Great primes guys! An excellent week so far while I've been gone. :smile:

495*2^7041301 is new prime.

783*2^6993401 is prime

945*2^7036901 is prime

639*2^7006231 is new prime

649*2^7039171 is prime.

327*2^9491091 is prime!
this should make NPLB in prime score on place 6! and me holding the 5 biggest primes submitted with LLRnet on NPLB! 
Outstanding! Nice prime Karsten. One huge and one smaller target reached within 6 hours of one another.
This should now give us 1002 primes. 
351*2^8255861 is prime

kar_bon: this is a [b]new[/b] prime not yet in the Top5000, confirmed means, this is already in the Top5000 and you have verified it! the prime from the previous post is a confirmed one, because it was found by M.Curtis.

If you do not state "confirmed", it is new. Karsten will know the difference. Some people choose to put the response from the top5000 site. If it is a new prime, it will state "added". If it has already been found, it will state "already in database". Either way is fine. I realize the term "confirmed" can be a little ambiguous. Gary

421*2^7062191 is prime.
@Zach  it took me a while to get used to it too. Prime = new prime = added (to Top 5000 database) you want these critters :) Confirmed = old prime that you double checked and don't get ANY (!) recognition for [not fair I know] = already in database (at Top 5000 database) you don't want these beasts :( Have stern words to your computer and tell it to go find some new primes! 
[quote=vaughan;184219]Have stern words to your computer and tell it to go find some new primes![/quote]
Yes  I'll do that...:missingteeth: ...but  as you may noticed I'm runnin' against the IB5000server, and I'm not alone doin' that... and 'the other guy' is a real tough one  grabbin' (almost) all the primes (critters and beasts)... it's a hard world out there...

Oh no... :shock: Vaughan outruns me 10 to 1 !!! Well.. at least 5 to 1.... so I just pick up the pieces after he has ridin' over the 'knpairs' with his tremendous 'GHzpowah':batalov: 
Zach,
Just to let you know, you got a little unlucky to find the "confirmed" prime. For the 5th and 6th drives that run on ports IB4000 and IB5000, at most 10% of the effort is a double check so about 10% of the primes will have been already found. Gary

the next (hope not last) from the first 6 k's minidrive.[/quote] Nice primecongratulations! :smile: BTW, to all: if some of you wouldn't mind concentrating some resources on the first 6k minidrive (port G8000) until it's dried, it would be greatly appreciated. I would like to get this port dried before we move all the servers over to Gary's new server; the less port number overlaps we have to resolve, the better. :smile: I myself will be shifting an entire quad to G8000 in about a week or so when its current workload finishes, and I've sent an email to Gary asking him to join in as well. 
495*2^7124681 is prime (Thanks for the PM Gary).

465*2^7168051 is confirmed prime

471*2^7191221 is prime

after a long dry walk through the land of primes the raider strikes back:
351*2^9858171 is prime, from the 2nd 6 k's MiniDrive 
375*2^9367171 is prime

465*2^7220891 is confirmed prime
Whew, the 5th drive sure has been tough to find a new prime on. 
Finally, a new prime on something other than the 11th drive:
585*2^7245301 is prime 
from drive #6:
699*2^7169771 is prime 
519*2^7254711 is prime :smile:

775*2^7253411 is prime
429*2^7333151 is prime 
807*2^7318021 is prime
BTW, this gives me 200 "active" primes on the Top 5000 list. A personal goal achieved. 
375*2^9765331 is prime

Great work Ian. In the former words of Chris, "You now own 4% of the top 5000.".
Nice prime for k=375 too! :smile: 
2 primes in an n=~1700 range for k=495 at n>730K! :smile:

2 primes in an n=3K range for a 100k drive at n>740K. Very good. Nice finds Bruce!

Drive #7
909*2^7506891 is prime
this is my 12th prime out of the 20 greatest done by LLRnet for NPLB! 
drive #7 again
961*2^7529911 is prime

... and again
879*2^7568331 is prime
and the 13th for me out of the 20 greatest ones with LLRnet.

3 primes in 4 hours on 3 different drives/servers; 2 for n>749K!:
773*2^7499141 is prime 597*2^7609961 is prime :) 
From the 6th drive 4 hours before switching the remainder of my machines to the rally:
747*2^7501691 is prime

Hey Gary, I saw you put this in the k=10033000 thread by accident; I moved it here. 
Thanks Max. Now I have one:
545*2^7648121 is prime Jamers also found: 405*2^7657771 is confirmed prime

[URL="http://primes.utm.edu/primes/page.php?id=92632"]353*2^11143561[/URL] is prime! This is [URL="http://primes.utm.edu/bios/page.php?id=1389"]my[/URL] largest prime by almost 100k digits, which was 50k more digits than the largest one below that, and obviously this is also my first megabit prime. :smile: Amazing what a difference a quad i5 makes compared to a dualcore Athlon!

... and with about 40,000 digits more than the greatest prime found with LLRnet/PRPnet for NPLB so far!
Congrats! So this is now the new No.1 of the biggest primes here. (The next 7 places are mine! :grin:)

Congrats! So this is now the new No.1 of the biggest primes here. (The next 7 places are mine! :grin:)[/quote] Not sure if you're aware of this, but I found this on a private PRPnet server, run on my quad and only accessed by my quad. So then this is NPLB's second largest prime yet, and the largest found on an LLRnet/PRPnet server (and is 40k digits more than the largest found on a public LLRnet/PRPnet server). And BTW I have it set up to export its results to the NPLB DB every night. So this prime will be appearing in the NPLB DB around midnight CDT.

Indeed, it's NPLB's secondlargest prime overallsecond only to Cruelty's [URL="http://primes.utm.edu/primes/page.php?id=89030"]311*2^15816861[/URL], which was found in "extended" searching beyond the end of our first indivdiualk drive (effectively, in the current one).

After only one day at the new 6kMiniDrive with half of my Quad:

I've literally run 1000s of tests at CRUS and previously at RPS and never been able to hit a megabit one yet. Alas, I will get one in this drive at some point, whether it be in the 6k drive or with individual reservations. There will be plenty to go around. Do you suppose that is the smallest megabit Riesel prime for k<400 on the top5000 site? If so, is it the smallest for both Riesel and Sierp? That's pretty cool that one came around so quickly.

From looking at the top 5000 list, definitely yes. It's the smallest megabit prime for Riesel or Sierp with k<1213. These are the megabit primes up to his:[code] 345a 345*2^10002511 301109 L536 2010 346b 1213*2^10000991 301063 L121 2010 347 8009271*2^10000051 301039 g396 2009 348 1611111*2^1000000+1 301037 p197 2007 349 1089927*2^1000000+1 301037 p197 2006 350 32883*2^1000004+1 301036 p86 2002 [/code]Coincidentally, Karsten's megabit prime, which has a k of [B]345[/B], has an entry and current (as of this post) rank of [B]345[/B]. :smile: Congrats on the big prime! (2^1000000 has 301030 digits, so this is a full list, regardless of what n was actually used) 
533*2^7980221 is prime

This is the 1st time I've had 2 n>=750K primes in one day.
719*2^7502921 is prime 549*2^8006031 is prime It looks like Sloth has an even bigger one on the PRPnet server. A nice day for the big primes! :smile:

Submitted to the list. Any items that should be listed besides LLR and NPLB? S.

Now this is amazing! The third prime for k=577 (n=785121, 811657 and 813985) of the 5th Drive (n>600k) and all three found with PRPnet!
