Ich hab hier mal ein paar Speichertestprogramme zusammengetragen.
In der Regel reicht es aus 2-3 Programmen, z.B. memtest86+ (sehr gründlich), 3 D Mark 2005 und evtl. noch Windows Memory Diagnostic (schnelle Ergebnisse bei Fehlern) zu benutzen. Auf eines alleine kann man, muss man sich aber nicht unbedingt verlassen, wobei ich generell davon ausgehe, dass ein System nach 48h memtest86+ ohne Fehler als stabil bezeichnet werden kann. Ausnahmen bestätigen die Regel - ich erinnere hier gerne an die DDR1 Infineon Chips die da waren BE5(BE-6 und CE5/CE-6 die memtest ellenlang stable liefen aber in 3D Anwendungen erst ihr wahres Gesicht zeigten und zum Teil viel früher Fehler produzierten.
Windows Memory Diagnostic (Microsoft)
http://oca.microsoft.com/en/windiag.asp
„The Windows Memory Diagnostic tests the Random Access Memory (RAM) on your computer for errors. The diagnostic includes a comprehensive set of memory tests. If you are experiencing problems while running Windows, you can use the diagnostic to determine whether the problems are caused by failing hardware, such as RAM or the memory system of your motherboard. Windows Memory Diagnostic is designed to be easy and fast. On most configurations, you can download the diagnostic, read the documentation, run the test and complete the first test pass in less than 30 minutes.“
memtest86

„Memtest86 is thorough, stand alone memory test for x86 architecture computers. BIOS based memory tests are only a quick check and often miss many of the failures that are detected by Memtest86.“
memtest86+
http://www.memtest.org/
„Based on the well-known original memtest86 written by Chris Brady, memtest86+ is a port by some members of the x86-secret team. Our goal is to provide an up-to-date and completly reliable version of this software tool aimed at memory failures detection.“

„ctSPD ermöglicht das Auslesen des Serial Presence Detect EEPROMs von SDRAM-Speichermodulen und prüft die darin enthaltenen Daten. Diese Daten sind in der PC66-, PC100- beziehungsweise PC133-Spezifikation festgeschrieben und für eine korrekte Funktion eines SDRAM-Speichermoduls erforderlich. Die Analyse der Daten erfolgt unter Berücksichtigung der aktuellen Spezifikation von Intel (PC SDRAM Serial Presence Detect (SPD), Revision 1.2B) beziehungsweise der korrespondierenden JEDEC-Spezifikation (JEDEC 21-C Page 4.1.2.5). Fehler, die das Programm meldet, stellen in der Regel Verstöße gegen die genannten Regelwerke dar.“

MemTest @ HCI Design (läuft unter Windows)
http://hcidesign.com/memtest/
"MemTest is a RAM reliability tester. It evaluates the ability of your computer's memory to store and retrieve data accurately. A correctly functioning computer should be able to do both these tasks with 100% accuracy day in and day out. A computer that fails these tests, perhaps because of old hardware, damaged hardware, or poorly configured hardware, will be less stable and crash more often. Even worse, it will become even less stable over time as corrupted data is written to your hard disk.
By running MemTest you can ensure that your computer's RAM is correctly functioning. It is wise to test this when you buy a new computer, install new RAM, or change the configuration of your machine (for instance, to overclock it). Are the sort of user who likes to push the performance of your machine to the edge? Relying upon whether your machine will boot after your new BIOS tweaks is a poor way to determine the safety of your new settings. Use MemTest as a true test of stability."

Before this test packet was created there was no proper software for measuring vital system parameters such as CPU/Chipset/RAM providing steady and reliable (reproducible) test results and allowing for changing test parameters in a wide range. Vital low-level system characteristics include latency and real RAM bandwidth, average/minimal latency of different cache levels and its associativity, real L1-L2 cache bandwidth and TLB levels specs. Besides, these aspects are usually not paid sufficient attention in product technical documentation (CPU or chipset). Such test suite, which combines a good deal of subsets aimed at measuring objective system characteristics, is a must have for estimating crucial objective platform parameters.
RMMA provides you with the following platform information:
CPUID info, including CPU vendor, model and core name, family, model and stepping numbers, supported instruction set extensions, cache and TLB features;
Chipset (Northbridge and Southbridge) vendor and model name, AGP features, installed RAM type/size, current RAM timings;
Memory SPD (Serial Presence Detect) info, including module type/size, manufacturer, part number, attributes and timings;
Built-in RMMA microacrhitecture tests let you determine the most important low-level platform characteristics, which include:
Average and peak real RAM bandwidth;
L1/L2/L3 data cache size and hierarchy (inclusive/exclusive);
Average and minimal/maximal L1/L2/L3 data cache/RAM latency;
L1/L2/L3 data cache associativity;
L1-L2 and L2-L3 data cache bus bandwidth, data arrival delays;
I-ROB (instructions reorder buffer) depth;
L1 instructions cache size (including the "effective" size) and associativity;
Decode efficiency of various simple x86 (ALU/FPU/MMX) instructions;
D-TLB size and associativity (of each level);
I-TLB size and associativity (of each level).
