"The Corsair CMGTX4 and CMGTX7 were two of the fastest RAM kits available at the time; they carried with them a huge price tag and 'till today, the speed on the GTX4 kit is just insane. Both kits are dual channel, but neither would achieve their rated speeds. While overclocking on the Z68 platform is great, its memory overclocking is limited and actually not as strong as the older P55 when it comes to raw MHz. Having unfortunately admitted defeat on these two kits, I never got around to actually looking at them, because we couldn't get the default speeds.
This has all changed, though, with the release of the new Bulldozer platform. Today we've thrown these two kits in our testbed with a couple of other kits and CPU / Chipsets and we're able to see the kind of speed we're able to get out of the kits here while also looking at the evolution of memory performance from the older 1100T to the powerful 2600k today. We just wanted to have a bit of fun here today and concentrate on the synthetic side of things, so we just fired up AIDA64 to see what kind of performance could be had in a MB/s capacity."
