Ultra low profile 1.35v 30nm DDR3 capable of 2400MHz. Perfect for SFF builds.

Low profile 1600s are the only confirmed 30nm. I have the 1333 kit which was initially advertised as 30nm on amazon but is now advertised (correctly) as 40nm.

Either way the kit seems pretty good actually. 10-10-10-28-1T booted first time @ 2133mhz / 1.5v. Cant lower timings at all though. Im actually testing it at 1.45v now and it looks ok.

LagunaX - low profile 1.35v 1600mhz is the only guaranteed 30nm stick the same as the results you see in this thread. While the low profile 1.5v 1333mhz kit seems good as well mine dont seem capable of cas 9 like the 1600mhz kits seem to be able to do. I really wouldnt upgrade though if I were you - theres no point. You will see zero difference in use. At best youll get a couple hundred mb/s in everest and maybe a second 32m superpi.
