Post-screen (bootscreen):

Big thanks for Hanksemenec and Mikulaish, this project could never finalized whithout them helping and supporting. Mikulaish provided the extra 32 Mb RAM chips and the BIOS-hacking; Hanksemenec provided tech-info's; I just provided the Voodoo 4 4500 AGP and soldered the memory. After flashing to hacked BIOS I got myself to be the proud owner of this long waited 64Mb RAM single chip VSA 100 video card!
The card is perfect working; all 64Mb RAM are being used. I will post more details as soon as I can spare some free time (I am at work right now...).

I would just like to add that changing the strapping resistor configuration didn't help recognising the extra memory. The only modification needed is in the bios (stricly my opinion for now, don't shoot me if i'm wrong). There is a bit that defines the no. of memory chipsets. It has to be changed from 0 to 1, meaning 2 chipsets instead of 1.

I just posted the necessary changes, and i have just modified it for Osckhar. I'm not that selfish. I don't even own a v4   :). But to be certain of the bios, yours, TM30, would really help. Could you dump and send it to me, please?

hmm amazing that the boot screen shows 64MB of ram, now I wonder how it will do in games :) it should do fine since that the bios does show the True Total Memory Capacity properly :)

Nice work lads. 8)

As you said about the ordinary soldering iron.. it would be suicide hehe

Hello again!
As I promissed, I'm back with some benchmarcking with Voodoos:
For starter, let me say that all the testing was done using 1024x768 resolution with 32 bits colour compressed textures.
The platform for all the tests was:
MB Syntax Via KT 266A ("crap") + CPU AMD Duron 1100 Mhz + 256 Mb RAM Sycron DDR @ 200 Mhz ...
... plus some great toys: enter the Voodoos: Voodoo 4 AGP 64 Mb (recently moded from 32 Mb), Voodoo 4 AGP  32Mb, Voodoo 4 PCI 32 Mb and Voodoo 5 5500 AGP 64 Mb.
No overclocking was used; sorry for the small scores; I'm seeking for a better CPU but I'm preety low on money now...
I was runing MS Windows 98 SE + UnOfficial SP 2.1A and for benchmarcking I used 3DMark 2001 SE 330.
I tested the performance of the 3DFX cards with and without FSAA. The driver used was Raziel64 Evolution 1.01.16 for Voodoo 4/5 and Windows 9x/Me. The DirectX verssion was DirectX 8.2 .
The Voodoo 5 AGP was runing in AGP 1x mode; for Voodoo 4 AGP I used AGP 4x mode and, of course, Voodoo 4 PCI was runing in PCI 33 Mhz mode.
There are the results:

Voodoo 4 AGP 64 Mb AGP4x :
No FSAA : 1576 3D marks

2x FSAA : 803 3D marks


Voodoo 4 AGP 32 Mb AGP 4x :
No FSAA : 1471 3D marks

2x FSAA : 661 3D marks


Voodoo 4 PCI 32 Mb PCI 33 :
No FSAA : 1358 3D marks

2x FSAA : 624 3D marks


Voodoo 5 AGP 64 Mb AGP 1x :
No FSAA : 1950 3D marks

2x FSAA : 1401 3D marks

4x FSAA : 602 3D marks


Feel free to comment on the results I got!

@Komponent: Great job! It seems like the extra memory is really being used! Congrats!
@Gary: Personally, I would really like you to try it out...  ;D The moded bios worked for osckhar so it should work for you as well.

Post by Chosen_One on 22.04.06 at 01:18:23
thanks alot for the bios...but i have a question!

but first of all the point of editing the mem-chipsets! i compared your bios with the original Voodoo4 4500 AGP 1.15 bios...
http://img115.imageshack.us/img115/1750/tdfx18pa.th.jpg

here the details of the bios (4800-4500)
http://img115.imageshack.us/img115/7629/tdfx22rf.th.jpg
you changed:
tBWL BKWR to Pre from 1 to 0
tRL to PRE from 0 to 1
Number of Sgram/Sdram chipsets from 0 to 1

why did you changed the first two values? are they neccessary to gain the extra ram?

Yaaayyy ::)

@ Komponent

Rather amazing those 3D Mark scores :) FSAA x2 on a Voodoo4 4500 with 64MB does more with MAX FSAA that a Voodoo5 with max FSAA, that may be because of the faster ram timings.

Very interesting results  8)

Title: Re: Voodoo 4 mod from 32 to 64 MB RAM: finaly, suc
Post by mikulaish on 22.04.06 at 07:48:42
About the first two values: they do not need to be changed. This is my bad. Tdfx bios editor chages stuff by itself sometimes when something is edited. I changed those values back to default and uploaded again. In the DVI version this was corrected in the original package as well.

Title: Re: Voodoo 4 mod from 32 to 64 MB RAM: finaly, suc
Post by Chosen_One on 22.04.06 at 13:42:56
maybe you can post a benchmark with these two values changed and not changed...maybe they don't change anything...maybe they change something....

that would bring the real performance of +32mb...without any  changed timings etc...


Title: Re: Voodoo 4 mod from 32 to 64 MB RAM: finaly, suc
Post by mikulaish on 22.04.06 at 17:16:01
First of all I don't own a V4. Komponent owns the homemade V4 4800. As i said before, the DVI bios had the default timings in the original package. Osckhar did his benchmarking using the correct timings in the bios, and as you can see, there is a difference between 32 and 64 mbyte.  Still Hank's opinion would be wellcome and very much appreciated, but it seems to me that the extra memory is being used.

The BIOS that I used for testing on my moded Voodoo 4 with 64 Mb had a few changes oposed to the standard 3DFX 1.15 original BIOS, other than the necesary change of the bit that controles the number of memory banks. Those differences occured not intentionaly and they were fixed into the latest "relese" of the 4800's BIOS. This last one, publicaly available by the courthesy of Mikulaish, has only one change made to the original 1.15 BIOS, as described above. The rest is identical, including RAM timings. Today I flashed my homemade Voodoo 4 4800 64Mb with this release and I have done the exact same testing work as previous, to be able to compare the results with those I got yesterday.
Here are the numbers:

Home-made Voodoo 4 4800 64 Mb @ AGP 4x :
No FSAA : 1578 3D marks

2x FSAA : 804 3D marks

Post by gdonovan on 23.04.06 at 04:24:18
It is working- While testing at 800 x 600 x 32 bit color (the highest my current test LCD will go) there is a 200 point spread when the extra ram is activated.

32 mb = 2300
64 mb = 2500

<numbers averaged>

Test system is KT-266 with 1800+ 256 mb and Win98

Post by gdonovan on 23.04.06 at 04:48:10






After comparing the new BIOS and the old one with a hex editor the only change is the bit for number of SDRAM chipsets.

I wonder why the card was flashed so?

It was noticed while running 2001SE there was some  minor texture flashing the was no longer present with the extra ram activated.

Post by gamma742 on 23.04.06 at 18:37:56
Functionally, is there any difference between a "true" 4800 and a "modded" 4500 with 64MB and the BIOS flash?

Let's keep the thread focussed people! ::)

Third - how about some 32MB / 64MB screenshots comparison. ;)

And again bios-wise TM30 could clear this up, and hardware-wise if TM30 an osckhar could compare their copper bords to see if anything is different. Anyway 3 different people (Adrian aka. Komponent, Gary and Oscar) have tested their V4 4800, and all 3 had results that show a performance increase since the extra memory is activated.

... and what a pain in the "back" was that info that a hardware mod was supposed to be required rather than a simple BIOS hack! I had to strugle with different resistors configurations on the PCB, some sugested even by Hanksemenec, some of my own ideeas with no luck. Good thing that when I became tired of changing resistors, Mikulaish thought: "Let's try with this BIOS-mod too..." (nothing to loose, right?); there are out-there a few prototypes with full out-of-the-factory 64MB RAM soldered (I know about Gdonovan, Oskhar and TM30's cards) but mine being a regular Voodoo 4 4500 designed for 32Mb might just not had the hardware capacity and compatibility to accept additional memory... (cool thing it prouved to finaly be something like a easy task).

Mikulaish is just being too modest. It was realy team work; everyone of us contributed; I consider a nonsense to call someone the mastermind behind this project or who desserves better credits for the succes; I just happened to end up as the proud owner of that jewel that is this first confirmed and prouven beyond doubt home-made Voodoo 4 4800 (realy, maybe we shouldn't even call it this way; it's only the average Voodoo 4500 that we modded...).

hehe good idea, those Geforce2 MX400's and GeForce4 MX420's have good 128Bit SDRAM :)

to be very honest I rather see a NV card get dismantled than a precious 3dfx or ATi card ;D

I do own 4.5ns EliteMt memory chips (222Mhz), but the problem is that the GPU is limiting in OC for VSA100 cards. There are two types of sillicon for the VSA100: the 220 and the 320. The 220 has a bug and is not able to reach 183Mhz (exceptions might occur). The later 320 (my 3700A has it) can be overclocked to as high as 200Mhz with 6ns Hyundai ram.

you can do a voltmod on this card, so it easily can go over 200Mhz...

True, but above 2.82V (default on my 5500) the heat will kill the chip. I'm not talking 2.9V, because that does not help too much. Maybe for one crazy experiment it would be interesting, but it doesn't really worth the effort. I know for a fact that EliteMT 4.5ns memory is supposed to reach 222Mhz, but it only reaches 220 with normal timings. I beieve that Hyundai 6ns might reach this speed as well. It could be tried on a GF wich has this memory by margining only the memory clock speed. If anyone has the resources, parts, time and patience to do it, i wish him luck!

A new 64MB-mod is done:
http://mitglied.lycos.de/gtxe/v45k_64mb_mod/Screenshot_v45k_64mb_01.png

I've used the memory from a 3D-Prophet 4500.
That are 5ns Samung chips. look here: http://www.xbitlabs.com/articles/video/display/kyro2.html

I tested the card only on a p3 850 PC -> no performance increase with 3DMark2001SE  ???

But it's possible to overclock the card up to 193MHz. Perhaps with better cooling more can be reached.

hmm I suggest that you flash the card with a Voodoo 4 4800 AGP 64MB Bios, that bios should take advantage of the extra installed ram.

well I reckon he didn't because if he did use the 4800 AGP 64MB Bios why does the DirectX program see it as a 4500 AGP with 64MB instead of a 4800 AGP with 64MB like all other people have done?

Yes, i flashed the bios: http://mitglied.lycos.de/gtxe/v45k_64mb_mod/Screenshot_v45k_64mb_02.png

Hell-yes! "The best of both worlds": more and faster RAM too. This should be the ideal combination, 64Mb 5ns memory per VSA100. I would love to see some pictures with the modded Voodoo4!
If tested with FSAA 2x the Voodoo4 with 64Mb RAM should show a important performance gain over the regular 32Mb one; that is anyway the clear result that I got with the Voodoo4 that I modded myself.

all 8 chips from the kyro2 are now on the voodoo  8)

I'll try "Codename: PANZERS - Phase Two"-Demo. But i must download it first.

Edit:
SFFT41-Driver was necessary for the Multiplayer-Demo:
with 64MB BIOS: http://mitglied.lycos.de/gtxe/v45k_64mb_mod/Screenshot_v45k_64mb_03.jpg
with 32MB BIOS: http://mitglied.lycos.de/gtxe/v45k_64mb_mod/Screenshot_v45k_64mb_04.jpg
so I think the momory is working correct.

Nice job gtxe !

anyway, did you try to change the orignial cooling ?
by using a god thermal paste ( like AS5 ), you sould be able to overclock the card up to 200 MHz.
It's only the VSA now witch  don't go further ...

Question: The evilking voodoo4 models are very bad for overclocking. Mines show already artifacts at 170MHz. Any hint ?

nice one there mate. hmm that screen capture key in't supported with the 3dfx tools for 98SE, the one I'm using now is from AmigaMerlin 2.9 for 98SE combined with  3dfx Voodoo4/5 V1.04.00 aka the latest Official 3dfx WHQL driver.

I used the AmigaMerlin 3dfx tools because it has much more usable settings for the 5000 AGP to make use of :) still no Screen Capture key within it, that would be a nice fix for a newer 3dfx Tools control panel for 98SE people.

I don't want to continue the v4-64MB-200MHz-mod. It was just for testing.
v5-128MB-200MHz-mod would be interesting now. But it's difficult (almost impossible) to get the right memory chips. Look at this topic: Regarding faster memory

so to do this it is only need to get 4 same type of ram then solder them on it and load new bios?
my V4 got toshibas F54044 mem
whoah I might do that for my V4, but it's my only one  :-/ so I doub could i risk it
does anybody know how to vmod V4?? Iwas thinking to do full scale modding for it ram, vmod, new cooling (if I only find suitable heatpipecooler ;) ) what else??
and V4 supports agp1.5v 4x speed so Ican use my asrock 775dual-vsta to build 3dfx gaming rig

here the KyroII with 32MB 6ns memory  ::) (done just for training). The card dosn't work anymore.

Guys,

I have a KyroII with 5ns ram, does that mean that theoretically I could fit my voodoo 5 with this ram and have 64MB of 200Mhz ram on there??

If it has 8 chips and your VSA-100 chips can run at those speeds, then yes.

Post by ultima on 15.09.08 at 12:53:04
well,

I checked and it has 8 chips with the following print:

SAMSUNG        118
K4S643232E-TC50

and I did already have my 5500 clocked at 183Mhz before, so ......one can only hope.

Have to check with someone if they can do the soldering for me, as I have neither the equipment not the experience to undertake such a thing.

Would be interesting to run benchmarks that with 32MB would drag down the card (e.g. Aquamark 1 @ 24MB Textures with 2x FSAA).

The difference between 32 and 64MB should be dramatic there.

actually,there are some test results available (v4 with 32mb vs v4 with 64mb),in case someone is interested.in certain situation,the speed boost is as high as 285% ;D

one of the cz guys has both v4 with 32mb and v4 with 64mb..

What other video cards have same type memory that V4 use, someone said that he took memory from Kyro.
so would like GF 2MX has V4 compatible memory

Some Geforce2MX cards have compatible memory, for example a special V7100Pro from Asus.
The card has to look like this :

A new 64Mb Voodoo4 AGP has been created for G1nX/RaverX. Perfect function as allways, ofcourse.

Would it also be possible for you to resurrect and dragonize cards with dead ram?
