These include, but are not necessarily limited to:.

Although the PCB’s silkscreen does include an outline for the pin headers used to control conexxnt reference designed daughter board, Guillemot has chosen not to include the header but rather to incorporate the video-out chip on the back of the PCB.

It seems that current memory cpnexant can not run faster than around MHz DDR fonexant maintaining stability without some form of cooling. This page was last modified on 27 Decemberat Unfortunately, Guillemot chose to attach the heatsink and fan to the GeForce2 Pro core with only the use of side clips and a non-adhesive thermal pad.

All video encoders are connected to and controlled via the SMBus. In order to make room for the BT chip and the traces that run to the output connector, Guillemot had to move the power components normally present in the upper left hand corner of the card.

We are not sure if the reference design calls for these heatsinks Guillemot has used them in the past where they were not required but we suspect conexnat the memory heatsinks are called for by NVIDIA. Both conexnat seem to require memory heatsinks in order to maintain proper operation of the memory.

As you can see, the BT chip forces the power components to the back of the card, extending it a full inch. In the case of the GeForce2 Pro, as well as the GeForce2 Ultra, this cooling comes conexannt the form of memory heatsinks, in this case blue ones.

There is also a sister model FS without the Macrovision capability. There is also a sister model CX without the Macrovision capability. They are, however, not register-compatible.

Going along with the blue motif, Guillemot includes blue memory heatsinks RAMsinks on each of the eight memory chips. It seems the only way to find out more is through reverse-engineering techniques. This is because it is no longer necessary to produce a separate PCB in order to allow video-output. Views Read View source View history.

Two of the video encoders Conexant CX and Focus FS also have extensive scaling br869 filtering functionality, which allows for overscan compensation in desktop-style “TV out” usage.
