Lenovo D20 메모리 혼용 안됨

PC3L-12800R 16GB 메모리가 중고 사게 나왔길래 하나 사서 빈 슬롯에 끼우고 켜보니 부팅이 안되는군요~

Your computer has 12 slots for installing or replacing DDR3 ECC UDIMMs (double data rate 3 error correction code unbuffered dual in-line memory modules) or DDR3 ECC RDIMMs (double data rate 3 error correction code registered dual inline memory modules).

When installing or replacing memory modules, use the following guidelines:
• Use either DDR3 ECC UDIMMs or DDR3 ECC RDIMMs for your computer. Do not install both the UDIMMs and RDIMMs into the same computer.
• If your computer has only one CPU installed, be sure to install memory modules only in the memory slots adjacent to that CPU.
• If your computer has two CPUs installed, install equal numbers of memory modules in both sets of CPU DIMM slots for maximum performance. And the total amount of memory should be evenly balanced between the 2 banks. For example: If you are to install six 1 GB DIMMs in a dual-processor system, three of the 1 GB DIMMs should be installed in the CPU1 slots, and the other three should be installed in the CPU2 slots.
• Memory must always be installed in the blue sockets first, starting with the blue socket closest to each respective CPU. Install in the black sockets only after all blue sockets are occupied.

UDIMM 또는 RDIMM 둘 다 사용은 되나 동시에 두가지는 설치하지 말라고 되어있네요~

램용량 늘일려고 샀는데 하나를 더 사던가 일반 메모리를 사던가 해야겠습니다.
