Dell EMC PowerEdge R740xd Server Review & Overview | Memory Install Tips | How to Configure System

Dell EMC PowerEdge R740xd Server Overview | The R740xd is an enterprise 2U server packing a massive punch. In this video, we will review and outline the essential components of the PowerEdge R740xd as well as demonstrate how to properly install & configure your memory. To start with, the PowerEdge R740xd is the premier 2U server from the impressive Dell 14th Generation family. The R740xd is the next generation to the very popular Dell PowerEdge R730xd server. One big improvement you will find is the processors. Dell EMC R740xd’s are driven by dual Intel Scalable processors including Silver 4100 series, Gold 5100 & 6100 series and Platinum 8100 series. This is an LGA3647 socket. There are 24 DIMM slots running on DDR4 memory. This is the second generation of DDR4 based servers from Dell, which now boast faster speeds. The Dell R740xd has a couple different chassis styles including 12 Bay LFF and 24 Bay SFF.
The Dell EMC PowerEdge R740xd supports three types of memory: ECC Registered (RDIMM), Load Reduced (LRDIMM) or Intel Optane Memory. RDIMMs and LRDIMMs are the more common options. Intel Optane Memory is a newer technology with some amazing advancements. ECC Registered will have size options of 4GB, 8GB, 16GB, 32GB and up to 64GB. Unfortunately 128GB ECC Reg DIMMs will not work with the R740xd. Max configuration with ECC Reg is 1.54TB (24 x 64GB) DDR4 PC4 3200MHz Server Memory. However, with Load Reduced you can use 4GB, 8GB, 16GB, 32GB, 64GB and up to 128GB. The max configuration with LRDIMMs is 3TB (24 x 128GB) DDR4 PC4 3200MHz Server Memory. Your speed options are the same: 2133MHz, 2400MHz, 2666MHz, 2933MHz or 3200MHz.
Now let’s talk Intel Optane. The module sizes are enormous. 128GB, 256GB or 512GB. Extremely exciting. Speeds are a bit slower with choices of 2133MHz, 2400MHz and 2666MHz. With Intel Optane memory, the most you can load is 12 out of 24 DIMM slots with 512GB DIMMs. Unfortunately, you cannot load all 24 slots with Intel Optane RAM. Only 12 slots. Also, the proper way to install Intel Optane RAM is at the start of the memory channel. The good news is you can mix the Intel Optane Modules with load reduced modules. If you mix Optane and LRDIMMs, then the max would be 6.14TB (12 x 512GB) Intel Optane + 1.54TB (12 x 128GB) LRDIMM for a total max of 7.68TBs of memory! Yes memory! That sounds more like storage. Incredible performance.
There are two processors inside the Dell R740xd. Each CPU controls twelve memory slots, which means there are six memory channels per CPU. This equates to two DIMM slots per memory channel. To make it easier, Dell has labeled and color coded the DIMM slots, which makes it much simpler to properly install memory upgrades. Make sure to always install modules in the first slot of the channel, which is the white slot. Black is the 2nd slot. In our video, we will review the channels in greater depth and physically load the DIMMs.

Awesome. Keep the videos coming!

Appreciate the positive feedback!

Nice tips! thanks!

Appreciate the positive feedback! Have a nice weekend.

Thank you for these videos! Just pickup up one of these R740XDs LFF for the home ESX server, and love it so far. Am wondering if it'll support 6242R procs, and if I can remove the center (4) drive support to free up power for a GPU for Plex.

[@cloudninjas]

Yes on 6242R. Must have updated BIOS. Email [e-mail] on the GPU power. Thank you.

[@FloridaFrank2010]

@@cloudninjas Thank you for the confirmation on the 6242Rs! Looks like I can remove the center tray as well, long as I change the air baffle and use the taller heat sinks too, for the increased TDP of the 6242Rs. =)

DELL DR4100 NVRAM hardware has failed. Log WARNING: NVRAM PCI ControllerSuper Capacitor Voltage Low. Can you tell/show me what to do?

[@manikandanjagatheesan1282]

Does processor and memory controller are embedded?

[@cloudninjas]

No they are not embedded. You can swap them out and upgrade very easily. Thank you.

Good Day. Nice video. If I may ask, I have here a Dell R740 installed with 1 CPU and 2 x 32GB of RAM. Now i need to upgrade it by adding additional 2x32GB of RAM. Current RAM's are installed on slots A1 and A2. Then I put in the additional RAM at slots A3 and A4, but the server is unable to boot up to the OS level. It freezes on the portion where it says, "loading BIOS drivers". To troubleshoot, tried to remove the currently installed RAM on slots A1 and A2 and replace it with the newly purchased RAM and it boots fine. Just wondering if you have any solution to this. Any reply would be highly appreciated. Thanks.

[@cloudninjas]

Those are the correct slots. Might have a bad CPU... or CPU pins could be slightly off... or could be a bad DIMM slot. But you have the correct slots selected for 1 CPU configuration.

@@cloudninjas thanks for replying and confirming. We will further do the troubleshooting. Have a nice day.

Does this server have internal M.2 SSD? I wanted to install Windows Server OS on internal SSD and use it as boot drive so I can maximize all 18 drives. if it doesn't have internal M.2 SSD, can I use PCIe expansion adapter? Thanks.

[@cloudninjas]

With the Dell 14th Generation Servers, like this one, you will need to install a BOSS Controller card in order to utilize M.2's properly. The newer 15th Generation Dell Servers have dedicated M.2 ports. Thanks for your comment!
