Hi j^aws, those are really good news, but still i'm a bit afraid as this is a somewhat different variant of the nvidia 6800 cards. As you can see it is a dual molex card but it isn't (at least in the bios) a 6800 ultra card. Not sure if this would even be the same pcb as the 6800 ultra, but do you …

Thanks for the Alien Trilogy info, I have not tested yet. May "VESAFIX" or "6bitDAC" tools can help on VBE 2.0 and later cards. I will test Alien Trilogy later. No probs. I do recall trying the "Vesafix" and "6bitDAC" on some of the cards that faied, but these tests didn't make any difference. …

I almost dare to know what most would awnser but i'll do it anyway: Would sawing a "new" notch on this Geforce 6800 (dual molex) Asus V9999 in order to fit it in AGP 3.3V kill it when i turn the pc on? http://www.techpowerup.com/gpudb/images/b1796.jpg I know this question sounds pretty dumb but i …

ISA video cards also slow things down. However they don't slow down the CPU and can still cause issues with some games, so use these results with caution. Yep, did consider testing an ISA VGA card, but I don't have one at hand to test. I still have a S7 board for backup anyway. Your results match …

It could be an alternative signal path for TOSLink instead of SPDIF - Creative just left the option there and went with the SPDIF bracket...?

Great work bjt! I'll try to finish the rest of the tests with v.1.3 over the weekend. BTW, Mau1wurf1977, I was getting scores around 13-14 using 3Dbench with an overclocked Tualatin Celeron (L1 off). EDIT: L1 on, didn't register anything.

Great, looks like the ISA clone cards are working well now. Thanks for testing these, they will make a good addition to the compatibility list.Couple of questions: - Do any of these cards support IRQ 2/9? No probs. I wasn't paying attention, but are you asking whether there was a "2", "9" or a …

I'll explain. From a BIOS perspective L1 is CPU cache, L2 is mainboard cache. I don't recommend Slot 1 machines because once you turn off L1 cache the machine is super slow. On Socket 7 you can leave L2 on and get a 486DX to 486DX2 depending on what CPU you have. Turn L2 off as well and you have a …

What board do you have that comes with mainboard cache? Well, my BX mobos don't have mainboard cache, but my Socket 7, Abit AX5 does (512K, IIRC). I'm not sure why mainboard cache would benefit my setup? BTW, I just tried Test Drive 3, and that works on my fast BX mobo too, with L1/ L2 caches …

Because it is lacking mainboard cache, Slot 1 machines are either very fast or super slow. So you have this huge performance gap that you can't reach. Check out my video here: http://youtu.be/gzxnB2CD6aw?t=21m33s I put the start showing what performance levels you can hit with various CPUs. On your …

Slot 1 systems come to a crawl when L1 cache is turned off. It doesn't surprise me that music slows down. Not a fault of SoftMPU. Go with a socket 7 build instead :) The music's fine (MIDI). The graphics, and sound effects, slow down accordingly with caches disabled. However, everything's fine with …

Yep, that's strange. I think we can rule out a CPU speed or sound card issue. Just to check, are you running under pure DOS, not a Win98 dos box? Yep, running from pure DOS. Just tested a couple more cards: SB16 (CT1750) and OPTI x924 (Crystal 4231) - identical tests as above and identical results. …

As Hal already wrote, NMI is just needed for the SBOS emulation software. For native mode NMI is not required. So if your GUS does not work correctly in native mode (I usually check with various trackers) then NMI is not the cause. I haven't installed any trackers yet. For quick testing, I just use …

I tried everything mentioned in this thread before changing mobos: - Tried varying 8bit and 16bit i/o timings, but that didn't make any difference. I usually stick with 4:4 in the BIOS, and that currently works fine on the currrent mobo. - Tried various CAS timings - didn't make any difference. …
