The table of PnP codes of YMF chips Links Introduction YMF7x4 (724, 744, 754) are the only common PCI sound cards with genuine OPL3 chip. With SB-Link they have good SB Pro compatibility in DOS.

When have good codec they produce not bad sound via LineOut. Also these cards have 3D sound in Win9x games and good GM. This makes YMF7x4 cards interesting for DOS-Win9x retrogaming machines as universal solution. Also with these cards you may get quality SB Pro sounding on machines without ISA slots, like Pentium 4. And real OPL3 FM with DOSBox paththrough in WinXP on later CPUs. This guide is initially based on 'YMF7x4 FAQ' by Andrey Revvo, site by N.Shima & Vivas, Vogons and other sources. For some links you'll need to use archive.org 1.

Basic features of YMF7x4 cards YMF7x4 - PCI sound cards, based on Yamaha chips YMF724, 740, 744, 754. YMF cards, made by brands, are of close class to SB Live and Vortex. ZanQuance wrote:Aureal Vortex2 cards support more than 16 DS3D channels, they can handle 80 DS3D The principle limit is 76, but practically this is limited by drivers.

In the beginning, when most review were done, the drivers allowed only streams. Later 2048 driver, according to, allowed on MX300 same 16 hardware DS3D streams. Previous driver 2041 allowed 32 hardware DS3D streams, but seems this appeared not optimum and 16 were returned. Only faster SQ2500 was allowed to keep 32 streams, but the classic Vortex 2 is the version by Diamond. Similar situation was on YMF, when some 20xx driver allowed 32 streams, but newer version switched back to 16 (VxD initially had 8 streams, I still need to find info about 1040 driver). I may speculate that this is related to chips performance, drivers optimizations and that games used not only DS3D, but also EAX or A3D; so to allow all 76 streams they'd need to make special driver for games which use DS3D only. So that 76 hardware DS3D streams of Vortex 2 are only on a paper.

There is no need to speculate as I have the original Aureal documentation on hand and have been using it extensively to write new drivers for the cards. I have a very good understanding of the chips now (I'm saving most the information for the new Website launch). The SQ2500 AU8830B0 is not actually faster in audio channels than the MX300's AU8830A2 in which it would allow more audio channels to be piped through. The drivers always support all 96 audio streams but there were bugs that misreported what was available, a few channels are also typically reserved for recording. The 80 DS3D channels are derived from the internal hardware Sample Rate Converters count, 64 in the WT block and 16 in the SRC block itself. 76 were stated as it reserves 4 SRC channels for input/recording sources. The 12% performance gained in the AU8830B0 revision from the AU8830A2 is related to the Vortex audio Data Bus (VDB), it appears they corrected some VDB stalls that occur from various configurations when using the WT cell for directsound streams (reflections).

The AU8830 has always had 96 DMA channels and 4 sub buffers for each available. There are 64 dedicated channels feeding the WT block and 32 more channels that connect directly to the VDB bus. Each are dynamically routed so whatever WT voices aren't being used for midi can be used for DirectSound 2D/3D playback. DS3D should report whatever the drivers aren't reserving, so most of the time it's 92 available DS channels and 76 DS3D. I don't see the channel bug using the 2041 drivers, but the 2048 drivers had an issue noted in the readme that only 16 DS3D channels are reported when A3DVerb is enabled, and this was fixed in the 2050 drivers. So this isn't a limitation of the card, just driver bugs.

I also now know what causes the Stereo flipping and pop/crackling bugs, it's incorrect VDB chain routing and correlation settings in the mixer and Sample Rate Converter aggravated by DMA misses. They tried to multiplex the audio streams and that's why they flip sometimes or are completely reversed from the get go.

The AU8820 is what was limited to 8 3D audio channels and these were rendered in software, but it supported 32 for Direct Sound. It should be noted that the MX300 is just as powerful as the SQ2500 and there should not be any preference to have the AU8830B0 over the AU8830A2 just for the newer chip (although I understand the feeling of newer is better).

I think you will be using it more than you plan. And perhaps recommend it in some of the Dos/Win hybrids that you are doing on Youtube. You will be surprised that something this flimsy looking, can deliver that much. Personally, I have no Vortex of any kind.

Nor have had one ever. On the YMF-724. I am a warm speaker for this card, compared to SB-Live and other PCI cards. And still acknowledge that in some cases, an Vortex is actually a way better choice.

Depends on what the need's are. SB-Live are way inferior by design if you ask me. It's not a true Stereo card, and you really want to have an stereo card when doing some pre 99/00 build for gaming all the old games. It has 'real instruments' sound cabability (wavetable/midi/whatever you want to name and call it), just as well as the Live has.

The thing that really sets it apart from the Live. Is that the YMF-724 has OPL core build into the XG chip. Wavetable/midi combined with OPL3-Core in one package, SB-Link and in some cases XMS cabable setup in pure MS-Dos.

YMF-724 is one of the top 3 retro-cards when dealing with PCI soundcards. Can't go wrong on this card as a collection item or in multi soundcard build's.

Remember that it only makes any difference for systems using the VIA VT82C686A/B southbridge. I had to change the DMA mode to DDMA in the SETDUPDS utility and set DMA to 0 for get things going. Amazing thank you!! Its a Jetway 993AN with a Via Apollo 133 Pro and a Via 82C596B so I am praying it will work, all other attempts have failed Worse part is the modern case covers the ISA slot els I would have just fitted a SB16 and called it a day.

Examples of potentially problematic games to try different methods of DOS support: Commander Keen 6, Descent 1 & 2, Doom, Duke Nukem 3D, Dune, Epic Pinball, Jill of the Jungle, Larry I VGA, Laura Bow: Dagger of Amon Ra, Mega Man X, Police Quest 3, Prince of Persia, Quarantine, Sam & Max - Hit The Road, Space Quest I VGA, Wing Commander 2. I recall testing most of those games in the past, and they worked fine in pure DOS 6.22 with SB-Link. I'll check those out when I get sometime and post the results in my compatibility thread: Oldbie Posts: 645 Joined: 2013-2-02 @ 19:39 Location: UK.

Still a no go for me, if I use the modified one it doesnt detect the sound card at all. The default one detects the sound card when I select D-DMA, I have to select DMA 0, I set the IRQ to either 5 or 7 when I run the test, 8-bit, 16-bit and FM works 100%, games like Wolfenstein 3d Flawless, Doom, duke nukem etc. Says there is a DMA conflict and just refuses to work at all.

But thank you for uploading, maybe it will help some one els? Try my modified SETUPDS utility with the DSDMA TSR with the drivers provided on the Yamaha website, I think it actually disables DDMA support for the VIA 82C596B as I exchange it's PCI ID with the one that belongs to the VIA VT82C686A/B. Also use the YMFIRQ utility to change the PCI IRQ to the same as the SB IRQ. You can find the YMFIRQ utility in the driver package provided here: Just remember to load YMFIRQ after the SETUPDS utility and DSDMA TSR. Maybe DSDMA is the way to go on your board instead on DDMA.

Stretch wrote:is it better for me to set Dosbox-Daum OPL and mixer to 48000 since my YMF-744 has a different clock than the YMF-724? Or do I leave the OPL rate at 49716? Param oplrate= relates only to OPL emulation.

When you have oplmode=hardware, then oplrate= has no effect. Now about mixer. To set rate=49716 has sense only when you are using OPL emulation. In case of oplmode=hardware, the param rate= relates only to PCM in DOS games, wich is either aliquot to 11025 or below with ugly quality. Thus, it's better if the final upsampling will be aliquot to 11025, hence to use rate=44100. If your card supports 44100 without SRC.

In case it does not support this, then you'll need to test and choose between SRC to 48000 done by DOSBox (rate=48000) or by your sound card (rate=44100). Practically PCM sound in DOS games is not good, so you may don't notice the difference. When you wish to use OPL emulation with oplrate=49716, then you need to try and choose between SRC done by DOSBox (rate=48000) or by your sound card (rate=49716). If for some games you'll think more erratic OPL play is lesser evil than SRC artifacts, then you are using oplrate=48000 and hence should be used rate=48000.

Also some cards have mediocre codecs what makes the situation worse. YMF730 used on that two cards is probably than STAC9704. YMF7x4 cards, when were new, costed $20-30 - to wait from them same as from Santa Cruz which costed $100 is excessively. Also there was used 44.1 kHz, while SRC may be improved by settings or other version of drivers. The example there is Hoontech SoundTrack Digital XG YMF754.

I'll ask the seller anyway, but still would like to know if the STAC9700-equipped ones are worth buying. Besides codec, it's important is that card branded or from nameless Chinese basement. So it's good to try identify the card by the pictures. Some cards look very similar to branded ones - these should be good ones, just sold by other brand or original OEM with some cost-cut.

The example are Diamond MX300 and Aureal SQ2200 - the later just has no the chip for one of connectors. Or Genius 128XG and A301-G50 (nonbranded made by Labway) - the only difference seems to be in additional capacitor on retail 128XG. Also is the card extremely cut-costed bare textolite or has elements like capacitors in a good quantity. Is it in well condition or with damages and rusted.

Some such guesses and card's comparisions you may do without special knowledge of electronics (I have no it). YMF7x4 are not rare cards.

If there is no good model - wait a little or better dig what is selling. The price of $10-20 or lower is common. If the prices are higher - look for other selling place or more adequate seller. For common cards (YMF are such) I dealed only with local markets, though. @Stretch At least the results you linked above say that the noise levels are 'good'. Also, could you explain/give example of how 'poor IMD' ('intermodulation distortion' if I'm not mistaken) sounds like? Anyways, considering it's not exactly a quality SB-pro compatible card I'm replacing (ISA Aztech SG NX something), I think I wouldn't complain to be honest.

I do have the MX300 though. But it's the XG I'm looking for, it should satisfy me until I get one of the better MU-EX modules. I found some games really do sound better on XG than on Roland SC/GS. @Tertz OK, thanks for the advice. I found some very cheap YMF724F-V cards (all off-brand it seems) at about $4 per card local, so I'll give it a shoot anyway. There's also a YMF744B-R but it doesn't have the PC/PCI connector.

I have an ASUS P2B with SB-Link which I'd like to try. I'll post some photos after I received the card.
