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.

DELL T7600 Workstation
The Dell Precision T7600 is a workstation featuring an EATX motherboard with dual LGA 2011 Sockets. These only currently support the E5-2600 first generation processors, but it has the same chipset as the T7610 which received support for the second generation processors so it seems they may soon get support if Dell puts out a BIOS update. The system has 16 DDR3 slots with support for up to 16GB RDIMMs or 32GB LRDIMMs. The T7610 received support for 64GB LRDIMMs so it seems that if the T7600 does get the update for the second generation E5 processors then the 64GB LRDIMM support may come with that update as well. The workstation features 4 hot-swappable bays that can easily accommodate either 3.5" or 2.5" drives of either SAS/SATA. The system comes standard with a PERC H310 RAID controller to handle the hardware RAID configuration.
The Precision T7600 has 5 PCIe slots available if you are only utilizing a one-processor configuration but adds two more PCIe slots if you add in a second processor. All slots are full-height, full-width, but the first and the third slot under the processors only operate at x4 speed instead of the full x16. The workstation features dual gigabit networking ports with Intel adapters: 82574L and 82579LM. The maximum capacity of a single processor configuration with RDIMMs is 128GB and with LRDIMMs 256GB. In a dual processor configuration, the maximum addressable capacity is 256GB with RDIMMs and 512GB with LRDIMMs. Maximum single stick capacity is 16GB RDIMMs or 32GB LRDIMMs.
The Precision T7600 has a few known issues that have been addressed with BIOS updates:
Revision A07 fixed several major issues including:
- Non-bootable SAS drive/RAID when LSI 9265 is installed - Hang during POST when two K5000 cards are installed. 5. - RAID ONE BSOD issue.
Revision A04 Fixed an issue with the diagnostic LEDs
