I am about to buy 16GB/8x2 of ram for my new Y400. (It came with 8GB/4x2.) But, I am wondering if it would take advantage of the lower power 1.35v RAM that is avaiolable now, or if it will end up running at 1.5v anyway. If the latter, I would just buy the less expensive 1.5v version. But, if it does support the lower voltage RAM, I'd prefer it for what I assume would be slightly better battery life.
Also, will the Y400 take advantage of lower CAS latency? If so, I'd spend more for RAM with a latency of 9 than ones with a latency of 11.
