So ive been seeing a few post online, including a deleted reddit post claiming it was possible:

We know that the hardware in the Series X (and Series S to a lesser extent) is RDNA2 and of course very capable of a decent hashrate.

What some may not know is that the Xbox Series X has a 320 Bit memory bus, even the 6900 XT only has a 256 bit bus. 560 GB/s vs 512 GB/s.

So one could expect at least 60 MH/s, but likely closer to 65 MH/s. Series S would likely be around 30 MH/s.

Ive read that you can load your own apps through dev mode ($19 upfront cost), so certainly it seems like something that can be done.

Ive got a Series X that sits around not doing much 95% of the time, really want to put it to work. Anyone here know anything about this? These are very powerful and cheap rigs if this can be easily done.

I have the chance to get some Radeon 7970 cards with 6 GB of VRAM for about $50 a card.

That being said, they are GCN 1.0 and thus subject to the memory controller thrashing with the ethereum dag size issue.

Would the 6GB of VRAM alleviate that to some degree? I tried looking up info on the R9 270X 4GB (GCN 1.0 as well) and found nothing recent regarding their increased memory size in relation to the current DAG.

I can not commit to buying them if I do not know what they can do with more VRAM. Of course, they could mine Zcash and that may be what I do, since it is still very profitable.
