Faulty stick of CM2X1024-6400

Hello,

 

Purchased a pair of CM2X1024-6400 sticks of Corsair memory about two weeks ago, and one of them died on me this morning, which made the whole system crash hard. Computer would not boot up again until I removed the faulty stick, which gave me a headache for a bit trying to figure out what was wrong because I thought it was the motherboard at first.

 

Can I get this replaced? Thanks in advance!

Yes but 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?

Sure can. I'm a big fan of pictures, so I screengrabbed from CPU-Z:

Everything in the BIOS is set to Auto, since I'm not interested or comfortable with the thought of overclocking, despite having a nice Zalman CPU heatsink fan with some Arctic Silver thermal compound and plenty of airflow in the case (CPU sits at 34C).

 

Basically two days ago, I was playing Civilization IV and the computer crashed hard and shut completely off. I thought nothing of it initially since the computer booted back up just fine, assumed the game was the culprit and went about my business. The following day, again while playing Civilization IV, the computer locked up hard and shut off except this time, after turning the computer back on, it froze 3/4 of the way through the RAM check at bootup... don't recall where it stopped exactly, but it was somewhere in the 1600 MBish range. Just stood frozen for a good 10 minutes or so, and I decided to turn off the computer. Turning it back on resulted in the computer no longer giving a display and it was basically a giant paperweight at that point. After some troubleshooting, I narrowed it down to the second stick of RAM. The computer won't boot up with the second stick of RAM in the 1st DIMM slot by itself, but it will with the first stick.

 

Any more info needed on your end? Thanks again for the assistance.

Please make sure that you have the latest bios and then load setup defaults and set the Dim Voltage to 2.1 volts and then set the timings manually to the tested settings for the specific module you have, and then test the module/modules one at a time with http://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. In addition, with this MB you have to disable legacy USB in the bios when running any memory test.

 

With this MB I would leave the timings set to Auto or By SPD as some have reported when using the manual settings they have problems.
