Hello,
I have a q6600 machine (Win 10 x64) with 2x1gb of DDR2 ram.
I wanted to upgrade and I wonder if it's better to buy 1x4gb stick and use 1gb of the old ram or buy 2x2 and not use the old ram (mobo has only 2 slots).
The old ram is 667mhz and the new ram is 800.
Thanks in advance and sorry if I don't respond right away because it's close to midnight at the time of posting this.
