The system is up and running but the BIOS does not appear to recognize the chip as a black edition. The OC Tuner option does not appear, and I am unable to OC anything.

Yeah I have had a lot of problems with my 1866mhz ram too, it would not accept the manual timings from the sticks themselves and used to crash constantly, even when it did make it past the post screen it would corrupt my hard drives... in the end I found out that I had to set the command rate from 1T to 2T and that solved my problem, but what a ballache! Even Asus technical support didn't know what was going on. (I would try to then flash to an updated version of the BIOS if it doesn't work and try that 1T to 2T trick again)

Also another thing which baffled me at first - when you enter a value in the BIOS, lets say ram timing of cas latency of 8 for instance, you have to press 'enter' or it wont stick. It will still say 8 but when you...

The main screen of BIOS reports the following:

BIOS version 2501 x64 4/8/2014
AMD FX-8350 Eight-Core Processor Speed: 4000 MHz
8GB DDR3 1600MHz

I tried resetting the BIOS using the mobo jumper. That allowed me to run the OC Tuner but the system froze when booting. I tried using the MemOK switch on the mobo and that got me back up and running. However the BIOS set the CPU clock to 4 GHz (stock) and down-clocked my 2133 ram to 1600.

I tend to think that the root cause is one or more BIOS settings but I am a noob to mobos with overclocking.

Any thoughts?

It will still say 8 but when you go out of the screen and back in again the value will have changed back to what it was.

To be honest the sabertooth motherboards are not very good, this is my second one because the last 'military grade' PCIE slot snapped off the board when I removed my graphics card, and I was quite gentle... now my second one's on-board sound has died, glad they have 5 year warranties but its waiting 3 weeks for a new one thats the pain.
