L2 Cache Question

[Taliseian]

According to CPUz and SiW, my proc has an L2 Cache of 4 (cores) x 256KBytes.

For tweaking purposes, is that a 256k cache or a 1mg cache?

Thanks in advance....

That would be 1MB of L2 cache. Hope this helps.

(This is if it's a 4 core CPU)

What tweaking purposes? Whatever it is, I can assure you those "tweaks" are meaning less.

Something is wrong with this picture.

And the tweak is meaning less.

On a Core i7 920, the 8 MB cache is L3. 1 MB of L2 is divided up among the 4 cores. However it should only be calculated as 256 KB not as 1 MB. There is only 256 KB of L2 not 1 MB, if (and only if) the L2 was shared among the cores then you could.
