SUMMARY: 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!
The module itself is much smaller compared to a standard module. Measuring only 1.18 inches this module is ideal for low profile systems, servers and of course overclockers and concept PC’s, where space is usually tighter since double sided modules come with 16 memory chips in total. This means you can’t use this module in the third DIMM slots on Intel I845D, E and G motherboards - but then again very few can.
As mentioned, Kingmax uses 16 chips on all of their modules. These chips are produced for Kingmax by Kingpak, Kingmax’s chip fab plant. The chips are in TinyBGA form, a very excellent packaging technology which reduces heat and increases signal integrity over standard memory modules. This chips are rated at 5ns making them fully 400 MHz compliant, not like some of the previous “DDR-400” reviews we’ve seen floating around.
After all the testing and quality assurances have been completed, Kingmax slap a sticker on the module with serial, lot and batch numbers for reference purposes as well as the speed, size and CAS Latency which is a well known Kingmax trait. What I would like to see for future modules is a new coloring or heat spreader added to the memory, as this would make it more attractive.
As a business owner, or someone responsible for network security within your organization, you need to understand how to prevent attacks and eliminate network weaknesses that leave your business exposed and at risk.
