New Features
-
Due to the high number of failures reported for the Hammer Test (Test 13), the algorithm was revised to perform 2 potential passes:
- Row pairs are hammered at the maximum hammer rate. (ie. no delays between each row pair hammer)
- Row pairs are hammered at a lower hammer rate (200K per 64ms, as determined by memory vendors as the worst case scenario)
- If memory errors are detected in the first pass, error details are not immediately displayed to the user and the second pass is started. If errors are detected in the second pass, they are reported as normal.
- If errors are detected in the first pass but not the second pass, a warning of potential high frequency bit flips is displayed to the user.
- The premise behind this revision is to better inform users of the significance of errors detected in the Hammer Test, as opposed to a strict PASS/FAIL result. Although errors detected in this test are real errors, the conditions needed to induce these errors occur only very rarely in normal PC usage, and should not be of concern to most users. Therefore, a warning rather than an outright failure would ensure the user is aware of the issue and be able to take the necessary measures to mitigate the issue.
- The details of the errors that were detected in the first pass of the Hammer Test but not during the second pass can be displayed in the report by specifying the configuration file parameter 'REPORTNUMWARN'. This parameter represents the maximum number of warnings to display in the report file.
-
New configuration file parameter 'AUTOMODE' for full automation. Enabling this parameter shall result in the following:
- Splash screen is skipped and the tests are started immediately
- When the tests are completed, the report is saved to disk automatically
- System is rebooted
Fixes/Enhancements
- Shortened the test time for Hammer Test (Test 13) by reducing the total number of hammers per row address pair
- Fixed issue with the main menu not displaying for certain EFI firmware. Due to the fact that many EFI firmwares require the use of the obsolete ConsoleControl protocol to switch between graphics/console mode, the graphics/console mode workaround is now enabled by default.
- Fixed bug with details of empty RAM slots being displayed when using SMBIOS memory device information
- Added Intel Skylake ECC support
- Updated Jedec manufacturer ID list for displaying the vendor name from RAM SPD. Fixed Jedec manufacturer ID lookup function to support > 7 continuation codes.
- Fixed AMD Hudson-2/Hudson-3 SMBus support to include various hardware revisions
- Various system info related updates/fixes (SPD, CPU)
