Problems With Overclocking Opteron 165

I'm what you could call a newbie overclocker, but I've stayed glued to HardForum and other forums to learn all I could. I recently got my new rig up, and am having problems. I'm sure there's something very obvious that I'm missing; I would appreciate any help.

My specs:
Opteron 165 0551UPMW
Asus A8N-E
Zalman CNPS9500
Kingston HyperX 1GB (2 x 512) PC3200

I started off overclocking like how I thought I was supposed to. I went into the BIOS and began gradually putting up the HTT (I believe) from 200 up in 5mhz incremenets, then booting and running Super_PI for about an hour. If I was leaving, I would Prime95 until I came back. I did not mess with the voltages, yet - I left it on auto.

I got up to about 235 on HTT and ran into problems. Mainly, Windows would begin loading and just freeze. So, I would reboot and back off some, but it would still freeze. So, I reinstalled windows. Nada.

I read about memory dividers but it's still not real clear to me what to adjust. I went into my BIOS and couldn't find anything specifically about dividers. I lowered my RAM speed from PC400 to PC333, thinking maybe that's what I was supposed to do. Suffice to say, it didn't really help. I then went and cranked up the CPU voltage higher, but that didn't really help.

Sometimes it will get into Windows, sometimes it will freeze when loading, sometimes it will freeze within a few minutes, etc.. It's not my temperature; idle I'm running about 28-29 degrees, and under full load maybe 35. Then, after rebooting 5 times (sometimes I seriously have to) and backing off quite a bit, it's able to boot back up, but I'm right back where I was before.

If it helps, for some reason, just with 2 instances of CPU-Z, Firefox, and the regular Zonealarm/Trillian/Google Desktop search running in the background, ASUSProbe shows I'm using around 40 percent of my memory.

I have not adjusted the timings or done anything with the memory, really. This is all just frustrating. I can't get past about 2.15 ghz without Windows going nuts or it failing. So, any help is appreciated. Here's a link to screenshot:

Without running a memory divider, you're RAM is essentially running at the same speed as your HTT. Now, Kingston HyperX is good stuff, and it will go beyond its stock speed, but not to 235+. This is where the RAM divider comes in. Running a RAM divider, you can set the RAM to run at say, 2/3 of the HTT speed. So this comes in handy when you set your HTT to 300 mhz, because your RAM will still be able to run at 200 mhz. I don?t know much about Asus mobos, so I suggest you look through your manual or google around
