Hello, yesterday i took my computer to the store and installed evo 212 on xeon x3450 cpu, before that i was using stock cooler and it was heating a lot so i had to change it, the ram was working fine for a year+ now, but now since pc got back i can only yse 4gigs, ive tried to resettle the ram sticks and went to msconfig (was already unchecked) and still only 3,99GBs being used, im using win 7 64bit.
Rams are 100% on correct slots, im using 4x2gb, they’re on same spots like they were before the new cooler.

Specs:
Motherboard: P7P55 LX
Cpu: Intel Xeon x3450
PSU: (not so familiar with PSUs but on this one it says 580w and 20w frequency, so idk is it 580w or 600w)
GPU: AMD Sapphire 7870 HD
RAM:
2x2GB of corsair xms3 1600MHz
2x2GB of Zeppelin 1333 MHz

(The frequencies are different but it worked without a problem earlier)
 
Solution
your mixing 1600 with 1333 ram, make sure that 133 is first ion slot A1-A2 and 1600 in slot B1-B2 if you mix 1600 & 1333 in paired slots it will cause issues. make sure the 133 is the first set of ram in the board and not the 1600 otherwise it may not read the second set of ram properly
