First, I apologize for starting another thread on RAM. I am very comfortable with RAM on any other machine, however with hearing in the past about Power Macintosh G5s and other Mac Pros being particular with RAM with thermal sensors, heat sinks, etc., I would like to ask some people knowledgeable in the area. In the past I have always purchased Crucial RAM. They seem to always stand behind their products and make a top quality product. With that said, should I stay with them as I upgrade my 5,1 from the OEM 12GB to 96GB or 128GB. I would want to get ECC since that is what it came with. Stability is the most important factor. I recall seeing some links for some RAM in the past but can't seem to locate them, but I recall someone saying it was the best place to purchase RAM for the Mac Pro (it was not macsales.com), although I would consider them as well. Thanks.
