Guys,

I've been running a B550 Phantom Gaming 4 board and Ryzen 5 3600 since late Winter 2021 (earlier this year). System has performed flawlessly. Current memory set up is a Crucial Ballistix DDR4-3200 16GB kit (2x8GB) in slots A2 and B2. I set up XMP profile to run at 3200, and system has been totally stable.

I decided to up the memory with an additional 16GB kit (same as above), but then read of memory slow downs when you populate all four memory slots. So, I picked up a GSkill Ripjaws V DDR4-3200 32GB kit (2x16GB). I'm not worried about getting rid of the two Crucial kits, as I'll post them for a good price on Craigslist.

My main question is this - prior to swapping out the Crucial sticks for the GSkill sticks, should I disable the XMP profile? Any other suggestions I should follow?

TIA,

Jeff

You shouldn't have to pre-disable XMP, although it wouldn't hurt anything. I'd expect the board to re-train on the new memory at non XMP speed, and then you can go into the BIOS and (re-) enable XMP for the new RAM.

I have your same MB. I tried installing 4-8Gb Corair Vengeance 3600 ram. No go with its XMP profile. Best I can do is 3200. I also have an Asrock B550M Pro 4 MB with 2-16Gb G.Skill 3200 ram and it runs fine at its XMP profile, so, no guarentee, but the G.Skill ram should run ok on your MB at its XMP profile.

Mad Scientist,

Thanks for the info. This is more of a "whim" thing than anything else, as I don't do anything that requires 32GB. That said, I got the GSkill's at the right price, and I'll have no trouble selling my two 16GB (2-8GB) Crucial kits on Craigslist.
