same DDR3L in x58 and z170

[p377y7h33f]

i cannot find any confirmation that this would work, though i did get a vague confirmation by calling ASUS. so here's what i'm trying to do.

i currently have an LGA1366 x58 Asus mobo - Rampage III Formula. the 6GB of very nice Corsair DDR3 at 1.65v is becoming not enough finally. i decided against going with 6 sticks to get to 12GB, as i'm already OC'ed(i7-950 @ 4.0GHz) and would rather not have to jack up that QPI voltage to run 6 sticks at 1600MHz.

the plan is to eventually get a z170 with DDR3L support for that 6700k... eventually. all i want to do at the moment is purchase a 4GBx4 DDR3L kit and use 3 of the 4 modules in the x58 for the time being.

will this work, and is it a good idea for my wallet?

EDIT: unless i go with this Vengeance 2133 8GBx4 kit. Corsair says it's backward compatible with 3RD GEN cpu's, and mine is a first.

let me rephrase this question: would ANY DDR3L memory work with a 1st gen Bloomfield?

EDIT: i found 1 G.Skill 1600 2GB module that is rated for 1.35v, but that's tiny and slow for a Skylake.

All good brand DDR3L is dual voltage, I think. 1.35/1.5V

spoke to a guy at Mushkin, and he said it should be fine. Corsair just wants to be on the safe side and only mentions 3rd, 4th, and 5th gen for backward compatibility. guess i will be the lab rat and give it a try.

hopefully that 8GB x 4 2133 Vengeance kit will OC well with a Skylake.

EDIT: the more i'm finding out about this the more stupid it seems to go with a DDR3 Z170. the ONLY motherboard to even consider for this is an Asus Z170 P D3, which is on the low end and doesn't even do SLI. so now i'm torn between doing a 4790k build on a dead end Z97 platform so i can reuse the DDR3(which i havent bought yet) and have SLI, or go for a proper Z170 with DDR4. in the mean time i still need to get an extra 6GB of DDR3 into this x58, and six sticks doesn't seem like such a bad idea after all. got a local guy selling identical Corsair XMS3-1600 with 7-7-7-20 timings for $25 per 3 sticks. fingers crossed 1.4v QPI/VTT will be enough to run them all together.

kept researching this and making calls, as the whole DDR3L is extremely confusing.

while Intel says anything over 1.35v in a DDR3 slot is a big NO for Skylake, Asus, Gigabyte, and Asrock all list 1.5v AND 1.65v DDR3 on their memory QVL for the DDR3 Z170 boards. a few random posts here and there all state they're fine at 1.65v. one guy on guru3D even started a poll encouraging people to predict how long his 6700k will last with that +0.3v to the memory.

whatever, i just picked up a 12GB set of 3x4GB Mushkin Redlines 1866 DDR3 rated for 1.5v and will run it at 2000 in my x58. by the time i upgrade Cannonlake will be out and the 200 chipset will probably still support DDR3, hopefully with SLI.
