I recently bought a new pc altogether and recently realized this problem ( don't know if it was there from the beginning but my dad says when he first checked it there wasn't any problems).
I have two 4GB Corsair 1600 MHz ram sticks (CMX4GX3M1A1600C11) and my dad says until recently they were both working fine. now when i went into the BIOS i realized that it said one ram was running at DDR3 1600 and the other at DDR3 1333. It said total system memory was 8192MB 1066 MHz DDR3. checked CPU-z and it too said i had 8GB 1066 MHz. i checked the SPD .my numbers should be 9-11-11-30 but they were 7-8-9-20. i entered the numbers and apart from my CPU idle temp increasing by 10 degrees and fan noise increase , nothing happened. i then found out that XMP was off (auto). so i chose XMP profile 1 (DDR3 1600 9-11-11-30 1.5v).the computer failed to boot . then i turned it off and without touching the spd forced the memory to run at 1600.it again failed to boot.installing the memories one-by-one also reported the same numbers(one was 1600 the other 1333). should i return them and get a replacement?
