Features & Specifications

Since the advent of the Intel LGA1366 socket, the memory controller for Intel chips has been directly connected to the processor, allowing a huge bandwidth leap in triple-channel setups. The LGA1156 socket chips, however, all run in dual-channel DDR3 mode though, not tri-channel. While we know this won’t result in such eye-watering performance numbers, the 1156 platform has brought "affordability" to Intel’s mainstream performance platform, at least at the lower end of the product spectrum, and certainly in comparison to the 1366 platform.

So while the LGA1366 motherboards take tri-channel memory modules in a 3 or 6-slot configuration, the LGA1156 socket uses 2 and 4-slot dual channel configurations. Most people are probably very familiar with this setup, though the primary difference now is that DDR3 is the new standard, not DDR2.

There is a caution, however, with the P55-capable DDR3 modules: you must have DDR3 sticks that can run at 1.65V or less. Do not be confused with other DDR3 products that run at 1.9V or higher, for example. Be sure to read the specs very carefully before you order to ensure you get the right ones! This is because Intel has set a maximum voltage limit of 1.65 volts on the memory modules, due to the Integrated Memory Controller which is located on-die in the CPU itself. While there are exceptions in exceeding the 1.65 voltage limit, if you go higher then you run the risk of damaging your lovely i7 or i5 CPU. Pushing beyond that limit can be done somewhat safely under special circumstances, but we do not recommend that for novices, so be forewarned.

OCZ’s OCZ3X1600LV4GK features the following (from OCZ):

OCZ low-voltage DDR3 kits are designed specifically for the Intel® P55 Chipset and subsequent Intel® Core™ i7, i5, and i3 (Socket 1156) processors. Configured for dual channel mode, these ultra-compatible 4GB kits ensure optimal performance with an ideal combination of low power requirements at 1600MHz.

Developed for cost-conscious enthusiasts and gamers, these new OCZ modules were engineered with the same affordability and performance standards as the new Lynnfield platform. By using sophisticated IC screening methods and qualifying on a variety of motherboards, OCZ low-voltage kits are the perfect complement for the P55 Chipset and choice CPU to deliver the maximum stability. Together, P55 and OCZ memory are the premium option for the midrange desktops.

Designed to significantly increase performance levels of the entire platform, these modules feature Intel Extreme Memory Profiles (XMP), a proprietary extension of SPD (Serial Presence Detect) settings that act as an integrated “plug and play” overclocking tool. The new Extreme Memory Profile options on the new OCZ DDR3 modules allow the end user to select ultimate performance through a framework of predefined and validated optimizations of individual settings without the hassle of manually adjusting each parameter, so the timings, voltage, and speed boot automatically for maximum performance.

Here are the specifications of the OCZ XMP Edition 4GB DDR3-1600 Low Voltage Dual Channel:

  • Model: OCZ3X1600LV4GK
  • Module Size: 4GB kit (2x2048MB)
  • Package: 240-pin DIMM
  • DDR3-1600
    (PC3-12800)

  • 8-8-8 Timings
  • 1.65V
  • 256MB x 64
  • Intel Branded XTC Heatspreader
  • XMP-Ready
  • Lifetime Warranty

With Extreme Memory Profiles (XMP), these OCZ modules already have the pre-configured voltages, timings, and speed settings programmed in, so you can be confident that you have a fully-verified level of performance. This means that you don’t need to worry about endlessly tweaking the various settings to get the most out of your modules; just go into your BIOS, select XMP and then reboot.

Let’s take a closer look at these OCZ XMP Edition modules.
