Blako Posted January 7, 2009 CID Share Posted January 7, 2009 My pavillion a1524n came with 1 GB of samsung DDR2 PC-4200 and one open slot for another stick. So I bought Corsair 1GB DDR2 PC-4200 to add in. (Part # VS1GB533D2) The Samsung works in slot 1 and slot 2. The Corsair works in slot 1 and slot 2. But If I put them both in at the same time bios says slot 2 is empty no matter the combination. The board is rated by HP for 2 x 1GB of ram. I'm wondering if the HP motherboard has some weird setting preventing this from working or if it's proprietary. Your thoughts? Quote Link to comment Share on other sites More sharing options...
coknuck Posted January 7, 2009 CID Share Posted January 7, 2009 When I put in Ram I always use matched ram from one maker. I don't mix. Quote Link to comment Share on other sites More sharing options...
Blako Posted January 7, 2009 Author CID Share Posted January 7, 2009 Yes, that is preferable but it does not explain the second slot going invisible on me no matter if samsung or corsair is in slot 2. Quote Link to comment Share on other sites More sharing options...
Buntz Posted January 7, 2009 CID Share Posted January 7, 2009 Try running Memtest 86 with both stick of ram in and see what it says.It will tell you on the top left side corner how much ram it sees. Let it run for a while to see if the ram errors. Quote Link to comment Share on other sites More sharing options...
Blako Posted January 7, 2009 Author CID Share Posted January 7, 2009 Tech support pointed me away from Corsair They said Kingston or Samsung ram works. The Bios says slot 1 unoccupied, slot 2 1024MB. Or vice versa. Cpu-z sees both sticks of ram. HP only has 3 compatable ram brands that work! I don't want to buy another HP. Close the thread, lock it up, toss into the abyss and give me my refund.
