Today, the enthusiast angle is still a strong driver for DDR2 development, but manufacturers are basically trying to achieve better performance through radical cooling designs (such as OCZ's Flex-XLC hybrid cooling memory) and hand picking chips to ensure overclocking capacity. You can find enthusiast DDR2 memory in the speeds of 1200MHz, but the last real DDR2 specification to meet the JEDEC standards was DDR2-800. Every other high-speed DDR2 memory you see today above DDR2-800 can be considered custom factory-overclocked memory. Their speeds, timings and voltage requirements can vary from manufacturer to manufacturer. For example, the JEDEC standard for DDR2 specifies operating voltage of 1.8V. However, all DDR2-1000 and above memory modules run outside of the specifications anywhere between 2.1V to 2.35V in order to function properly.

Then in May this year, Micron announced sampling and production of the first DDR2-1066 chips that are actually able to run at a stock voltage of 1.8V through their 78nm fabrication process. This is the first big announcement for DDR2 memory as it could possibly see the setting of a new official JEDEC standard for DDR2 memory and running into favor with AMD, which will not be moving to DDR3 till 2008 at the very earliest. Micron's new DDR2-1066 chips operate with a CAS Latency of 7.0 however, which may very well cripple its performance advantage seeing that standard DDR2-800 memory have dropped to CAS 4.0 and even 3.0, while regular enthusiast DDR2-1066 in the market run at CAS 5.0.

This is where Micron's German rival Qimonda AG comes into play. Through their AENEON brand, Qimonda has essentially beat everyone to the punch by launching their new AENEON XTUNE DDR2-1066 memory into the retail channels. The XTUNE is the performance model of AENEON's memory lineup and this DDR2-1066 memory is not only guaranteed to operate at a stock 1.8V at 1066MHz, it also runs at CAS 5.0 latency and carries NVIDIA's Enhanced Performance Profile (EPP) timings. That's a triple bonus in a single stick of RAM and we intend to put the AENEON XTUNE DDR2-1066 through its paces to find out just how well Qimonda's newest DDR2 wonder-RAM will fare. In this review, we will be testing the AENEON XTUNE DDR2-1066 2GB dual channel kit (AXT760UD00-19D).

Mention 'black pearl' these days and you'll probably conjure up an image of a dilapidated pirate ship and a half-crazy Johnny Depp. However, a natural black pearl (as in real pearls - the jewelry kind) is incredibly rare and often used as a term to describe something that is highly limited and valued. In the motherboard world, ASUS on rare occasions, tend to release a special edition of a motherboard that has been engineered to the brim with features and special high-quality components that sets it apart from their regular boards. These are known as the ASUS Black Pearl Edition motherboards.

Now, if there's one thing in PC marketing that is constant, it is the over saturation of a certain branding till it becomes somewhat trivial. However, the ASUS Black Pearl Edition is truly a rarity. The last Black Pearl motherboard from ASUS was the P4PE back in 2003 based on the Intel 845PE chipset (which we've reviewed here too if you're interested to take a peek). Now, after a four year hiatus and five chipset generations later, ASUS commemorates their 18th anniversary with brand new third generation series of Black Pearl Edition motherboards. Presently, ASUS has taken their current two flagship P35 motherboards, the P5K Deluxe and P5K3 Deluxe and transformed them into the P5K Premium and P5K3 Premium Black Pearl Edition boards respectively.

As it can get a little confusing separating ASUS' large family of boards, we'll go through a short background on the two boards. The ASUS P5K Deluxe and P5K3 Deluxe are really two versions of the same motherboard, the former exclusively supporting DDR2 and the latter, DDR3. Both these boards have appeared in our various past articles (ASUS P35 "Bearlake" Preview , ASUS P5K Deluxe and A DDR3 Story ), so www.hardwarezone.com readers should be very familiar with the original ASUS P5K Deluxe and P5K3 Deluxe by now. Since we've directly reviewed the DDR2 based P5K Deluxe before, we've decided that it would be much more interesting to have an in depth look at the DDR3 variant instead. In this article, we will pick apart the ASUS P5K3 Premium to see if ASUS still has what it takes to deliver a real Black Pearl.
