I just got a new 1GB memory stick to upgrade a desktop PC from 1GB to 2. The problem is, the new memory has not been recognised. The PC has 2 slots, one of which was initially empty, and the memory details are: 1GB DDR2 PC2-5300 667MHz (both old and new match these specs).
So far I have:
- Tried the old and new memory one at a time - both work fine, giving 1GB each.
-- (I've done this in both slots, so I know those are good too)
-- (I always ensure the memory clicks fully into place, as I know this can be a source of problems)
- Removed and replaced the motherboard battery to force it into a full refresh, then rebooted with both memory sticks installed.
-- (Advice elsewhere said this might force it to see the new memory, but it did not work)
So far I haven't:
- Upgraded the BIOS
-- Following the Phoenix website link suggests I have to pay for upgrades, so I'll try that option if people think it will help.
The boot-up text shows "DDR2 at Row(s): 1" when both are installed, which I interpret as meaning the BIOS itself can only see one of them. Is there anything in the BIOS settings which might help?
System details are below. Note that this is a relative's PC and I see them infrequently, so won't get to try out suggestions straight away, but will do my best to provide any extra info if needed.
