Overclock stuckness
Overclock stuckness
I’m attempting to get through this without causing any major issues.
I’ve reviewed the instructions and watched the videos, I understand the potential risks. I feel confident enough about what I’m doing to ensure that no unnoticed mistakes are being made.
The hardware details are as follows:
- Asus 970 Pro Gaming / aura
- Fx 6350
- MSI Raiden R9 270x GPU
- 2Gx4 DDR3 sticks, 1333 MHz recommended later
- 500 GB SSD
- Windows 8.1
- Evo Hyper 212 with a single fan
- BIOS and drivers updated recently
My CPU is an Intel 8750, which previously limited me to around 200 MHz. After weeks of slow performance at about 3.9GHz, I decided to give it another shot before reverting to older settings.
For testing, I ran a Prime95 small stress test for 30 minutes with fans on high.
Stock settings opened the case.
After applying changes and starting the test, I reviewed some screenshots:
- One showing a load increase
- Another displaying Vcore readings
- A third with idle temperatures and multiplier values
Later, I noticed a significant jump in the Vcore voltage reported by hwinfo:

It seems the voltage fluctuated between 1.356 and 1.404 with multipliers rising from 20.5 to 21.5.
I also checked the CPU manual voltage settings:
- At 39°C load, Vcore was 1.404
- Idle temps ranged from +2°C to 16°C
- Load increased to 41.3°C with a multiplier of 0.5
The screen captures at the end of the test show consistency in readings.
Regarding the CPU voltage, I adjusted it from auto to manual and observed a drop from 1.356 to 1.392, then to 1.404 with a further rise to 1.404v under higher load.
For idle performance, I saw a jump from 41°C to 42°C with a multiplier of 0.5, reaching 4214 MHz.
When the multiplier reached 23, the system crashed immediately.
Now, about the Vcore value:
- In BIOS, it was set to 1.428 on manual mode.
- If I switch it back to auto, will that match the reported voltage?
- Should I set it to the maximum value shown during stress testing (1.440+)?
I’m also curious about the memory setup:
- I have 4x DDR3 2200 sticks, 1333 MHz recommended later.
- Using these could risk damaging my motherboard if not handled carefully.
I didn’t change anything else except the BIOS settings, and everything seemed stable until the Vcore readings changed.
Unless you modify FSB/BCLK, processor overclocking won't be impacted. The correct RAM stick positioning is specified in the manual, indicating that RAM should be placed in A2 and B2 slots. You might need to reset your CPU OC because you'll likely have to reconfigure CMOS to properly identify the new RAM. When determining your CPU's maximum limit, it's best to first test the RAM limits without overclocking the CPU, then combine both settings.
Do you require a vcore of 1.428 to operate at 4.4 Ghz? If you adjust the CPU manual voltage to 1.428 in Bios, is that the voltage being reported by hwinfo or should you set it to the maximum value shown for the stress test of 1.440+? I understand there might be a voltage spike at startup or at the beginning of the test. You're looking to determine the highest clock speed achievable under a 65°C load while staying within the thermal limits, and you're curious about the reported voltage to begin with.
