This reminds me of my ASRock motherboard, though this was over a decade ago now. The actual board was one piece of hardware, but the manual it shipped with was for a different piece of hardware. Very similar, but not identical (and worse, not identical where I needed them to be, which, naturally, is both the only reason I noticed and how these things get noticed…), but yet both manual and motherboard had the same model number. ASRock themselves appeared utterly unaware that they had two separate models wandering around bearing the same name, even after it was pointed out to them.

The next motherboard (should RAM ever cease being the tulip du jour) will not be an ASRock, for that and other reasons.

For the love of everything though, just increment the model number.
