ASUS Matrix GTX580 Platinum Unboxing Continued... 
Below the primary cooling assembly we see the heart of the NVIDIA GTX 580. There are twelve 128MB Samsung DDR5 memory modules soldered to the board for a total of 1536MB of Memory, to power the memory ASUS used high quality solid-state capacitors and chokes in construction of the 4 phase Digital PWM memory power design. The Platinum also has 19 additional power Phases hidden under the secondary VRM heatsink. With the cooler removed you can really see the depth of a 3 slot wide card by looking at the PCI support bracket.
Asus has taken it one step further with the GTX580 Platinum cooling solution, the heatsink is a remarkable blend of performance and aesthetics. The use of a five extra large heat pipes and 110 aluminum fins provides excellent cooling for the Fermi graphics chip even under extreme overclocking conditions. At the heart of the cooling system is the Direct Copper II Thermal design. The DCUII architecture uses direct heatsink to GPU Core contact of all five copper heatpipes, providing the most effective means of quickly transporting heat away from the graphics core and out to the aluminum fins to be taken away by the dual 90mm high flow PWM fans. The Direct Copper design has proven its self as a very capable cooler, demonstration over 600% increase in airflow and a 20% reduction in GPU Core temperatures compared to reference designs. I must note a large benefit of the dual 90mm fans is the noticeable reduction in noise generated by the cooler, this is apparent when idle and under full load.
The Overclocking area has several previously unseen features like the handy manual fan override. This button pushes the PWM temperature controlled fans into overdrive with a constant 100% duty cycle. Other features found include the ProbeIt read points for measuring direct voltage of the GPU Core, Memory, PLL, 3.3V rail, 12V rail via a multimeter. Located below the red fan button, the + and - buttons are used for on the fly voltage adjustment. Physical voltage adjustment is very useful for increasing or decreasing GPU Core voltage while running a benchmark or when in need of a little extra gaming juice. To the right of the TweakIt buttons are ten LED lights that display voltage status in a similar way the GPU load indicator operates, all 10 light will give a red light status indicating maximum voltage is being applied to the GPU core.
The above picture shows us four open circuits, easily accessible and conveniently labeled. For extreme users and ideally LN2 Overclockers the shorting of these circuits by use of solder, conductive pen or variable resistor allows the card to operate with Over Current Protection disabled. Disabling OCP is needed to achieve frequencies above 1300MHz core clock. If this is not disabled the cards internal fail safes will trip and protect the card from drawing too much power under load by shutting down the card. The two center circuits are shorted to increase the GPU PLL and PCI express lane reference voltage. The very bottom circuit is a surprising and new mod for graphics cards. Power PWM Frequency refers to the switching frequency of power supplied to the graphics core. Shorting this will double the switching frequency from 250KHz to a staggering 500KHz. The higher switching frequency provides a faster reaction time for the power phases to meet the varying GPU power demand. These mods help the GPU surpass clock speeds upwards of 1600MHz or more when operated at below freezing temperatures for example with Phase change cooling systems, Dry Ice, Liquid Nitrogen, or some lucky Canadians.
Positioned at the far back of the card are two 8pin EPS 12 volt PCI express power connectors used to supply additional 12 volt power to the graphics card for maximum graphics stability and overclocking potential. Directly behind the power connectors are two sets of LED lights. These lights display the status of the 12v auxiliary power connectors and can be helpful in troubleshooting faulty cables or connections. To the left of the 8pin plugs are the six ProbeIt voltage read points I discussed earlier.


With the Cooling assembly removed we can clearly see the unprecedented 19 phase Power for the GPU graphics core. The Matrix Power design consists of Japaneses super alloy capacitors, Super Alloy
Chokes that act as electronic filters,
Drivers and Digital super alloy
VRM's "Voltage Regulator Module". Above the GPUs 19 power phases is an additional 4
power phases for the GPU memory The extra power phases help with energy efficiency, power quality and overclocking potential. The reliability of the video card has been improved with lower power component and board temperatures. Look closly and you will see four gold caped white fuses, these are used to limit the total current draw of the card in order to prevent fatal damage to the VRM's and other components.
To the upper left we see two NVIDIA
SLI gold fingers or "Bridge connectors" these are used to connect multiple NVIDIA graphics cards for 3 & 4-Way SLI. The bottom of the card is home to the 164 PCI express 16 pins supporting a full bi-directional 16x graphics lane. Take a step back and gaze upon this naked card for all its beauty, admire this engineering feat of victory as ASUS engineers have bundled an unbelievable amount of performance and ingenuity into an all inclusive gift.
The Matrix GTX 580 Platinum has renewed my joyful ROG spirit within, Bringing back the euphoric moments of my favorite ROG products. ASUS has truly outdone itself, I must thank all of the employees of ASUS for creating a product worthy of the enthusiast community!
