In regards to the Northbridge straps and their toughness to reason with sometimes, especially when non-stock multipliers come into play, I wrote a quick program that asks you your Conroe chip, your multiplier, and your FSB. It then tells you about your Northbridge Core Clock, your strap, and your CPU speed. It is nice to be able to quickly calculate if for example downscaling the multi might help or not with performance. You want to be on as low a strap as possible because higher straps mean higher latencies. However, FSB is still more important, much like RAM timings vs. speed. In an ideal configuration, your FSB would be pushing the Northbridge Core Clock so it is just under the ceiling for another strap. Also please note that most boards do not implement all of the straps yet, i.e. on the P5B-Deluxe only the 1066 and 1600 straps are in place, so any reported straps that are non-existent on your board are really the one below it (i.e. the 1333 strap is really still the 1066 on the P5B-Deluxe). Furthermore, you may notice that straps are "pushed forward" on some boards, for example the latency settings that should have occurred at 1333 occur at 1600; My program refers to the straps by when they occur, not by the settings.

I have included both Zip and RAR versions for your convenience. If you'd like to redistribute it, that's fine, and if you post it somewhere please link back to this thread. Enjoy!

zip didn't work for me.... Ill post error

Alright neither are working for me.

400FSB is 1333mhz. 401FSB is 1600mhz. Other than that... very nice!

Hmmm. I tested it on several computers. You might be missing some DLLs.

I was wondering about that. Will update!
EDIT: Actually, since 400FSB is 1600MHz NBCC @ stock multi, a new strap comes into effect right here, as happens with many other "big" numbers, like 266.

Probably, this is pretty much a fresh install of windows.

You know what, you probably need the .NET Framework 2.0. Here it is:

I was about to say that. I've had that 135 error happen so many times it's not even funny.

K it works now. Looks good.

Neat problem, however, it can not reliably report a systems strap.

You see, a P5B remains on the 1066Mhz strap until 400Mhz, at 401Mhz it goes to the 1333Mhz strap. But who knows when it does it on the P5W, DS3, ect.

Well, why would it be on the 1066MHz strap at 400MHz? You see, at 266, it's on the 1066. So, at 400, it'd be on the 1600 strap.
