Since the modules are rated at 1600MHz 9-9-9-27 what better place to start then to see if the loose timings can be improved upon. To start with I lowered the Cas Latency, TRTP and TRD to 8 and the TRAS to 24 all while running the default 1.65 volts. Expecting a black screen I was surprised that the modules booted and then tested fine at 8-8-8-24. Next I started bumping the memory speed up by increasing the bclock a few MHz at a time and rebooting. Then thing is the modules kept scaling with the 8-8-8 subtimings until I reached 1884MHz. So far 284MHz worth of extra clock speed. At this level I was able to benchmark game and run stability tests at will. Any higher though required the Cas Latency to move to 9. Voltage did not help and above 1.68 I would get errors so the max voltage used was 1.67 volts. Moving on up from 1884 I finally reached 1976MHz with the timings at 9-9-8-24 with the memory voltage at 1.66 volts QPI volts at +220 and the CPU at 1.28 volts. 376MHz (187MHz actual) worth of increase for a set of memory that costs just 131 bucks is nothing to sneeze at. Unfortunately 2000MHz just was not to be for me on this set. So close yet so far.
