I also recall him saying that redoing P=1 only makes sense when you choose B1 >= 10 x (B1 value during the previous run on that exponent).

So, maybe we should view this as in how much time (in...

My machine is about 3 years old. The money I spent at 16 Gb at the time I have now spent on 64 Gb of RAM. That I believe is money well spent. It will repay itself in a short time due to a lesser...

Now that we are close to the target set originally, to get under 20,000 unfactored candidates per one million range (or 2,000 per one hundred thousand) and now that 30.8 has changed the landscape I...

Using the P-1method and version mprime 30.8 on a 64 GB machine I found a factor for M9509161.

The factor itself is a rather normal one: 493379850346175773054490527.

The fun is in the factoring...

With the new 30.8 version I decided to upgrade my RAM from 4x4 Gb to 4x16 Gb. The cost in 2017 of 16 Gb total was the same as 64 Gb now.

My current system is 4 years old. It is based on a Z-170 Asus motherboard. At the time 16 Gb of RAM (4 x 4 Gb) was the sweet spot. So I re-evaluated it and today 64 Gb (4 x 16 Gb) costs the same as...
