Unfortunately, Corsair is one of the companies that equip their modules in the medium price range, the first revisions with very high quality chips (eg Micron) and thereby reap excellent marks in the first test reports. "Keep the cash", the following revisions to cheaper chips are stocked, that satisfy the promised Corsair values, but rarely much room for enthusiasts leave some. Colorful heatspreader one could give it, but you know precisely what many customers check and naked memory modules are frowned upon in certain circles, even if they, as thus had no technical disadvantages in this case.
The memory kit is undoubtedly high quality, solid and always reliable. Currently, however, ordinary chips of Promos, Elpida and Co. are installed. That you just have to know beforehand to expect miracles and then disappointed.
Who wants to come to low-quality modules that prepare a long-term enjoyment and adheres to the manufacturer's instructions, which will certainly be very happy here. Overclockers and people who want to get the most out of their hardware, I would rather advise against these modules.
