3Dfx Voodoo Memory Upgrade - 6MB MOD (Part 1)

Рет қаралды 23,332

Күн бұрын

Did you know that there were Voodoo 1 cards with more than 4 MB of memory available? I didn't know back in the day, but there were models with 6 MB and 8 MB - probably at horrendous prices!
With the help of PCBWay, I created a PCB mod which allows to upgrade a Maxi Gamer 3D Voodoo 1 to 6 MB and potentially to 8 MB. In this video, we are going to double the texture memory from 2 MB to 4 MB.

Well, guess what, I am working on the second memory expansion board right now! Will check Unreal as well. On a Pentium III 1GHz, I didn't notice any difference between 4 MB and 6 MB. 3dfx_Aslinger tested on a Pentium MMX 233, so maybe on slower systems the extra memory does make a difference!

Most of the people who may have claimed no performance benefit never owned a higher memory model and base their believe on some article. As you said, it may depend on the game. I tried Unreal and didn't notice any performance difference, but maybe Quake II or Tomb Raider will - we will find out!

For my understanding: Those new memory chips use the power supply of the existing chips - which probably already have decoupling capacitors. I guess the existing capacitors are good enough for 4 chips, but do not provide enough capacitance to filter the power supply for double the memory chips.

I have completed a very spicy mod job like that recently, where i soldered bodge wires to 5 subsequent legs of a tqfp100 chip. I didn't use magnet wire, since i happen to hate it with a passion, but wire wrapping wire AWG30, which is PVC sheathed, which is not ideal, but it worked out OK. Such wire you can run directly to the connector, it won't mind.

Tried a bunch of drivers and some worked with some games and others with the rest... But some with the original miro driver just disabling the extra memory. I remember Carmageddon was one of the problematic games... But there's not much info on the subject... Otherwise I would upgrade all voodoo cards to the full 8mb! :)

@spavatch Жыл бұрын

@@bitsundbolts - I have no idea why they ditched the idea either, I mean it wouldn’t make the card more expensive than the same thing applied on a common Voodoo2 card so it was an odd place look for cost cutting. Instead, it appeared only on some of Quantum3D units and they were as non-consumer cards as they get, priced well above standard Voodoos, even those higher end ones. Put together they formed what was called a ‘DB’ card (as in Dual Board). As such ‘rendering combines’ would most likely approach the $2000 back in 1997 I’m not surprised they didn’t come up on anyone’s radar back in the day and never existed in wider audience’s mindshare. The 4-chip cards you’ve seen are indeed a thing, they’re a further development of the idea bearing the ‘SB’ moniker (as in Single Board) and are basically two Voodoo1s put together. There were also so-called Amethyst daughtercards which added a second TMU with its own memory, effectively making it a Voodoo2 running at Voodoo1 clock speed. Putting everything together, either in DB or SB configuration, you’d get a SLI Voodoo1 with up to 20 or 22 megabytes of combined RAM respectively: 2x2 MB for FBI, 4x4 MB for TMU and 2 MB for AT-25 chip providing 2D video, the same as in Voodoo Rush cards, which came on another daughterboard. My brain itches when I think of that 😅

PT3: Combine both boards into one with no need for any jumpers and 2 daughter boards to go over the TMU and FBI with connections to the relevant pins. Then you got an all in one with no microsoldering required.

@bitsundbolts Жыл бұрын

Interesting, There may be some pins however that do not connect to the TMU/FBI chips (e.g. VCC, VSS). Then the board would need to connect to other sections of the board. There are 39 Pins on the memory chips that are passed through to the upper row. Maybe a device (like a frame 3D printed) that just clips around the TMU/FBI chip would help.

Memory wasn't cheap back in the day, so that may have played a part in only 4mb cards for the most part.

@bitsundbolts Жыл бұрын

That is probably the main reason to keep cost as low as possible.

Are there any devices that could go over the TMU directly? Access the address and data lines and route to memory.

@bitsundbolts Жыл бұрын

You mean another socket? Hehe, I think I know where you're going. Some cards do have heatsinks on those chips, that would cause issues. You may also end up decreasing airflow around the chips heating them up further - those TMUs get hot. I think you'd like to achieve somehow better access to the pins or prevent any alterations to the card?

@@bitsundbolts oh, I didn't think about cooling! Yes, they used to make Macintosh upgrade CPU boards that would clip on to the existing CPUs. Maybe a really hard part to find though, because they probably don't use that CPU package for much anymore. But yes, ideally a clip on upgrade with no soldering required.

@bitsundbolts Жыл бұрын

Yeah, would be neat to just have everything clip on. But I think you won't find a socket that you could press over the chip, it would surprise me. Also, TMU and FBI are of different size. Maybe someone could design a 3D printed device that could do it. Or wait until I learn 3D modeling and create something. But then people shouldn't complain if PCBWay is all over my video 😂

I guess the Tmu ram layout is the same on the most common version of voodoo 1 and I mean the monster 3d by diamond. Once the mod goes public I will help the community to relocate spaces to diamonds measurements and I urge all voodoo 1 owners to do the same for all the different kinds of other companies because the mod easy fairly easy. Only one cable to one pin and voila you have 6-8mb ram. 8 mb ram was commodon back in the days, I had in my pc a monster 3d with 4mb and a diamond fire gl 1000pro with a permedia 2 at 8mb.i still have this pc which was my first pc by the way.

What was the total cost from PCBWAY? What I'm seeing looks pretty expensive at $5.00 per board and then $38 for 3 day shipping and $63.56 for 24 hour processing.

@bitsundbolts Жыл бұрын

Shipping cost depends on where you live. Production of those 10 PCBs is 5 USD and took 4 days to manufacture. If you get the coupon when signing up as a new customer, you get the PCBs for "free". I selected the slowest shipping method which was 12-13 USD to UAE/Dubai (I actually paid for that at checkout) and delivery time was 11-33 business days. Full disclosure, PCBWay upgraded my delivery for free to FEDex, which would have costs 23 USD to UAE, and reimbursed the money I paid for shipping in form of coupons. Delivery took another 3 days. So, to UAE with 11-33 business days delivery, it would have cost 12-13 USD with signup-coupon, 17-18 USD without signup-coupon.

I have found 3DX1000 card out in my cupboard. It has identical footprint and color to the card presented. The imprinting on my card adds "with TV option" but I couldn't find any difference to the card presented: no extra connector or header so I really don't know what the "TV option" means. My card is from "Volcanic" and "VOLCANC" is printed on the board. I have also Volcanic manual including a CD with drivers, Voodoo Graphics user's manual and another CD labeled "Software Driver Version 1.318-98". Manufacturing date of my board is 9923 (where yours is 9744).

Why not solder two sockets together without the PCB ?

@bitsundbolts Жыл бұрын

Yes, this crossed my mind, but you have to solder pin 14 together of all memory ICs for TMU and two memory ICs in pairs for the FBI mod. Just stacking another memory row above the existing ones is not enough. A jumper on a PCB with correct wiring makes this a lot cleaner.
