I had attempted to upgrade the Memory on a Dell Vostro 230 Desktop PC, but ran into problems. The Client’s Computer had 2 Gb of Memory (2 x 1Gb), and I attempted to upgrade the computer to 4 Gb (2 x 2Gb). Each time I upgraded (I attempted this 3 times, with 3 different types of Memory–different Memory products), the Computer would NOT boot and would give beep codes. Yes, at times the you may experience a problem with incompatibility. After the 3rd attempt, I was convinced the Memory could NOT be the problem. Instead, the Dell Vostro 230 had to be the problem. The Dell Vostro 230 took DDR3 Memory, but all new Memory modules were running at faster speeds than the original Memory.
After some research, I decided to upgrade the BIOS via “dell.com” download…and that fixed my Memory upgrade issue.
Moral to this story…probably a good idea to upgrade the BIOS of an older Computer before upgrading it’s Memory. Normally, I don’t suggest you upgrade the BIOS as this could render the Computer totally useless if the BIOS update fails.
Client is now very happy…as moving from 2 Gb to 4 Gb was a significant improvement.
Hope that helps.
