Now looking back in hindsight should of ordered 2 chips, could of tried both and even soldered 1 on top if they both worked to improve the pass through. This is a second 3d monster I have so not currently in use but yes my aim is to have a backup/collection that works 100% I am very happy that it is …

The chip came today and I installed it, the resistance values look good and looks like my previous shorts are gone. Turned on the system and unfortunately no video but I can hear the system booting. Before I gave up I tried starting with vga direct into 2d card, started a 3dfx game and then manually …

I built a socket 7 system not long ago and looking for some 3dfx games that will run good on my setup and let me explore the 3dfx world. Back in the days I never could afford a 3dfx then after that jumped onto a Riva tnt when I got a slot1 Celeron so I am now finally enjoying a 3dfx. My system is: - …

I ran one without a heatsink and after a few minutes I would get artifacts and high pitch squeel, the cpu will die. I would trust what is printed on it

I know what your saying, the input side of the switch needs to connect to the output side to the vga out, just like the chip would switch that output - for the 3d. Ofcourse there will be a vcc pin and if connected to the wrong pin it will smoke it. So I have no idea at this stage which input goes to …

I see, I do remember now reading that at the very start but got excited and jumped the gun. Its not straight pin to pin connection from input to output? (where chip was) That would be too easy?

If I had that hardware would be a good test to see if it works with the chip off. I have ordered the chip from ali express for about 3usd so now it will take a few weeks you don't need a switch to test it, just manually move the monitor cable after the game switches to glide mode it certainly won't …

for 3usd its worth the gamble but I am of the same opinion. I don't have any other broken 3dfx, anybody have any idea on what other old cards or electronics I could find this chip?

I took off the bus switch chip, now the resistance on cvdd is .450~ looks much better! it is .350~ on the working card but with the bus switch naturally it won't be exactly same. Now the big challenge will be finding a replacement

Pin 12 is short along with many pins between 1 and 12. Also I found shorts on one of the main chips on the front https://i.ibb.co/SnVwqqG/Screenshot-20210619-001558.png I got shorts on cvdd and dvdd which are clock power inputs according to the pinout. I guess from here it comes down to removing …

I have a identical 3d monster that works so today I did a quick comparison side by side. What really sticks out is the resistance from the output and input vga port pins to ground. So on my working card I get alot of pins that show .500 resistance to ground, on the faulty one it shows .50 .. this is …

I had a power surge and it killed my 3dfx monster along with a s3 virge, also my kvm switch and monitor. The motherboard and rest of the system survived. Anyway none of the dead parts show any physical signs of damage which makes it so hard to figure out if its salvageable. I know there is alot of …

When I power it on the green led is on steady, once I turn it off with the power button system shuts off but the green led pulses. If I …
