(I dont know the exact core count of both processors...) |

But may be additional cores of the Phenom II (x6?) will result |
25 |
in more mem preallocated by the BIOS (may be without reason). |
26 |
|

On my system (8GB,Phenom II X6 1090T, ASUS Crosshair IV Formula) |
28 |
there are 8184216 kB in total. |

So even the 7738 Mb seems to be lesser than possible. |

Only a shot into the dark... |
