I have HP Workstation xw4600 (datasheet) with two ECC RAM modules in it. I want buy more RAM modules, specifically two regular non-ECC DDR2 800 MHz. Will these non-ECC RAMs work with this ECC motherboard? If yes, will they work together with the two ECC RAMs or I can use only one type? Thanks.
Depends on if your able to disable the ECC feature within the firmware. It's very unlikely if your unable to do that the system will boot and if it does it might be unstable. – Ramhound – 2017-08-06T21:09:14.557
