Actually, they will run, they just won't run at 1.35v. I learned the hard way. The first Corsair Vengeance low voltage DDR3L 1600 SDRAM I put in wouldn't run below 1.8v. Although I now have 1.35 v Mushkin installed, but it's running at 1.5 v.
I appreciate your posting this. I couldn't figure out why I couldn't get it to work at 1.35v. I have an i5-3570K in an Intel DH77KC motherboard, and the motherboard specs say:"The board has four DIMM sockets and supports the following memory features:
1.5V DDR3 SDRAM DIMMs with gold plated contacts, with the option to raise the voltage to support higher performance DDR3 SDRAM DIMMs.
1.35V Low Voltage DDR3 DIMMs (JEDEC specification)"
It hadn't even occurred to me that the cpu might not handle DDR3L sdram. You would think Intel might at least put an asterisk on their own motherboard specs indicating "not supported with 3rd generation core processors". They make a point of telling you in the specs that " Third-generation Intel® Core processors are the only processor family that supports DDR3 1600 MHz DIMMs" but don't say a word about NOT supporting low voltage ram. So you need a 3rd gen chip to get 1600, but need a 2nd gen chip to use 1.35v. How assinine is that?
Guess I'll order some regular 1.5v 1600 SDRAM when I find it on sale and save the 1.35v for some future use.
Just to clarify the data sheet at the place you cited specifies that the DDR3L will run, but only at 1.5 v. It says:
"System Memory Interface I/O Voltage of 1.5 V
DDR3 and DDR3L DIMMs/DRAMs running at 1.5 V
No support for DDR3L DIMMs/DRAMS running at 1.35 V
Support memory configurations that mix DDR3 DIMMs/DRAMs with DDR3L DIMMs/DRAMs running at 1.5V"Edited by Zon2020 - 6/28/12 at 9:12am
