Question XMP RAM on Asrock B650M PG Lightning Wi-Fi motherboard ?

[Pimpom]

I'm going to build a new system for someone else based on an Asrock B650M PG Lightning Wi-Fi. I haven't decided on the CPU but it will be from either the 7000 or 9000 series.

For the RAM, I'd like to use an RGB 6000MT/s 16GBx2 kit. Budget is a bit tight so I'll have to settle for CL36. The cheapest one I can find is G.Skill Ripjaws M5, model F5-6000J3636F16GX2-RM5RK. It's on the QVL but it's XMP only, no EXPO, and so are those priced at a few dollars more. They're not on the QVL for 8000 CPUs.

I vaguely recall reading somewhere that even AMD motherboards stated to be XMP-compliant may have a problem with XMP memory. Is there any truth to this?

There is. After all XMP = Intel Extreme Memory Profile.

XMP profiles may or may not work on AMD chipset MoBo.

EXPO is the highest chance of working, especially when RAM is from memory QVL.
XMP has less chance of working, but i'd still put it high, especially when MoBo supports it and RAM is from memory QVL.
Non-memory QVL RAM EXPO/XMP profiles working has 50:50 chance.

For the RAM, I'd like to use an RGB 6000MT/s 16GBx2 kit. Budget is a bit tight so I'll have to settle for CL36.

Have you looked at 4800 MT/s RAM? Since that's JEDEC and would work regardless. No need to mess around with XMP/EXPO. Also, RAM could be cheaper with lower CL.

Nice part is, that RAM can be easily upgraded at later date. (Just like e.g upgrading GPU or SSD.)

See if something here fits.

Asrock bios has default settings for XMP and EXPO , it can read and apply OC settings for each standard equally. Just make sure you have latest version. Both can be manually adjusted too.
