AMD FX 8320 OC Problems
AMD FX 8320 OC Problems
I assembled a new setup to experiment with and also used it as a secondary workstation for my 3D modeling tasks and other projects. However, I integrated some solid gaming PC parts into the build.
It functions well and consistently achieves high scores, reaching over 70 FPS in Unigine Benchmarks and maintaining 60+ FPS at Ultra Settings. The main issue lies with my processor.
I’m running an AMD FX 8320, which is a 3.5GHz 8-core chip with an 8MB cache. While it’s adequate for most tasks, especially compared to some Intel models I’m familiar with (like the 6700K in my main rig), it struggles when overclocked. Performance drops noticeably, with stuttering ranging from minor delays to complete freezes and even BSODs.
I’ve successfully pushed it to around 5.2GHz for fun, keeping it stable and cool, but usually settling between 4.6 and 4.8GHz. I’ve tweaked the BIOS settings to suit my needs—though it might not be optimal at 4.5GHz. The voltage is set at 1.36V with no LLC changes, no overvoltage protection, no DRAM calibration, and I’ve disabled the AMD Turbo button, setting the multiplier to 4500MHz.
I’m uncertain whether this processor can handle such high overclocking, or if there’s something wrong with my configuration. I’m confident it isn’t thermal throttling since my cooling system is working well—temperatures stay below 40°C—and I have an extra set of fans installed.
Here’s a quick overview of the components:
- CPU: AMD FX 8320
- Cooling: Corsair H100i v2
- Motherboard: Asus M5A78L-M/USB3 (from an older build)
- RAM: 16GB Corsair Vengeance 2x8GB
- GPU: EVGA GTX 970
- Power Supply: Thermaltake TR2 600W
- Fans: Seven Corsair fans in the case plus two on the cooling radiator.
I'd check local classifieds if you're from a big city. Many people are switching to Intel right now, so there are plenty of FX boards available for sale.
If you purchase a brand new high-end FX board, you might be paying too much.
I'd suggest sticking with what you have, saving money, and consider switching to Intel when you can afford it. You could sell your old FX setup to help cover the cost.
Your motherboard isn't suitable for overclocking a 125w CPU. It only handles running at stock speeds, let alone boosting performance. The H100i might actually reduce performance since it prevents airflow from the board. Don't assume it's not throttling due to temperatures—you're seeing good temps because of that.

A superior motherboard might fix your issue, but I’m hesitant to spend money on something that won’t even match an i5 6400. The FX 8320 sounds like a weak choice due to its poor core design and low IPC. While extra cores help in 3D modeling, most programs aren’t optimized for AMD, which might make it less useful. If you’re on a budget, the MSI 970 GAMING is worth considering. It offers better features such as high-spec power delivery, heatsinks on MOSFETs, and a heatpipe connecting all heatsinks to prevent overheating.
