HIS Excalibur X800 Pro IceQ II VIVO Review

The Excalibur X800 Pro IceQII VIVO Edition is clocked at 475Mhz
core and 900Mhz for the onboard 256MB GDDR3. The suggested retail price for this
card is at US$ 479 while their XT edition is going at US$ 539. At the front of the
card, there is the IceQ II cooler which cool the VPU and 4 memory modules while
there are another 4 memory modules located at the back of the card. The X800Pro
VPU on this VIVO card is actually using the X800 XT core where the bridge is
intact (connected) therefore the soft mod can be performed to turn this card
into an XT. Another good point of this card is that it is using the Samsung
1.6ns GDDR3 memory which has an effective data rate of 1200Mbps/pin therefore
the memory certainly has some more lee-way to go.

On the back of the card, there
is the ATi Rage Theater chip providing encoding and decoding feature as well as
Video-in functionality. The Rage Theater video encoder converts images of
Windows, MAC OS, DVD movies or games into all NTSC and PAL formats for TV
viewing and the Composite and S-Video analog inputs in NTSC, PAL, and SECAM
format are converted into high quality, low noise digital video for a sharper


IceQ II Cooling System

The most distinct feature on the card by one look at it is the
definitely the Arctic ATI Silencer 4 cooler, part of the IceQ II cooling system
which draws cool air from inside of the case and propels the warm air out of the
case. This cooling method is clearly effective as the warm air doesn’t gets trap
within the case and thereby warm up the graphics card and the rest of the PC
components. HIS claims that this cooling system can effectively lower the GPU
temp by as much as 11 degree and far quieter too. The copper plate acts as a
heat spreader is housed onto the VPU and the memory to draw the heat away fast.
There are some aluminum fins located on the copper plate for the cold air to
pass through and channel the hot air out of the case. Also there is an aluminum
plate on the back of the card to cool the 4 memory modules. The only downside of
this cooler is that it takes up two slots and it is longer than the card itself.
It may causes problem if the case is small especially for SFF.
