Hi. My old(ish) Windows ME Packard Bell has a GA6WMM7 mobo with Pentium III Celeron 700MHz processor & 64MB RAM which I'd like to max out for better performance. My specsheet gives the following info:

SYSTEM MEMORY
- Supports 2 memory banks using two 168-pin unbuffered DIMM.
- Single or double sided DIMMS with gold-plated contacts at a clock speed of 100MHz.
- Maximum memory 512 MB (128-bit technology) or 256 MB (64-bit technology).
- Supports 3.3 V SDRAM DIMMs.
- ECC memory checking is not supported

Q1. What's the difference between 64/128-bit technology, and how do I determine this?

Q2. Does clock speed 100MHz = PC100?

Q3. Is there any advantage (apart from cost) between branded and compatible sticks?

Confuson reigns. Any advice would be much appreciated. Thanks in advance.
