DDR5 Query with MSI Pro 760m-P

West · 2025-02-11T15:47:26+0000

Good afternoon,
I've recently purchased a PC with the Pro 760 M-P.
I needed to upgrade the RAM to 32gb - Specifically I purchased CMH32GX5M2B6400C36
Having check on the MSI website this isn't on the list for this motherboard as being "Compatible"
The BIOS is recognising the RAM and all the correct details, will the RAM work as it should do? only issue I seem to find with it is it won't use the XMP Profile on the BIOS.
There are similar kits just not at 6400mhz even though the board is rated to use 6400mhz DDR5.
Is there likely to be any issues or long term consequences using this kit?
Thanks

What CPU are you using?

All 12th gen and 13th-14th non-K CPUs may struggle to hit those speeds, depending on the CPU's memory controller.

12700KF Worth swapping for a lower kit or just take the hit? I'm happy if it wont reach the speeds as long as I won't get any degradation in overall performance or any issues?

Will it run to what it can or would I need a compatible set to run at the speed? I'm guessing I'll need a new set as it won't run the XMP Profile as its not currently compatible?

Usually what you can do, to get faster than the boot-up speed, is to enable XMP and then set a lower frequency e.g. 6000 and see how that goes.

What is the current speed with XMP disabled?

If the CPU is running at 4800, for example, that would be a hit to performance, but it depends on what you're doing with the PC.

You should be able to achieve at least 5600 without any problem.

I'll need to get back to you on that one. The PC has gone back to where I purchased it from as its not right! So under the warranty they're just checking some bits for me.

It's a Flight Sim PC for occasional use with other games but its a gaming PC essentially.

12700KF, originally 16gb of DDR5 5200, Zotac 4070 and 2 Nvme.

So for example I know I'm not going to get the 6400 potentially, it can be clocked to run at 6000 without any stability issues or potential for abnormal failure? According to the list there are compatible 6400mhz kits but most of the Corsair kits look like they run at 4800 (the SPD Speed??)

I'm genuinely not massively fussed about changing them unless needed but want to maximise what I can get out of them without blowing my board up or causing errors

Umm. How strict do you want me to answer here?

If I answer you literally, using XMP is overclocking so there's no guarantee of stability if you do this.

Your CPU officially supports just 4800.

In reality, pretty much everybody will use XMP to run at least 5600, likely 6000, which shouldn't cause any long-term issues with the CPU, motherboard or memory.

I'd be surprised if your CPU can't do at least 6000.

In honesty if I can do it with the kit I've got i don't mind. That's my main question I suppose or do I need a kit that's strictly compatible with my Mobo?

My guess is that your kit is fine with the motherboard, but the CPU's memory controller can't do the rated speed of 6400. I'd try with XMP enabled and setting the frequency manually to 5600. If that works, try 6000.

If it works, you would need to do some stability testing, unless there's literally nothing on the PC you care about (due to BSODs and silent data corruption if the memory is not stable).
