3200MHz RAM running at 2133MHz

Hello

Recurring question.

Your processor does not support the 3200MHz frequency for RAM.

Hi, thanks for your reply. Indeed, I just checked, they are limited to 2933MHz. Is it possible, despite being 3200MHz, that they run at 2933MHz and not at 2133MHz?

It depends on the JEDEC frequency table, you need to install CPU-Z and check the SPD tab.

Then, in any case, you have to set it manually in the BIOS.

Ok, I just installed it, I’m on the SPD tab but I don’t really know what to look at.. I’m a bit of a beginner, sorry. Can you tell me if it's possible to set them to 2933mhz with this?

In the table, you have 3 JEDEC columns and one XMP column.

Your RAM is currently in one of the JEDEC columns at 1066MHz, this frequency being the real frequency, it needs to be multiplied by two, making it 2133MHz.

Everything is normal.

Your RAM kit is not designed to operate at 2933MHz. That frequency should have been present in the table.

The only way is to manually increase the frequency in the motherboard BIOS. This is not without risk, as it can cause bluescreens and other crashes.

I advise you to leave it as it is, as it is the normal setting for your RAM kit, and you wouldn't notice any performance difference.

I assume that your 2 RAM sticks come from the same batch. The RAM in slot 2 is recognized by CPU-Z as a DDR4 3200MHz, so the other stick must also be a 3200MHz. Normally, by enabling XMP, your RAM should have operated at 3200MHz (1600MHz). Check if there is a second XMP profile you could try. Otherwise, you could attempt a BIOS update. In version F2, it says "Improve memory compatibility".

Maybe I wasn't very clear. It's about the motherboard and not the RAM sticks. Some motherboards have the option to enable 2 XMP profiles. We've heard testimonials from people who enabled an XMP profile that didn't work, and when trying the 2nd one, it set up normally.

I wasn't told something unknown. It's a well-known fact; you just need to look a little and you'll see that some motherboards, especially those from ASUS, have the option to enable 2 XMP profiles, XMP1 or XMP2. When I talk about an example I remember, it's because he was suggested to check if there was a second profile in his BIOS, and there was one. When he enabled the XMP2 profile, the RAM sticks worked at their nominal frequency.

Equivalent features to XMP can be found on overpriced boards, with different names such as DOCP for some ASUS motherboards, and EOCP for certain Gigabyte boards, which are performance-enhancing profiles when activated but resemble automatic overclocking.

XMP adheres to a standard, and it is a profile per module; when I have time to look it up, I will try to find that damn standard.

It is also possible that the confusion lies in the version of the standard:
XMP 1.0: DDR3
XMP 2.0: DDR4
XMP 3.0: guess!
