Prime95 25.9 Build 4

Prime95 25.9 Build 4 is an intelligent tool which promises to bring much more convenience to your lives. It is a program to be used to find Mersenne Prime numbers. Mersenne numbers can be proved composite (not prime) by either finding a factor or by running a Lucas-Lehmer primality test.

A Mersenne prime is a prime of the form 2P-1. The first Mersenne primes are 3, 7, 31, 127, etc. There are only 40 known Mersenne primes. There are two ways to use this program. The automatic way uses a central server, which we call the PrimeNet server, to get work to do and report your results. Anyone with Internet access, including AOL, CompuServe, and dial-up ISP users should use this method. You do not need a permanent connection to the Internet.

The second method is the manual method. It requires a little more work and monitoring. Recommended for computers with no Internet access or with some kind of firewall problem that prevents the automatic method from working.

Major Features:

1. Prime numbers have long fascinated amateur and professional mathematicians. An integer greater than one is called a prime number if its only divisors are one and itself. The first prime numbers are 2, 3, 5, 7, 11, etc. For example, the number 10 is not prime because it is divisible by 2 and 5.
2. It has also gained a reputation for getting errors on computers which are even slightly unstable. If there is any problem with your CPU, your RAM, or the parts of your motherboard which are the interface between your CPU and RAM, then Prime95 has a tendency to fail. This is a very useful characteristic if your computer is flakey and you're not sure which component is causing the problem. If your computer can run Prime95 for 24 hours without any errors, then you can usually assume that your CPU and the parts of the motherboard which interface with the CPU and RAM, are stable and working well.
