So, I was thinking of upgrading my early 2009 Mac Pro 4,1 Nehalem dual Quad-Core 2.26GHz to a Westmere 12-core but before getting my hands on such CPUs I thought I’d try out a couple of x5570 2.93GHz quad-cores (lidded, fitted with washers and 5mm thermal strips, I happened to have laying...

Hi there. This is my first post on the MacRumors forums. So the problem is I got this Mac Mini from eBay a couple of days ago which I took the risk of upgrading the CPU from a 1.83 GHZ Intel Core 2 Duo processor to a 2.0 GHZ T7200 Intel Core 2 Duo processor. I followed the online guides...

Hello I have a 6.1 machine that I had upgraded with a 12C Xeon 2697v2 processor. The machine worked perfect for a month then failed. I brought it for repair (it was still within 12 months of the original purchase date). The Apple reseller is claiming that the processor upgrade voids the...
