Hey everyone! So I'm currently working with a Ryzen 5 1600 AF build and have a B450M PRO-VDH Max motherboard. My setup includes a GT 1030, and I've been running 16GB (2x8GB) of Corsair Vengeance LPX DDR4 3200 RAM without issues. Recently, I upgraded to an R7 5700X and added 2 more identical 8GB RAM sticks to have a total of 32GB. However, my system won't boot with all four sticks installed. It seems to power on but has CPU and memory debug lights showing up. When I try running just 3 sticks, the system boots but shows only 16GB as usable and is pretty unstable, resulting in bluescreens. I've tried adjusting settings like lowering the frequency to 2133 and disabling XMP, but nothing seems to work. Do you think there's a chance my setup is just incompatible, or should I reach out to the seller for a possible return? Any advice would be greatly appreciated!

It sounds like your motherboard is having a tough time handling all four sticks. Sometimes mixing matching kits can cause instability. Also, make sure the RAM is seated properly; it can be a simple fix! If it still doesn’t work after all that, I’d suggest reaching out to the seller for a return, just in case something is off with one of the sticks.
Hmm, did the RAM come as a quad kit, or were those sticks from different kits? If they’re mismatched RAM (even if they’re the same model), that can sometimes cause issues, especially when all four are installed. Maybe check if the motherboard is on the latest BIOS version too. That can sometimes help with RAM compatibility.
Yeah, I had a similar issue once. Updating the BIOS fixed my RAM problems. Might be worth a shot before returning anything!

Definitely double-check those seating connections. I’ve had RAM sticks that looked fine but needed a firmer push to get them working together.
