T3600 with SAMSUNG (CISCO) PC3L-12800L 64GB (32GB x 2)
After some research I bought the above memory for a good price, more or less expecting (accepting) it wouldn't work. 12800L instead of 12800R, ie 1.35v instead of 1.5v, and not the recommended configuration of 16GB x 4.
However, so far so good! Latency is showing CL9 instead of the original CL11 which I presume is down to the higher voltage.
I guess time will tell if it's viable long term. The memory has heat spreaders and is warmer, but not hot. Unfortunately I don't have the plastic ram cooling 'ducts'. Any thoughts?
