That setting would be the bus width (8 byte = 64-bit, 16 byte = 128-bit) but I believe if you look farther you'll see a "1000 MHz" value on that page as well.
Like many manual settings in BIOS you may have to turn an "Auto" setting to "Manual" to get more options ...
I finally found this, after wandering around like a drunk in there for a while
When I did, I followed your guide and found out that the highest stable system clock was 230MHz, that the highest adjustment possible was 425, and that the clock and the lowest multiplier would hit stock speeds at the utterly unreachable 600MHz. I thought, safe then.
After going to the next step and adjusting the multiplier back to standard, HTL back to original setting and system clock to 210 MHz, I got a large red blinking STOP and some very unpleasant beeps from Orthos. This is the message:
I can't find any 'stress.txt' file in my orthos folder, unfortunately, but I think it's pretty obvious that this MB is not suitable. OCCT and CPU-Z both report my vCore to jump erratically between a few numbers between 1.392 and 1.320, even though I have a 700W power supply. This is both when it's set to 'Auto' and to 1.4V. OCCT reported my load temperatures to be lower than stock when I ran orthos, which I suppose is because it never 'got cracking' before orthos stopped and nearly gave me a heart attack with the case speaker.Type: Small FFTs - stress CPU Min: 8 Max: 64 InPlace: Yes Mem: 8 Time: 15

A shame, really. I have just ordered a thermalright ultra extreme to really squeeze this CPU, I guess it'll collect dust until I buy a new processor.
A word of advice to anyone searching the forum or randomly reading this thread, then: all other reports about the MSI K9N SLI Platinum (and I'd assume other K9Ns) are correct. It is useless for anything but housewife computers.
I have ordered a Gigabyte PS5 which I hope will work as a temporary fix to let me tinker with this setup until I buy the next one.
