The stutter/pause happens even when OCCT is idle, and on HW Monitor when OCCT isn't even running. Pretty much any situation where info from the system is being refreshed. Also when a lot of system memory is being used (OCCT with free memory enabled, Memtest HCI).
OCCT "stutter"

Try updating your BIOS

If the stutter happens even in the bios settings it has nothing to do with the gpu or windows or your hard drives. It's down to either the firmware or the cpu/ram (highly unlikely though)

I've had a look at the BIOS I've got and it's v1.9 - the latest one - but the date is different from that on the website (18 Feb vs 8 Mar). Still worth doing?
Also, I expect the update would kill my RAID 0...

It will update the RAID controller if there is an update in there. It shouldn't kill your array.

BIOS update done - turns out I put the same one in again and CPU-Z wasn't reading the date properly. Still the issue.
I'm now thinking it's the CPU, to be honest, and that I might have done something to it while changing the cooler.
It's far more likely that you damaged the board, not the CPU. It's incredibly rare for a CPU to go wrong especially if it wasn't overclocked at all.
Did you monitor the clock speeds? I had a board die on me last year and the CPU was throttling to 1ghz causing all sorts of mischief.
Clocks are all solid in OCCT and temps never go over 55.
I think I'll try some replacement memory next, as it's the cheapest thing to check (and I can sell it on if it doesn't cure things); I don't get the stutter when running CPU-only stuff like in-place p95 so it's got to be memory, memory controller or board.
I've been doing a bit more reading - is it possible that a system can be stable but still need more vcore to get the memory controller up to speed?
I've already ordered new memory (2666, in fact - the fastest DDR3 I could find), so if it's still not right I've at least narrowed it down to the board or CPU... don't know which one to root for; top-end Z97 matx boards are like unicorn sh*te, but a new CPU will be more expensive.

And would this affect how the BIOS behaves? I can see it messing with the OS, but the BIOS...?

Yes. having an unstable system isn't limited to the OS as it is a hardware problem. It's like having a super high overclock that the PC can't take, most of the times you wont even be able to go into bios, or when you go into bios it will just hang.
That's why there are those CMOS reset buttons and jumpers on the boards
Update - got some new memory and the problem persists. No harm done; I can sell my old memory on.
Couple of bits of research:
a) try increasing the IMC/VTT voltage. Does anybody know where this would be hiding/what it would be called on the MSI Z97 platform? I'm already running the vcore as high as I would like for safe temps.
b) CPU-Z reports my FSB:RAM ratio as 1:10. It's been a while since I played about with 775/1366, but shouldn't this be a lot higher? If so, how can I change it safely?
Cheers.

a) I think that IMC/VTT is called uncore voltage now
b) I don't think you can touch your FSB settings on a non K cpu... after a quick googling base FSB should be 1600 MHz
BTW, I think you do understand by now that you are trying to run memory speeds your processor hasn't been designed to support

So youre still going through this but ignored my "test it at stock" advise?
^^^As for running mem faster than CPU is designed for. Ignore that with a big laugh.

Don't want to go faster than 1333 Mhz, could cause a fire! ^_^

Isn't that value supposed to be times 2? That means that the ram is actually running at 2666Mhz
The speeds shown on the Intel website aren't supposed to be 2x
