So, high-frequency DDR2 memory does its job well on the Core 2 Duo platform. A majority of PC2-800 and faster modules currently offered by the manufacturers of overclocker-friendly memory prove to be stable at a frequency of 1GHz and higher, often with not very bad timings.

Modules based on Micron’s chips stand out among the tested products. Such DDR2 SDRAM modules are not only capable of working at ultra-high frequencies, but are also stable at frequencies above 1000MHz with 4-4-4-12 timings. So, memory of that type can be viewed as versatile because all DDR2-800 SDRAM for overclockers available on the market supports timings no better than 4-4-4-12.

Also remarkable is the fact that you can be as lucky as to make your Micron chips based memory work as DDR2-800 with 3-3-3-10 timings, but there is no absolute stability in that mode. Quite a lot of applications would run normally, but special-purpose heavy tests that we use to check out memory stability, especially S&M and Prime95, report possible problems. Overclocker-friendly DDR2 SDRAM also reacts well to a voltage increase – its frequency potential grows up at that. The manufacturers use this property to produce their enthusiast targeted memory. As a result, all the memory kits we tested in this review could work at 1067MHz, their voltage being increased from JEDEC’s 1.8V to 2.2-2.3V. Some memory on Micron chips could even be clocked at a fantastic 1150MHz at their default 2.2V voltage!

The Corsair TWIN2X2048-8500C5, OCZ DDR2 PC2-8000 Platinum Extreme Edition and Patriot PDC22G8000+XBLK memory kits are undoubtedly our choice. We recommend them for all enthusiasts who are going to overclock their Core 2 Duo systems. These versatile 2GB kits of DDR2 SDRAM help achieve maximum performance upon increasing the FSB frequency to 400MHz and higher.
