TDP & TDC limits are power & current limits when Turbo Boost should be decreasing. The calculation is like this:-
Code:
For example, TDP limit = 178h = 376 (decimal)
The value is in 1/8ths:-
376 / 8 = 47W
x-Core Ratio Limit where x is a number of active core(s). So, the number set in these fields are the max multiplier.
Code:
For example, 2-cores active:-
2-Core Ratio Limit = 17h = 23 (decimal)
So, the max multiplier when 2-cores active are [b]x23[/b].
So, to overclock, need to increased these numbers.
Ok now i understand.
For example if i want a multplier of 28 i set the core 1 and 2 at 22h? (22h=28)
And the core 3-4?
The TDC limit, if i want 70w, how mutch is the value?
The last question, it's possible in this bios increase the Serial Bus? The Dell M18x have this possibility to increase from 133mhz to 140/144mhz with the same 920xm; but in the bios that you have mod i don't have see this.
If i increase the fsb, i set the multpier more slow and the 920xm have minor stress.
28x133=3,7 ------ hard stress for cpu because the multplier is too high
27x140=3,78-3,8 ----- more stable cpu for a smaller multplier
27x144=3,9 ------ setting of Dell M18x. More stable and high performance (Function not prensent in Poenix Bios)
Thanks for your respons and sorry for my english.
