Overclocking
Overclocking is never guaranteed so presented results may vary from results on the other memory kits. I’m not recommending overclocking if you don’t know what are you doing. Too high voltage may damage hardware and it won’t be covered by warranty.
While writing this review I’ve received new six core i7 4930k CPU and MSI motherboard based on the X79 chipset. Since we have four 8GB memory modules then I will also add couple of results in quad channel on this new high end setup.
Maximum stable overclocking result:
For both Z87 and X79 platforms maximum stable overclocking result without raising voltage was DDR3-2666 11-13-13-35 1.65V. It’s maybe not so impressive till you realize it’s working at all 32GB RAM !! What is also impressive, no matter if you use two or four memory sticks , it can work at the same settings with the same stability.
Below is full timing list of the stable settings achieved using Gigabyte Z87X-OC motherboard.
Overclocking results on the Z87 and X79 chipsets
X79 platform was harder to stabilize as it’s using quad channel memory controller. Maximum clock achieved using memory voltage of 1.75V was 1365MHz ( DDR3-2730 ) 11-13-13-35.
Loosening timings or raising voltage didn’t help so I assume it’s motherboard or memory controller limit.
Z87 testing rig could make higher clock reaching pretty stable 1400MHz ( DDR3-2800 ) 12-14-14-36 ~1.75V.
Overclockers will be also interested how low I could set timings at higher clocks. In this case tightest timings that could pass most benchmarks were 11-14-13-36 at DDR3-2800 mark. Used voltage was also near 1.75V.
Maximum overclocking result:
Highest overclocking result was possible on the latest and improved Intel Haswell memory controller. All 32GB could run in simple tests at 1466MHz ( DDR3-2933 ) what is really good result for 32GB memory.
