Hi all,

I'm currently using 16GB HyperX Fury 3733mt/s DDR4 RAM, and am considering upgrading to 32GB Corsair Vengeance Pro SL 4000mt/s RAM, which also has lower CL timing.

My question is, how do I find out for certain that my motherboard is capable of utilising the full 4000? Currently my RAM is set to the 3733mt/s using the XMP profile in the BIOS settings - and I can see this is working as it should using CPU-Z - but I'm not sure how to find out if it can do 4000?

It's an HP OMEN Intel Z690 motherboard.

Cheers!
 
Ram has to match CPU and motherboard.
Most MB's will take a faster ram than what the cpu can handle.
So if you buy 4000 ram and cpu can only handle 3200 no benefit and wasted money.
Complete model number and serial number of the HP please.
 


The maximum RAM speed capability of the N5 Z690 Intel ATX motherboard can be found in the “Specifications” section under “Memory.”

As per post #2
The cpu comes into the equation. The MB can take 3 Types of CPU i5/i7/i9.
Looking at the MB & CPU specs for all 3 cpu's the best you can hope for is Up to DDR4 3200 MT/s
 
Thanks for the responses.

The PC is a HP Omen 40L GT21-0000i. I'm currently using a 12700K - the CPU the PC came with - but considering upgrading to a 14900k.

The current HyperX RAM that the PC came with is running at 3733mt/s using XMP on the out of the box set up with the 12700K.
 
Also, would I be right in saying that - per the calculator in the image - option 2 should actually be the best in terms of speed/responsiveness, despite running at lower mt/s? 1 is my current RAM and 2 and 3 are the specs of two others I'm considering for the upgrade if the 4000mt/s isn't doable.

The difference in those tests are 3 nanosecs.
One billion nanoseconds make 1 second, so I doubt you'll even be able to notice a difference.

It really comes down to compatibility and cost.
