Typically with these machines to get the in-built USB ports working requires the deletion of the AppleHPET.Kext, however, AppleHPET.Kext is also required for the CPU Power management drivers to work properly, and with two power-hungry CPUs I can bet the cost of an FL1100 based USB card would be offset quite quickly by the savings on your electricity bill. After you have cleared the old paste away on the heatsink and Die with ISO (or acetone-based nail polish remover) and before re-clipping the heatsink, be sure not to blob the paste on the Northbridge Die, as like GPU Die it's important that it's completely covered corner to corner in the thermal paste, as any exposed areas could destroy the chip.

Lastly and most importantly is that the Northbridge gets a fresh coating of thermal paste as these Northbridges tend to get extremely hot under system load, this isn't helped while it's covered in fossilized thermal paste. I unscrewed the top of the PSU and sucked the dust out with the hoover brush, I really wouldn't recommend doing this if you are not comfortable or don't know your way around a PSU, Compressed air fired down the PSU air inlets and outlets should work just as well. I would recommend stripping it completely down to its constituent parts and going from there, I find that a hoover with a brush attachment works brilliantly for de-dusting all the parts and boards. (I would recommend two X5650 CPU's if you want to follow this guide as I cannot guarantee that the power management used by my guide will work on any other CPU, but It more than likely will)Ī Mojave compatible GPU (I'm using an RX480 and I have used an RX 460 on this build as well as a Kepler based GT720)ĭue to the age of these machines, they are screaming for a double dose of maintenance.
