    Hi,
    I'm in the business of getting new RAM for my M17xR3 and I wonder how my 2630QM Sandy Bridge board will handle a pair of 1600 MHz 8 GB sticks running at 1.35 V. I have read that I will need to change the XMP profile to 2 in order to take advantage of the 1600 MHz, but how will my board deal with the fact that the sticks are 1.35 V?

    Currently, I have the stock 2 x 4 GB modules and when I check the overclocking options in my bios, the RAM voltage option ranges from 1.5 - 1.65 V. Is this simply because the bios recognizes that these are the values which my current RAM support and thus they will change when I install 1.35 V RAM or will I have to run the 1.35 V sticks at minimum 1.5 V? If the case is the latter, would I fry my 1.35 V sticks? Or would they become automatically overclocked and get tighter timings with a higher voltage? Or both? or neither? I'm a bit lost :p

    My question was answered over at SuperUser laptop - 1.35 V RAM in a 1.5 V system - Will it fry or overclock? - Super User.

    I will order it and report back if I run in to any issues.

    So I just got my new 1.35 RAM sticks ( Newegg.ca - Crucial 16GB (2 x 8G) 204-Pin DDR3 SO-DIMM DDR3 1600 (PC3 12800) Laptop Memory Model CT2KIT102464BF160B). Upon first boot, without modifying anything in BIOS, this is what CPU Z shows:

    2013-03-13 11_54_28-CPU-Z.jpg 2013-03-13 11_54_01-CPU-Z.jpg

    So I guess this means that they are actually running at 1.28 V and 1600 MHz without me setting the XMP profile to 2 (I tried that at the second boot, but just got 2 loud beeps and then the BIOS was set back to using the default profile). A bit confused about the 1.28 V as well since they are rated at 1.35 V and I read in another post here that my mobo should not even detect this and just push through 1.5 V. Not sure if this means that they came with some sort of plug and play XMP profile even though this wasn't listed anywhere.

    But whatever, everything seems to work fine so I'm happy! If I'm misinterpreting anything here and about to blow up my laptop, please let me know.
