    At times, we will need to accept the fact that more cost would mean more quality. I understand that this is not always true and there will be exceptions, but not in cases of sandforce based drives. If you are thinking I work for sandforce and trying to defend, you have mistaken. I am just trying to do justice to my experience of being associated with such quality products. Trust me they are reliable & I totally agree with Unusual1 that they are faster too.

    Sorry for bumping the thread but I was looking about some info of mobile Haswell supported RAM and came here.
    So at first i want to say that Unusual1 is totally wrong. There is no official info that mobile haswell supports regular voltage DDR3. All his words are totally speculations.
    I am aware that ARK Intel info is one of the weakest official prove so I went to a pdf specsheets here and found NOTHING about DDR3 but only about DDRL and DDR3L-RS. And all document is filled by these words and their specs (1.35V).
    @qweryuiop I heard about Macbooks which supported only DDR3L and their mobo fried after some time working with usual DDR3 1.5V.

    These doesn't mean that Haswell actually doesn't support 1.5V because I am the first one to believe that Intel on purpose didn't write all supported specs to reduce risks as 1600MHz RAM is definitely not the fastest standard BUT using wrong proofs is not what can help here.

    The lack of Huge Warning is the main thing to believe that 1.5V may be used.

    The Intel ARK is not known as a reliable information source.... It can be useful, but it is not the place to look if you want definitive answers about anything.

    Here's MSI answer for you.

    Intel mobile Haswell m / h CPU spec sheets state 1.35V only while desktop Haswell CPU specs also include DDR3 (1.5V)

    Best to stick with DDR3L IMO unless someone can prove otherwise.

    Out of curiosity is any one running 1.5V SO-DIMM in their Haswell laptop? If so what does HWinfo32 show as the DRAM voltage?

    Here to second this^. I've accidentally came across this: "Note: Haswell-based laptops use DDR3 Low Power (DDR3L, 1.35V) memory modules. Install only DDR3L memory if upgrading.". That's from ASUS G750 series brochure.

    I can confirm that 1.5v DDR3 sticks do NOT work with the new (Haswell) AW17s, I had a 2x8gb kit from my previous laptop (so confirmed working) which results in beeping when I try to boot the new 17 with it. (can't remember the number of beeps; whatever memory is) Rather annoying, as ram prices have tripled since I got these.

    I'll try overvolting (to simulate 1.5V DDR3) when a modded BIOS comes out, but until then I'm stuck at 8gb.

    There is DDR3L ram that is compatible with 1.5V but maybe the real questions are what will the mobile CPU supply and what supply does the notebook give the CPU for the RAM. Usually with notebooks RAM supply from the notebook regulator is fixed so is it high enough to support the CPU integrated regulator if it can supply 1.5V. Also DDR3 typically will use more power than DDR3L. So there's quite a few factors at play.
