Which sadly happens quite a lot with ECC DDR4 for whatever reason.
>If you're feeling cheap and are okay with the previous generation, the Haswell/Broadwell-based T7910 is also serviceable
The T5810 is a known machine, very tinkerable, just works with NVMe adapters (they show up as a normal NVMe boot option in UEFI) and even have TPM 2.0 (!!!) after a BIOS update. Overall, they are the 2nd best affordable Haswell-EP workstations after the HP Z440 in my opinion.
>E5 v4 revision CPU
They are less efficient than V3 CPUs due to the lockdown of Turbo Boost, but then again on a Precision you'd have to flash the BIOS with an external flasher regardless to get TB back.
Forgot about Dell gimping Turbo Boost on that firmware.
Another route is the PowerEdge T440 (tower server), which does respect Broadwell-EP turbo logic without a reflash. Not quite as quiet as a workstation, though.
It's not an issue with Dell it's an issue with how the chips themselves are designed. There are buggy microcodes in the Haswell-EP series which can be exploited to unlock FULL Turbo Boost on ALL cores of the CPUs. This is NOT possible on Broawdwell-EP.
