  • Dell PowerEdge R720 versus the R720XD rackmount server

    Both the Dell PowerEdge R720 and the Dell PowerEdge R720XD are 2U rackmount servers. These rackmount servers have the capability of running Intel Xeon E5-2600 series and Intel Xeon E5-2600v2 processors *You must have BIOS revision 2.0.19 update or later installed to use the v2 processors. These rackmount servers also offer twenty-four DDR3 slots for RDIMMS, LRDIMMs, and UDIMMs.

    The R720XD weighs in at just a few pounds more than the R720 due to its significant increase in Hard Drive Bays. The R720XD has a few different options for hard drive bays and can hold a staggering twenty-four two and a half inch hard drives or twelve three and a half inch hard drives while the R720 can only hold a maximum of sixteen two and a half inch or alternatively eight three and a half inch hard drives.

    For v1 processors, BIOS revision 1.4.8 upped the maximum frequency supported to 1600MHz for both RDIMMs and UDIMMs when using one or two channels at either 1.5V or 1.35V. BIOS update 1.4.8 also upped the maximum default frequency to 1333MHz on a three DIMMs per channel layout for both RDIMMs and LRDIMMs.

    While moving up the BIOS update chain, if you are using BIOS update 2.0.19 you will be able to use the Intel Xeon E5-2600 v2 processors and also the LRDIMM will support 64GB because in a patch released before the v2 processors were even compatible they released an update (BIOS update 2.1.2) that made that possible. In a later update (BIOS update 2.4.3) LRDIMMs at two DIMMs per channel will have its max supported memory speed upped to 1866MT/s for 32GB.

  • General Motherboard Compatibility Guide

    Here is a chart I have created that will function as a quick cheat sheet for people to look through and determine processors that may be compatible with their motherboard based on which chipset it uses. Just click on your motherboard's chipset and it will drop down with the associated Code Name, which processors are potentially supported and which type of memory it uses.  Note that this is not an absolute guarantee that a certain processor will be compatible. There are simply too many variations to guarantee compatibility for anything but it is a good place to start. Please check your manufacturer's website to confirm any compatibility issues if you are uncertain. If you find any errors or think I should add anything to the chart you can leave a comment below or email me at [email protected] I will be looking to add more individualized looks at each chipset in the near future.
