I have a Dell inspriron n5010 i3 2.6GHz M390 with 1333MHz 2GB memory with windows 8.1 32bit Operating System.
I wanted to upgrade the RAM,
i could not find any 1333MHz 4GB memory So i bought a DIMM DDR3 1600MHz 4GB memory and installed it.
when i turned on the lap and went in to bios, it shows as total memory as 6GB. even after operating system did load and i went to my computer properties to check the RAM. as you see below,
Processor: intel(R) Core(TM) i3 CPU M 390 @2.67GHz 2.66GHz
Installed memory (RAM): 6.00 GB (2.93 GB usable)
System type: 32-bit Operating system, x64-based processor
After upgrading the ram i decided to change the system to 64bit operating system, and started to format. when i try to install 64bit the system crashes and im getting a blue screen. im really sorry to say i did not able to get the message.
i tried to run windows in 4GB ram stick yet i get blue screen error.....
when i start the mem test86 the computer get restarted.
please anyone can help me on this problem.
im sorry for my bad English... thankyou
