My 440BX system's in a case that looks identical to that one.

Replace ALL the capacitors on the motherboard (except the 100uF and smaller). The caps on this board (TAYEH brand) are well known to go bad without any visible bulging. Same goes for the others (I'm seeing Hermei around the AGP slot)

When I compared various Orion slot A's on a KA7 motherboard (based on VIA KX133), I noticed that the 1 GHz Orion kept hanging up. When I swapped out the heatsink for a heavy copper monster with noisy fan, the 1 GHz Orion stopped hanging. Perhaps your issue is cooling related; or perhaps not. Worth a …

I'm jealous of your Slot A 1Ghz! Doesn't help you but bit of reading that may interest you http://redhill.net.au/b/b-00.html

Did you try an Orion-based, 1 GHz slot 1 in the motherboard you are having trouble with?

Did you try an Orion-based, 1 GHz slot 1 in the motherboard you are having trouble with? I only have Thunderbird Slot A CPUs here. The 750MHz Thunderbird works fine, also with 110MHz FSB @825MHz. Here you can see the system in demonstration after building and making a video: https://www.youtube.com …

Hello there , back in the days i used to use my epox k7xa as my main rig.I had bought a week 52 slot a 550mhz cpu which was in fact an 750mhz 0.25m which i had overclocked successfully to 900mhz using a vos32 globalwin heatsink.Later on i bought a thunderbird 1gig and the epox could not even post .I …

It seems the system is unstable when running FSB at 166MHz, which is the correct frequency for this CPU. Going by what you said RAM seems to run fine at 333MHz (166MHz DDR). To start troubleshooting I would check CPU temperature first, memory timings (maybe try command rate at 2T), try to increase …

The CPU speed it "Multiplier" times "External frequency", so 1666 MHz at your manual settings. It could be your PSU isn't strong to run the CPU at full speed. Or maybe it gets to hot. Just guessing now.

I have seen remarked Athlon CPUs. Carefully inspect the cpu for tampering around the CPU selection jumpers.

Thanks ... I checked the current rating on the 5v line of the new PSU and it's the same as the old PSU. I just pulled the RAM and I see that one module is a crucial pc3200 512 ddr (I think 400MHz) and the other is a crucial (I think pc2700) 512 ddr 333MHz. I think I have mis-matched RAM?

Ok ... it looks like the pc3200 may be the culprit ... but I can't tell if it's 400Mhz. Can someone see a marking on that module that indicates whether it's 333 or 400MHz? Thanks in advance.
Re: ASUS A7V333-X mobo, AMD Athlon 2800+ CPU question

^PC3200 == 400MHz. PC2700 == 333MHz. They are different ways to say the same thing. Your board supports 333MHz memory operation and that is how it seems to be set in the BIOS, so both modules will be running at 333MHz. It doesn't matter in this case that they're mismatched. What you can try is …

The regular a7v333 has a few funny undocumented jumpers, at least one of which silently boosts voltages. I don't know about the x version, but I'd inspect the jumper configuration to be sure.
