New Memory Tweaker for Intel Chipsets

[GamerBR]

Great software. I've own a laptop for more than a year that the limiting factor for overclock was obviously the memory, and only today I had this idea to search if there was a software able to change timings on windows.

While I'm able to change tRCD, tRP and tRAS I can't change CL, I can choose some other number, but it just ignores and return to the default, I don't even have to apply the settings for that to happen. Does that mean that only CL is locked?

Edit: Nevermind, tried SPDTool but apparently my memory doesn't support CAS over 6, at least the only options there are 4, 5 and 6.
