That sounds like something else is at play. Having that many components that refuse to cooperate is very suspicious.
Have you tried a different power supply? If so, what brand and model and gold old are the ones you have tried?
Has that motherboard been recapped?
Do you have another socket 462 motherboard you can use to test?
PSU: Chieftec GPS-350FB-101A (Delta, recapped), Corsair TX850M (v1, orange)
Motherboard uses Rubycons exclusively (no Nichicon)
Tested on 7N400 Pro2, same behavior across all T-Bred chips.
That is really strange. I've never had issues like that. Makes no sense.
The dropping to a lower multiplier on some CPUs is normal behaviour.
Have you tried lower voltage on the T-Breds? Default voltage is max 1.65v. I wouldn't feel safe going over 1.85v with excellent cooling unless using sub-ambient cooling and even then that would only be for max speed runs.
You should be able to get at least a couple hundred Mhz extra at about default voltage.
Ok, looking up some more stuff since it has been so many years since I have had a regular T-Bird.
1. It sounds like the draw from the 5v rail is really high and most newer boards may have issues with powering them.
2. May / probably need heatsinks on the VRMs to keep them cool.
3. You want a PSU with 30A+ on the 5V rail. Higher than 30A is better.
4. Pushing that much amperage on 5v through the 20-pin ATX connector can be a problem and may overheat and possibly even melt the plastic on the connector - need to keep it cool. Making sure the connector has a really good connection should help somewhat.
5. Newer boards may not handle the multiplier as expected, even with the bridge unlock done.
6. Newer boards that have the 4-pin connector, have a different VRM design than those that don't. Those that don't have a much better design for 5v heavy loads. Apparently when converting those types of boards to accept power from the 12v connector, you get a much more efficient setup along with much cooler running VRMs.
Hmmmmm. Now I want to mod one of my ASUS A7N8X v2.0 boards.
