Guys, I've been running a B550 Phantom Gaming 4 board and Ryzen 5 3600 since late Winter 2021. 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 ------------- Jeff Heyen |

Disable XMP or reset to defaults in your UEFI to prevent issues with your first POST after installing the new kit. Either should work fine. Enjoy the upgrade  -------------

Xaltar, thanks for the reply. I'm probably overthinking this. Thanks for the confirmation of disabling XMP. ------------- Jeff Heyen |
