Hi,

 

It's likely that there is a hardware protection feature enabled in the BIOS.

Try putting the old memory back in > press F10 on boot to go to BIOS > select Advanced > System Options > turn off Pre-boot DMA protection

You can now put your new memory in

It could be in device or slot security. Sorry I'm not very familiar with that particular bios
