So I just completed a new build and here are the specs;

Intel Haswell i5-4670k
G.Skill Trident 8gb RAM F3-2400c10D-GTX
Asus z87-A
Evga GTX 770 Classified.

The board and mobo my brother bought me for xmas cause I guess newegg had a package deal for both of them. The ram is not on Asus' list for acceptable RAM but it does work. Unforuntately I can't get it to run any faster then 1333mhz. I've oc'd the CPU to 4.2 stable no problems but the RAM i can't get it to move and its pissing me off lol. I've run XMP profiles, manually set the timings, raised the voltage to 1.65v, tried to run it at even lower speeds of 1600 but still nothing. I've updated the bios to the mobo, tried one stick at a time. IDK if its just a bad sticks of RAM but then they wouldn't run at all, right? I'm out of ideas besides returning them and getting a stick that is on the acceptable list.

Please help!
 


Memory speeds above DDR3-2133 often require bumping the voltage to the memory controller in addition to setting a higher supply voltage to the DRAM itself.

I'll try 1.665v's and see what it does... all i'll try upping the CPU oc to a bit higher... only getting 65c on stress test so i have more room to play with

Tried upping the volts to dram did nothing, raised the cpu oc to 4.5 did nothing.

But with a bad stick they wouldn't work if i tried them each alone right? they are both being read in the bios together and alone.. idk what is wrong i think i might just have to return these sticks and get something else..
 


Not the DRAM, that's should be fine at 1.65 volts. Up the voltage to the IMC by about 0.1

I can't even find the option to raise the IMC in the Asus bios. Think imma just give up on this one.

 


It's called CPU VTT
