Unfortunately I wont recommend any ram chips, due to only ones I found are selling by only one Chinese guy. There is possibility they may not work, may be broken/fake, there is not good photos on auction. If you still want modify your velocity card, then take following things into consideration:
* you got most info from previous post from @Thermalwrong
* you have to resolder 4 chips and set few resistors to proper position to unlock missing signals
* you have also re-set additional strap resistors to configure new size of ram and memory banks - I have done this but I wont release solution until I test it in real world
* re-setting straps requires cuting/wiring traces on pcb, also requires removing resistors array + replace some of them to lower size from 603 to 402 - without proper skill/tools and microscope it may be difficult and probably you'll destroy your velocity
* you need to buy new ram chips or gather them from donors

If you still wanna do this upgrade, just do some basic math:
* velo has 8MB vram in 4 chips, it means 8/4=2, actually 2MiB per chip, MB is just marketing, MiB is in realality 1024*1024 bytes
* so each chip has 2MiB, organization is 256Kx32x2, you want to change each to twice more capacity, so you have to look for 512Kx32x2
* find datasheet of your existing chips and find dedicated ram, check pinouts on both chips, size of the chips, raster etc., check params, speed etc.
* when you'll find proper replacements, then search seller on ali/ebay and check description/photos, there is always risk you can buy crap
* now resolder ram chips, move resistors, set straps
* test stuff, if you did all in proper way, and your chips are good, then everything should work from a shot
* this is not easy task, most ppl think it's just like a fart, coz it's just replacing mem chips... well, it's not, just do it yourself 😉

Cheers 😀

Yeah, just my opinion, but I think the 8MB cards are totally fine as-is if you use the fixed glide2x.dll. There are many thousands of 16MB Voodoo3 cards out there if you must have one... and the price premium over an 8MB card will definitely not be enough to offset all of the work (and parts costs) needed to upgrade one. If you are playing older games that don't use a lot of texture memory, the 8MB cards are super fast and have plenty of memory. Also, considering that, to my knowledge, all of these cards are AGP, there are tons of other non-3Dfx options available if you need more than 8MB of VRAM. A Geforce2 MX (128bit) will easily outperform any of these and are extremely abundant and cheap.

If someone is skilled with this kind of thing already and wants to do it as an experiment, then fine... but don't waste a perfectly good 8MB V3 by doing unnecessary Franketstein stuff on a working card that is relatively uncommon.

... a good candidate would be a card with a bad or damaged memory chip since it already requires some work to get it running, but even then, I hope you know what you're doing. 😁

And I'm somewhat in agreement with this, it's interesting from a technical PoV but from a cost / usage perspective the Voodoo 3 16MB cards are more common. The cost of adding RAM to this Velocity 100 card ain't cheap unless you already have lots of experience with and tools for soldering.
I did it for the MS-6168 because that's been on my bucket list for a while, maybe a 16MB Velocity 100 is on someone's bucket list too 😉

Ah I thought so, I couldn't see any spot where the resistor for the memory chip count was optional. So it's probably in one of those resistor packs and would require surgery to alter. I don't know, I don't and won't have one of these cards 😀

@smola Thank you for clarifying difficulties during this upgrade. I'm ready to risk and i'm ok if i'm failed, now i'm trying to find chips for good price, if i found i will compare to specs with chips already on velocity. If i complete first stage. Will try next, hoping i'm not failed)
And to others, it's not about performance per dollar story, it's just for fun, but of course i agree it's better to trying this upgrade on Velocity 100 with broken ram chips.

Great! Good luck with upgrade, fingers crossed! 😀

Velocity 100 with 16MB (4хKM4132G112) works fine with BIOS V3-1k 2.15.05-SG; V3-2k 2.15.03-SG.
How to modify the bios Velocity100 2.15.06-SG, so that memory 16MB is detected at startup?

Before bios mod I'd check strap resistors to setup proper ram config. Clean pcb, it's dirty, solder missing ele cap C79, usually 10uF.

I flashed a BIOS VELOCITY 200 AGP SG 2.15.06

Hi! I want to be sure, i'm waiting to receive a 3dfx voodoo 3 velocity 100 i just bought at good price. So i just have to copy paste this fixed glide2x.dll in all glide games i played ? Right ? Does it works with Tomb Raider in pure dos to add the original fog ?
Every graphics effect will work perfectly normal like a original voodoo 3 16mb ? right ? I was about to buy a voodoo 1 to have fog working in tomb raider 1 in dos, so it wont be necessary ?

If i use this modded glide2x.dll, can i still mod my velocity 100 with this bios mod ? V3_velocity_mod.7z

Voodoo 3 Velocity 100\200 and drivers

Now, did someone know if it necessary to hack the registry for unlocking TMU 2, if you already applied the v3_velocity_mod bios and you installed the normal voodoo 3 driver after that ? Thanks for answers

You only need to use the file GLIDE2X.DLL-v3-vmem-8mb-bug-fixed-by-smola.rar
No BIOS modifications and hack the registry are required.
User smola has done a great and impressive research that has completely cleared up the issue of the 2nd TMU in Voodoo3 cards with 8MB memory.

I'm not sure about the fog control in Tomb Raider. I haven't seen any fog settings in this game. Also, it's a DOS game and uses the VoodooRush patch +glide2x.ovl. It seems to me that the game Tomb Raider looks exactly the same on any Voodoo1-Voodoo5.

Thanks for answer. i read a few times that you need a voodoo 1 to activate fog in tomb raider in glide mode and the the fog is not working with any other card. When i was young i remember to have seen the fog effect with my voodoo 1. I played it 2 years ago with a voodoo 3 16mb and i didnt see the fog anywhere in the cavern.

ok it was not fog that was exclusive to voodoo 1 it was the shadow. i asked the question on the ai google search:

No, the fog effect in the original MS-DOS version of Tomb Raider does not only work with a 3dfx Voodoo 1 card; while playing on original 3dfx hardware will add special graphical features like shadows, the fog itself is a standard effect in the game that would work in software mode or with other hardware. The fog effect is not tied to a specific 3dfx card, though some advanced 3D effects like shadows were exclusive to the original Voodoo hardware.

No, the blob shadow effect in the original Tomb Raider for DOS does not work on Voodoo 2 or Voodoo 3 cards without the "Voodoo Rush patch," which introduces other visual bugs. The shadow only functions correctly on a Voodoo 1 card or with a "Voodoo Graphics patch," though the latter does not work on later Voodoo cards and has its own set of compatibility issues.

How it Works
Voodoo 1:
The shadow effect is exclusive to the original 3dfx Voodoo 1 card and only works with the 3dfx Glide API.
Voodoo 2 and 3:
These cards do not support the shadow effect as the original patch was designed for Voodoo 1.
Voodoo Rush Patch:
While this patch allows the game to run on Voodoo 2 and 3, it causes problems with shadows, transparencies, and other visual elements, notes philscomputerlab.com.

Ok, thanks, and I'll take a closer look at the shadows. As far as I remember, problems with displaying the shadow under the main character of the game TR1 arose in Glide emulators, like djVoodoo
P.S. Launched on Voodoo1:
patch for Voodoo1 - there is a shadow;
patch for Rush - there is no shadow.

ah cool, thanks for pictures

( it should be in my head 🤣 but i think the fog quality was better with the original voodoo 1 than my old Diamond Stealth 2 S220 rendition verite or voodoo 3, if you want to verify that 😉 )
