Hello, I have a question about my Asus P7P55-M motherboard. I have 2 DIMMs of 2 GB each installed on the first 2 memory slots (DDR3, 1333 MHz), but today I bought a 3rd DIMM (a 4GB one) but when I turn on the PC, it won't recognize it.
What could be the problem? It's a brand new DIMM. Thanks!!!!
The two 2GB modules should be installed in the blue memory slots. The blue memory slots are located at the end of the memory bus. Placing the two 2GB modules in these slots properly terminates the memory bus preventing signal reflection.
The 4GB module should be installed in one of the black memory slots.
Thank you all for your help! As it turns out, the DIMM was defectuous, I got a replacement one and it worked! I did however put it on the 4th slot B1 instead of B2 because otherwise the motherboard will not recognize it (Info checked on the ASUS site)! Again, really appreciate your help!!!
