We have an R730 that we're putting 2x E5-2699v4 processor in (SR2JS), along with 512GB RAM (16x32GB DDR4 PC4-2400T) (2x 1100W PSU's)
We have updated the BIOS to the latest (2.3.4).
_____________________________________________________________________
When using 1 CPU in the server, and 8 DIMMs, the server boots up fine.
Swapping the CPU1 for CPU2, with the same configurations (1 CPU + 8x 32GB DMIMs), boots fine as well, so it somewhat tells me its not the CPU's and the memory we're using that are the problem.
______________________________________________________________________
If i then take the second CPU, and put it in socket 2 (so 2 CPU's are in use), and use 4 of the 8 DMMs from the first CPU testing setup (so I know they work), into the second CPU DIMM slots..
so: (CPU1 + 4 DIMMs then CPU2 + 4 DIMMs)
The server then boots up with a multi-bit memory error in DIMM_B2. If we boot again, the memory error goes to B1 and then alternates sporadically.
________________________________________________________________________
Sometimes the R730 will boot all the way to be able to get to OpenManage with this configuration (Eventually after the multi-bit error occurs on the LCD screen, the server tries to continually configure itself and finds a configuration good enough to boot), but in OpenManage, it shows B1 & B2 DIMM Slots as having no memory there, which I suspect it disables to help it to still boot?
Mind you, these errors (B1 and B2) are coming from DIMM slots that have memory in them that was just tested 'Good' while in the server when it had the single CPU setup + 8 DIMMs (so I don't believe it to be the memory DIMMs that are bad since they work fine with 1 CPU.)
___________________________________________________________________________
I also tested some DDR4-PC4-2133p RAM, and it works good until we start to populate multiple 4 or more slots, it throws and error.

All firmware is updated and BIOS updated.
It has an H730 RAID Controller in it.

What am I missing? On Dell's website configurator, the option to choose 2x E5-2699v4 processors, plus 16 x 32GB 2400T DIMMs is an option there, so this set up should work. Plus I saw a review on a storage website, where they used this same set up with no issues (aside from having to update the BIOS)
___________________________________________________________________________
I originally thought it was a motherboard issue, but we put 2x E5-2620v4 processors in the machine, with all of the same 512GB 2400T of RAM (16 x 32GB), and it operated just fine. So it took the lower end processors with no issues.
____________________________________________________________________________
If we put 2x E5-2699v4 processors in there with all 512GB, it throws a Mutli-Bit error, and then tries to continually configure the memory, but eventually just shuts down.
This system isn't covered under Dell Warranty unfortunately as its from Canada. I try to search the Service Tag on their site and nothing comes up, so Calling Dell isn't really an option for me.
Any help you can provide or insight, I would greatly appreciated
