I just bought a 4GB DDR3 1333 Apacer RAM, but my PC is unable to boot if I have it inserted with my Kingston DDR3 2GB RAM...I am able to boot with only my Kingston RAM inserted but unable to boot with my Apacer RAM inserted with or without the Kingston RAM inserted...

Specs -
Windows 7 32-bit
AMD Radeon HD 5500 Series 1GB
Pentium(R) Dual-Core CPU E6600 @ 3.06GHz, 3066 Mhz, 2 Core(s), 2 Logical Processor(s)

I'm a noob at this LOL

I actually got the right stick, the mb box says it's compatible with DDR3 1333 RAM sticks, and that's what I got, I even made extra sure that the employee of the shop I bought it from knew what sticks were compatible with my motherboard..

could it be that since I only have a 32-bit OS that it can't handle more than 4 or 6GB of memory? or should I fiddle around in the BIOS setup and change the voltage or something??

I tested it on my friends SU, which also has the same motherboard as I do, with the same result - unable to boot if I have the 4GB stick inserted with or without the old RAM stick...
