Very cool - I've yet to see one of those Siemens cases that doesn't look awesome. Is the fan "thing" over the expansion cards part of that, or is it a separate part (and if so, where can I get one? 😀).

well not native, but universal AGP cards do exist +1. GeForce 2/3/4/FX fit into this. Some of the older Radeon 7/8/9 cards as well. There's also "universal AGP slots" (like on Intel i815) which are meant to work with both 3.3V and 1.5V (they won't support .8V/AGP 8x but who cares about that). : …

Could the problem be related with AGP aperture size? Maybe; what's it set at? If I remember right setting it >128MB and <32MB is usually a bad idea for most systems/AGP cards - 64 or 128M should be good though. Also, any IRQ conflicts with the 6800 + anything else? Totally out there idea: have you …

For a minute there I thought you mean "original Radeon" with "7xxx" but then remembered: they have released "Radeon 7000 series" twice. Once in the early 2000s as a DX7 card, and once again a few years ago as a DX11 card. :lol: I'm kind of tempted to setup and do some comparisons with NV30 and NV38 …

Well that's the thing - Chrome on my XP rig has Ghostery and Adblock installed so it's VERY speedy even on 1GB of ram. On the other hand, using K-Meleon or old Opera on My Athlon XP 2600+ is a pain in the ass on some pages since I can't find compatible add / script blocker for these browsers. Can …

Is this via VGA or DVI? (Does the card even have DVI? If via VGA try DVI if available, or TV out if available) Have you tried another cable between the card and monitor? Old GeForce cards were not paragons of video output quality - this may just be that, or there may be something wrong with the …

@obobskivich; Time varied considerably, as most of it was taken up with short low-res animations I often rendered at VCD resolutions to save time. This would take several hours (5 or more) to complete a 3 minute video. I remember it was hard to make it work at all but don't remember much of what I …

Oh I see where you're coming from with the 16 textures per pass aspect. Yeah that is a Direct3D 9 spec IIRC so all compliant GPUs have that capability. When I say 8x0, I am referring to the 8 texture/stencil/shader operations per clock aspect. It was a Beyond3D thing I think. Yes 16 tex/pass is a …

DVD authoring on a 486? I think that "wins" in terms of old/slow machines doing something modern... 🤣 How long did it take to actually render anything? I remember working on VCD/DVD projects around the same time on an Athlon and that feeling slow enough. 😊

One thing to clarify: the Jetway motherboard you linked on ebay is not Micro-ATX. I just caught that in the thread's title, that you were looking for Micro ATX. As far as "much more modern games" in Windows XP - DX9 titles will generally work with no problems on modern systems, so the upper-limit is …

OK thank you :) Yeah I read that i'd need to pinmod the CPU I think to get it to supporrt the 440BX, which is something i'd rather not go into. So my Jetway is safe then? :P Yes the Jetway should be fine, for everything you want it to do. As previously stated, the i815 doesn't support ISA. Nor does …

I'm pretty sure that 5800/5900 can not operate as 8x1. If they were operating as 8x1, their clock speed would allow them to vastly outperform 9800Pro's single texture fillrate. I think the only 8 pixel per clock mode is 8x0. And 59x0 has the stencil rate boost as well and I think that may only be …

I don't' have a motherboard suggestion, but I will say I doubt you need a DVD decoder card, and it may actually hinder the system to install one. Back around '01 I had a 2GHz P4 (which will be surprisingly similar to your P3 in terms of performance), and it had no problems running DVDs all by itself …

Interesting. Thanks for doing this - like you, I've seen a lot of speculation about "short stroking" drives, but not a lot of tests that show things like this. Looks like the break point is around 1/4, where you're ultimately up against the rotational latency. It would be interesting to see if that …

I tried to classify these chips awhile back and came up with this: 5200/5500 - 2x2 5600/5700 - 4x1 5800/59x0 - 4x2/8x0 59x0 - 16x0 with stencil pass? AFAIK (based on everything I've read on NV3x) the 5800/5900 are all "8 pipe" variations that can operate as 4x2, 8x1, or 16x0. The 5200-5700 series …

Why not drill mounting holes on the heatsink? That should be an aluminium heatsink so any small drill will do the job. Get a couple os screws for a few cents and call it a day! My guess is the card itself probably doesn't have mount points - if I remember correctly my MX 200 was like that as well ( …

790i also supports 1600mhz FSB, but every Chipset I've ran since about 2004 has PCI and PCIe locked permantaly at 33/100 so no risk about the bus being overspeed. Also even the 965p will support 1600mhz FSB, most of us ran our Q6600's on the 965P chipset just fine at 3600mhz. D'oh! Forgot about …

With the FX series I don't think they had the same ability to disable internal components. They just varied clock speed. Though also with the FX chips what would one disable? There's not much parallelism in even NV35/38! If you halved a 5950 it'd be something like a 5200. The 6800XT would probably …
