Gateway laptop RAM upgrade problems

by Yed_Ied Feb 7, 2009 11:36PM PST

I hope i"m doing this right. Gateway laptop MX6436. Suggested Max RAM 2Gig. I replaced the stock 512 module with 2ea. 1 Gig Modules, Nothing! I reinstalled original 512mb, normal operation. Removed 512 & installed 1ea. 1 Gig module, normal operation. Then added the added the 512 module, normal operation. BIOS confirms 1 and a half Gig's RAM. Why won't the 2 Gig's work?

You may need specific modules.

Crucial and Kingston have memory selectors to help you avoid these issues.

My guess is you tried GENERIC RAM you bought at the store and now you get to return those and order what Crucial or Kingston offer.

Another learning experience. I had never heard of the two places you brought to my attention, but I will make a note of them and try to do better in the future.

Generic RAM

However, I understand about the generic thing not working, but why would one of them be working and not both.

The answer is technical.

Just one of many reasons is the number of available chip selects available to the DIMM slots. The BIOS reads the memory configuration and if possible assigns select lines until it works or runs out of select lines.

You'll find discussions about High and Low Densitry RAM.
Since I would be duplicating web pages beyond this point, I must stop here.
