I'm building a Win98 retro project of my own, using a PCI-e motherboard along with ATI Radeon X850 XT PE. For comparison reference, I used this video: https://youtu.be/abYeIixYrbk?si=zwENhTIkGUDwhTDQ&t=770. But for some reason there's quite a gap between stats in that video vs. what I'm getting. The …

Hi P5PKL-AM/PS has the pci bus behind a pci-e to pci bridge. Maybe legacy ports aren't propagated. SB support on wdm drivers is pure sw, vxd drivers use acceleration from hw that need access to legacy ports. Wdm drivers don't include fm music emulation, you can try to select general midi music. …

Hi again! I'm a beginner in all this so apologies if this is a noob question. I have two motherboards: ASRock 775i65G and Asus P5PKL-AM/PS. And a sound card: Labway A301-G50 Yamaha XG YMF724F-V. For both motherboards, I did a fresh install of Win98 SE. Immediately after that I installed the sound …

For that specific PC a modern budget Bronze rated PSU from a "popular" known brand that's at least 300-350watts would be fine. That makes sense. I was not comfortable suggesting anything specific, as OP seems to be based in India and I am not familiar with what options (and their quality) are …

There a few points of importance here a) the power connector on the video card is a 6 Pin PCI Express (PCIe) Power Cable Connector and ONLY uses 12V. b) the first (non working) power supply is rated at 15A on the 12V rail whereas the second ("working") on is rated at 16A, which makes it …

Never heard of Zebronics before. How many SATA and Molex are on each of the two NON-mobo leads ? What motherboard are you using ? Just curious SSD do not require much amps....so assuming the PSU can deliver even 2/3 of what is on the label you should be ok unless running some Athlon cpu that need …

The good news is that either is actually an Aureal chip that has been re-marked as a C4624 for some odd (to me) reason OR some company cloned a Vortex chip AND marked it wrong . The first scenario is most likely. If we add all this together, it seems very likely that your card is cheaply designed …

That is not a Vortex 2 (aka Aureal AU8830 based card ), unless the main chip is remarked . EDIT : Your card's PCB looks a lot like the one in this thread . https://www.vogons.org/viewtopic.php?f=62&t=73820 Except yours has Vortex Intex branding on PCB and obviously the markings on the main chip . …

Another bit of info that hopefully helps with debugging - there are 4 slots in the sound card - "in", "front", "back", "mic". Switching between front and back doesn't eliminate humming - just that the volume output of the "back" slot is higher. For both front and back slots (the only difference …

Quick update - I just tested the two sound cards (the working one - CS4281 and the problematic one - vortex 2) on a different motherboard (P5KPL-AM/PS). Again, clear audio with CS4281 and still humming sound with vortex 2. Seems pretty definitive now that it's a sound card issue. Is there any way to …

That sounds like it might be a ground loop, except for the fact that doing nothing more than swapping in the old sound card fixes it. As a test, can you plug in headphones directly to the sound card instead of the speakers ( which I presume are AC mains powered )? Maybe the issue is linked to an …

I have an Aureal vortex 2 sound card and a 775i65g motherboard. I have another sound card (Cirrus Logic CS4281) that works just fine with that motherboard.
