  • Good Performance At Stock SPD/XMP Profiles
  • XMP Support


  • Not Really Designed For Overclocking
  • Performance Not Guaranteed With More Than Two Modules


  • Matched 4GB PC3-12800 DDR3 DIMM Modules for Dual Channel Performance
  • 9-9-9-28 Latency @ 800MHz (9-9-9-25 XMP)
  • 1.5v Operating Voltage
  • Red Aluminum Heat Spreaders
  • Lifetime Warranty

Guide Review - G.SKILL Ripjaws PC3-12800 8GB (2x4GB) DDR3 Memory Kit

Jun 9 2011 - G.SKILL's Ripjaw series of memory modules are designed for performance minded computer users. The PC3-12800 DDR3 memory kit that I'm looking at today is a modest performance platform for those looking at some fast memory without having to do much adjustment within their desktop PC. The modules themselves offer a standard aluminum heatspeader stylized to look like a set of teeth but they aren't overly larger to prevent the use of a CPU heatsink that would also cover the memory module area of a motherboard. Since they do stand slightly higher than a typical heatspreader, it is still best to check.

In testing with AIDA64 on an Intel Z68 chipset with a Core i5-2500K processor with the standard SPD settings, memory bandwidth was able to achieve an impressive 18,566MB/s with reads and 18,810MB/s for writes. The latency was able to achieve a very respectable 42.2ms response times. This charts a bit higher than standard PC3-12800 DDR3 memory and should provide good overall performance for those looking at solid performance without the need to overclock.

The G.SKILL Ripjaws PC3-12800 DDR3 memory modules are not really designed for overclocking beyond the JDEC DDR3 1600MHz speed ratings. It is possible to achieve some modest speed increases with the modules if the voltage to the memory modules is increased beyond the 1.5v standard and adjusting the carious latencies higher. Those looking to do serious overclocking of the memory modules will really want to look at higher speed rated modules which do typically add to the cost.

In addition to supporting the standard JDEC DDR3 1600MHz via the SPD, the Ripjaw PC3-12800 modules also support the XMP profile. This is an important feature for anyone using the Intel P67 or Z68 chipset computers and overclocking. This helps increase the overall stability of the platform and is a real bonus for anyone that it looking to tweak their various memory timings and voltages to try and get the most performance possible.

One important note about the overall performance of the Ripjaws PC3-12800 memory kit is that these are rated with a two memory modules, dual-channel configuration. Using an additional two memory modules will likely cause the memory performance to decline from the need of a high command rate.
