Maybe being first shipment, Intel didn't bin their first batch of i7 920s as tightly as they do now ???
First of all, great bclks.... and this is a beautiful board for clocking i7s.

We have found the first batch of i920s with lot codes of 3834 just suck, or least the ones we have currently. Neither of them will do more than 200 bclk on any X58 board regardless of VCore or VTT settings. Raja's 3836 is almost as good as your 3836s and the two 3837s I have will reach the same clock speed as Raja's lot or yours, but needs about .10V more VTT and .05V additional VCore to do it. This often puts me in a situation where VTT has to be raised within Windows via software as I usually get the dreaded C1 error at POST if VTT is above 1.475V or so, which I need considering the additional VTT required by my two chips.

I have a 3841 arriving next week, but was told to stay away from most of the 3838/3840 lots but 3835 is potentially a golden lot along with the 3836-7xx lots. Personally, I think Intel got surprised with the initial demand on the i920 and total lack of demand on the 940/965 and switched those binned chips (before being cut) over to i920s for a short period, reverted back to actual binning, and have switched over once again to control inventories. In the meantime, Raja or I will be visiting you and bringing along Guido to convince you to share your chips.
