(New personal and team record)

Congratulations to SlashDude, Beyond and arminius :tu:

SlasheDude's latest prime should put RPS very close to taking 4th place overall by score.

Congratulations to all three of you.

Yes, yet another huge prime, the first one with more than 2M digits and our new record! :w00t:
Congrats to SlashDude!

We are now 4th by score :cool:

[QUOTE=Kosmaj;131920]Yes, yet another huge prime, the first one with more than 2M digits and our new record! :w00t:[/QUOTE] I think we should wait couple more years before we will hit a 2M-digit prime :wink:

.
 

Congrats to 3 huge primes, 2 of them bigger than the first Mersenne found by GIMPS in 1996 (2^1398269-1). The primes found by Gimps in 1997 and 1998 are around n=3M, it will be very difficult to get beyond them.

By the way, I do this comparing just for fun :wink:

A couple more "Small" ones :)

And of course Cruelty is right, I meant "our first 2M-[I]bit[/I]" prime. :big grin:

50529*2^357177-1


Found while testing my new quad core. :smile:
I bought a Q6700 when the price dropped on 21st April. Running at 3.25GHz with a vcore of 1.264V.

To lower the CPU temperature from 80c to 47c it's best to take the plastic film off the heatsink! lol

I thought it was running a bit warm. :blush:

Here are a few primes I found within last week or two for RPS;

2741*2^737586-1
2741*2^468594-1
404643525*2^379133-1

[B]Beyond[/B]

Congrats on many nice primes!

98682705*2^521820-1 is prime!

1003*2^482655-1 is confirmed prime (I re-found it just now, but according to both the [URL="http://www.rieselprime.org/Summary00300.htm"]300<k<2000 page[/URL] on rieselprime.org, it was already found by a guy called Hedges back in 2004). :smile:

A little disappointing to find that the prime was already found after the initial rush of excitement on seeing it in my results file (it would have ended a long personal dry spell for me, had it been new), but alas, that's what happens when people search k's in a hodgepodge way as was done with k=1003. :sad:

Bang:
99*2^1292395-1 is prime.

This is the right thread. You are the only one who posts primes in k<300, so you got it right this time.
We post reservations and updates there, and primes in the "post primes here" thread. Logical?

Oh, okay. I always thought you were supposed to post everything related to k<300, both primes and reservations/statuses, in the k<300 thread. But, you're right, it does make more sense to post all the primes here. :smile:

In that case, then, could a mod please move my post about my earlier k=157 prime to this thread? (It's currently in the k<300 thread.) :smile:
