Hello. I have laptop with motherboard Clevo W670SFQ (Intel HM86), DRAM is 2x8GB DDR3L. So, in the BIOS I have option to change mode (DDR3 or DDR3L). But it doesn`t work, with activated DDR3 value real voltage is 1.35V, because my DRAM DDR3L, I think. How to force DDR3 value (1.5V) with DDR3L DRAM?

DDR3l is compatible with DDR3, maybe the main board is not compatible with memory.

Ivy Bridge and up support DDR3L, so I don't know what you're trying to achieve?

Sorry, didn`t said about main problem. I want to overclock DRAM, with 1.35V it can`t pass through 1600Mhz. With higher voltage it should work 1866/2133 Mhz, maybe more.
