Yeah, It's totally random when buying memory for Pegasos1. Makes it a lot of easier if it's tested to work on it.

In my quest for a 512M or bigger mem, I found that it's a lot of easier to find smaller working mem.. but no matter if it's small or big, it never works with pairs :)

I even ordered one quality Kingston ram, which was reported to work here on Peg1 mem compatibility list, but it didn't work. Apparently memory manufacturers use different brand of chips even for same model of their memory modules.

The I finally got lucky and found working 512M module from my friend's stock... Kingston KTC-PRL133... but I'm not selling :)
