hu hu... that's quite a lot to read. to give me a quick conclusion, can i say that even if i get a pair of 1600MHz 9-9-9-24, it won't gain much compared with my current sticks (1600, 11-11-F3; and 1333, CL9-9-9-24)? Also need to stress that I don't OC, and am not a gamer.
LOL
Well what it means is that CL always go higher as the speed increases from DDR to DDR2 to DDR3. It means that any gains in speed is effectively 'neutralized' as CL increases. For example, DD2-667 CL4 and DDR3-1333 CL8 produces the same amount of performance. Interesting right? Then why the fuss about going DDR3? The answer is bus speed increases. CPU buses are increasing year after year. DDR2 can only go so fast, it needs to go higher. (Read
DDR2 vs DDR3)
Therefore it is always a goal to keep CL as low as possible so that gains in memory speed is meaningful. Such is the case of Corsair Vengeance series and the likes, offering DDR3 1600MHz at CL9. JEDEC references DDR3 at CL11 if not mistaken so normal consumer RAM sticks will be there while performance brands will try to make chips operate at lower CL. Thats why the price is higher (lesser supply).
If you would look at the benchmarks, the difference ain't much. Especially now we're at Ivy Bridge (3rd generation Intel Core) where the memory controller is on the CPU package. Also we have GPU subsystem with its own independent GDDR5. Therefore it would be safe to assume that general performance aren't affected much.
Don't get me wrong. A performance RAM does provide increases in performance. The question is how much and whether that increase is where it matters most. 1-2fps increase? Few % increases in benchmark scores? What I do know performance RAM is good is where overclocking is concern.
Does anyone know if the Y480/580 can be overclocked and settings tweaked?

U need to check....
Mostly will only come with Atheros.....
Yeah its strange that there are so many Wi-Fi chips being qualified by Lenovo. So far we heard of Intel, Broadcom and Atheros. I know Broadcom Wi-Fi chips are desirable (beam forming

) but can't tell which chip model is being used.
