Maximum voltage for Sniper 1.25v

[Bobby]

What is the maximum safe voltage you can apply to Sniper F3-12800CL9T-12GBSR2 Modules? (1.25v to ?)
Can you push this from 1600 to 1800?
Not much information on this new low voltage ram. I need to know it's limits.

ASUS Rampage III Formula
Intel i7 970 3.2g @ 4.1g CPU ( idle temps 28/32c, Prime95 Torture 59/64c @ 4 hours )
Ulta 750w PS
H 100 CPU cooler
Cool Master 932 HAF with 8 case fans
2x WD 500 Black Caviar Raid0
1 WD 2T Black Caviar (storage)
2X G.Skill F3-12800CL9-GBNQ

Will I be able to reach this with the Sniper 1.25v Modules?

Thanks-Bobby

For 1800 I'd guess 1.3 to 1.325 or so, I'd keep them to 1.4 or lower
