512 MB module has gone bad


Recommended Posts


I bought two 512 MB ValueSelect DDR400 sticks in June. Everything worked fine until later October when random hard crashes started to occur. I am not overclocking; everything is cooled properly and is running at a normal speed. The crashes only proceeded to become more frequent.

What I tried:

- Checking all temperatures in my system; nothing was over 120 F.

- memtest86+ for 10 hours, which strangely revealed no errors

- cpuburn-in for 10 hours, which revealed no errors

- Switching to a different operating system; running in textmode only

- Memory tests from the Knoppix LiveCD (no errors, but they made it crash)

- Reducing the system down, one part at a time

- Moving RAM to different slots

What this eventually produced was that one particular Corsair RAM stick was causing the crashes; near the end of the testing, plugging it in would often crash the system within 15 minutes. I haven't yet run memtest86+ again because I required the computer for work and didn't want to risk crashing it at a critical time.

Please set the Dim Voltage to 2.7X volts (+.2 Volts W/Giga-Byte) and then set the timings to if you have Value Select "BY SPD" and then test the module/'s one at a time with www.memtest.org! If you still get errors, please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! However, if you get errors with both modules that would suggest some other problem and I would test them in another system or MB to be sure.
