The HyperX H20 support Intel XMP (memory profiles) which makes basic overclocking a one step process. These modules have two memory profiles built into the design, one for 1866mhz and the other for 2000mhz. When these profiles are enabled they adjust memory timings as well as CPU clock multipler, bus speed (BCLK), UnCore Clock (QPI/DRAM) and DRAM Voltage.
Selecting 2000mhz proved no issue and we were able to push to 2130mhz with timings of 8-9-8-28 at reference voltage. Room ambient was 24c.
We tested the Kingston H20 modules in two states: passively cooled and then with watercooling. Our results show a 3c drop when idle and a 7c drop when overclocked … significant improvements.
We then decided to relax our timings a little to see how far we could push the H20 memory.
We managed to achieve 2350mhz after loosening the settings to 9-10-9. Let us check out some performance figures now.
