The CPU test requires a processor that supports at least the SSE instructions set (every CPU since the Intel Pentium III does). The GPU test requires a graphic card that supports Opengl GL 2.0 or more.
powerMAX requires Windows 7 or later.
How to use powerMAX ?
powerMAX is a very easy-to-use utility with minimalist functions. It requires no installation, and generates no file or registry entry in the system. It does not require administrator rights to run.
CPU burn-in test
The program proposes two CPU tests : SSE, and AVX for the CPUs that support it. Depending on your CPU model, one of the two tests will generate more power dissipation and a higher temperature (please refer to the "Hardware Monitoring" paragraph below to see how to monitor the power and temperature values). The tests will automatically use all available CPUs in the system, and will cause a 100% CPU load.
GPU burn-in test
The GPU test runs a complex 3D scene designed to stress the GPU. If your system combines an integrated IGP and a discrete GPU, the discrete GPU will be automatically used for the test. It is possible to choose the resolution in a set of predefined values, and the GPU stress increases with the resolution. The test uses the maximum multisampling value (MSAA) supported by your graphics device.
Important note: if you run the GPU test in windowed modes, the maximum efficiency is obtained when the test window has the focus.
Simultaneous CPU and GPU burn-in tests
When the CPU and the GPU tests are ran in the same time, you may notice lower CPU power and temperature values than the CPU test alone, simply because a part of the CPU power is used to drive the GPU test. The more powerful your CPU is, the less you will notice that side effect.
powerMAX includes no built-in hardware monitoring features to monitor the main components health sensors. There are several options depending in what data you want to look at :
- CPU and GPU activity and temperature can be tracked with any hardware monitoring software like HWMonitor or HWMonitor PRO.
- CPU and GPU powers can also be tracked by those software, but in some cases the values reported by the component are not accurate. In order to get reliable values, or if your CPU or your GPU does not report its power, we recommend that you use a plug wattmeter (especially if you plan to run the CPU and GPU tests in the same time and wants to check the total power consumption of your PC). Alternatively, you can use one of the PSUs with built-in hardware monitoring. Most of them are supported by HWMonitor & PRO (see the list here (*)).
