Precision T3620, memory DDR4-2133 vs 2400 or 3200?
I'm thinking of buying a Precision T36200 that does not have ram. I was really surprised at the price on eBay for 2133 ram for this system? I would think I could use other NECC ram like DDR4-2400 or 3200 that would run at 2133. Has anyone had experience with this and how did it work for you?

Your system supports RAM speed up to 2133 MHz, according to Dell's specifications.
You may be able to use faster RAM, like some of those that Crucial guarantees compatible with your system, but it will downclock (run more slowly) to the maximum speed that the system supports, which is 2133 MHz.
Other brands may work as well. I listed Crucial because they guarantee that RAM to be compatible.
Whenever touching components or working inside a computer, wear a grounded wrist strap, also called anti-static wrist strap, ESD wrist strap, or ground bracelet. It's a cheap and sensible precaution. Rest the laptop on an anti-static mat or at least a reasonable alternative such as corrugated cardboard. (Repeatedly touching a metal case part is not sufficient mitigation with modern components.)

The 3620 tower workstation will support the following processors:
Intel Core 6th and 7th generations.
System memory specifications:
In my opinion, purchasing a complete system with components and OS will give you better value than gathering parts and dealing with compatibility issue but no substantiate savings at the end.
You may review these related threads to learn more information about your system.

The T3620 is a mid-tower case, not a laptop. I found a video that said the T3620 supports DDR4-2133, 2400 and 2666. But, on the Intel site it shows that the included Xeon E3-1270 V5 CPU only support 2133.
Anyone with experience with this config?

The online Precision T3620 Documentation page, "Dell Precision Tower 3620 Owner's Manual" specifies the Dell tested/validated memory sticks on page 40.

I ordered the system last night. It has a Xeon E3-1240V6, which supports 2400 ram. I found this to confirm.
Memory
Up to 64GB of DDR4 memory in four DIMM slots are supported on the Dell 3620 offering speeds of up to 2400Mhz. However, the 6th generation Intel processors only support speeds of up to 2133Mhz even with memory modules that support faster transfer speeds. Both ECC and non-ECC memory modules are supported.
I am very please with the CPU as it is actually a bit faster than an i7-7700. This system has a Quadro M4000 with a 365watt PSU to support it.
Thanks for all your input.

The system came in a few days ago. It has 2x4GB DDR4-2400T UDIMM modules running at 2133. I took those out and put in a single 16GB stick Corsair Vengeance LPX DDR4-3200 ram. It also runs at 2133. I see no place in the BIOS to change that. I looked to see if there is a jumper on the MB to change RAM speed, but didn't find one.
So, the CPU has support for 2400, but the system does not.

@Chino de Oro
This one came fully loaded to include a few dust bunnies. I had to give the interior a good cleaning. If it is lacking anything, it would be the amount of RAM. It only has two 4GB sticks, adding two more would be easy and less than $20. I pleased with the 365 watt PSU, 8GB M4000 GPU, M.2 boot device and a 4GB HDD.

It's great to hear you are happy with the machine performance. As for the memory speed, can you do a CMOS reset to see the correct speed be recognized and run at 2400 MT/s
With the machine removed from power, held power button for 15 sec. to discharge and remove residuary power. Open the side panel and locate a blue jumper somewhere at the edge of motherboard toward the bottom of the chassis. Use the jumper to short both pin of CMCLR for 5 sec. Replacing the jumper back to its original location (do not put it on service mode). Assemble everything and power up the machine. It may cycle through 3 times before the Dell logo appears. Immediately tap F2 for BIOS settings. Since the ESCD table has been cleared, you might have to adjust some settings to match hardware setup as before (it can be a good idea to take note of the settings prior to CMOS reset). But the main reason for being in BIOS is to verify the memory speed.
If there is no change to memory speed, it could be the latency of performance RAM you used. It's best to test with Dell OEM 2400.
