I recently bought a Hitachi PC-133 128MB SDR-SDRAM from a local vendor in Hong Kong. It is going to be used in my new AMD system. Since I am a beginner-intermediate computer user, this is my first time building my own computer system. So I was wondering if that extra HKD$40 I spent to buy this piece of RAM is any better than a generic piece of RAM. I bought the Hitachi 128MB for HKD$395.
It only matters if you expect the ram to perform at 133 and if you care about your computer not freezing up.
If such things are important to you, pay the extra money to get a good name brand.
Most of the people in this forum with freezing up and instability problems when using AMD motherboard are probably using really cheap, generic ram.
If you want your computer to run great, you have to put great hardware in it.
Buying generic parts is a gamble (especially memory). You might get lucky and get a generic part that performs flawlessly, or it could be a piece of s#!t. If you buy name brand you know it will work.
The chances of a name-brand module failing are less than 1% (the chances of any given A-grade memory chip tested by the manufacturer failing are about 0.1%; there are 8 chips on a module, and many brand-name memory manufacturers do their own testing in addition to the manufacturer's test) while the chips that end up on generic modules may not have been tested at all.
Like some have said, you can get lucky with generic RAM. But you're much better off with a brand-name. You'll get better stability and sometimes, slightly better performance.
