Sabretooth 990FX and Kingston 4x4 KHX1333 memory issue

[trey915]

I just purchased the Sabretooth 990FX mobo and got everything hooked up. When I powered on it beeps constantly and the LED next to the MemOK button is lit constantly. I pressed the button and it went through the various attempts to use the DIMMS. I tried each DIMM separately to see if maybe I just had a bad DIMM. I looked in the manual and it says that Kingston 1333 DIMMS should be compatible but it gives a different part number. I am using the KHX1333 from Kingston. Has anyone else tried to use these successfully or is there something I need to do to get them to work or am I just going to need to purchase new DIMMs?

Thanks/

Hi trey915 and Welcome to ROG

If you do not have the latest Bios then I suggest you first update then set to default.
Should the Bios still fail to recognize your DIMMs, then to save a lot of time and frustration, Swap them out with ones listed on the QVL.
