I have y560 (i5 430, 4gb(Elpida 1333mhz), hd5730) Lately I was curious and I checked my laptop performance. I run game and in backgrond CPU-Z/Everest. CPU OCed to 2527MHz ati also jumped with clocks all fine. Then I swith to Memory bookmark.
Here problem starts. Laptop FSBRAM is 4:16 and ram works max with DRAM532MHz (1066) should with 667MHz (1333). So I checked ram labels and it is PC3-10600. I ran everest to check. Also shows it is 1333 ram. When I play any game/do anything ram never increase to 667mhz. Always stays at 532MHz (1066). Obvious is that I want it works with 1333MHz not with 1066. Why max ram speed reaches 1066 not 1333 ? How I can change this?
Also when I change power modes HighPerf/Balanced/PowerSavr only cpu multiplers change, FSB always stays the same 133mhz(never oc)

Are both of your RAM modules the same ?
As the computer support dual channel if there is one module slower it will slow the other one.

Ok I found the answer,
The Intel Core i5-430m support DDR3 800 and 1066 not 1333. Your benchmark shows you the speed 1333 because the RAM is able to reach this speed but it limited by the motherboard.

So why manufacturer sells such a stuff? How became happend I bought laptop i5 with 1333 ram? Laptop spec says it is 1333 and can't go to 1333? Why anyone think to put 1333 in it? I feel cheated. Next minus for Lenovo. Again misinformed and tricked.
I am disappointed ;(
Thank you Vince69 for help.
