[SOLVED] Ram compatibility with cpu & mobo

[Gumbe4ux]

I recently bought a new mobo and processor. The mobo says that it will take DDR5 @6400MHZ. So that's what I ordered. The cpu I bought states that it supports DDR5 @ 5200MHZ . Im concerned the new ram I ordered won't work. Do I need to cancel the order and buy different ram? I would be extremely grateful for some insight.

CPU and MoBo in question are?

But overall, MoBo states RAM OC profiles, and RAM does work. Perhaps not at advertised OC speeds, but for sure at JEDEC standard speeds (4400/4800/5200 Mhz).

RAM: https://www.newegg.com/g-skill-32gb/p/N82E16820374451?item=N82E16820374451 just incase!

Instead of just the names I listed the products with a link hoping this will help
Thank you!

According to MoBo specs,
link: https://www.asrock.com/mb/AMD/B650 LiveMixer/Specification.asp#Specification

Your MoBo supports up to 6400 Mhz.

And from RAM specs,
link: https://www.gskill.com/specification/165/377/1668503353/F5-6400J3239G16GX2-RS5K-Specification

You can read the following:

For memory kits with XMP/EXPO, enable XMP/EXPO/DOCP/A-XMP profile in BIOS to reach the rated potential XMP/EXPO overclock speed of the memory kit, subject to the use of compatible hardware. Please refer to the "How to Enable XMP/EXPO" guide.

Btw, CPU manufacturers doesn't list OC RAM speeds under their CPU specs, since none of the CPU makers acknowledge that you can OC the hardware. Thus, they list the JEDEC standard RAM speeds under CPU specs.

For example, i'm running i5-6600K,
specs: https://ark.intel.com/content/www/u...56600k-processor-6m-cache-up-to-3-90-ghz.html

And while it says there that supported RAM speed is 2133 Mhz (DDR4), i'm running 3000 Mhz RAM instead, with 0 issues.

Overall, i don't see an issue with your RAM.

However,
If you want a guarantee, pick a RAM from MoBo memory QVL list,
link: https://www.asrock.com/mb/AMD/B650 LiveMixer/Specification.asp#Memory

Since those RAM sticks have been tested by AsRock, in house, and are guaranteed to work at those speeds, as seen on memory QVL.
This is actually how i picked my RAM as well. Since i have MSI MoBo, i looked memory QVL list and bought the RAM, which runs at 3000 Mhz, while all 4 RAM slots are populated. And sure enough, i have 4x RAM sticks and they all run at 3000 Mhz problem free.

Aeacus you are the man. Extremely useful and helpful info. Im very grateful for the help. I think I'm going to let it ride and just test it out when it gets in. I'm upgrading from a LGA 1150 sandy bridge! Its been way over due. I cant even upgrade to windows 11. I've always been an Intel guy and decided to switch sides and give AMD a go. My brain turns to mush shopping for components. Like anyone, I want the best value and performance for the money. Thank you once again!
