Hi,
Around September last year, I purchased a 2 x 2gb Corsair 1600mhz Cl9 (see link) DDR3 kit (to replace the current ram) and installed them on an Asus AM3 M4A785TD-V EVO (not USB3) motherboard*.
I installed the modules and entered the timings and voltage (1.65V), and all 4gb were detected in the bios, windows, CPU-Z and SIW. Great!
However, recently, after about 6 weeks of not playing, I noticed a performance drop while I was playing Skyrim. Investigating the cause, I noticed that windows was only detecting 2Gb of ram (this may not actually be the cause of the slow down in Skyrim but this is a problem none-the-less).
So I went into the bios and noticed that all of the ram settings have been set to auto again - so i re-entered them in to see if it helped but no. I have tried each module separately in different slots and can confirm that the modules are not faulty and no one slot is faulty, however, whenever i have both modules plugged in at once, only 2gb is detected. Also, CPU-Z doesnt display the correct timings for the one that is working either.
Please can someone help! I have no idea why both modules are not being detected (all of a sudden almost!), and any advice would be greatly appreciated! Thank you!

* The rig at the time and now consists of a Phenom x4 965, Antec New TruePower 650W (semi modular) PSU, Radeon HD 6870, WD caviar green 750GB HDD. All at stock clocks.
