I just installed Vista on my laptop (My hard drive crashed and I had to start from scratch. I got a free copy of Ultimate from that Microsoft game crap, so I used that disk). Anyway, Ive only got 1gb of ram installed, and its running at 75%ish capacity. So I was looking on newegg to buy 2-2gb modules. According to CPU-Z, im running DDR2 @ max 226MHZ (PC2-4300). I did a search for 2x2gb on Newegg and the slowest speed I can find is DDR2 667 (PC2-5300) Can I buy this ram and will it run in my laptop, or will i need to find the slower frequency ram?
