Kingmax DDR-400 SDRAM Review - Specifications

Just recently there has been a great deal of talk about DDR-400 memory. Talk regarding supply for current and future chipsets including nVidia's nForce2 and the SiS 648. Kingmax were the first to bring DDR-333 memory to the market and again they have come out first with their DDR-400 SDRAM. There's been talk of poorly performing PC3200 memory from the Taiwanese company before now, Kingmax confirmed to us these were not modules with actual 5ns chips like the authentic DDR-400 memory from Kingmax which Cameron "Sov" Johnson bench tested today!

As you can see, Kingmax has done its work on producing a stable memory module. While being rated at CL2.5 for DDR-400, this memory is rated at CL2 for DDR-333 operations, so very easily you can use it on any current DDR-333 board with a minimum of fuss and a full burst of power.

 

Now that we have looked at the specs, lets take a look at the module!
