There are quite a few settings I can use in Prime95. What is the most stressful for memory?
I need to test 4GB for stability. Lets say the OS takes 800MB RAM (yeah vista x64), I run 2 copies of P95 on custom. 4096-4096 FFT 1200MB each. Is this stressful enough? Or should I use 8-4096 FFT? |

what CPU do you have?
AMD X2 - I suggest 2 copies of custom/blend test as you mentioned Core2Duo - one instance of Small FFT + 1 instance of blend test Last fiddled with by Cruelty on 2007-03-20 at 09:52 |

Its just a Pentium D 930.
I normally run custom. Is 8K more stressful or 4096K more stressful? Is setting ram to a high amount stressful or smaller amount? I know the CPU is stable. Just added some new ram and wanted make sure it runs well with the system. |

I don't have any experience with dualcore P4. I would first make benchmarks using single core and then run them again with stress test running on the second core. In case of C2D CPUs there is a performance hit when using large FFT stress test on another core, so to test stability of RAM I choose blend+small FFT, to test CPU stability alone I choose 2 x small FFT - in case of your CPU you'll have to experiment a little bit

memtest86 is a nice utility that runs outside of OS- it used to be a bootable floppy back in the day, not sure now. It runs quite a few diagnostics on your entire memory space over the course of hours. I use it when testing new overclocking settings after I am sure (via Prime95/LLR) the CPU is stable.
Google should locate a burnable bootable image to run it. -Curtis |

memtest86 seems to be the standard. Use the "+" version, because plus ussually means better
