How high a FSB were you getting with just 1.65v in the MCH ?

My ES modded mobo is about FSB 560 1.65V in BIOS, but I don't know retail box how high did it get.

My retail board is hitting 540FSB at 1.65V, 525FSB at 1.45V. I have a modded ES board arriving that is suppose to do up to 600 although it will require a heck of a Northbridge cooler. ;)

A new tool (SetFSB) was introduced to the public.
Thank you. abo.

Well yeah that seems to be the issue- total frequency still matters. Still it is nice to know this mobo can max out a E6300 chip with 7x multi. My DS3 will likely need the 8x multi of the e6400 to reach the true potential of the allendale core.

nah man even this board is not even close maxing out really good E6300 CPUs....... well at least not my mobo...the chip is priming happily at 1.38v on 3.6GHz.......this chip would most certainly go to 4Ghz but my mobo is not even close to 571MHz FSB :(

My best FSB on an unmodded P5B Deluxe = 520FSB X 7 for 3.64:

522 is where instability starts to crop up and 529 will freeze my system in the BIOS. The board will actually do a flat 500 x 7 with just a slight bump to the vcore, 2.25 on the memory and auto on the NB.

Dividers are terrible with the 0507 BIOS. I am pretty much required to stay 1:1.
