Biostar B250 pro MOBO

[BTC22]

This is the motherboard I picked up for a second rig (AMD). Im using a 7th Gen Celeron Processor for this that supports 2133 DDR4 Ram, which the motherboard supports. The RAM I bought doesn't fit. It's 288 pin, but the little cutout doesn't match up right. I want to order another stick, but I want to make sure I get it right.

Correct sir, that's the type of ram you should buy. About the problem first ram you've bought, have you komplin to the shop / seller ? , as far as I know if it's a 288 pin ram, it can be installed without problems.
