And that's with usage of FX4330(4-core, 8M, 4GHz)
CN-Heavy consumes 4M of cache, better use two threads with multi-hash 1

Agree with your logic but it does less hashes that way.
So, I've got some observes:
01 + 31 = 114   01 + 32 = 128   02 + 31 = 128
01 + 21 = 114   02 + 21 = 128
01 + 11 = 92   02 + 11 = 85   01 + 12 = 85
11 + 21 = 114   12 + 21 = 128   11 + 22 = 128
21 + 31 = 92   22 + 31 = 85

The conclusion may be that miner uses not the only L3 cache which is one for all cores but it uses L2 caches which are numbered to core modules on the exact cpu.
FX4330 has 2 modules by 2 cores with 2MB L2 each. And the sum of L2 and L3 is exact 12MB.
Unfortunately I've already sold all of my 8300 and 6300 FXes. Would be nice to test them again.
That can be used to tune any CPU.
