Here's the performance matrix from the magazine I was talking about (PC Games), I thought it's pretty interesting. Their definition of "optimal gameplay" (green) is around 30 FPS, I believe. https://archive.org/details/pcgames200305/PC-Games%202003-05/page/n115/mode/2up They also mention that …

Thank you for the explanation. I shouldn't have said "porting" the library, I meant just taking the functions from it that the FSB tools use to write into the CPU and clock generator registers. It would have been useful as a starting point because I have never done that before. I remember looking at …

Yes, I've had the same lockup when I tried to underclock the bus in Windows. Interesting that it persists with a reboot, I think I haven't tried that. I was wondering if there's a DOS tool that can underclock the CPU, maybe this way it wouldn't lock up. There's an open source library called WinRing0 …

I think you're just CPU limited. There was a big FPS drop when you lowered the CPU speed from 1800 to 900 MHz, and the photo of the two laptops shows 1600 MHz (33 FPS) vs. 1800 MHz (37 FPS). This is not far off from an Athlon XP system with 2000 MHz that reaches 35 FPS. And the newer graphics …

In the bios there should be an option to set hypertransport speed. On S939 Athlon64 it's 1000mhz by default, and is usually set by a combination of base clock 200 and multiplier 5. The cpu speed can not be lower than the hypertransport speed. So to run the cpu at 800mhz you need to find the bios …

I had the same issue, I only get 15 FPS on my Duron 700 machine no matter what video card. Turns out that this game is quite CPU heavy, the box definitely lies by saying 500 MHz or better. I dug out two magazine reviews from the time and their "performance report" boxes show that a 1400 MHz CPU is …

Also make sure that your video card is not too new. Your board might not have support for PCI 2.2 cards yet (most cards from the late 90s onwards, including the Geforce).

That's a very big heatsink, I wouldn't worry too much. You also have that big CPU cooler near it. Just let it run with the K6-2 and keep your finger on the heatsink, it's only a problem if it gets so hot that you can barely touch it. Also remember that most boards have two or more of these. I have a …

Depending on the type, you can also screw a metal heatsink on …

My favorite tool for this is a brass wire brush. It's very effective against rust, but soft enough so that it won't scratch the steel. But if the shield is made of aluminum, you might have to be more careful. Submerge it in any type of acid (vinegar, citric acid or bathroom cleaner) and after some …

I'm trying to get a more authentic Windows 98 experience on my Athlon 64 machine. I was hoping to underclock it to 500 MHz, but the lowest I could go was 1000 MHz (200 MHz system clock, 5x multiplier). The board's lowest multiplier is 4x, but that gives me a black screen at boot. I tried to lower …

It seems that there are some conflicting opinions out there about the VGA signal quality of this card. Chip != card. Just as with S3, and unlike say 3dfx (at least from V3 onward) and ATi who made their own cards, the early nVidia-based cards were made by a multitude of different card vendors. Some …

That's good to know, thanks! It's hard to find any information on this except for that PCI 2.2 specification sheet. Edit: I've just tried the cards in another old board (FIC 486-VIP-IO, Socket 3). This one specifically mentions in the manual that it is PCI 2.0, and the cards also didn't work there. …

Thank you, this could be it. Is this a general problem with AT motherboards? As far as I understand, AT power supplies do not have a 3.3V rail at all. So the only solution would be to build a device that generates 3.3V from 5 or 12V and then solder that to the board or card? Since I have no …

I've just had a look at the PCI pin specifications: https://pinouts.ru/Slots/PCI.shtml On the old card that works (S3 Virge), the +3.3V pin (number 25) leads nowhere, but on the Riva, it goes into the graphics chip.
