Hey I changed the settings in BIOS, and the crash/rebooting became a lot less frequent, hours apart.
I decided to update the GPU BIOS to the latest version from the ASUS website, then cleared my drivers with DDU and reinstalled them.
Now, instead of crashing and rebooting, the drivers crashes but then recovers, which is some progress, but still an issue as gaming in this condition is out of the question.
I don't know what this means, I'm happy that the cold reboots have stopped but I'm still concerned.
Using GPU-Z I can see that the memory clock still jumps up to max but the GPU load is much steadier.
Is it possible that changing the BIOS settings as suggested in the solution you linked back to Auto would have any effect?
I'm aware it's potentially an issue with either the PSU or GPU itself but I've tested the PSU in another machine and it was fine, and seeing as their's been a relative improvement in the performance of the GPU (no more reboots) I would like to
a) Rule out driver/software issues before moving on to the hardware
b) Find out why the reboots have stopped and if there's a possible solution to the crash/recovering.
I've tested the card for a short while in game, the temperature is fine, never going above 41°C and it performed fine, right up until the crash and recovery.
Thanks again for your post and I'd really appreciate any further input you might have.
Yes, this is now the Catalyst drivers falling over - this happened a fair bit on my old system that has a 6960 in it and is pretty easy (if a little time consuming to fix). A clean install of Catalyst Control Centre should fix this but you also need to install and update the .NET Framework
before you install the GFX drivers and Catayst.
Follow these steps here and she'll be apples -

I'm glad the manual BIOS fix stopped the crashing, maybe after you get Catalyst sorted, you could try switching it back to Auto and see what happens (or if it's stable, just stop fiddling with it ha ha
)
Good Luck!
Bad news, I'm afraid
I changed my new 750W Corsair PSU for my old 500W (again Corsair, perhaps Corsair really are awful at making power supplies) and the crashing stopped completely.
I was unsure, but for 11 hours the machine ran absolutely perfect, heavy stress and no.
Then it crashed, similarly to how it had originally, a freeze accompanied with audio loop and hard reboot. I wondered if potentially the BIOS settings I had altered were the cause (I did NOT check up on this, which I definitely should have, but I was quite heartbroken that it had crashed again and am very, very tired from troubleshooting and the ups and downs of inconsistent hardware failure) so I reset the options to Auto and when the PC booted back up, it almost instantaneously crashed, this time accompanied by an ominous pink graphical error ribbon across part of the screen.
Because of this I reset the BIOS in case there was an error with the old 500W PSU, changed the settings back in the BIOS, and added increased the PCI clock to 130 just in case, and I also unplugged one of my 3 chassis fans, as I'm unsure of the power draw that is currently being asked of the 500W. I also now using DVI-D cable instead of HDMI to connect the GPU to a monitor, just because I had one available, but I'm too afraid to actually do much other than turn on the system and monitor it with HWMonitor, the last time I saw graphical glitches such as the one I saw my previous GPU was dying, with the same 500W PSU being involved at the time.
So, I'm fairly sure that the motherboard is the main root of the problems, but it seems that either one of or both of my 1-year-old/brand new PSUs are faulty, OR my GPU is faulty, but I can't determine that until I take it to a friends and test it there.
If you've any ideas on what might be occurring, keeping in mind the system (and specifically GPU) ran fine for at least 10 hours under stress, please let me know.
Soon after posting this I'll box my GPU up in it's anti-static packaging and head off to test it in a friend's rig which surpasses all the requirements.
Unfortunate that I had to meet your positivity with this crap, but what can you do. Next time I post hopefully I'll be able to confirm if it's a GPU issue, and the sticky conundrum of whether the 750W PSU is faulty, but the 500W isn't enough for the rig, or neither are an issue, but I think it may be my Asus motherboard that's the root of all evil.
Hopefully will have some useful news soon
EDIT: It may not be incredibly accurate, but using Cooler Master's power supply calculator web app, it puts my system at 567W minimum, I think I have done something incredibly stupid by playing games in max settings with this current config :/.
