Hello,   Looking at Intel's page, it seems the fastest speed supported by the 4216 is 2400 MHz.   [IMAGE]   [URL]
Hi all.My R640 config is: 2x Xeon Silver 4216 + 12 rdimms 32gb 2933mhz 2xRank (6 dimm per proc, 1 dimm per channel). BIOS version 2.10.2  iDRAC Firmware Version 5.00.00.00 Can't get the working memory frequency at 2933 megahertz. Through the idrac interface in System Profile Settings> Memory Frequency, the setting with a frequency of 2933 mhz is present, as on pic [IMAGE] but it is not in the BIOS interface, there is only 2400 mhz. An attempt to change this parameter through idrac gives a warning and fails and hardware inventory shows the same working 2400mhz. [IMAGE]   The user manual for both r640 and xeon 4216 in turn confirms that this configuration is supported.  [IMAGE] [IMAGE]     Can you advise something?
