VMT v1.5.112 is out - Video Memory Stress Test

[®®®]

Misha has updated his tool from v1.4 to 1.5.112

CUDA (instead of DirectX) testing is new as well as a link to his homepage.

Here's the descriptive changelog:

Main difference from my old tool Artifact Locator is per-bit testing (almost per-pixel), what allow to escape of usage of GDI and make possible to use the bit masks almost color masks.

Now tests in different color modes performs in "background", without changing current video mode.

Now no any "show": only two progressbars and simple digits of the results. In testing process the results field will filled by different information, video RAM error messages has following view:

Error at [01ABCDEF]: must be FFFF, but found FFEF (bits: 0000000000010000)

Also after detection of the error will be increased counter "Errors found". All other messages in results field is information-only and do not say about video RAM errors.

On videocards with hundreds megabytes of video RAM full test set can to work many hours. Express-test can be performed by selecting value "Small" or "Express 15%" in field "Test set". First variant does not test memory with walking bits. Second one performs test with all patterns, but process only random 15% of created surfaces (different for each pattern and not less then one in any case). "Small" test set is good for quick check of overall memory integrity, "Express 15%" is better for quick stability test after overclocking.

Except testing via DirectX, now program can to test video RAM via CUDA interface from nVidia company. Dropdown list "Test type" allows switch test method. Beyond selecting "CUDA" item test options panel will change its view and will contain two new dropdown lists. With "Device" list can be selected one of available video cards, and "Memory block size" list contain available values for one memory test step. The CUDA technology at this moment supported only nVidia GeForce 8xxx and 9xxx series cards.

IN THE CURRENT PROGRAM VERSION THIS TEST TYPE HAS BETA-STATUS AND IT CORRECT WORK ON YOUR SYSTEM DOES NOT GARANTED.

Thank you Misha :)
