Motherboard, Memory, & Power Supply--Info Needed

[stilholm]

I have tried to install 2 KHX3200/512 modules on my Asus P4C800 Deluxe motherboard. Initially, I couldn't get the system to boot into Win XP Pro. With the latest bios from Asus, version 1007 beta 006, I was able to finally boot into Win XP Pro. However, I get small crashes and system instability. I allow the motherboard to set all the system bus and memory speeds automatically. It is definitely the memory because to troubleshoot, I bought a KVR333X64C25/265 module and the system runs flawlessly. In addition, I installed one KHX3200/512 module in single-channel mode, and my system seems to work perfectly. I am now thinking that my problem may be if I have enough power to run 1GB of KHX3200 memory in dual-channel mode. I currently have a 330W power supply.

Here are my current system specs:
Win XP Pro
Pentium 4 3.0Ghz/800 MHz FSB
Yamaha CRW2200E CD-RW Drive
Creative DVD2240E DVD Drive
Creative SoundBlaster Live! Gold
80 GB Western Digital 7200RPM Drive
45 GB Western Digital 7200RPM Drive
Creative Annihilator 2 Ultra (NVIDIA Geforce 2 Ultra)
Enermax 330 Watt power supply
2 80mm Case fans

Will a higher wattage power supply result in the 1GB of KHX3200 being more stable? Also, I plan to buy a Radeon 9800 Pro in a few weeks, should I upgrade the power supply anyway even though ATI only requires 300W power supply?

I would <A HREF="http://memtest86.com/" target="_new">test</A> your memory. It could be you PS, but it sounds more like a bad memory module.

I've tried running memtest86 3.0 several times. Every time my system hangs, even with the 256MB memory module. Does this mean my motherboard or processor is bad?
