I'm trying to upgrade the memory in my HP Compaq dx2200 from 1Gb to 2 Gb. I bought what I thought was the correct memory and it fits the slot but although 2Gb appeared in the BIOS setup, it wasn't recognised in Windows. So I looked around and upgraded my BIOS and now it reports: CMOS Checksum error - Unsupported memory configuration. Power off and remove one DIMM. I took both DIMMs out and I've found that the original DIMM is 2Rx8 667Mhz, while the new DIMM is 800MHz. Is that the cause of my problem? Do I need to swap the DIMM, or is there some neat trick I can do with the BIOS (I got the latest from the HP site). I need 2Gb to run ProTools. You might have guessed that I'm a bit of a n00b. Thanks edwardo
remove the 800mhz memory chip and replace with Maximum memory as specified by Hp Compaq web site Memory upgrade Expandable to 2 GB PC2-5300 DDR2 SDRAM (667 MHz) they should be running as a pair at the same bus speed Hope it's of help to you
