I figured that I would compile a little guide that explains how to properly run Memtest86+, Prime95, and SP2004 (A GUI version of Prime95) on a single/dual/quad core system to test for stability. If any of these programs generate an error, or other stop related messages, it generally means that you're unstable.
My dual core overclocking routine
I start out with Memtest86+ test #5 for 5-10 passes. If it passes I'll run SP2004 for 5-10 min to see if it errors. If it passes I'll run SP2004 for 12-24 hours. If it passes then you should be stable.
Important: If you get errors check the usual settings in your BIOS (cpu & memory voltages, FSB/HTT, timings, etc.) and try again. Keep your full load temps below 75C if you're using CoreTemp since the readings are typically 10-15C higher than bios/speedfan/everest reported temps. If you need additional how-to overclock advice please spend some time sifting through the threads in this forum.

[*]the floppy or bootable iso will work fine
[*]boot system to floppy or cd and Memtest86+ will start
[*]I have found that test #5 is the one that it will usually error on. On your keyboard hit C, 1, 3, 5 (enter), 0
[*]If you can complete 5 passes of test #5 try to complete at least two full passes of all default tests without errors
[*]Hit Esc when you are finished, remove the media, and boot to the OS
Please keep in mind that memtest is not the final verdict on stability. You should run it if you are testing an overclock, adding new memory or cpu to an existing system, troubleshooting OS errors that lead to memory failure, or if you have a new build.
Stress Prime 2004 (SP2004)
The GUI interface to Prime95's Torture Test which is much easier to use. Blend is the default and recommended test.
.: Single core system :.
SP2004
[*]run the .exe
[*]choose Blend
[*]click Start
Prime95 (use only if you don't wish to run SP2004)
[*]run the .exe
[*]choose Just Stress Testing
[*]choose Blend
.: Dual core system :.
Open your Task Manager (crtl+alt+del) and you should see two blocks under 'cpu usage history' with the cpu usage at 100% when running these utilities.
SP2004 Orthos Edition
[*]run the .exe
[*]choose Blend
[*]click Start
Prime95 (use only if you don't wish to run SP2004 Orthos)
[*]run the .exe
[*]choose Just Stress Testing
[*]choose Blend
.: Quad core system :.
Prime95
[*]run the .exe
[*]choose Just Stress Testing
[*]choose Blend
Orthos x2
[*]open Windows' Task Manager
[*]change the CPU Affinities of one of the Orthos processes
[*]when you switch back to the modified Orthos process, it will rescan its CPU Affinities and adjust the CPUs it will use accordingly.
Thermal grease application
Here's a pic :camera: showing the recommended method for newer cpu's. You'll find similar info on Arctic Silver's website.

There are other stability testing & burn-in apps available. Feel free to discuss your methodologies below.
