Haswell DDR3L? Best RAID0 mSATA SSDs?

I was reading a bit about the Haswell memory controller and found a statement that it can only use the DDR3L memory. It is also listed as such on Intel ARK.
I intended to use two spare KITs of Corsair Vengeance RAM (8GB 1600MHz CL9 DDR3 1.5V) in the GT70 that is on its way to me but if i can only use DDR3L 1.25V-1.35V memory with Haswell than those are out...
Any official info if DDR3 1.5V can be used or would it cause damage? In this case what is the best DDR3L out there? I have been unable to find a 1600MHz CL9 DDR3L KIT...

Second im looking to upgrade the laptop to 3xmSATA RAID 0 (maby even 4xRAID0 if i can get it to work with 3xmSATA + 1xSATA) and am wondering which of the following 256GB/240GB mSATA SSDs youd pick (reliability is key and the faster the better)?
1) Plextor M5M,
2) Toshiba HG5d,
3) Crucial M4,
4) Crucial M500.
Theres also the Samsung PM841 or 830 but theyre hard to get here and more expensive and theres the also more expensive Sandforce driven Intel 525 and Mushkin Atlas but i dont fancy the unreliable Sandforce.

 

the problem about m500 is only 480GB and 960GB are the reliable spec

For those below 480GB are also known as rebranded of the M4 And V4

which is very slower than m4

 

i chose mine whilst all of the above are available for me to purchase, no reason for my choice though i just think it will be the best option

 

no, thats not a problem but a solution

and below the 480gb it still uses the same controller, so simply no

I wouldnt try putting a higher voltage ram in there, i would though simply buy anything that is available that is actually DDR3L

regarding the mSATAs, I would wait a bit for the m500 480gb to come out, its probably got all the necessary channels filled, or just go with the pm841 which is very hard to find anywhere

 

You are mistaken about the memory - Haswell supports both DDR3 (1.5v) and DDR3L (1.35v). Performance is based on timings and speed, not voltage. However, DDR3L will last longer and be easier on the battery in a laptop because of the lower voltage.

Kingston HyperX LoVo has a 16GB kit (2x8) and a 32GB kit (4x8) of DDR3L at 1600 CL9. That would be my memory recommendation. As for mSata, the fastest are the Plextor M5M and the Intel 525 series. The M5M is quite a bit cheaper than the Intel, though.

 

the ark disagrees with you, and I would trust the ark

 

No, you're just misreading the ARK. It says DDR3L - which actually means DDR3/L - either DDR3 or DDR3L. It accepts memory at 1.65v, 1.5v, or 1.35v.

See this image on Anandtech from Intel's IDF2013. It lists all 3 voltages.

 

that doesnt mean much, desktop support those, mobile doesnt

 

Karamazovmm, if you look closely to how voltage and current transfers energy you will notice the following: Higher voltage will break the components nearly instantaneously, where as high current determines the amount of heat generated from within the components

now look at the lower end: low current will get the components running but at a much slower speed(take a motor for example) and less heat will be generated, low voltage, however, will not break the components but instead determines whether of not the component will startup and keep running

this tells us that: if we insert a 1.5v rated ram into a 1.35v rated slot, fundamental electrical circuits will tell you that: 1.35v will get passed through the ram, thus this implies NO risk of frying any components but instead will be a question of whether the component will start up and keep running.... or not

thus I can say you can always try out standard voltage RAM, its just a matter of whether they will be fully powered or not, but you are risk free from trying anything

(take it as you need a certain amount of force to push a button, you can push the button at the rated force as many times as you like (current increase), but if you apply too much force on each push(voltage increase), the button will get shattered(PCB fried), if you push the button at lower force, however, you might not be able to actuate the button at all(less voltage)

 

Haswell fully supports 1.5v or 1.35v memory.

Otherwise there would be huge warnings that the majority of memory out there would not work correctly.

EDIT: This turns out to only be true for desktop chips, mobile chips have been forced to 1.35v by intel for power reasons.

 

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.

 

All RAM warnings I found so far.
Upgraders: 1.35V memory is required!
1.5v ram not compatible with haswell notebooks - BTOforums.com

It is funny to read about overheating LOL

 

hi there. i have the same question right now. i've bought normal ddr3 kingston ram but it didn't work properly on my msi gt60(i7 4700mq). did you find ram that fits you?

 

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.
