I have tested my 2600+ Mobile and I've gotten the highest of 2.53ghz on 220x11.5 on a DFI Infinity setup and it was prime stable. Now I'm on an ABIT NF7-S and I can't seem to get the same chip up and over the 180 front side bus barrier. Even when giving full northbridge voltage and running something like 190x9 I can't get this thing to go stable. Is this a weaker or crappier NF7-S that I just got unlucky with or are there a few more things that I could try to get it up there. I would be happy with 200 - 210 right now.
