I have got BSOD WHEA Uncorrectable Error 6 times in the last two months. It crashes and restarts the PC.

I only have this issue when machine is under load and I'm gaming.

I have tried updating all the drivers (all good), chkdsk (all good), and mdsched (all good)

Not sure if that RAM is compatible, but the Asus site doesn't list that particular Corsair part as technically tested to be compatible with that motherboard (there are a number of 1600, 1800, and 2133MHz parts on the list, but not this particular set). If you've tested the RAM to be stable already, then it's an L2 cache issue with one of the CPU cores, and the CPU is at fault and should be replaced - the MTBF is rated for 75,000 hours at 40C for most pre-Haswell i-series parts, but regularly living above that can cause a *significant* reduction in expected lifetime, even a few degrees can shave thousands of hours off of that per year - for example, a part with 75,000 MTBF hours at 40C would be expected to have less than 8,000 hours if spending large amounts of time at 70C.
