The problem was the motherboard could not function properly with this particular RAM at 667Mhz no matter what other settings I chose. I had video BIOS cached ON/OFF, RAM timings conservative/aggressive, this, that and the other and it just wouldn't work. Perhaps in another BIOS update, Jetway will fix this issue or perhaps give us the option to bump up the VDIMM which may fix this.

I ended up just sticking with it. I was going to get a couple sticks of Patriot or Corsair which would run nat 4 and 3 CAS respectively but figured the boost in speed would be negligible since the machine was already much faster than really necessary. I was just being a geek. So with this Mushkin Enhanced RAM, 533Mhz with 4-4-4-10 timings should be fine. I ran a burnin test on those settings for a day with no errors, bluescreens or shutdowns. I had video BIOS cached ON and everything else set aggressively, but left it at 533.

\\EDIT: Yes, I took it to work and tried another PSU as well with no luck (three PSUs I tried total). I will just live with it and maybe it'll get fixed one day. Still 4CAS@533Mhz is roughly equivalent in speed to 5CAS@667Mhz which most of the RAM operates at anyway except for a select few sticks of RAM.
