Ahh PC-100 or PC-133 memory. Yes it can be fickle. As little as
a year ago I tried to upgrade such a system with "generic" sticks,
either purchased or pulled from other systems. Little success.
Originally was 512MB in 4 sticks and I was trying for the board's
maximum of 1GB. Got it to 0.75GB (2x256 + 2x128) but no further.
BTW expect to see much higher price per byte for the pc-100/133
memory compared to more current memory pieces. For example, a
quick check on newegg shows 512MB sticks of pc-133 at $50 but
more recent memory types at $10-$25 per GB.
