Closer Look at Kingston KHX1866C9D3LK2/4GX (LoVo HyperX)
We took a pair of KHX1866C9D3LK2/4GX for our today’s test session. This is the today’s fastest model in the LoVo HyperX series, designed to work in DDR3-1866 mode. Besides high-speed memory modules like that, LoVo HyperX family also includes DDR3-1800, DDR3-1600 and DDR3-1333. In other words, this is where the manufacturer decided to try and combine two seemingly opposite things: overclocker speeds and energy-efficiency.
LoVo HyperX modules are shipped in a pretty common package: two memory DIMMs with aluminum heat-spreaders sealed in Kingston’s traditional plastic box:
You can easily tell the low-voltage modules from the regular ones by the color of their heat-spreaders: they are green instead of light-blue, which should naturally bring up an eco-friendly associations. Other than that they look just like the regular HyperX memory modules, which we are already well familiar with.
The heat-spreaders are decorated with the company logo, HyperX brand logo and DDR3 sign. “LoVo” name is only mentioned on the sticker together with the full marking. Besides logos, the sticker also bears some technical info, product part number, its operational voltage setting and the fact that it consists of two modules.
The complete Kingston KHX1866C9D3LK2/4GX technical specification looks as follows:
- Dual-channel kit includes two memory modules, 2 GB each;
- Nominal frequency: 1866 MHz;
- Timings: 9-9-9-27-1T;
- Voltage: 1.35 V.
Besides that, the manufacturer claims that KHX1866C9D3LK2/4GX kit can easily work at 1600 MHz frequency with even lower voltage setting of 1.25 and 9-9-9-27 timings.
These two modes are recorded in the XMP profiles supported by all LoVo memory kits.
Although LoVo memory boasts pretty exotic specifications, its internal design is quite common. Aluminum heat-spreaders are pressed against the memory chips with two steel locking clips with a traditional thermal band inserted in-between.
As for the chips, they used the legendary Elpida “Hyper” ones that are currently used in most overclocker products.
However, in most cases the memory makers would squeeze some record-breaking frequencies out of these chips, while Kingston engineers focused their efforts on a different aspect and picked the chips that could support low voltage settings for their LoVo family of products.
