DDR5 RAM

Hi Guys,

New to this PC stuff, I'm looking at upgrading my ram currently from 16gb DDR5 to 24GB by adding an 8gb stick, I was wondering what RAM will be compatible in my system. I've attached a screenshot of whats already in it, any suggestions would be grateful.

You wouldn't normally upgrade 2x8GB sticks by adding a third 8GB module, you normally want to stick to matching pairs of sticks.

If you need more RAM you'd be best served removing your 2 existing sticks and adding 2x16GB sticks.

What are you trying to achieve with the RAM upgrade? What needs more RAM?

I can't find any information for that part number, is your PC an HP?

A bit weird that it has EXPO/XMP profiles for running at 5200, that's a slow speed and I wouldn't normally expect it to need that.

Since the memory chips are Micron, a Crucial stick would be my best guess for compatibility, but mixing sticks with different XMP/EXPO profiles (or that don't need it) is going to have unpredictable results.

Hard to recommend anything other than upgrading to 2x16

Thats correct its a HP PC.

What two RAM sticks do you recommend I buy?

Can you get us the part number of the PC?

Or, failing that, the motherboard model?

You can also put that information into the Crucial or Kingston configurators and they should give you a recommendation.

The pc product number is 8C6T9EA#ABU

Hmm. The configurators don't expect it to be in this format.

If I google it, I get HP 40L GT21-1021. Does this look correct?

If so, then I think this would be the output from the Kingston configurator:

Memory for a HP/HPE - OMEN Desktop 40L GT21-1xxx (DDR5) - Kingston Technology

Kingston has compatible memory for HP/HPE - OMEN Desktop 40L GT21-1xxx (DDR5)

Very limited part numbers suggested there, those are just basic JEDEC modules without XMP/EXPO.

Is it possible to manually enable EXPO/XMP on your PC? If it is, you could pick from a lot more options, like a Kingston Fury kit instead of those basic green things.

OP, use this tool to check which RAM is compatible with your system https://uk.crucial.com/store/advisor

As the others have quite rightly pointed out, you should rather get a matched pair of memory modules rather than adding a single 8gig DIMM to your current config.
