Need assistance with my P4B533-VM please...

I got a 1.6A to go right up to 2.4 (150Mhz bus, 600Mhz QDR) but it turns out to not be as stable as I originally thought. Runs Prime95 for days, but the machine will not boot into Quake 3 Arena or do the DXDIAG Direct 3D Acceleration test without locking up. I have to turn it down to 2224 (139Mhz bus, 556Mhz QDR) to get it stable.

Now I know this chip has it in it to do 2400 or greater, but I am limited by the BIOS. No voltage adjustment is the biggest thing. I bet if I had 1.6V available it would stablize. Also, there are very limited frequency items in the BIOS - weird CPU/Mem ratios (just 1:1 and 4:3), no AGP/PCI bus lock etc.

I have the memory (Samsung true 2700 6ns) set close to max at 2/2/2/5 (the SPD has it set to 2/3/3/6), but I don't think that's the issue. I understand this RAM to be ultra-stable, that's why I haven't been messing with it.

Anyone have experience with this board and how to overcome its limitations?

I'm in the same situation, except I'm a couple of steps behind you. I'm still in the process of trying to find a mATX motherboard that has the settings to allow a northwood to push it to 2.4ghz. The other thing I'm looking for is SPDIF output on the motherboard (via ALS 650 or CMI 8738 I assume). Does anyone know a board that fits this description?

It is not cool to come in and hijack someone's thread with your own topic. You need to start a thread of your own.

My original question still stands.
