Had the same problem. BIOS settings are fine. I eventually rolled back to OCC 5.4.16.0 A00 and CPU came back (memory overclocking didn't - but I think I've read something about that being by design). Reinstalled 1.3.60.1380 A00 and they went away again (except for the GPU). I suspect a bug in the software. I'll just sit on OCC 5.4.16.0 A00 until Alienware fix the problem.
Previously CPU, GPU and memory overclock options were showing in OCC. With the installation of the latest Command Centre (5.4.16.0) and OCC (1.3.60.1380) applications, now OCC only shows the GPU overclocking options. Have uninstalled and reinstalled both applications with OCC installed after Command Centre. Any thoughts on how to fix this?
Aurora R11, AWOC 1.3.60.1380, causes only gpu overclock options to be shown
