I have an HP Pavilion a1620 PC. I was running two, PC2-4200, 512 MB sticks. I upgraded to a total of 4GB, 4-1GB sticks in each bank. I realize XP does not register the full 4 GB. But it does register over 3GB. The problem is in the BIOS it is registering as a total of 128MB, 32 MB in each bank and also says it is PC2-5300 which my mobo should be able to handle even tho the sticks I ordered was suppose to be PC2-4200 and says so on the labels. I have went to HP website and updated drivers for my BIOS, but has made no difference. I took out all but two of the sticks and it still shows them as 32MB sticks. Can anyone help or suggest what to do?
