@ Kimball492 I went to a Computer Parts shop called Leading Edge Computers today and bought a new 8Gb DDR3 1600Mhz stick of Ram for my Desktop DAW PC, I have installed it in the PC and while I was at it I swapped out the CPU heatsink for the one that was on the ASRock motherboard, I also put some fresh Silver Heatsink Compound on the CPU too, so far my Desktop DAW PC seems to be running well...touchwood.
So now I have a spare 4Gb DDR3 1600Mhz Ram Stick I could use on the ASRock motherboard, if I can get it to boot reliably I'll have the basics of what I need to start work on building a Hackintosh.
