I have an ASRock P4i65G 1.00 motherboard purchased and installed in 2006. Belarc Advisor print shows I have 1gb installed memory 512 x 2 in slots 0 and 1, and slots 2 and 3 are empty. The motherboard book says it can take up to 2gb memory. How do I find out precisely what type of memory I have which in slots 0 and 1? I have lost the invoice for that memory and I believe I must install 2 more 512mb of exactly the same type.
Absolutely brilliant, thanks to both of you. The Crucial site offers several compatable solutions from scrapping my 2 x 512 and replacing with 2 x 1gb, to a choice of two different 2 x 512mb dimms to add to my existing. I can't see the point in scrapping what I have so I may as well use up the remaining slots. The board won't take more than 2gb anyway. Thanks again.
On second thoughts for the sake of £19 difference, I might be better off taking a matching pair of 1gb each, than adding slightly different dimms of 512mb. That is what I will do. Thank you very much for your brilliant assistance.
