Power plan on high performance? Motherboard BIOS updated?
Yes, my power plan is on high performance and I have the latest BIOS update. Thanks for replying though!
Cool N Quiet disabled in BIOS?
The BIOS needs to be new enough to recognize the FX-8350 and set the basic frequency and vcore voltage. Under heavy load the CPU is designed to run at the base frequency. Turbo mode is only used when the CPU is under less than full load. You might want to use OCCT or similar to record the CPU frequency, temp, and vcore voltage. If your CPU isn't running hot, the mobo VRM could still be running hot and throttling the CPU. Make sure that the temp readings that you are reading are for the CPU internal temp, commonly called "core" temp. Some BIOS allow adjustment of the CPU and other PC fans. Make sure these BIOS fan controls are set to 100%.
For my FX8350:
CPU FSB: 200 MHz
CPU Ratio: Auto (7 to 20.5)
Minimum: 1400 MHz (7 x 200 MHz)
Maximum: 4100 MHz (20.5 x 200 MHz)
In your BIOS you should see:
CPU FSB Frequency: 200
Adjust CPU Ratio: Auto
I don't understand how you are even getting 1320 MHz. At the default FSB of 200 the minimum speed you should see is 1400 MHz.
