Very nice PC. I hope I also get lucky and stumble across a cheap K6-2+ or K6-3 some day, the 64MB cacheable RAM barrier on my 430TX/K6-2_400/Win98 PC really bugs me 😒

Can you comment on your intention to switch to Voodoo ?

I never had good experience with VIA chipsets.
Wonder if you have some observations that you can share ?

In general, what do you think about K5 CPUs compared to their counterparts at the time ?

Good stuff.

I just read that voodoo games can play in win98. And the voodoo card works normal vga in dos.
I never really had any luck with AMD CPU’s back in 1990’s So I always used Intel.
But I must have been doing it wrong because they work fine with the right hardware.
Intel is my CPU of choice however.
I just read that the AMD CPU’s work best with VIA chipset and for gaming in DOS / Win98.
I do think Intel based computers are more stable and reliable from my experience.
However as of today I have not had any problems with these AMD CPU’s.

Hey. That's a tremendous build you have going on. I have something similar. The CPU is actually a K6-III+ rather than a K6-III. Much better at overclocking and no issues with caching RAM. Keep us posted on this great build!

Oh, It is a K6-3+ 450.
I only wish I knew how to set the motherboard jumpers for 550mhz.
But 500mhz. will have to do for now.

I ordered a 60mm x 20mm cooling fan for the Voodoo-3 that I want to attach before I install the Voodoo-3 card.
These cards run very hot and the heat is a BIG cause of these cards failing. GPU and RAM Solder joints tend to break from over heating.

You can however try 600mhz: the 2x multi is seen as 6x with the amd k6-2/k6-3(+) cpus. Also with software you can change multiplier (only with + cpu) so that way you can still get to 5,5x.

Make sure to replace the ancient heatsink compound as well.

Actually, The Voodoo-3 card I have has the heatsink glued on and there is no way to remove it unless I try to pry it off and I don't want to attempt that because
I don't want to break the GPU solder ball welds. This is a BIG reason for these GPU's failing is from broken solder ball welds.
So I am just going to attach the fan with plastic ties. Hopefully this should hold well.
The fan is just going to sit on top of the original heatsink. Should provide more than enough cooling.

Do you know how is the difference from your V3 to a TNT2? (in terms of the heat?)

Actually i have installed a Riva128 (has no heatsick) on my super-socket 7, but maybe i will turn back to a Riva TNT2 which is cooled by a heatsink without any fan.
Do you know temperatures?
Would you propose this mod to the Voodoo2's ?

Well, i have several V3 cards that have failed because of over heating and bad manufacturing process.
Solder welds have broken because of over heating in the GPU chip and ram chips.
They need complete rebuilds which means reballing the GPU and resoldering the ram chips.
I know it was from over heating because I can see the heat burn marks.

I received the 60mm x 60mm x 20mm fans and attached them to the Voodoo-3-3000 with thin wire that I purchased at the dollar store.
I did not want to screw the fan into the heatsink because I did not want to put tension on the heatsink as the heatsink is glued to the GPU
and the GPU is solder ball welded to the PCB.
and solder ball weld breaks are a major part of the failures in these video cards. Screwing the fan into the heatsink would have resulted in more weight
for the solder ball welds to compensate for.
I am going to add it to the computer now.
I also have a fan speed controller.
