Trying to add NVMe SSD but confused.

I got a new NVME SSD for my Dell 7050 micro Optiplex but when I go to install it I get a 1,3,2 beep code the moment I plug in the power. The PC boots fine with just the old SATA SSD installed but if I try to plug in and boot with both or just the NVME installed I just get the beep error. The 1,3,2 seems to indicate a RAM issue but it boots fine with the old SSD so that's weird. Is there something I'm missing? Its a Gen 3x4 m.2 2280 NVMe 1.3 SSD.
