memory - Might my Acer laptop be limited to 2GB RAM? - Super User


i have older run of mill acer aspire 4720z laptop 2 years old , came 1 gb of pc-5300 ram.

i purchased 4 gb of pc-4300 in 2 sticks , when plug them both in computer bios recognizes 4 gb of memory, windows vista crashes bsod boot-up progress meter displays, 100% consistency.

i tried each 2 gb stick individually , each boots fine; ran memory test on 1 of them , passed fine. tried each 2 gb stick 1 of original 512 mb sticks , bdod's @ same point.

i have 2 hour round-trip drive return ram, 4 gb not somehow usable (i can make use of it... 3.5 gb usable, anyway).

it seems if windows or laptop has problem more 2 gb ram - or possible?

according can find laptop model, supports 2gb or ram. listed on acer support page , crucial memory selector. going intel's specs laptop chipset, gl960, lists 2gb max of ram well. looks that's issue is.

i'm surprised though computer recognizes ram , crashes windows rather ignoring ram.
