1. was 1866Mhz. the fastest DDR3 memory ever manufactured?

2. what was the upper bound on the frequency DDR3 could be overclocked to on say sandybridge (and sandybridge-e) or broadwell (and broadwell-e)?

1. If I recall, 2800 MHz was top end.

2. I think it more depended on the motherboard, but this was long ago.

Thanks I got ivy bridge mixed up with broadwell. 2400Mhz. is still pretty good. Did it do 2400Mhz. with better latencies than that seen on later DDR4 architectures?

You can get CL10 2400MHz rated kits or 2133MHz CL9 (1,65V), and they should OC on top of that. If your CPU is able to do it... up to you to check. My Ivy-E does 2133MHz CL9 fine with 32GB of RAM.
It REALLY doesn't like 2400MHz speed though (lower write bandwidth than 2133MHz setting).
