Yes, the capacitors next to the toroid inductors are part of the CPU voltage regulator output filtering. You can get into the weeds of component specifications but generally speaking, if a capacitor is 1800 uF and 6.3V it will probably be better than what's in there now. Low ESR and high ripple …

https://theretroweb.com/motherboards/s/atandt,-inc.-at-and-t,-inc.-globalyst-550-c Has a lot of similarities with the AT&T Globalyst 550 including the security/speaker/LED headers near the cache slot. That board also has a J53V jumper for CPU type selection in its jumpers manual. I would think this …

Could always run lspci -vvv on your system and look for a "PCI-X Bridge Device" entry in the capabilities list of the host PCI bridge(s). No entry, no PCI-X. Personally, I don't think any Pentium 3 system that isn't a Compaq ProLiant DL760 Generation 1 has them. "PCI-X System Architecture" from …

The 1MB cache stick works great, even with the fastest timings at 40 Mhz. Doom changes from 1276 realtics to 1239 with the larger stick, so there is a measurable, but not exactly noticeable improvement over 256KB. Quake changes from 16.8 to 17.8 FPS. That's noticeable, and a 6% increase is about …

Dark smearing across the screen: Saw this on a GeForce 256 and have heard from a few other people about their GF256s doing this as well. I'm not sure about the root cause, but I think it's DAC degradation. I experimented with fixing it by replacing the VGA connector and doing RGB signal buffering …

Here's a fun one: The Matrox Parhelia with the 64-bit PCI connector isn't PCI-X. We can tell this a few ways: 1. The big chip on the back is a PLX PCI6154, which is a plain old 66MHz 64-bit PCI bridge 2. PCI-X cards have a signal called "PCIXCAP" on pin B38 which is tested by the source bridge at …

I haven't had any issues with my Tiger MPX system (also dual 2800+s, Radeon 9700 Pro.) I'd worry more about 5V rails if the board didn't use 12V for CPU power.

Have you done any pinching on the memory or graphics chips while it's running to see if the lines change? Can be a decent indication of a broken solder joint that needs touching up.
