RLMA2 Posted February 10, 2015 Share Posted February 10, 2015 From the JEDEC Standard 21-C, Annex K: Serial Presence Detect (SPD) for DDR3 SDRAM Modules, Document Release 6 the following definitions for "Byte 31: SDRAM Thermal and Refresh Options" bit 1. Extended Temperature Refresh Rate 1 = Extended operating temperature range from 85-95 ï‚°C supported with standard 1X refresh rate 0 = Use in extended operating temperature range from 85-95 ï‚°C requires 2X refresh rate The bit is to indicate if a 1X refresh can be used in an extended temperature range or if a 2X refresh rate must be used. The AIDA64 report reports for the "Extended Temperature Refresh Rate" item of the "Memory Module Features" list either "Supported" with the check box checked or "Unsupported" with the check box unchecked. These status verbiage does not reflect that nature of the bit being one of two choices. Per the JEDEC spec it would be more informative if the "Extended Temperature Refresh Rate" item showed "2X" or such and the check box unchecked and "1X" or such with the check box checked.

Fiery Posted February 17, 2015 Share Posted February 17, 2015 You're right, and we've fixed it up in the latest beta version of AIDA64 Extreme available at: http://www.aida64.com/downloads/latesta64xebeta After upgrading to this new version, make sure to restart Windows to finalize the upgrade. Thanks, Fiery Quote Link to comment Share on other sites More sharing options...
