MHz?

Would this RAM be suitable for my computer? (https://www.ldlc.com/fiche/PB00271616.html)

I couldn't find any information on the motherboard regarding its revision, but I imagine that updating the BIOS isn't of utmost importance.

Thank you!

You have the actual frequency on the memory tab, 1064 MHz, which needs to be multiplied by 2 to obtain the usage frequency, also known as the commercial frequency, which shows up in Windows, so you have 2133 MHz (2124 exactly).

This is not a problem; the performance difference is very low, if not impossible to measure.

That being said, the kit you found would work at 3200 MHz by enabling XMP, and you can find it cheaper here: https://www.materiel.net/produit/201905130003.html#a_aid=5ba117fccc029&data1=m%E9moire

CPU-Z can read the motherboard revision in the motherboard tab, but this is not as reliable as the inscription on the board itself. The BIOS may already be up to date, and you can see this in the motherboard tab; an update is only necessary when you want to install another unsupported processor with the installed version; otherwise, as long as it works, it's best to avoid it.

The built-in memory controller in the Ryzen 5000 automatically manages frequencies up to 3200MHz, while B550-based motherboards allow exceeding this limit. Like with Intel, it was only from the 10th generation that the integrated memory controller could handle up to 2933MHz, instead of the maximum 2666MHz. However, they allow for overclocking, and one can go well beyond this limit through OC. Thus, the GAMING X V2 is supposed to handle modules up to a maximum frequency of 4733MHz through O.C, so it should have managed a frequency of 3600MHz. If it can't, then there is an anomaly.
