Uh, I'm not sure if this thread is appropriate for this, but I trust you guys more than randomly signing up on some tech forum.
I got a handmedown laptop for free, and I'm thinking of doing a RAM upgrade on it to boost performance. Specs:
Intel Core 2 Duo T4200 - 1M Cache, 2.00 GHz, 800MHz FSB
Seagate Momentus Thin T022 - 320GB, 5400rpm, 16MB
Windows 7 Ultimate 64-bit
The RAM in question is a 1GB stick of DDR2-667 - pretty meagre considering my basement RAM usage is around 550MB, and that shoots to 800 if I ever so much as bat an eyelash at a program. I think 2GB would be sufficient, but if its practical to upgrade to 3GB, I wouldn't say no either.
My question is in regards to the importance of matching RAM - brands, capacities, speeds, etc.
Matching Capacity: Should I just add a 1GB stick of 667? Would mismatching the 1GB stick with 2GB cause any problems?
Matching Speeds: Am I right in assuming that you'll bottleneck if you try to match a stick of 667 with a stick of 800? Then, a more general question: would it be worthwhile to upgrade to 800?
Matching Brands: I think I already know this, but just to be clear: the brand of RAM doesn't mean a thing, does it?
If none of this matching stuff matters, I'll probably get a 2GB stick of 667 and call it a day, but I'd just like to get some confirmation beforehand.
Thanks in advance for your guys' help, I'll let you guys get back to discussing real PCs
EDIT: I just realized something I hadn't thought about! If mismatching capacities is a no-no, would it be better to go 2x1GB or 1x2GB (regardless of speed)?
