Just remember that the i7 9xx series changes your memory frequency to 1066 at stock.
So what is the point of stating the motherboard supports up to 1600mhz memory if the CPU limits this to 1066 (overclocking)? The memory specs for standard and extreme 9xx series are the same, where does the faster "quick path interconnect" (QPI) bandwidth come into play?
Ignoring the overclocking issues, then it seems what I'm looking for is a low latency timing while running at 1066mhz. One of the "value ram" memory components from Kingston is speced to run at 7-7-7-?? at 1066mhz at 1.5volts. The 4th paramter isn't specified. The 1333mhz hyper x memory is tested at 7-7-7-20 at 1333mhz at 1.65 volts, but will report 9-9-9-?? for 1.5 v.
Assuming I'm not overclocking the cpu, then it's stuck at 1066mhz, and the memory isn't going to be any faster unles it can run with a lower latency rate, like 6-6-6-??, but this isn't covered in any of Kingston datasheets for their memories.
