As far as I understand, the rules are quite easy: |
9 |
|
10 |
- Socket 940 -- Needs registered memory |
11 |
- Socket 754 -- Can use unbuffered memory |
12 |
- Socket 939 -- Can use unbuffered memory |
13 |
|
14 |
And I believe that at least Socket 754 CPU:s actually *requires* |
15 |
unbuffered memory, and can't use registered memory at all. I'm |
16 |
not entirely sure about that, though, and I don't know if Socket |
17 |
939 CPU:s can use registered memory. |
