Hi Ok then anyone UK based want a set of 4 matching 512k vram sims for a set of 4 256k vram sims. Also Pick could this explain why my 840 has slowed down to a crawl. I get no errors on the Mac and it is stable as a rock but thing's are taking twice as long as they were just last week. Vicki -- Quadlist is sponsored by <http://lowendmac.com/> and...
