If it shows W7 is 64 bit then any of these should work.
Dell Inspiron 1545
I'm looking to upgrade the RAM from the present 2GB.
There are two chips in the unit, I take it they are 1GB each. The only noticeable difference between the chips is the last serial number digit (one has a V, the other a W) and one has DIMM1 and the other DIMM2 on it.
The system spec states a 64 bit op system. A chap on Dell community says it will have the capacity for 64 bits but would have come with a 32 bit set up. That I find strange.
Two scans indicate that it can take up to 8GB RAM, so therefore it's a 64 bit system.
Could anyone please confirm one way or the other.?
