As the title suggests, I'm working on a project trying to Overclock an AMD K6-2+/500. I have some spare water parts now so set up a water cooling loop for it (Yep, I like extremes) and I got it running windows 2000 and got to desktop and playing around with it at 622 Mhz, but the moment I started 3dmark 2000 with my geforce 2 ultra it shut off. This is a classic sign of insufficient power, so now I'm looking for a question to be answered from the community.
And before you comment about cooling, I've already found out that at 620 mhz this chip won't even turn on / POST below 2.9v (even though it's rated for 2.0v originally), and even then it won't even come on unless the water cooling is already running and cooling first. It just sits there and never does anything when turned on if the water part is off. But turn on the water cooling and hit the power switch and it comes right on and boots. So apparently it does like it.
These chips with the AGP card powered by the AGP slot, is this going to use more of the +5v rail on a power supply, or more of the +12v rail on a power supply? I have power supplies that have big rails either way, one with 35 amp for +5v, and one with 40 amp for +12v, so I need to figure out which to use.
The motherboard has only an AT power connector, but I have an ATX-to-AT adapter so I can use anything with it.
Any input would be appreciated, and this might be why I can't get the thing to come on at 700+ mhz too.
Edit: I'm just using a 250 watt AT power supply right now.
