Announcing release: standalone memory tester for NVIDIA GPUs - Thread im FAH-Forum, evtl. gibt es bald eine alternativen Download ohne Registrierung
Der Test lief bei mir sauber durch (GTX 260 übertaktet), generiert jedoch (noch?) keinen Output ausser dem sichtbaren cmd-Fenster, der Upload der Ergebnisse hat jedenfalls funktioniert, dieser läßt sich per Parameter ggf, unterdrücken ( --bancomm) bzw. um Benutzereingaben zu vermeiden auch voreingestellt freigeben (--forcecomm).
Gewisse Parameter lassen sich von Hand definieren, wie die genau Auswahl mehrerer installierter GPUs oder die getestete Größe des Speichers und die Test-Durchläufe:
- MemtestG80 [amount of RAM in megabytes] [number of test iterations]
Aus der Readme-Datei (Hervorhebung von mir):
- "Be aware that not all of the memory on your video card can be tested, as part of it is reserved for use by the operating system. If too large a test region is specified, the program will print a warning and quit. Also, if the tested GPU is currently driving a graphical desktop, the NVIDIA driver may impose time limits on test execution such that tests over very large test regions will time out. This can be easily recognized by seeing a number of test errors larger than 4 billion, which go away when a smaller region is tested.
If you suspect that your graphics card is having issues (for example, it fails running Folding@home work units), we strongly recommend that you test as large a memory region as is practical, and run thousands of test iterations. In our testing, we have found that even "problematic" cards may only fail sporadically (e.g., once every 50,000 test iterations). Like other stress testing tools, to properly verify stability MemtestG80 should be run for an extended period of time."
- "- I have an {ATI,NVIDIA 5/6/7-series} video card and it doesn't work!
- Currently, only NVIDIA CUDA-enabled GPUs are supported. As of this writing, only the GeForce 8-, 9-, and GTX-series, the Quadro FX series, and the Tesla series of NVIDIA products support CUDA. - - I have a CUDA-enabled card, but it still doesn't work!
- You must have a CUDA-enabled graphics driver installed. See the Downloads section of http://nvidia.com/cuda to obtain a CUDA driver. - - I get an error complaining about a missing "cudart.dll" on Windows!
- This is a CUDA runtime file which we currently cannot redistribute with MemtestG80. However, a version of the file is bundled with the Folding@home GPU client; that file will work if copied into the MemtestG80 runtime directory."
