I am running these 3 items together and I've noticed that my computer struggles with high RAM operations... particularly a silverlight app that I use for work.

I overclocked to...
Core Speed 4099.8 MHz
Multiplier x Bus Speed 20.5 x 200.0 MHz
Rated Bus speed 1999.9 MHz
Stock frequency 3800 MHz

And its stable. Sadly, my RAM should read as:
DDR3 1333
Timing 9-9-9-24
Cas Latency 9
Voltage 1.5V

In CPU Z, however, it reads as:

Memory Type DDR3
Memory Size 8 GBytes
Channels Dual
Memory Frequency 400.0 MHz (1:2)
CAS# latency (CL) 6.0
RAS# to CAS# delay (tRCD) 6
RAS# Precharge (tRP) 6
Cycle Time (tRAS) 15
Bank Cycle Time (tRC) 20
Uncore Frequency 1999.9 MHz

Why isnt my ram performing up to specs?? How do I fix this within BIOS? What settings do you suggest?

Thank you so much
Bryan

No it doesn't! LOL. I just went into BIOS and it was defaulting to DDR3 800MHZ!? I swapped it to my specs, and disabled manual memory timings... and now it is reading as it should!

666.6 mhz, 9 clock CAS latency. YAY.

May be placebo but I am thinking it's snappier already.
