This CT6670 Voodoo 2 from Creative suffers from bad solder joints. The debugging tool mojo reports an incorrect number of TMUs as well as wrong memory sizes for each chip. I thought a simple reflow of the solder around all 3Dfx chips would solve the problem - but that wasn't the case. This Voodoo 2 card has a lot more issues than I initially thought!
