Assist in boosting AMD FX-6300 performance on Asus M5A78L-M with USB3
I believe the best approach is to turn off turbo and set the clock to 18.5/19, which should keep voltage changes low and reduce temperatures noticeably. Using smd overdrive for temperature monitoring would be helpful, though hemonitir seems unreliable in this regard.
I received your pm/video mate, but I'll post here just in case someone with the same setup needs this advice.
You mentioned you have good cooling, so we'll focus on a 4ghz clock—something the FX6300 handles easily in my experience.
Launch BIOS, go to the advanced tab, adjust the jumper free configuration, set CPU overclocking to MANUAL, change the CPU ratio to x20.00 at 4000mhz, and disable AMD Turbo Core.
That's it—leave the rest alone; the BIOS has poor voltage control options, so I'd leave it as is and save any changes.
Switch to Windows, download these three tools—they're top for stress testing and monitoring:
- hwinfo
- intel burntest (better than prime for pushing CPUs)
- amdmsrtweaker (includes two batch files to simplify enabling APM)
After installation, open hwinfo, select the sensor checkbox, click close to dismiss updates. The beta version may show some quirks.
This should display a list similar to other system info tools, focusing on core clocks #0-#5 and CPU/Motherboard temperatures under the IT8728F header.
Currently, core clocks will swing between 1400mhz and 4000mhz—this is normal because the board's BIOS can't disable auto power management.
Run Intel Burn Test, click the start button and leave settings unchanged. Wait a few seconds, then click the clock icon at the bottom of the hwinfo window. This resets the speed settings.
What we need is a consistent 4000mhz across all tabs.
It seems like intermittent throttling is happening due to the board's aggressive APM handling.
We have a solution: stop Intel Burn Test with the stop button, open APM Tweaker (should be on your desktop), double-click the off.bat file. You should see a quick black prompt that disables APM BIOS.
Clock speeds will still vary under light load (normal for the quiet BIOS setting).
Restart Intel Burn Test, click the clock icon again to reset. The CPU should now stabilize at 4000mhz on all tabs.
Continue the burn test for its full 10 cycles.
Keep an eye on CPU and motherboard temperatures in hwinfo.
Acceptable temps are around 60°C or lower for the CPU and mid-high 30s for the motherboard—your system won't face this stress under normal use.
Once the burn test finishes, you should have a stable 4ghz overclock on a budget CPU and board combo. Well done!
I wouldn't attempt these steps with a stock cooler—you might push it to 3.8 (the chip's normal turbo speed), but aftermarket cooling is the best option.
Just to clarify, I tried everything you suggested and it worked for me once, though I had to revert to defaults later.
After re-trying with instructions, it stopped working again. Whenever I turn off the Intel Burn Test, the clocks reset to 1.4000mhz. To achieve a steady 40kHz, I'd need to consider other factors—maybe lower the CPU temperature or adjust settings further.
Keep up the effort, and you're on the right track!
Performed several adjustments to the voltage settings now.
Reduced the voltage when under load, which lowered CPU and board temperatures by about 5 degrees.
Operates at 4.3ghz with a CPU voltage of 1.3375, load line calibration at 33%.
Now runs at 1.36v under load instead of the previous 1.404v during auto mode.
Hi All, I plan to purchase the same CPU and motherboard from microcenter for $110. I have a few questions:
The motherboard supports VGA, DVI, and HDMI ports. Can I connect three 1080p monitors simultaneously?
I prefer not to overclock the CPU but want to lower the clock speed slightly to achieve a cooler performance. Do you know how to do that?
Thanks.
Same configuration here, -r9270 set to 1050. I used 4.4 stable for months with tx3 Evo air cooling, and it worked smoothly during every game I played. EXCEPT h1z1 which I just began yesterday, then my PC kept crashing all the way down to 3.8. I never changed voltages, just turned off cooling and quiet mode, which led to severe throttling. I increased my memory clock to 1866 because the default was 1600 and my RAM was 2133, but that wasn’t a major issue. I could have just bought a better CPU; with a better motherboard, you’d likely reach 4.6-4.8. Even after overclocking, the CPU still struggled with high-quality streaming, so I’m planning an upgrade to a fully Intel/NVidia setup when I can afford it.
