Nice article in general, but it also says:
"*Note:* If you are flashing an AMD motherboard, you need to put the 1.8V
adapter into the SPI, and then put the clip assembly onto that."

So is this right? 3.3v for Intel, 1.8v for AMD?

Not at all! The need for 3.3v ---> 1.8v adapter - depends not on
"Intel vs AMD", but on the model of that SPI flash chip. You see the
markings on the back of such a chip, google them, find a correct
datasheet, open it and read what's the working voltage for this chip -
3.3v or 1.8v.

I took off the cover and with reading glasses & flashlight squinted for
some time. As best I can make out I think (80% sure) my SPI flash chip is a
Winbond W25Q64JW. The print is so small my wife said it looked like braille
to her, and I thought  she had better eyesight than me. My only doubt is it
may say W25Q32JW, but like I said my best guess is W25Q64JW. Either way it
is a 1.8v chip according to the Winbond Datasheets, both of which I have
saved for reference.

Thanks for the reply. I was trying to make it too simple :-)
