8320E at 4Ghz Unstable
8320E at 4Ghz Unstable
CX500w
Gigabyte 970A DS3P (actually only 4+1 power phases)
8Gb ram at 1866MHz
8320E
GTX 960 with 4GB
Hyper212 Evo
Struggling to achieve stable GHz performance; currently I'm at GHz with Vcore 1.3, using regular LLC mode. APM and HPC are off.
The motherboard only offers auto, regular, and extreme for LLC, so I chose regular. Extreme caused excessive compensation for voltage droop.
Running at 3.8 GHz leads to BSOD with lower voltage. I’m stuck—can boot fully and run Cinebench at GHz, but Prime95 eventually fails.
Is this due to incorrect settings or just bad luck with the silicon and power phase configuration?
Appreciate any advice!
The FX8320E should handle stocks speeds when using the stock cooler on that motherboard. The 212 causes issues by restricting airflow from the VRMs. The CX500 is somewhat unstable but not severe enough to affect performance in your configuration. Follow the advice of the redneck and adjust the BIOS settings to "auto" to test. The maximum turbo speed is 4.0ghz, though the CPU will rarely run at that level continuously.

Am I making a mistake or is this just bad luck with the silicon, combined with a 4+1 power phase board leading to instability? I don't want to crank the voltage too high on this board because of the power phase issue.
Any advice would be greatly appreciated!
Your motherboard isn't ideal; we should check your power supply. But we should be able to help you get stable on the 95W 8320E at stock settings. The first step I'd suggest is booting into BIOS, set everything to Auto or use the "set optimal defaults" option and exit. Then we'll see if performance issues persist, and we'll proceed slowly. I'll also need to know what your PSU is like.

The CX500 is a fairly unstable PSU, but it isn’t severe enough to significantly affect performance in your configuration.

The motherboard’s power phase and insufficient VRM cooling are notable drawbacks (especially the lack of VRM cooling). With a faulty PSU, overclocking won’t be possible; you’ll need a better PSU if you aim for that. You might partially offset the cooling issue by adding an intake case fan on the side panel to increase airflow onto the VRM. The more air you can direct onto it, the better the performance will be.
