DDR3 2800 at same CL and other parameters, 1T and 2T performance are similar.
Most benchmark software above has better performance in 1T. However, 2T set up has better stability.
As DDR3 2400 and 2800 difference, DDR3 high clock does have better bandwidth.
I would like to mention AIRFLOW cooler temperature performance at DDR3 2800 2T setup.
If without AIRFLOW, the max temperature is around 47.5, otherwise it's about 37.6.
The temperature drops 9.9 degree C. It's helpful for stability for sure.
Intel new structure always advantages DDR3. Either pull higher clock or performance improved as same bandwidth.
Last generation, Sandy Bridge, max is DDR3 2133. Ivy Bridge max is DDR3 2800.
Regarding to DDR3 clock improvement, if CPU clock can pull higher than 100MHz, the clock will be higher.
These 2 generations structure sync CPU clock with PCI-E clock. If you pull CPU clock too high, the system stability is a question.
So this review only set CPU clock at 100MHz.
CORSAIR most high end DDR3 product line, Dominator Platinum, has several clocks.
The official site shows 5 models from DDR3 1600 to DDR3 2800. Higher clock is higher price.
DDR3 is no more competition for clock performance and capacity.
As RamDisk software becomes more popular, more DDR3 capacity provides richer and more convenient applications. Especially, the incredible bandwidth leverages the performance.
This review, Dominator Platinum DDR3 2800 CL11, performance is excellent.
I hope it will have 8GX4 version soon. It will show us another milestone of DDR3 performance.
DDR3 can be higher or not? 8G price can be more parity? I think these are what end users care about.
Hopefully, after 2nd June, Intel new Haswell structure will fly over DDR3 3000.
