While PC3-15000 might be a bit of a weird number with PC3-16000 being a bit more common, the particular kit comes in at 1866MHz DDR. The 4GB kit runs in a 9-9-9-27 setup at 1.65v. Ultimately this isn't anything too out of the ordinary. As for achieving the speeds, there wasn't a single issue; we set the BCLK to where it needed to be and lined up the modules at 1866MHz DDR. By the time we ended up in Windows, though, they had jumped slightly to 1875MHz DDR.
As for going further, we fortunately had a bit of luck. While we thought we would be optimistic and simply aimed for 2000MHz, we found ourselves shot down pretty fast. With that said, though, a bit of timings adjustment and no extra voltage saw the modules achieve a clock of 1935MHz DDR or a 69MHz DDR overclock from the stock speeds. It's not a massive overclock, but a free 5% isn't something to complain about.
Important Editor Note: Our maximum overclocking result is the best result we managed in our limited time of testing the memory. Due to time constraints we weren't able to tweak the motherboard to the absolute maximum and find the highest possible FSB, as this could take days to find properly. We do however spend at least a few hours overclocking every motherboard to try and find the highest possible overclock in that time frame. You may or may not be able to overclock higher if you spend more time tweaking, or as new BIOS updates are released. "Burn-in" time might also come into play if you believe in that.
