Bad stick of VS512MB400C3


Recommended Posts




I am running dual channel Value select 2X512. I do not overclock either. I have had great luck and no problems. I play DAoC, HL2, Doom3 and Planetside with no trouble. I just got World of Warcraft and tried to install the game. No luck. I called Blizzard tech support and they gave me lots of stuff top test. I installed and ran Wndows Memory Diagnostic....per Blizzard tech support and failed the test. I found the bad stick of memory it will fail Strides6, WMATS+ and WINVC. I kept it out and was able to install the game and play it fine. With the other good stick of 512. How do I get a RMA number and do I need to send both sticks of memory in or just one? Works great with 512 but would love to have another good stick of it.

Can you tell me the make and model of MB you have along with the CPU speed and it’s FSB as well? In addition, please tell me the bios settings you have set for both CPU and memory and any performance settings that you may have set?

When I boot up with both sticks of memory it shows Dual boot enabled and DDR333. I guess I am confused on what you mean by 100%. If I increase the FSB to 200 and back off the Multi factor to say 10X for the CPU it will not boot up. I have tried a 100 different setting. The only one I can get to work is the default.


I also have another computer same MB, but have the Corsair XMS dual channel 2X512. I run FSB 210 X 10.5 and it runs great.
