Hello all,

Well I have some good news for you 3dfx Voodoo3 3500 TV AGP 16MB users/owners, as that I did some useful research last night, it's that some time ago I bought a M1-DA to VGA convertor cable and thought to put this thing to use, the VGA connector is male so to solve that I used a VGA/SVGA DB15 D-SUB 15 Pin 3 Rows Female To Female Mini Gender Changer Adapter on it's male 15 pin D-Sub connector, that way I could connect the CRT to it and presto this worked!

The image quality is fine to around 1600x1200, I have 1024x768x32 and yea no issues at all, bottom line is that is much less strain on the 3dfx Voodoo3 3500 TV AGP's M1-DA connector, this is my goal so I wont have to use that horrible blue 3dfx IO Pod anymore 😎

So I bought this M1-DA to Male VGA Convertor cable on ebay in China for around 23 Euros incl shipping from China to Netherlands, it may not seem great, but it's much better than even I had expected, it fits very easily, no need to bend out the shielding of the 40+5 pinned M1-DA connector on the cable, it fits easily.

But hey it's a solution right! So with this you won't have to overpay yourselves for a Voodoo3 3500C + TV-Out Compaq board, so I thought to at least test this and see what it does and post it here as it does actually work!

Here the ebay seller I got mine from:
https://www.ebay.ie/itm/387155543843

Just make sure you add a VGA/SVGA DB15 D-SUB 15 Pin 3 Rows Female To Female Mini Gender Changer Adapter between this and your monitor, aka one of these:
https://www.ebay.ie/itm/133567891402

With that you're good as gold, it's a fantastic solution for us Voodoo3500 TV AGP users alike

Also you don't need to use the extra USB connector that comes with it, just the heads up for those wondering.

Hereby saving everyone money in the end, here how I connected the M1-DA to VGA Convertor cable to the 3dfx Voodoo 3 3500 TV AGP 16MB Rev.A 3199 and the Compaq S710 17" Blackshade CRT

Here the insides of this beauty:

Here the M1-DA to VGA convertor cable:

And here the VGA/SVGA DB15 D-SUB 15 Pin 3 Rows Female To Female Mini Gender Changer Adapter which you do need to make it work:

All working as it should do and just letting other Voodoo 3 3500 TV AGP owners know that this methods works very well and can be seen as a low cost solution as well and with this ideal solution you won't have to use this horrid large and heavy blue 3dfx IO Pod anymore:

For every problem there is always a solution, that is the how we think at x-3dfx and if I find out something helpful I'd gladly share it.
Happy weekend everyone 😎

Here some pics I made, after searching for this card for more than 10 years, all worth the patience in the end, I added my 1971 Lufthansa B747-230B the D-ABYD named: "Baden-Württemberg" with the R6 card I bought from my friend from Voodoo Alert Forums, Germany, to fit that scene, this also being the first Radeon AGP with 64MB 128Bi t DDR, I thought to match it with Lufthansa's first B747-200B sporting the Lufthansa Sunrise Delivery Livery from 1970 and my ATi hat, even tho I will try to find a better one, this one will just have to do for now:

in May I will try and give this system a 3dfx Voodoo3 3000 PCI 16MB SDRAM, if I can find one for a decent deal, Voodoo Alert will come to my aid maybe, I'll see what I can do with that, as for the CPU the Athlon 700 is a bit on the slow side for that R6, so an Athlon 850 or 900Mhz Thunderbird Slot A CPU will be what I'll be seeking as well, yea just gotta find the right parts to fine tune this system correctly, all within time of course.

Hello everyone, sorry for not being that active, I had a rough time with the passing of a close family member, it did take me some time to get back in to it again.
But finally I was able to upgrade the Slot A build to something far more proper, I added the following parts just to perfect the system and make it more optimized for it's timeline of Mid 2000.

AMD K7 Athlon Thunderbird 900Mhz for Slot A
2x Noctua NF-A6x15 FLX 60x60x15mm fans

So here the pics of this beauty that is finally completed:

Here the CPU with the two Noctua fans mounted on it's brass colored heatsink, screws all are different I used what I ahd laying around, it's gives cool Makeshift look rofl

Here the two graphics cards:

ATi Radeon AGP 64MB 128Bit DDR Rev.C1 0111
3dfx Voodoo 3 3000 PCI 16MB 128Bit SDR Rev.A 4599 with 5.5ns SK Hynix SDRAM

Here I set the CPU voltage from 1.75 volts to1.60 volts and ran Prime95 Torture test for 9 hours and 7 minutes, all tests were passed and no errors were reported:

Here a test out of curiosity at 1.55 Volts, at first I was like haha! this won't last long, but surprisingly the system ran Prime95 Torture Test for 2 hours and 6 minutes, passing all tests and also no reported errors, this did impress me that my K7 TB 900 has a very high quality die:

But when I wanted to reboot, just because why not, the system hanged and the monitor went black, so after turning off the system and discharging the PSU and then turning it on and going back to the Bios I set the CPU back to 1.60v and all is great again, I played Star Wars Dark Forces II Jedi Knight for a good 4 hours flat with the ATi Radeon AGP 64MB 128Bit DDR ViVo Retail @ 1024x768x32 + FSAA x4 & AF x16 without any issues a nice heavy test but it ran the game like no tomorrow.

So yea this did prove me that with the CPU voltage set to 1.60volts that the system is stable under all workloads, this will make the CPU less hot under long term work loads and this also helps put less strain on the +5 Volt Rail of the Power Supply Unit, well as how I was informed.
This hobby does help my mental state a lot, it helps me focus on positive things more 😎

Hey all,

It's tie for something new and different , well from my end anyway, as I never was able to experience the Pentium 4 done right, the Northwood series of CPU's were by far the ebst i heard and read about, there were three different Northwoods that are these:

Northwood A 512KB L2 & 400Mhz FSB No Extreme Editions for this one
Northwood B 512KB L2 & 533Mhz FSB No Extreme Editions for this one
Northwood C 512KB L2 & 800Mhz FSB Extreme Editions came @ 3.2Ghz & 2.4Ghz with 512KB L2 and 2MB L3

So the one I went with was the last generation of Northwood which is the Northwood C, most of the needed items I already have, this is a build log for this new build and yes I will run my V5 PCI Mac in this build as well, should give that card the CPU speed it needs.

As for the mainboard Richard from x-3dfx helped me finding the one of the best OC boards of all time, which is the following:
ASUS P4C800 Rev 1.04 0327

Which was from this auction:
https://www.ebay.ie/itm/404807128219
There are Rev 2.00's, that I am very aware of, but these were too damn expensive so I went with this one, which seems to have been either well cared for or even recapped, well by the looks of it.
Even so I'd happily send this mainboard to Backfire for a Würth recap, such things can't hurt it I'd think.

Here the CPU stand alone:

Intel Pentium 4 HT Northwood C 3Ghz, 512KB L2 & 800Mhz FSB for Socket-N 478:

And here the main graphics card for this build which is powered by ATi's R350 KAHN-B VPU.

The ATI Radeon 9800 Pro (released in 2003) featured hardware F-Buffer (Fragment Stream FIFO) technology. This on-chip memory buffer allowed the GPU to execute pixel and fragment shaders of near-unlimited length without the severe performance loss traditionally caused by multi-pass rendering

Sapphire Atlantis Radeon 9800 Pro AGP 128MB 256Bit DDR Rev.C1 0411

So yea there ya have it, more to come as more parts arrive!

Yet I may need help finding me a pair of 2x 1GB Corsair XMS Platinum PC-4400, this is DDR 275Mhz DDR1 memory or say 550Mhz DDR per stick, I know it exists, but it seems to be very difficult to find.
If anyone has tips feel free to DM me of it, many thanks in regard! 😎

Today the 3dfx Voodoo4 4500 PCI 32MB arrived from Canada!
