Have you forgotten you called me prejudiced because I noted that not all people can afford to - or are interested in - paying for dual-channel memory? Secondly - who wrote "is so fucking wrong" etc? That's the language of someone looking for personal rewards by choice of how to argue.
And your posts have been 100% focused on your anger at single-channel memory - which isn't a question of any on-chip feature disablement. That's a back-tracking when cornered.
But even them are often very real questions of economy. When NVidia are making their chips, lots of chips fails the testing process and has to be thrown away. Except that it's possible to deactivate the broken cores and sell the chip as a lower-end variant. And this isn't a new concept. The original ZX Spectrum had 16 or 48 kB RAM. The 48 kB variant had one 16 kB bank of DRAM memory and one 32 kB bank. Just that there wasn't any 32 kB memory chips produced. Lord Sinclair bought failed 64 kbit chips and then bonded the address wires so that 32 of the 64 kbit that was working well ended up at lowest address. That gave him access to cheap memory chips - and the world got access to a 48 kB ZX Spectrum cheaper than otherwise possible.
Was same with old Intel chips - i486DX chips with broken floating point module had the module deactivated and was sold as i486SX chips. Then the market ended up large enough - acual users interested in buying a cheaper chip because floating point wasn't much needed - that Intel ended up having to redesign and manufacture 486SX chips that was from start without floating point.
