Mersenne Digest Tuesday, May 30 2000 Volume 01 : Number 741 ---------------------------------------------------------------------- Date: Fri, 26 May 2000 16:38:46 -0400 From: "keith" <[EMAIL PROTECTED]> Subject: Mersenne: Overclocking Heya, I have an athlon 700 with Asus K7V. I overclocked it to 850mhz with 2/5 cache and 2.0 volts. Prime95 runs flawlessly without errors, but there is one problem. It seems to run SLOWER. The per iteration time seems to be either the same or higher with it at 150mhz more! I dont get it. I thought when your speed went up, the time per iteration went down?!? Is it just beacuse i'm overclocking that something is screwed? Help! Thanks. - -Keith _________________________________________________________________ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers ------------------------------ Date: Fri, 26 May 2000 16:59:57 -0400 From: "keith" <[EMAIL PROTECTED]> Subject: RE: Mersenne: Overclocking - -----Original Message----- From: George Woltman [mailto:[EMAIL PROTECTED]] Sent: Friday, May 26, 2000 4:56 PM To: keith Subject: Re: Mersenne: Overclocking At 04:38 PM 5/26/00 -0400, you wrote: >The per iteration time seems to be >either the same or higher with it at 150mhz more!

Actually, the P6 family is better at factoring than LL testing, compared to the vanilla Pentium... But we couldn't set all the PIIs and PIIIs to do factoring either -- we wouldn't get much LL testing done... /* Steinar */ _________________________________________________________________ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers ------------------------------ Date: Sun, 28 May 2000 10:14:03 -0700 From: Eric Hahn <[EMAIL PROTECTED]> Subject: Mersenne: P-1 Database Greetings all, Well, the response to the P-1 database has been overwhelming... I received over a dozen respones with 2 hours of posting the request to the list... I'm still in the process of collecting and merging data into the database. However, I hope to have the first batch of data available on the Web by the end of the week!! In the meantime, I've run across a scenario for which I need some information confirmed. Not being a mathematician, and only knowing a general overview of P-1 testing, I want to verify my understading before I proceed witht he situation... I've run across a number of exponents that have been tested multiple (>1) times AND meet a special situation. The bounds for one test have a higher B1, but lower B2, then another. As an example (no specific case exists *yet*!): B1 Bound B2 Bound -------- -------- Test #1: 10000 10000000 Test #2: 25000 2500000 Test #3: 100000 5000000 Test #4: 50000 7500000 I assume that I would use both the B1 and B2 from test #3, as it has the highest B1 bound. I'm assuming this since we want all the factors of k (from 2kp+1) to be less than B1 OR all less the B1 except one which is between B1 and B2. As a result, the B2 bound is B1 dependent... Correct? Wrong? Let me know so I can add these special exponents to the database...

This is a little off-topic (not completely tho), and thought that I few of you might be interested in this... The Clay Mathematics Institute is offering $7 Million in prize money to anybody who can provide solutions to any of their 7 Millenium Prize problems ($1 Million for each problem). The problems are considered to be the hardest and greatest unresolved mathematical problems of the 20th century. They include: P versus NP The Hodge Conjecture The Poincaré Conjecture The Riemann Hypothesis* Yang-Mills Existence and Mass Gap Navier-Stokes Existence and Smoothness The Birch and Swinnerton-Dyer Conjecture *This one deals with prime numbers and is on-topic...
