Hi,

Any ideas why my pc cannot pick up all the memory modules? I have 3x 2gb modules but it only picks up the 1st 2gb. Running windows 7 ultimate edition.

I've inserted each one individually and it works for each one.

Any ideas / suggestions to resovle?

thanks

x64 or x32 windows?

64bit

errm, on the off chance, have you got some more ram there you can test??

Windows 64 bit only sees 4gb, i think... but the RAM that's not seen can still be used.

Windows x32 will only see like 3.6GB however x64 will see however much your motherboard can handle! :)

other way round  eLm , 64-bit has an addressable space of 2^64 which is unimaginably huge - 32-bit is limited to 4GB but in reality you'll always get less due to graphics memory etc

 QCK no only have these 3 pieces. thought it'll be a nice triple channel but it turned on me! :<

any other ideas?

 tankza Try taking 1 stick out at a times see if you can get any increase in memory :)
