Quick CPU

Quick CPU is a Windows utility from Coderbag for tuning and monitoring the processor. It controls core parking, frequency scaling, turbo behaviour and power plans, and it shows live temperature, clock, voltage and power readings. Most people who search “quick cpu” are gamers. This page looks at it from the CPU mining side: running a CPU miner around the clock on a Windows PC and keeping the chip cool, stable and efficient.

Be clear about what it is not. Quick CPU is not a miner and does not touch the miner’s own settings such as huge pages or MSR registers. What it does is help you control how Windows and the processor handle a sustained full load. On Intel CPUs it can also set power limits and voltage options, where the BIOS allows them.

Quick CPU at a glance

What it does

• Core parking: a slider sets what share of cores Windows may park, from 0% (park as many as it likes) to 100% (never park).
• Frequency scaling: sets the minimum processor state, the lowest clock the CPU drops to when demand falls.
• Turbo boost policy: decides how aggressively the CPU boosts, which affects heat and power under sustained load.
• Power plan management: lets you create, edit and compare Windows power plans side by side, including the Windows power mode (best battery life, balanced, max performance).
• Hybrid scheduling: picks which cores (P-cores, E-cores or automatic) receive long-running and short-running threads on Intel hybrid CPUs.
• Intel advanced settings: PL1/PL2 turbo power limits, turbo ratios, Speed Shift energy-performance preference and FIVR voltage offsets, with custom profiles that can be applied at startup.
• Live monitoring of package temperature, clocks, voltage, power and per-core load, plus charts and data export.
• A stress test with Basic, SSE2, AVX, AVX2 or AVX-512 workloads, a duration you choose and optional thread cycling to find a weak core.

How miners use it

Set up a power plan for a dedicated mining PC

1. Create a new power plan in Quick CPU, or copy an existing one, so your everyday plan stays untouched.
2. Set core parking to 100% to stop Windows parking cores. This matters most when the miner does not use every thread or runs at low priority.
3. Raise the minimum processor state if clocks keep dropping between jobs, then press Apply.
4. Use Power Plan Compare to check exactly which settings differ from Balanced.

Cap package power on an Intel rig

1. Open the advanced Intel settings and note the current PL1 (sustained) and PL2 (short) values.
2. Lower PL1 in small steps and watch package power and temperature in the monitor while your miner runs.
3. Note the hashrate reported by your miner at each step. Lower power usually means less heat, but where the best point lies depends on your chip and the algorithm.
4. Save the values as a custom profile and enable auto-apply. Coderbag notes that most of these settings revert after a restart, deep sleep or power-off.

Check stability after undervolting

1. If your Intel CPU and BIOS allow FIVR voltage offsets, change the core offset in small steps only.
2. Run the built-in stress test (AVX2 if supported) for 30–120 minutes and watch for errors, temperature and clocks.
3. Then run your miner and check for rejected or invalid shares before you leave the rig unattended.

Watch thermals during a long run

Keep the tray popup or chart view open while XMRig or another CPU miner runs. Sustained package temperature and power tell you more than a short benchmark does, especially in small cases and on laptops.

Install and first run

Quick CPU needs 64-bit Windows 10 or 11 and .NET Framework 4.7.2 or newer, which recent Windows builds already include. Install it, open it and leave it running for a minute so the monitoring readings settle before you change anything. It is a Windows-only tool, so Linux CPU rigs need other tools.

Some options are greyed out depending on the platform. Power mode is unavailable with legacy plans such as High Performance. Intel power limits and voltage controls only work if the BIOS has not locked them, and AMD processors get monitoring and Windows power settings but not the Intel-only section.

Coderbag warns that voltage and power changes can void the CPU warranty, and too much voltage can damage hardware. Write down the original values first, change one setting at a time and keep the application running if you rely on monitored settings. For the miner itself, XMRig’s own docs cover huge pages and MSR tweaks; Quick CPU does not do those.

Limitations

• Windows only. No Linux version, which most dedicated CPU rigs and mining operating systems use.
• Not a miner and not an overclocking suite for AMD. Advanced power and voltage control is Intel-only.
• Many low-level settings reset after a reboot unless you use a profile that applies at startup.
• BIOS locks on many recent Intel systems block undervolting from software.
• Core parking and power-plan tweaks mainly change how Windows schedules load. They will not turn an inefficient CPU into a profitable miner. Profit depends on your electricity price, hardware and coin prices.

Quick CPU vs alternatives

ThrottleStop is the common comparison for Intel power limits and undervolting. It is aimed squarely at Intel tuning, while Quick CPU puts more weight on Windows power plans and monitoring. Process Lasso works on process priority and CPU affinity rather than the power plan, which is useful when a miner shares a PC with other work. ParkControl is a simpler core-parking toggle. Quick CPU combines parking, power plans, monitoring and a stress test in one window. For memory timings on ASRock boards see ASRock Timing Configurator; the miner itself is XMRig.

FAQ

Is Quick CPU safe?

It is a known Windows utility from Coderbag. Most of the risk comes from what you change: voltage and power-limit edits can cause instability, so change values gradually and get the installer from the official site.

Is Quick CPU free?

There is a Free edition for one PC. The paid Pro editions cover more PCs and add data-bar colour customisation, so it is listed here as shareware.

Quick CPU vs ThrottleStop?

ThrottleStop focuses on Intel power and voltage tuning. Quick CPU covers core parking, Windows power-plan editing and comparison, AMD monitoring and a stress test as well.

Quick CPU vs Process Lasso?

Process Lasso manages process priorities and affinity, while Quick CPU changes power-plan and processor settings. Some users run both.

Does Quick CPU increase mining hashrate?

Not directly. It can stop clocks dropping or cores parking under load and help you find an efficient power limit, but the hashrate itself comes from your CPU and miner settings.

Does Quick CPU work on Windows 11 and AMD Ryzen?

Yes, it supports 64-bit Windows 10 and 11, and recent releases improved Ryzen monitoring. The Intel-only advanced settings do not apply to AMD.

What are the best Quick CPU settings?

There is no universal preset. For a mining PC, start with core parking at 100% and a dedicated power plan, then adjust power limits while you watch temperature and your miner’s hashrate.
