Kingston HyperX PC3-15000 (1866MHz) LoVo 4GB Kit

Overclocking

While rated at PC3-15000 or 1866MHz DDR, there are actually two XMP profiles when you dive into the BIOS. The LoVo series as we mentioned stands for Low Voltage. While most of the memory we look at these days is performance stuff carrying with it a 1.65v rating, at 1600MHz 9-9-9-24-1T a small 1.25v is only needed to run the memory. At these settings we didn't have any issues running the memory.

The next profile is the standard 1866MHz 9-9-9-27-1T one. While not as low, this still only requires 1.35v to get up and running. We again didn't have any issue achieving this speed.

Since we didn't know if these modules could run high voltage or not, we decided to move the voltage just to 1.55v to see if we could get some head room out of the modules at the default 9-9-9-27-1T setup. We didn't run into any problems and settled on quite a nice 2035MHz DDR. Really, this is a nice jump from 1866MHz DDR at 1.55v while still keeping the 9-9-9-27-1T setup.

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.
