FX6300 4.2 overclock help
FX6300 4.2 overclock help
Hi there
I'm trying to push my Fx6300 CPU to 4.2 right now. I've read many instructions from this forum, but I'm still struggling to get it correct.
Some users have had their 970a-ds3p (rev 2.1) run at 4.3 or 4.4 with that board, though they suspect something in the settings might be off—even though it's currently set to 4.2. When Prime95 runs, the cores seem to go straight through to BSOD. What went wrong?
I turned off these options:
Turbo OFF
Cool & Quiet OFF
C1E Support OFF
SVM OFF
CPU Core Control AUTO
Core c6 State OFF
HPC Mode (OFF) or enabled?
APM OFF or enabled?
Voltage Settings
CPU VCORE +0.080V
NB CORE (AUTO)
DRAM Voltage 1.500V (AUTO)
Vcore Loadline Calibration (AUTO)
Some say to enable or disable the Vcore calibration—please advise what's correct.
Even at 4.1Ghz with Prime95, it keeps failing!
Greetings
Ricardo
P.S.: The PC is planned to be upgraded in mid-2018. I'm considering a Ryzen 1600 with a new motherboard and graphics card, but until then I'd like a small performance boost.
Increase core voltage to +0.04 and aim for 4.1ghz, Cool and quiet, C1E and C6 can all be enabled again.
What CPU cooling are you running? You need to list your exact memory specs by brand, amount of modules, speed, etc. and model #s? I see you are using an offset Vcore, does your Gigabyte BIOS settings allow you to use fixed Vcore voltage?
stock cooler performs well at 4GHz under optimal conditions with ambient temperatures near 20°C and strong case cooling. 4.2GHz exceeds its capabilities. A slight increase of +0.08 in CPU voltage raises the load voltage beyond safe limits for the stock cooler and the board itself. It's advisable to study overclocking thoroughly before proceeding.
the stock cooler performs well at 4ghz under ideal conditions with around 20c temps and strong case cooling.
4.2ghz exceeds its capabilities.
The slight increase in voltage (+0.08) raises the load beyond what the cooler can handle, which is also excessive for that board.
It’s recommended to study overclocking thoroughly before proceeding.
Interesting observation: others with identical CPUs, coolers, and boards achieved stable 4.2ghz, yet mine fluctuates.
Could you assist in getting it to 4.1? Which settings should I adjust? If I use AMD OverDrive and set voltage to 1.35, it remains stable. Should I avoid overclocking via BIOS? Many guides seem contradictory.
Based on the current mobile setup and lack of recent gigabyte am3 board use, the situation seems off. The core voltage is at +0.030. Adjusting the load line calibration to high is recommended. Set the multiplier to 20 (for 4ghz) during operation. Verify stable boot. Enable overdrive and switch to the CPU status tab. Also activate cpu-z and keep it active in the CPU section. Record the vcore values for Overdrive and CPU z, as they may differ. Perform a prime test and note the voltage reading from CPU z during the test. Make sure all clocks are maintaining 4ghz (small variations up to 3995 are acceptable). Provide these details and I’ll assess whether 4.2 is plausible.
Generally speaking, considering the current situation on mobile and not having used a gigabyte am3 board for months, the values seem inconsistent. The Vcore is +0.030, the load line calibration has been adjusted to high, and the multiplier should be set to 20 (for 4ghz) during operation. It’s important to ensure stable booting at that setting. Enable overdrive, switch to the CPU status tab, and also activate cpu-z, keeping it on the CPU tab. Record the Vcore readings in both Overdrive and CPU Z sections—they may differ. Perform a prime test and note the voltage displayed in CPU-Z during the test. Make sure all clocks are maintaining 4ghz (small fluctuations up to 3995 are acceptable). Please inform me of the thermal margins observed during overdrive while the prime test is running. Cone back with this data, and I’ll let you know if 4.2 is a realistic possibility. I followed your instructions! VCore [Normal], Load Line [Auto]. Used Overdrive to set Vcore at 1.32. Prime95 [ON] HwMonitor shows under load around 1.28 to 1.29. CPU Status: Clock/Multiplier fluctuates between 4.0Ghz and 4.018Ghz (multiplier set via BIOS). Thermal Margin is 20.4c towards 20.5, with minor swings between 19.2 and 19.1. CPU FX6300 Package Temp [50] – CPU temperature 58°C [138°F]. TMPIN 2: 50°C [122°F]. I’m puzzled by the discrepancy—how can the CPU package read 50°C while the motherboard shows 58°C under load? Also, after stopping Prime95, the thermal margin drops to 40.2 with fluctuations between 40.1 and 45°C; how is that possible given the load? Please clarify this.
Due to the cpu working hard, it's running at 50°C under load and 30°C when idle. The thermal margin is measured from the maximum temperature of 72°C. The thermal margin for 20°C is 72°C minus 50°C, which means the cpu is around 50°C. You didn't follow my advice about settings. What I mentioned was to adjust the BIOS: set the CPU core voltage to +0.03, enable high load line calibration, and keep overdrive at its default level. This check helps identify differences between the stock voltage in overdrive and the load voltage shown in cpu-z. If you notice a drop in voltage during load (VDRO), it may lead to instability. You can raise the stock voltage to fix this, but it will cause higher voltages under heavy loads. Alternatively, lowering the stock voltage and adjusting the load line calibration will only increase the cpu voltage when under heavy load.
The CPU is running at 50 under load and 30 at idle. The thermal margin reflects the CPU temperature compared to its maximum of 72 degrees. For a 20°C overdrive, the temperature should be around 72°C minus 50°C, which places it at about 50°C. You haven't adjusted the settings as I mentioned. What I advised was to change the BIOS settings: set the CPU core voltage to +0.03 and enable high load line calibration. Overdrive should remain at default. This check helps identify differences between the stock voltage in overdrive and the load voltage shown in CPU-Z. If you notice a lower voltage during load (VDRO), it may cause instability. Raising the stock voltage can fix this but will increase the voltage under heavy loads. I followed your instructions, so the new values are VCore [+0.020] and Load Line [Extreme]. The results show fluctuations around 4.0Ghz with minor changes. CPU status indicates clock/multiplier variations between 4.0Ghz and 4.018Ghz, with the multiplier set to 4.0Ghz via BIOS. Thermal margin is stable at 20.4°C toward 20.5, with slight fluctuations. The CPU package temperature is 58 degrees (138°F), and TMPIN 2 reads 50 degrees (122°F). Overall performance remains consistent. It’s a minor issue; if it drops to 4.1, it should be fine. If you plan to upgrade, adding more case fans would help, especially with two on the front and back and one at the bottom—this setup should keep things cool without needing watercooling.
