Nothing annoys me more than the inability to review a product. It doesn't happen very often, especially when we move outside the realm of the product being DOA or it not making it through all our tests. Two products have eluded me over the last twelve months, though, and what disappoints me more is that they come from one of our favourite companies to deal with. 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.
