No, I use the Kingston ValueRAM 512M PC2700 #KVR333X64C25/51. It
is really 512M module (tested on PC). Other computer (PC) shows
that 1GB RAM available when 2 modules inserted and 512MB whet one
module inserted.
But only 256MB available on my PegII with one module (instead of
512MB) and 512MB with two modules.
I'm blue...
