I agee with John. I just loaded up my dual G4 with 2GB of RAM from Chip Merchant and so far so good. Their warrenty states that if at any time the RAM fails due to an upgrade, that they will replace it. They are also cheaper than anyone else I found. -Thom John Baltutis wrote: > My choice of vendors is Chip Merchant ><http://www.thechipmerchant.com/>, but they're based here in San Diego, so >getting to them isn't any chore for me.
