Has my xp2000 reached its limit?

Hello,

I have an xp 2000 T-bred B (jiuhb 0321 wpmw), Asus A7N8X-X, and PC3200 RAM.

Right now I'm OCed to 204 X 9.5 = 1940MHz at default voltage (1.6), totally stable. The problem is that I can't go any higher than this, even if I raise vcore to 1.8. My temps are fine (35 idle, 43 load) and I've tried increasing vdimm too. No matter what comination of fsb X multi I use, I can't seem to run this cpu over 2000MHz.

Have I hit the limit? It seems strange to me that it can be stable with default voltage at 1940 but my computer won't even POST at 2000. Has anyone else encountered this kind of problem?

What PSU? What cooling?

I have OKIA 350 watt PSU and Spire Falconrock II cooler, not the greatest cooler, i know, but my temps aren't bad. I suspected the power supply already, so I unhooked my CDRW and floppy drives from the power supply, still couldn't OC any higher.

Your CD drives and Floppy drives consume about 10W of power over both 5v and 12v rails each, so they do not contribute any significant amount to the power load. I would definitely recommend getting a new PSU.
