My problem was never vcore. I couldn't get HTT up high enough for that to matter. Those ancient nVidia chipset boards (MCP55/nForce 3600 Pro) have unstable clock generators just like all the other AMD boards designed around that time. Remember those initial Socket 939 days where people still had to worry about how high they could crank HT ref? Same deal. Boards seem to get to ~220-230 MHz.

I've bought a new board based on AMD's SR5690 chipset, but nothing seems to exist that will allow me to overclock with it. AMD Overdrive crashes when there are > 4 CPUs in a system. I've been talking to the creator of SetFSB and even paid him a good chunk, but for whatever reason he hasn't ever added support for this clock generator. Now his page says something along the lines of he's not going to work on it anymore. I think I'm just boned. All I need is something that can change my HT reference clock for goodness sake.

Anyone know of anything other than SetFSB? I've got money. I can pay someone to develop this thing if that's what it'll take.
