AMD FX 8320e Overclocking Help
hey guys i managed to install my h105 cooler and after some tweaking, my fx-8320e reached 4.5ghz stable. core speed is 4515.06mhz with a multiplier of 22.5 (7 to 22.5). bus speed is 200.67mhz, core voltage is 1.476, ht link is 2207.36. during a stress test with prime 95, the max turbo is off and idle is at 39c.
For a chip labeled as 8320e, it performs well.
Hi there, just wanted to share that I also have one at 4.7 ghz at 1.5 volts on my MSI 970 gaming board—it briefly jumps to 1.55 before returning to 1.5 volts. I’m using an H105 as well; the problem seems to be the lack of LLC support, which limits it from reaching 4.8. I can boot and access the web at 5 ghz, but no stress test has passed without causing a system freeze after about a minute.
Running the fx 8320e with an R1 Ultimate twin tower air cooler (considered one of the top air coolers available) and achieving a stable speed of 4.6ghz (with +0.300V offset) using high LLC is possible. Medium LLC is generally suggested because it handles voltage changes more smoothly, though I experienced instability with medium at higher speeds. However, I found that using medium LLC at the highest setting still worked well. High LLC is reliable for peak performance, but I opted for it only because I couldn't safely increase the voltage beyond +0.325V without overheating.
Using a Gigabyte 990fxa-UD3 motherboard with an aftermarket VRM heatsink (as this board is a revision 1.1 model) provides good cooling. For comparison, the R1 Ultimate reaches a max of 1400rpm under load, cooling slightly better than the H100i liquid cooler at max speed and quieter overall.
At 4.7ghz with +0.300V, stability is uncertain—sometimes it runs for hours without issues, but a worker will drop within minutes. At 4.7ghz with +0.325V, it's a risky bet; the core temperatures can spike to 67-68°C, which is why I stop it there. Changing the LLC level to +0.325 doesn't affect performance significantly.
Stable readings are around 3.2GHz at 9c idle, 24.9 under load for medium LLC, and 62.9 under load for high LLC. The safe operating limits are 62 cores (package) and 70 socket (mainboard spec), which represent consistent performance. If it exceeds these, especially without dropping workers or causing instability, it's acceptable.

1.5v is the upper limit I'd consider for vcore on an FX-8xxx CPU. A few people push it higher, but I prefer to keep at or below the recommended maximum set by AMD. My FX-8350 ran smoothly at 4.7GHz with a voltage of 1.4175v (using the Asrock 990X Extreme6 board).
