Where do I find this?

Should they go beyond 73 bits?

Yes. 57M to 59M should go to 74 bits. But since the ranges we're currently working are in the Cat 2, 3 and 4 ranges I figured we should (mostly) finish those off first, and then move up there early next year.

This https://www.gpu72.com/reports/estima...tion/primenet/ makes it look like all the 5xM are in the queue.

No more so than 41M through 44M. The Total column shows "Completed".

I actually need to update that report to reflect the work needed in the high 5xMs (and add a 74 bit column). I have done so for the Current TF Factoring Depth report already. I'll work on adding that this week.

Edit: Actually, I just updated that report.

It is scheduled to be replaced in the next hour or so. It's "hot-swappable", and one of the drives in a RAID1 set, so there should be no downtime. But... Crap happens... P.S. I seriously hate Seagate. In this case I have no choice, but when I do I refuse to buy Seagate drives.

I also avoid Seagate like the plague. If I had RAID1 with two Seagate drives and one failed, I would expect the second one to also fail before the array could be rebuilt.
I haven't bought a Seagate drive in 8 years now because about 80% of the Seagate drives I've ever had have died on me, sometimes getting replaced 3 times in the warranty period.
Not quite as bad as the Deathstars, but I still don't trust them to hold my data.
