Why not ECC ram? Lot of AM4 boards support it.
Also, just have enough RAM, but don't disable swap. Put swap on an enterprise SSD but let Linux handle it. It will do so cleverly. Whereas with RAM only you cannot use swap at all. Minor disadvantage is you should encrypt your swap. But with modern hardware that shouldn't be a large penalty.
What, how? The only part of the chip that touches the ECC bytes should be the memory controller itself. The reads and writes going across the internal fabric should be exactly the same.
Also the PRO versions support ECC and seem to have the same iGPU.
On top of that, finding compatible ECC sticks is not easy and they can be quite pricey.

Given that was one of the requirements of the OP (integrated graphics), my point even though technically imprecise, still stands.
I have the same memory sticks. They cost £157.86 each 32Gb stick. That's over 2x the price of non-ECC sticks of otherwise similar specs.
Sounds like money well spent.
I wasn't making any value judgements though, only posting observations.
That said, it's much more likely that a faulty or low quality PSU will be the cause of that rather than the cable, and there's a lot already written out there about why a high quality PSU is important.
I replaced 2 of the 16GB ECC sticks in my main PC with 32GB ones a while ago and put them in my NAS, will probably do the same with the remaining 2 sticks to max out my RAM.
This shop [0] sells the same ones I have but it's even more expensive than it was last year, at £206.17 for 32Gb.
