I went ahead and took the liberty of reserving that exponent to 91 bits. It's a comparatively slow 100 days on my GTX 1080, but it will be good to have an exponent fully factored. I will check my local electronics store for a 3060 Ti tomorrow morning, which should give a faster ETA at an affordable price.

Perhaps I should say fully factored...to the optimal 91 bit depth! A factor would at least avoid the arduous P1 and PRP tests, but those will also be an interesting challenge.
I was lucky enough to get a 3060 Ti this morning, despite there being over 100 people in a line that started forming the day before! I will install that and see what the new ETA is.

It isn't reflecting on mersenne.ca yet, but I factored 3321928171 to 91 bits with no factor. Anyone with a Radeon VII Pro who is willing to crunch a P1 and PRP test is good to go!

Now you can get to mining ETH with that thing.
