Windows thinks I have 32Gb of RAM installed
Bizarre. I've got 4GB of DDR. Here's a screenshot:
Any ideas?

First, reboot your computer, look at bios screen, and see if the bios thinks you have this memory.
The max memory support on this mobo is 4GB. Do you have 2-2GB modules, or 1-4GB? Also what type of memory - be specific on ddr, ddr2, ddr3, voltage, as much info as you can provide.
That's correct. Oops, and I meant a max of 1GB per slot. What if you pull two banks, test, then pull two other banks and test. I would like to see if it's the memory or something in the OS.
Perfectly normal with CPUZ, don't forget x2 for DDR. In addition to Windows reporting it wrong, your ram is only running at the equivalent of 316 MHz, which is slower than PC2700/333. That could be due to a chipset limitation that downclocks PC3200/400 to PC2700 speeds when all four banks are full. It can be run at the full PC3200 by essentially overclocking the ram speed, but can also introduce instability. If it is that speed due to the four bank limitation I would leave it alone.
One thing to do while you're in the bios (can also check with CPUZ) is that the CPU is running at a FSB of 200.
Yeah, Bus Speed: 201 MHz according to CPU-Z.
I've just took two of the RAM sticks out. The BIOS memory test said 2097152k, but Windows now thinks I've got 16GB installed! It's as if it thinks each stick is 8GB.
As for your four bank limitation suggestion, it's not mentioned at all in my motherboard manual. There's merely this small note:
"Due to standard PC architecture, a certain amount of memory is reserved for system usage and therefore the actual memory size is less than the stated amount. For example, 4GB of memory size will instead be shown as 3.xxGB memory during system startup."
Says it supports up to 4GB, and dual channel 400/333/266/200.
Try resetting the WEI,
Windows Experience Index - Reset
just to see if there is something in it that has gone wonky.
