Using prime95 on windows 64 bit
  

I get to a certain extent immediate rounding errors when working with the 64bit version or description of Prime95, at the same time as the 32bit version runs the similar test (blend) beneath the similar conditions and BIOS settings without several errors for hours. I immediately desire to make sure, if it's a general bug/characteristic of the 64bit version or description, or if it is incredible specific to my system. Giving the impression of being further to share any experience by means of 64bit users. So I am endeavoring to test for several instability. I have comprised and downloaded the 64bit of Prime95, and I start the test, additional than nothing occurs. I observe the entire 4 windows, additional than nothing else occurs. I have comprised and give the impression of being approximately, and have not been capable to locate out why it would not test my system. The entire of this for the reason with the intention of PCVantage 64 bit with the intention of I am endeavoring to run. I ran it stock, no happy playback, it the entire ran smooth. At present its the entire broken up.

Re: Using prime95 on windows 64 bit

For the over clocker?s, Prime95 has a characteristic called "Torture Test" by means of the intention of permit maximum pressure testing on the CPU and RAM. There are additional than a few alternative permitting the pressure test to focus on the memory, processor, or an equilibrium of mutually. Additional often than not Prime95 determine to detect an error within a substance of minutes if an over clock is not stable, on the other hand numerous people similar to let the system "burn-in" overnight to make sure long-term constancy. The advantage of this version or description is by means of the intention of it is multi-threaded and determine to mechanically manage worker threads to completely stress the entire cores of your CPU. This is the 64bit version or description for Windows XP 64bit Edition / Vista 64bit Edition / Windows 7 64bit Edition.

Re: Using prime95 on windows 64 bit

I am working by means of a Q6600 on an Asus P5K Premium by means of 4x2 GB of G.E.I.L. DDR2/800 ram. The OS is Vista64 Home Premium. The CPU is water cooled, they encompass a rest is on air. The Grfx is an 8800GTX (non-over clocked).I got the system at present to 9x400Mhz (3.6 Ghz). Northbridge is attractive up volted @ 1.55V, DIMMs at 5-5-5-15(defaulting for 800Mhz)@2.0V (not the suggested 1.9V) and FSB execution at 1.4 V. By means of CPU Voltage damper facilitated I get 1.39V on the CPU beneath load in CPU-Z. Test results (prime surrounding off examination enabled):OOCT for 2 hours - no errors, max core temp approximately 65°C.Prime95(64bit) Diminutive FFT for 2 hours - no errors, max core temp approximately 65°C Prime95(64bit) Large FFT for 2 hours - no errors, be extremely successful core temp to some extent on top of 65&#176 as I said, the surrounding of checking is facilitated in together versions or descriptions of prime, BIOS settings unchanged. The result is completely reproducible.

Re: Using prime95 on windows 64 bit

I am working with version or description of 25.6 build6. This one scales mechanically to as numerous cores as you desire. No necessitate generating multiple instances. Most recent days the 32bit version ran for 8 hours. Solitary of my four cores got a rounding error subsequent to regarding 5 hours, the additional three continued without error in anticipation of I stopped them at the morning. The 64bit version or description (25.6 build6) I ran instantaneously afterwards created rounding errors on two cores surrounded by a minute. I have comprised and been working with the 64-bit version or description of prime 95 by means of zero tribulations on the entire 3 of my systems.

Re: Using prime95 on windows 64 bit

Have you comprised to run the 64bit client at the same time as working with stock settings on the CPU and RAM. If it does not error out at stock, then its additional probable by means of the intention of your over clock immediately is not quite constant and has nothing to do by means of the program itself. In view of the fact with the intention of large and diminutive FFT's seem to be extremely well in 64 bit, I suspect a memory tribulations, in view of the fact with the intention of blend is set to stress much additional ram. I believe I encompass originate an indication to the cause. The tribulations is indeed centered approximately the memory. I have comprised 4x2GB DIMMs (working with at 800Mhz).If I eliminate two of them even the 64bit version or description runs for hours without errors. With the intention of leaves two conclusions for me my board does not similar to four DIMMs with the intention of much. The 64bit version of prime is moreover additional picky than the 32bit version or the 64bit version addresses additional/dissimilar parts of the memory.

Re: Using prime95 on windows 64 bit

A program premeditated to be utilized to locate Mersenne Prime numbers. The Prime95 is a program premeditated to be utilized to locate Mersenne Prime numbers. Mersenne numbers be able to be demonstrate amalgamated (not prime) by moreover finding a factor or by working with a Lucas-Lehmer first and foremost test. Prime numbers encompass long captivated amateur and professional mathematicians. An numeral greater than one is called a prime numeral if its merely divisors are one and itself. The primary prime numbers are 2, 3, 5, 7, 11, etc. For illustration, the number 10 is not prime for the reason by means of the intention of it is detachable by 2 and 5. A Mersenne prime is a prime of the appearance 2P-1. The primary Mersenne primes are 3, 7, 31, 127, etc. There are merely 40 recognized Mersenne primes.
