Memory not working

[martin1]

I bought ASUS P5G41T-M LE motherboard because I wanted to install 8 GB of RAM in computer. Then I bought G.Skill F3-12800CL9D-8GBXL, but it doesn't work. In manual of motherboard it says max. 8 GB of DDR3 memory and 1333 MHz. This says in CMD, so it supports 8 GB of memory.

 

Other Hitachi kit 2x2 GB works. I checked somewhere on website if it isn't CPU limited, but it said new kit is supposed to work with CPU. I don't know what's wrong. Can someone help me ?

1600 MHz is much too fast for the G41 chipset, and these DIMM's don't have JEDEC profiles for slower than 1333 MHz. Sometimes you can get them to POST if you manually set the speed and timings, but you're best to find a set of 1066 MHz DIMM's.

I can't find new kit of 1066 MHz, will it be okay if I use 1333 MHz ?
