Does ECC RAM work in a Dell Precision T3610?

Yes, but with a catch. You can physically install ECC RAM in a Dell Precision T3610 and it will boot, but the BIOS may not actually activate error correction. Dell’s firmware often treats ECC DIMMs as standard memory, so you won’t get memory protection—just registered memory running at non-ECC timings. If you need actual ECC for data integrity, buy a motherboard that explicitly supports it.
