CPU Stuck At Idle Clock Speed Under Full Load

[mr creeper]

Hey, guys, first time I've ever asked for assistance from a forum, but I'm stumped. I just bought a new case, motherboard, processor and RAM and I'm having an issue with my CPU clock speed not increasing under load.

My clock speed idles around 1400MHz [200 x7] but even when I run Prime95, there's no change in the speed in Core Temp. My VID stays at 0.8750v and CPU temp between 21 and 25c. I flashed my BIOS up to the most recent version and have tired everything I could find searching the issue online -- disabling Turbo Mode, Cool n Quiet, CE1, Core C6 and APM Master Mode; re-flashing BIOS; setting CPU & NB Voltage to Offset Mode; making sure Slow Mode is switched off; and attempting to overclock it to 4.0 with AMD Catalyst Overdrive. My set-up is:

Specs:
ASUS Crosshair V Formula-Z
AMD FX-8350 4.00GHz 8-Core [Stock Cooler]
Radeon Performance Series 2x4GB RAM R1866 [Clocked at 1600MHz]
XFX Radeon 7850 2GB Video Card [Old]
Cooler Master 600W Silent Pro Modular PSU [Old]
OCZ Vertex 128GB SSD [Old]
Hitachi 500GB 7200RPM HDD [Old]

Any and all help is welcome. I'm just hoping it's something really simple I've missed... Thanks!

did you update bios?

did you update bios?

I did, and reinstalled the update several times to be sure.

do you have amd turbo mode turned on?

I've tried it as both enabled and disabled; as well as all the other options I have listed above. Since last night, I have also done the following:
Loaded Extreme OC Profile; set D.O.C.P, stress testing showed the same read-outs [after do these first two, my internet and audio are disabled now]; enabled Xtreme Tweaking; set DIGI+ Load Line Calibration to high [they were set to ultra high and extreme already]; checked MSconfig.exe for HAL, but did not see that option, under Boot Advanced Options I clicked the Number of Processors Box and set it to 8 but no change; used utility to disable all options for core parking.

look at core voltage 0.864 that is not enough to power that CPU
