Do you have a multimeter? If so I'd check voltages. If you have one and want more detail, I can go into it. Go ahead, as I plan on grabbing one when I'll have the occasion! You can put the black probe on any convenient ground point, like up against the case of the PSU or plugged into the black wire …

Booting without the CPU, expecting beeps but nothing The CPU executes code from the BIOS, which is what contains the programming for it to beep. So if the CPU is unplugged you definitely won't get a beep. When you attempted to boot with no RAM installed, a beep code would be expected. Since it …

I remember running a quick performance benchmark on a brand new SMR drive.

I think there's an error of translation here. The parts I think you're asking about are called inductors. I have a standard P2B that has had some parts removed and I recall the inductance value was marked on the board underneath. I'm not at home so I can't find it right now, but it looks like the …

Coppermine support depends on having a new enough BIOS, and having a voltage regulator that supports the voltage the CPU is asking for. The BIOS can be updated, so that's not a problem. For the voltage support there's a workaround - but native support is nicer. For the voltage support you need to …

I had a GX270 board with that same type of heatsink and fan on it. The GX270 is like an older version of the 280 - it's AGP with an i865 chipset and has the older mPGA478 CPU socket. It supports Prescott but the BIOS will underclock at POST if it detects the CPU is too fast, due to power draw. My …

I don't know what would be a typical cause for the board to be stuck in a Reset state. But I believe in always looking at voltages as a first step. Use a multimeter (BIOS readings are unreliable) to check for voltages on the board, see if you find anything that looks weak or unsteady. Primary …

10uF is a common value for capacitance, 16uF would be extremely odd, especially on PC parts, so definitely 10uF. The reason it's 16V is simply because 10uF 16V are commonly available.

Keep in mind that network speed and file transfer speed are very different things. On some systems they'll be similar, but on others there's going to be a big difference. Especially when you use a gigabit adapter on motherboards from the 2000s. "iperf" or it's Java equivalent "jperf" is a good …
