BGA memory isn't the easiest thing to understand so we will simply explain it in a way most people will understand.
Normal memory is known as TSOP, this is seen on the SuperRAM series form Kingmax as well as 99% of other DDR memory modules on the market. This memory is connected to the PCB (Printed Circuit Board) with little legs on the side of the memory chips. BGA or Ball Grid Array works with lots of little solder balls on the memory PCB and the back of the chip which are in turn joined together and this is how the memory is attached to the PCB.
Some people may not understand how this is more beneficial but thanks to the shorter distance between the PCB and chip being of absolute minimum, you will wind up with the best possible connection and the best factory yields.
All modules are 100% Dual Channel compatible and work without a hiccup on both Intel and AMD systems including the newest AMD Athlon 64 system which is known for being quite picky on the memory side of the show.
One other thing that people will also notice on this module is that it doesn't come with a heat spreader. Some may think that due to the high speed of the memory, a heat sink is a must. This is another benefit to the BGA technology. The memory chips operate at a cooler temperature and there is no reason for a heat spreader to be included as part of the package.
Having said this, the majority of the time heat spreaders are just included for looks. So it's not too much of a concern. It might have been an idea for Kingmax to include a fancy looking heat spreader as customers may think they are missing out on performance from the Kingmax module due to it not requiring any additional cooling.
You can't get anywhere without overclocking and we intended to find out just how far we could get both sets of modules by pushing the FSB of our Pentium 4 processor as high as possible. As soon as we pushed our samples to 2.9 volts (and above) on the ABIT IC7 MAX3 motherboard we ran into booting troubles - this made 2.8 volts our limit and at this DIMM voltage we got the DDR-466 to 488 and DDR-500 to 516.
Before we get onto the benchmarking it is worth noting that for some reason we ran into some trouble running 3DMark at some of the above speeds. Apart from in 3DMark, the modules were 100% stable from just running word to benchmarking and playing the brand new Unreal Tournament 2004 demo.
