G.SKILL sniper 2400 mhz on Sabertooth 990fx

[Sebastian_4]

cant manage to make this gskill sinper to work on my computer, i got the sabertooth 990fx rev 2.0 and a amd 8350k, all stock values not OC, i bought the 2x8gb kit (16gb total) and the higher speed i can set without crashing is 1763 mhz with OC tweaker ON and all the other options at auto except for the dram voltage that i set at 1,65 trying to get near the 2000 mhz, can they really run at 2400 mhz? this are the modules F3-2400C11D-16GSR CL11-13-13-31 at 1,65v PC3-19200 XMP ready

4 x DIMM, Max. 32GB, DDR3 1866*/1600/1333/1066 MHz ECC, Non-ECC, Un-buffered Memory
Dual Channel Memory Architecture
* Due to CPU spec., AMD 100 series CPUs support up to DDR3 1066MHz. With ASUS design, this motherboard can support up to DDR3 1333MHz.

So depending on your motherboard, one of the above speeds.

it was a CPU limitation, already check and the motherboard manual says that supports up to 2400 mhz on few QVL(that i just luckly bought one of the list) but it wont go further than 1866 due to CPU limitation.

Well, what I quoted was from the web page for the motherboard you have. So someone at Asus knew about that 1866 limitation.

To run 2133 or 2400 will probably need a OC on the CPU 4.3 or so, try enabling DOCP and select 1866 or 2133 and make sure DRAM voltage is 1.65 and raise the CPU/NB voltage to 1.25 and try. The 8350 at stock is only rated to 1866 (and testing was done with 2 sticks at 4GB each. With an OC these CPUs are capable of higher, I run a 8370 with 32GB of 2400

already got it at 2133 with 9-11-11-31 1.60v thanks to "gskill support" user, more than that requier to oc the cpu and i dont need that right now, i´ll stick in 2133 for a time and try to get some extra speed when i feel that my rig is getting old for the apps/games i use, thank you all, you were great!
