So i've been looking at a few different memory modules for a new mITX rig i plan on building in the new year. Its down to either...

Corsair Vengeance 8gb 1600Mhz 9-9-9-24
http://www.overclockers.co.uk/showproduct.php?prodid=MY-307-CS&groupid=701&catid=8&subcat=1390

or Kingston Hyper X Fury - 1866Mhz 10-10-10-28
http://www.overclockers.co.uk/showproduct.php?prodid=MY-172-KS&groupid=701&catid=8

As i need something to thats relatively low profile to ensure good airflow in the teeny tiny FT03 mini case i want to build in.

However, i have just noticed the corsairs are also available in a low voltage module, acheiving the same cas timings/clock frequency on 1.35V. I was wondering what main advantages/disadvantages of this would be.

There are obviously some OCing advantages, but i'm no extreme OCer. I was planning on getting 4690k and probably software OCing it (because i'm lazy more than anything else) to 4.4Ghz tops and thats about me done. I'm not above changing the odd bios setting, but if it cant be done with 20-30 minutes and a youtube guide i'm not doing it... so unless RAM can be OC'd relatively quickly/easily/safely? i probably wouldn't get anything extra here.

So if i don't want to spend hours tinkering in my bios is there any real advantage or disadvantage?

surely if the cas timings and frequencies are identical, so long as the motherboard supports it i may as well get the low voltage modules and save a bit on my power bill and stress my PSU less?
Or is there some glaring disadvantage that i'm overlooking?

and if anyone has any opinions on my ram choices feel free to throw them in there too, there for an i5, geforce 970 gaming rig that needs to run the odd bit of mat lab and serve for the usual word doc/internet trawling...

Thanks as allways.

Most of the low voltage sets that cam e out were sort of testing the waters for DDR4, as long as the mobo supports it, it's fine, the Snipers mentionedhad some low voltage models out that might be available from 1.25 to 1.35, they are also perfectly safe to run at at 1.5, so should be good either way

so thats pretty much it, if the mobo's compatible then meh, why the hell not? i posted the details for the wrong corsair module anyway ^^ the ones i have seen are CORSAIR Vengeance LP 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866 Desktop Memory Model. There CL9's, similar to the GSkills but they don't look like they belong in a toy box.... (just my opinion)

Im pretty sure there not laptop ram, there just low voltage.
found a review here

i was just curious as to any other pros/cons.
The loss in frequency is pretty negligible, especially with the better cas timings.

It's not so much a case of MOBO clearance as it is airflow, its one of silverstones vertical case orientations, it uses 1 large input fan at the bottom pushes air through the case and out of the top. the motherboard is mounted vertically against the back of the case, Big ram modules leave a bit of an airflow choke between the ram and the psu which is mounted at the top. Id rather just get low profile and keep airflow good in such a small case, since ram heatsinks are 99% show anyway.

i think i'm leaning towards the kingston furys anyway, linus tech tips did a review and said there very conservatively clocked/ timed, meaning that with a small amount of tinkering they can be clocked to 2133 no worries with reasonable cas timings. Apparently some reviewers were getting them up to 2600+mHz! Considering i'm planning on a very conservative processor clock i shouldn't have to much problem upping the ram frequency a bit.

i have been looking into it and its not going to be too time consuming/difficult. especially seeing as i'm going to let asus ai suite do the majority of the work in terms finding out max stable cpu clocks etc.

that and i was always a fan of the old blues. However its good to know i have the option of getting the 1.35V and running them at 1.5V so thanks. makes me wonder just how different they are to 1.5V modules....
