ASUS P8P67 motherboard - RAM frequency issue

December 2016


I built up a new PC from scratch (i5 2400,Asus P8P67 motherboard and DDR3 corsair XMS 3 1600mhz Cas9 kit)
Everything installed properly, drivers,..etc. Upon restarting my PC and the red light near the RAM turns on, the PC reboot several times without success. I've check the BIOS and I noticed that the frequency of the RAM is 1333MHz (but as mentioned above the DDR3 strips should normally run at 1600mhz). Any solution?


  • Update the BIOS to version 1003 (with asus windows update)
  • Shutdown
  • Disconnect the power cord
  • After 30 seconds, move the clearRTC jumper the position 1-2 to 2-3
  • Wait for 10 secongs
  • Replace jumper in 1-2
  • Reconnect the power cord
  • Start your computer by pressing DEL to enter BIOS
  • Select XMP profile for the memory
  • Save and exit
  • Check the frequency of your RAM with CPU-Z

Thanks to Louc for this tip
