Thanks for the reply. 

It's an HP (Compaq) CQ5826, it only has two open x1 slots on the
motherboard. There are no memory settings in the BIOS.

A Radeon 5450 is what I bought for the other desktop (also an
HP/Compaq), which has x1, x16 and legacy PCI slots, despite
being two years /older/ than the CQ5826. That has an on-board NVIDIA
GPU which has caused issues with Linux, it would crash if I used
certain desktop environments. With the new Radeon card in that, it now
runs like a brand new machine.
