Hi, I have a Toshiba A660-PSAW3E(PSAW3E-02D00JGR) Laptop with: Processor: Intel i7 720QM RAM: 4GB DDR3-1066(2 x Samsung M471B5673FH0-CF8) HDD: Toshiba 640GB Graphic: nVIDIA GeForce GT330M Non-shared 1024MB BIOS Phoenix V2.0 (last update 26.05.2011) Windows 7 Home Premium 64Bit Yesterday I've got 2 x 4GB Samsung M471B5273CH0-CH9 RAM modules that are supposed to run under 9-9-9-25 @667MHz unfortunately they are running at 8-8-8-22 @609MHz. I've checked the laptop for compatibility with Aida64 before I purchased the new RAMs and the result was that the laptop can run 1333MHz(667MHz) modules, but I'm not getting full speed at the moment and the seller told me that his product is supposed to run at 9-9-9 and he wondered as I told him that it's running slower. How can I know if the laptop RAM speed is somehow limited by the BIOS or the new RAM modules are slower than supposed? Thanks in advance.... Ararain
