"Andreas Enge's CM" appears to be a Linux program. I didn't see anything Windows based.

I didn't know Leylands were "+" only. I should have paid more attention. It is even in the topic title.

Member pxp has a data table of Leyland primes here (http://chesswanks.com/num/a094133.txt). I decided to do an experiment based on two items in his table. Lines 519 and 521. (6255,1496) and...

I found your table very interesting and actually bookmarked it in my browser. I did an experiment based on it, but I won't go into it here. My results seemed to indicate 3-PRP does not mean prime....

The clock speed of this GPU (RTX 2080) when working at 100% capacity is around 1900 MHz. I don't know if this is what you're referring to.

Just for the record, I was able to get xyyxsievecl to run, like so:

xyyxsievecl -p3 -P5000 -x3 -X10000 -y3 -Y10000 -s- -M3200 -W2 -oresults.txt

The above produced an ABC file with over 3.3...

Without sieving, yes. I've done pre-seiving before, but it was for Riesel. Just by watching OpenPFGW output on the screen, I can tell it needs to be done badly. What with, I haven't a clue....

mtsieve is an archive with 27 binaries inside. There must be an error here somewhere.

Very well.

Above, someone mentions (3892,765). 3892^765+765^3892, if I understand the notation correctly. This must be the last value in a range from something lower. I understand how to use pfgw,...

Very well.

Going back through the pages, I found a Windows build of xyyxsievecl. I studied the area around page 35. It has been a bit tough to get it to run.
