Hey there, I’m used to working with computer builds but mostly stick to Asus boards. I’ve had trouble with generic proprietary chips like Dell, HP, etc., and even experienced problems with Gigabyte MBs in the past (especially around Ivy Bridge and Haswell). This time I decided to try MSI and bought six B550-A Pro AM4 units. Now I’m seeing some RAM quirks when I try to use more than two modules at once. I’ve upgraded the BIOS to the latest version available on MSI’s site (version AB0 or similar).
The main issues I’m facing are:
- When using more than two modules simultaneously, the system freezes and the CPU indicator stays lit.
- Booting from a single module works fine, but sometimes the CPU light fails at startup.
- Rebooting helps in most cases, though it can cause occasional CPU light failures.
- Using one or two modules doesn’t trigger these problems, even with 2–4 modules.
I’ve tested different CPUs—Zen2 and Zen3—and even mixed in Corsair Vengeance modules, but the symptoms persist. I’m wondering if the timing settings might be too strict for the memory controller, or if disabling XMP isn’t helping. It seems like these boards can be tricky with RAM setups.
I’m not sure if this is just my luck, but I’ve heard Dell boards can be finicky in this area. Thanks a lot for your help!
Best, -a-
During additional testing, I also used four 16GB DDR4 3200MT modules from Kingston Fury HyperX, which worked fine with two units and didn’t cause reboots when using four. This revealed that disabling XMP/DOCP resolved the issue. It seems this model only supports XMP/DOCP with two modules, not with four. Disappointing. I probably shouldn’t have bought six of these; it’s possible a BIOS update could help or it might be a hardware limitation. I’ll likely stick to Asus boards for future purchases.
Based on what I've read, motherboards tend to be less important compared to other PC components, so brand isn't a big deal. But RAM is different—using a Samsung B-die setup works fine and is reliable. For more than two RAM sticks, Ryzen generally dislikes it, though using a B-die might help a bit. Just stick with what you need.
I’m still trying to figure out what B-die means and need some research. Here’s what I understand: - I’ve had a rough time with the lottery lately, especially with all the 6 units of the MSI B550-A I bought showing identical issues across more than two RAM modules. - On other PCs with Ryzen CPUs and four RAM slots (including two with 4x32GB DDR4 3600MT), everything works fine on Asus X570 boards. I’m not sure if X570 is better than B550 or if Asus is superior to MSI, but since this was my first time buying MSI parts, I’m hesitant to repeat the mistake.
