Overclocking and Conclusion
Memory Overclock Speed Testing
The memory overclock speed testing was conducted with all board settings at stock speeds with the exception of the memory speeds. System stability was validated over an 8 hour period with the AIDA64 stability test in conjunction with EVGA's OC Scanner X graphical benchmark set to a 1280×1024 resolution and 8x MSAA in stress test mode.
Board voltage and memory timing settings were configured as follows:
- DRAM Voltage – 1.375V
- CAS Latency – 16
- tRCD – 18
- tRP – 18
- tRAS – 40
- Command Rate (tCMD) – 2T
Using the Gigabyte Z170X-Gaming G1 motherboard, the Corsair Vengeance LPX DDR4-3200 modules reached an impressive 3466MHz speed with a memory voltage of 1.375V and 16-18-18-40-2T timings. However, the modules would not run at any higher speeds no matter how much more the memory voltage setting was increased.
The Vengeance LPX DDR4-3200 modules perform well at stock 2133MHz and at their rated 3200MHz speeds when used in conjunction with the new Intel Z170-based systems. Running the modules at their rated 3200MHz speeds was as simple as setting the memory ratio, timings, and voltage settings to the specified values. We did not even need to use the XMP settings to get the modules running at those speeds. While the Corsair Dominator modules outperform the LPX modules at their rated settings, the LPX modules are a much better value because of the price differential between the modules. Further, the overclocking potential seen with these modules make them a steal.
As of September 01, the Corsair Vengeance LPS DDR4-3400 16GB memory kit was available at Amazon.com for $269.37. The kit was also available from Newegg.com for $174.99 and from Corsair.com for $224.99.
Corsair is well known for their performance lines of memory, continuing this trend withe their Vengeance LPX DDR4 line of modules. The Vengeance LPX DDR4-3200 memory kit is a prime example with performance rivaling that of other kits at both stock and overclocked speed settings. It even puts up a good fight against the vastly more expensive Dominator Platinum DDR4-3400 kit, but wins out because of the Vengeance kit's vastly lesser price. The modules are well constructed with a redesigned aluminum heat spreader for optimized passive cooling. For operating at its rated 1.35V, Corsair included 2 sets of their Vengeance Airflow coolers. The coolers add a bit of height to the modules, but cool the modules well and offer a switchable colored base plate for matching almost any system aesthetic. Getting the modules to run at their rated 3200MHz speed was as simple as setting the BIOS memory ratio, timings, and voltage to the Corsair specifications. There is no reason not to pair these modules with your favorite Intel X99 or Intel Z170-based system.
