If you are looking for a BX board, you pretty much have two choices a Asus CUBX or a Abit Be6-2. Look no further.

Does the ASUS CUBX operate in any different way at 133fsb as compared to the P3B-F ???

Its kinda pricey but its all I use Shuttle Hot-649a.
My fastest setup so far is dual 800 p3's with 133mhz fsb.
1/4 agp works flawless.

All of the ASUS boards since the original P2B have it.

Hi All:

___Do any of you remember taking a PII 233 (Clock limited so I was using the 2.5 multiplier) to 133 MHz FSB on an original Abit BH6 using Samsung GH ~ 3 yr?s ago? I was running at that frequency for quite some time on my own rig until the PII 300 SL2W8 went to 504 for me. I ran this because of an article Anand had posted way back than about all BX chipsets defaulting to the ¼ PCI/IDE divider at 133 MHz FSB. He recently reposted that same article in one of the BX@133 video card reviews. I cannot say that all BX chipsets do this but I know for a fact that Abit did not design this into their first OC?ing boards and I do not think anyone else did either. It was an undocumented feature of the Intel BX chipset itself. The only confusing thing to me today is that the current boards that can switch to the ¼ divider like my current BH6 ver. 1.1 do have a 1/3 divider available above 124 MHz FSB for whatever reason even though the ¼ divider is their as well at the higher FSB?s. No guarantee?s but I can bet as long as the MB makers didn?t screw with the 1/3 and ¼ dividers in the first place, the 133 MHz FSB w/ a ¼ divider is still in tact for the majority of older BX boards out there.

___Good Luck

xcel: The PCI divider is not a function of the chipset.

The BH6 was already a 2nd generation BX board for Abit, the BX6 did not have the 1/4 PCI divider. By that time, I would say that Abit would have seen the need to implement that setting, as ASUS already had on their 1st generation P2B.
