Design and layout Looking at this board, you unwittingly recall the very first NV40 samples. This is no wonder because the PCB design of Gigabyte 6800Ultra is an absolute replica of NVIDIA reference design, and needless to say, the board is made on green textolyte. The cooling system on this board also fully matches that we are used to seeing on NVIDIA reference boards. The difference is merely in Gigabyte's name engraved on the radiator's lid, logo sticker on the fan, and the changed color of the lid itself. In all the other respects, nothing has changed. The same technical implementation of the cooling system, so many times described in varied reviews. There is a separate aluminum radiator on the GPU, a heat pipe of original design with a radiator on the video memory, and a lid with a fan mounted into it - that's just the structure that covers both the chip and all the memory circuits on the front side of the board.  GPU 6800Ultra offers nominal frequency 400 MHz, which fully matches the frequencies declared by NVIDIA for its product. Judging by the marking, the chip was made on the 23rd week of year 2004 and has revision A1. On the frame that NVIDIA started using to preserve the chip against damages, there is a label showing that it is a genuine GeForce 6800Ultra.  There is 256 Mb DDR memory with a 256-bit data transmission bus assembled with eight K4J55323QF-GC16 chips made in the BGA form factor, of 1.6 ns access time, which is equivalent to the operating frequency 625 MHz (1250 MHz DDR). For 6800 Ultra, the declared memory frequency is 550(1100) MHz at which the memory on this particular specimen is running. Therefore, the memory offers a good guaranteed overclocking potential. All the eight video memory chips are positioned on the boards's front side.  Drawing your attention at the very two connectors for additional power supply - a distinguishing feature of 6800 Ultra, around which there were so many arguments, with quite serious claims imposed upon it. Putting it straight, the capacity of the power supply unit is 480 W originally recommended for these boards shocked many, but it turned out later that the card is able functioning safely and even overclocking thus allowing to use quite good-quality 400W PSUs. So you can stay absolutely assured and not panic about this.  On the board, there is the following set of outputs - two digital and one TV-OUT.  That was a candidate for the title of absolute champion of the ultrahigh-end video accelerators sector to date. Now let's look at ATI's retaliation - X800XT in ASUS make.
