This is a GFN21, GFN22 and DYFL 10 day challenge. The last one for the 2021 challenge series.
Dec 7th 07:00:00 UTC to Dec 17th 06:59:59 UTC.
No bunkering, only tasks DL after it starts will count towards the challenge.
 
If a prime is found, it will be a BIG one.  Good luck.

EDIT: This is a 3AM EDST start time

Ready to go.  It's been a while since I found a prime...fingers crossed for a big one.

Tested, Locked, and Loaded. Big Mega Prime to to be had.

Doing just that Bill.

Thanks guys.  
I survived, everything went well. Well enough to send me home after.
Will have to take it easy for a few days, no lifting ect.
I have to make a few lifestyle changes, eat better, lose some weight, exercise ...
 
Ok I fired up a few tasks, still plenty of time to get some tasks in.
Good luck, hope one of us finds a prime.

We are in 7th place and holding.

Back to 6th now.
I stated CPU but they are showing between 3 and 5 days to complete.

Same here but will add my last 6MT AVX tonight for an ending.
I have my current 8MT on my 3 X299 Rigs FMA3
Odd how they change when they start out but end back at FMA3
