Question Ram won't work above 2400MHz

[Domnu_Gascu]

Hello! So recently I boutght a new set of ram to put in my pc but I have a slight problem. The ram I bought is normally working at a speed of 3200MHz and is currently working at 2400Mhz but that's not really the problem,my problem is that before I bought this set of ram sticks,I had another set of ram that worked at the speed of 2666MHz and I expected for these to work at a minimum of 2666Mhz aswell and I can't change the speed from my bios. Can someone tell me why they work at that speed?

What are you full system specs with motherboard model.

We don't know, what cpu or motherboard or ram, you're using.
If I had to guess, probably ram modules doesn't have necessary SPD table entries for 2666mhz mode and using ram at higher speed than 2400mhz, requires use of XMP.

It would be great, if you could provide us with screenshots from CPU-Z - motherboard, cpu, memory, spd sections.

That's the reality of mixing RAM sets with different specifications. It often ends up that way that you can't run it anything higher then base speed. Sometimes it can be fixed by setting proper values manually.

CPU:Intel core i7-8700
Ram:T force vulcan-Z 2x8GB 3200MHz
Gpu:1660 super
Mobo:Asus Gl12CP(it's really hard to find online)

ASUS ROG Strix GL12CP gaming desktop pc?
It has H310 chipset board.
Ram can run at 2666mhz max with i7-8700.
Ram needs to have spd table entry for 2666mhz mode.

Yeah. As suspected - there are no SPD table entries for 2666mhz mode.
If BIOS of your board doesn't allow manually changing DRAM parameters, then 2400mhz is max you can get (with these particular ram modules).
