The real thing limiting me now is just my motherboard. It doesn't seem to be stable at anything passed 3.5 unless I give it ridiculous volts (1.5-1.55v). I'm also not sure what voltage to use for the NB. In the XBit Labs PII 920 review they used 1.55v vcore and 1.4v on the NB for 3.77GHz. Considering the 920 is 2.8Hz default, 977Mhz overclock using 1.55v seems about right. The NB however, 1.4v seems like OVERKILL for only 2,100+ frequency. I need to talk to Kei, he seems like the PII 920 master.
