Hi, I have an I7 920 build I put together right when that processor launched, it's gone through a few upgrades over the years such as an Intel 128 SSD when they first came out, with the newest upgrades being a 2TB mechanical hardrive, Windows 10, and an EVGA GTX 1060 6gb gfx card. PC still works great; however, I'm pretty sure the power supply is making a funny noise and I plan on replacing it before it fries my system. I figured while I replace the PSU, I will take the whole thing apart and give it some much needed TLC (aka cleaning). A PSU upgrade is pretty standard, but I was recently reading the"1366 x58 Xeon Enthusiast Overclockers Club" thread and I was inspired to maybe upgrade to a Xeon chip as they seem pretty cheap used. The motherboard is an EVGA E758-TR 3-Way SLI (x16/x16/x8) LGA 1366 Intel X58 ATX Intel Motherboard. I was researching online and I'm not thinking it's compatible with a Xeon processor. A few questions: Is the motherboard compatible? What would be the best ~50$ used 1366 Xeon to use if compatible? Do i need to buy new RAM (like ECC ram) . Currently i have 6 gb of GSkill 1333 DDR3 Would I need to perform a PC back-up and re-install Windows after a processor change? Or can i just drop it in and start the PC as normal. Any advice would be appreciated. Thanks in advance.
