A-Trend Helios 3D Voodoo
VP-503 
This is my first 3Dfx card I bought (and still have). The card has been purchased on a fair named 'HCC Dagen' and did it's job for quite a while in my systems. At the time I bought it the card was brand new but the technology was aging. If I recall correctly it was 2001 when I bought this card for my Intel Pentium II.
Later on I sold the Pentium II as it didn't run as it should be (Deschutes 350MHz on a 440LX chipset running at 83FSB / 291MHz). My trusty Intel Pentium 133 @ 166 (83MHz FSB, 430TX chipset) was back in action along with this 3Dfx card. Tweaking everything on the PC made it flew like madness. Some of the SET variables I used to tweak the 3Dfx card are: SET SST_SCREENREFRESH=75, SET SST_GRXCLK=57, SET SST_FASTMEM=1, SET SST_FASTPCIRD=1, SET SST_VIDEO_24BPP=1, SET FX_GLIDE_NO_SPLASH=1, SET FX_GLIDE_SWAPINTERVAL=0. Also setting the GAMMA correction lower (default is 1.3) resulted in an increase of the image quality.
As seen on the pictures this board has a yellow dot (sticker) on the back. Along with the AQA sticker on one of the D-SUB's this is a characteristic of A-Trend. Some Voodoo Graphics cards have a red dot. The blue dot can only be found on the Voodoo Rush. A-Trend produced a lot of boards which other companies rebranded. This Helios 3D card was sold using the name 'A-Trend Helios 3D'. Other cards were sold with a total different name but the comming A-Trend markings reveal their true identity.
