I started another build. Parts all ordered waiting to get my hands on.
So i want to build a perfect system around the Voodoo 5500 for Win98SE Gaming.
Goal is able to play all the holy 3dfx Games like Deus Ex in 3dfx Glide with 1600x1200 Resolution.
Im still not sure this will be possible at all, or better sayed on what fps..

Anyway after doing some research i choose the follow components. System will be run only Win98SE, so i dont need HT.
Feel free if you think i can add or change something.

Mainboard: Asus P4S533-E (AGP 3,3V compatible)
CPU: Intel Pentium 4 SL6PG 3,06 GHz, 533, socket 478( cooled with Scythe Mugen 2 Rev B PCGH Edition)
GPU: 3dfx Voodoo 5500 AGP 64MB 3,3V
RAM: Corsair 2x 256MB XMS CL2 ( CMX256A-3200C2 DDR400)
OS: Windows 98SE
SATA: Samsung SSD 120GB on Promise FastTrak S150 SX4 PCI (256MB)
Screen: Asus 24" L PA248QV 1920x1200 IPS 75Hz
Audio: SB Audigy 2 ZS Gold

Pictures follow soon i start with

Wth SIS chipset, any common DDR400 memory from reliable brand will do, since it will work just fine at DDR333 speed on CL2 timings.

SB Audigy 2 ZS Gold

Might as well install Aureal Vortex 2 for A3D 2.0 support in Win9x environment.

Sis 645/dx unofficially supports ddr400. With the same board i managed 192/384 i was overclocking a pentium-b/533 2.8 and 3.06. The secret sauce to a sis645/dx is to run a high multi p4-a/400fsb and try to stay before 133fsb/533. Because for some reason when you use 533 fsb that memory divider it uses tends to take a hit somewhat in bandwidth i noticed. Like it loosens up the timing/sub timings. These were my findings like with a p4-533 i managed mid 2800mb/s scores in mem. I still think the key is pentium 4-a.

thats one point i choose this corsair RAM. i read a benchmark from tomshardware where exact this ram was one of few able to run ddr400 with cl2 . It was also the fastest ram on benchs. I will see when the parts arrive.

Real nice build
The Vortex 2 will give you A3d 2.0 and but only gives you EAX 1.0 (or 2.0 if you use driver version 2.048)
For EAX 3.0 and above you'll need a Creative card but this will only give you A3D 1.0 your 2 ZS is the best choice on this side of things.
Neither card is that great and emulating the others technology.

Ends up been a case of pick your poison.
Not my list but this shows each games support

Thanks for the Info. Is it no possible to use the mx300 and the 2ZS in one system?

Today i got the Asus TFT. First tests with My Dos rig:

70Hz with IPS on Dos

Sorry if this sounds like nitpicking, but the points below are worth knowing about, IMHO. However, they may not bother you, in part or at all.

a)
70Hz input support, at least over VGA, is a given for backwards compatibility reasons, however not all monitor actually display 70Hz (frameskip) and not necessarily on all inputs (VGA vs HDMI). AFAIU, your monitor is capable of up to 75Hz ( both input and display), at least over HDMI .

b)
That monitor does not have a 4:3 mode that works for 640x400 (320x200 line doubled by VGA card), so most VGA DOS games will be stretched horizontally.

c)
Are you bothered by the fact this monitor, like practically all TFTs, samples 640x400 (320x200 line doubled by VGA card) ? An example of the effect of this can be seen in the uneven with of the lettering on Doom's HUD (bottom right).

If point a) is an issue (might not be, might not bother you if it is), an OSSC can address it.
Point c) can also be fixed by an OSSC .

Point b) is not fixable by an OSSC. An Extron RGB DVI 300 (or its HDMI version) will fix b) and c) but will force 60Hz, add a little latency and not be as sharp as an OSSC

See Re: Purchasing a 4:3 LCD for DOS/DOSBOX/MISTER/OSSC games? for more info on that monitor

Good points. Yes i will try it with an ossc. I tryed serval 4:3 TFTs but i dont like old used Panels any more. My Dell ultrasharp 2007FP dies after 2 month, ok unlucky. Than i bought new old stock HP LP2065 4:3. The panel was damaged after delivery, more unlucky.. Anyway the Panel is more for the win98se build here focus on 1600x1200. I can live with the borders than.

Further testing. I got 4:3 working with the Asus

Used hdmi source from the ossc to the framemeister , output mode DVI. Than i choose aspect ratio 4:3 on the framemeister. After that i can activate 4:3 on the Asus. But i see the 60Hz Problem darry talking about.

Cool!
I did not realize you that you have a Framemeister (well regarded but expensive piece of kit). I am not very familiar with it. Does it preserve 70Hz or does it convert to 60Hz ? Also, AFAICR, the Framemeister only outputs in YCbCr at 4:2:2 , so I wonder if there might be any noticeable image degradation due to the RGB--> YCbCr conversion and chroma subsampling .

EDIT: I see you answered my question about 70Hz. Sorry, I missed that initially . I have gone through about 5 or 6 scaler/digitizers and found only one (and likely its rebranded clones) that preserves 70Hz, but it only does so when outputting 1024x768 and only accepts 70Hz when receiving 720x400@70Hz . That unit is the Cypress CP-254 DVI to DVI scaler . It is not without its shortcomings, however . See Re: What are the best Vga to hdmi scalers or peripherals for MS-DOS games ? .

With any currently available monitor with or without any available (including discontinued ones) scaler/digitizer that I could find, the only way to preserve both 4:3 AND 70Hz in DOS games is to have a monitor with an explicit 4:3 mode . If there is any other way, I would love to hear about it .

Thats the point i got only 60HZ. Im not sure this is because the framemeister or hdmi. I also wonder how an xrgb3 perform because its more for PC Signals. It offers also 640x400 but i cant find any information about 70Hz..
About your picture quality question i have to test it, but first i want the best signal.

I did some more reading and, according to this http://junkerhq.net/xrgb/index.php?title=XRGB … 86.92_Sync_Mode , frame rate passthrough at 70Hz might work with Sync Mode set to off :

Sync Set → Sync Mode
This setting affects the output frame rate of the unit. When set to OFF, the Framemeister's output frame rate is converted to a standard NTSC output rate, regardless of the input frame rate. When set to AUTO the output frame rate more closely matches the input frame rate, even if this deviates from the official HDMI timings. On other video processors, this is called a framerate lock or output frame lock.

Ideally, it is best to leave this setting on AUTO. When input and output refresh rates are mismatched, picture stutter or judder can occur. However, many old games systems (particularly PAL systems that have been modded for 60hz output) have refresh rates that are too out of spec for some TV's to cope with. In this case you may need to set sync mode to OFF and just put up with the picture judder. For more information, see this page.

There's is currently a bug which doesn't always fully disable the sync lock even when this setting is set to OFF. This can cause problems with capture cards like the Blackmagic range.
