Will Crucial ECC UDIMM DDR4 work in my motherboard?
Only if your board and CPU support unbuffered ECC memory. Many consumer boards won't use the ECC feature, and servers that require registered RDIMM sticks won't accept it, so check your motherboard's memory support list first.
- Module type: UDIMM is unbuffered; don't mix it with RDIMMs.
- Speed: it may run slower if your platform caps memory below 2666MHz.
- Matching: pair it with the same part number when adding capacity.
- Quantity: confirm the price is for a single 16GB stick.
