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!

seriously doubt you'll notice any performance improvement unless the timings are significantly lower.

are you just having an issue with lack of available RAM?
then a 32GB(2x 16GB) kit would possibly be worth it.
if you could find a cheaper, even lower latency 3600 kit it would be an even better option.

Just juicing the PC up for some 4K gaming. Will also be going from my 12700K to a 14900K and from my 3070 Ti to a 4080 Super.

The current RAM is 3733mt/s and CL22. The Corsair RAM mentioned in the original post 4000mt/s and CL18, but I'm struggling to confirm whether my board actually supports the 4000 or not.

It's not only up to MB, it's also about CPU where IMC (Internal Memory Controller) is located and also has te be overclocked above it's base frequency. Yes OC, because base frequency for DDR4 is 2133MHz.
 
HP pre builts are not planned to be upgradeable.
Do you know for certain that the motherboard has a bios that will support a 14900K?
If the ram you buy does not get to 4000/18, it should run at lowered settings.
The benefit of 32gb vs. 16gb is probably more important.

Oh, really? Part of the selling point used in the description for the OMEN PC's is that they're easily upgradeable. I have always assumed that being a Z690 board it would definitely be compatible with a 14900K.

How do I find out for certain? I do know there is a BIOS update available for my system.
