FX-8300 Overclocking problem
FX-8300 Overclocking problem
My FX-8300's current stable OC is 4176 Mhz at 1,335 Core Voltage (Aida64 says 1,416).
When I try to push it higher, Aida shows hardware failure warnings.
I'm not sure if Aida's readings are accurate.
My motherboard is GA-78LMT-USB3 (not great for overclocking), and the PSU is a CM G550M 550W 80 plus bronze (semi-modular).
It has 16GB DDR3 at 1,333 MHz (OC at 1546 MHz).
I'm wondering: should I rely on AIDA64 voltages or BIOS readings? Should I try further overclocking?
Thanks for your advice—I'm a beginner with AMD CPUs and overclocking.
If you're unsure, staying informed is beneficial. Outage control and managing higher TDP CPUs are important. Disable those settings—it's essential when overclocking. Make sure you understand what you're doing before proceeding. Otherwise, you risk damaging your computer.
uhh don't destroy your board. using too much voltage will likely damage it. it seems to be running around 120-125w now. keep it below 4.2 or it will fail. have you turned off APM, cool&quiet, C1E, and C6 settings? did you adjust any voltages or other settings? try running memtest86 to check for memory issues. are your CPU temperatures normal?
The 8300 works well for a little overclocking at normal voltages, but the manufacturer specifies a 4+1 power phase configuration. Therefore, proceed with caution when increasing voltage. At standard voltages—typically between 1.275v and 1.3v—you can expect performance gains ranging from 4.2ghz to 4.4ghz using the multiplier, depending on your setup. Ensure you disable power-saving features like turbo boost in your BIOS. Keep core temperatures below 63°C. Also, check if your BIOS includes a manual loadline calibration (LLC) option.
Other useful monitoring tools are cpu-z and hardwaremonitor; compare their readings for accuracy.

Ryan_78 suggests avoiding excessive voltage to prevent damaging the board. It seems the current usage is around 120-125W, and staying below 4.2W would be safer. They also ask if APM, cool&quiet, C1E, and C6 modes are disabled, and whether any other changes were made. They recommend running memtest86 to check for memory issues and inquire about CPU temperatures, which are between 60-68°C.
MisterMeow explained the situation regarding the 8300 board and power phase. He advised caution with voltage overclocks and mentioned possible performance gains at stock voltages. He also suggested checking BIOS settings to disable power-saving features and ensuring core temperatures stay below 63°C. He recommended using monitoring tools like cpu-z or hardwaremonitor for better accuracy and advised researching overclocking specifics for the FX 83xx chips.
If you're unsure, staying informed is a good idea. Ore phases offer advantages. Outage control and higher TDP CPUs are possible. Yes, you should disable them—it's essential when overclocking. It's basic knowledge to have before proceeding. Otherwise, you risk damaging your computer.
Lower power phases result in weaker power supply to the CPU. With the 8300 model having a 125W TDP, improved overclock stability comes from a superior power phase (preferably 8+2). The VRMs are heat-sinked, offering some advantage. However, the total power delivery won’t match what’s required for higher overclocks.
Your BIOS should include auto and three manual settings: low, medium, and extreme. Adjusting vcore voltages to around 1.25v–1.27v and setting LLC to medium might improve stability. This allows the CPU to draw slightly higher voltages when needed while operating at lower voltages otherwise.
Disable these BIOS settings:
- C1E state
- cpu unlock
- Core c6 state
- CnQ
Turbo Boost is very important for stability; turn it off if necessary.
The motherboard will largely dictate your overclock performance, which may not significantly exceed stock speeds. For aiming for 4.5GHz or higher, consider a Gigabyte GA-970A-UD3P. Ensure you have sufficient cooling to support the setup.

Running the CPU at a lower voltage when not under load and allowing higher voltages when needed could help.
Disable these settings in the BIOS:
C1E state
cpu unlock
Core c6 state
CnQ
Turbo Boost <- crucial for stability
This motherboard will largely depend on your overclock, which may not significantly exceed stock speeds, so gains might be limited. If you aim for 4.5GHz+, consider a Gigabyte GA-970A-UD3P. Ensure proper cooling as well.
FX 8300 is a 95W chip; at 4.2W it drops to 125W. It’s essentially similar to the FX8350 but with lower voltages and clocks.
Something like my board with 8+2 is key.
Ryan_78:
FX 8300 is a 95w chip. When you go to 4.2 then you get 125w. It's basically the FX 8350 at lower voltages and clocks.
Yeah, something like my board with 8+2 is important.
Oh, that's correct—it's 95w. I'm confused about which ones were 95w and which were 125w since there are so many 83xx series chips.
