BEST i845* motherboard? for overclocking FSB to the MAX!

[syadnom]

what is the best motherboard for overclocking to very high FSB speed?

1. 
   P4B533-v
   P4B533-e
   4G4A
   GA-8IEXP
   IT7
   BG7
   BD72 (-raid??)

to take a P4 533bus(133) to 664+

features are unimportant, just the raw ability to overclock.

4G4A. Uses the faster 845G chipset, has maybe the best memory divider options, and great ocing.

explain where you get this:

Text 4G4A. Uses the faster 845G chipset

the 845G is just an 845E with onboard video, the chip is not any faster as it is the same thing with the addition of onboard video.

also, i have found that in most cases, the 845G chips do not allow as high of FSB, as the onboard video cannot handle the speeds, even when disabled.

please, if you have some contrary information, post it.

the point of this thread is to find the mobo with the highest stable FSB.

I have noticed a trend in people wanting to take a P4B(533) chip and run it with a 166Mhz bus, most instances taking a 2.4B to 3.0Ghz with PC2700 RAM.

i think he meant that 845g supports ddr 333 while the 845e does not

Anandtech's 845G/E ReviewLook at 845G even with only DDR266, it does have a slight advantage.

In any case, I do realize that isn't the point of the original question.

I don't have any personal experience, but her's what I know. The 4G4A has better memory dividers than both the P4B533 boards (I believe they force 1:1 ratio at 133fsb and above). I have heard some massive oc's tho on the IT7. But, the board that I have heard the best stuff about is the 4G4A. I'll dig up some reviews.........

The P4B533-V has 3:4 above 132fsb with the latest bios update, and the P4B533 and -E has it via a dip switch setting. I'm not sure if the -V has 4:5 above 132fsb tho.

here, a little more information.

i dont really care about the memory dividers, i want to run:

PCI/AGP LOCKED at stock
FSB for RAM and CPU sycronise @ 166Mhz , no fancy dividers, just 1:1

i dont really care about the memory dividers, i want to run:

Then you could get the ol P4b266-c. Inexpensive but a solid board.

i was kinda wondering this same question. I wanted to kinda know what board would be best. But I kinda narrowed it down to the Asus P4B533-E or the Abit IT7. I know the reputation for both companies are good. But in terms of OC and overall performance which would be best. Thanks.

the asus p4b 533vm is a 845g that does not have onboard graphics..
I compared the two:

when all systems were the same, it benched SLIGHTLY ahead of the 845e
No real world difference though.

I used to own an abit bg7 (845g) and currently run an abit bd7-II raid (845e) and I can tell you for a fact that the bg7 is faster than the bd7-II using the exact same components: p4 1.6a, xms3200

at 150fsb/ddr400 (3:4) for the bd7-II, I get a score of about 96xx in 3dmark

at 150fsb/ddr387 (4:5) for the bg7, I get a score of 101xx

for the bd7-II to equal the score of the bg7, I have to run it at 158fsb/ddr421

also, i have found that in most cases, the 845G chips do not allow as high of FSB, as the onboard video cannot handle the speeds, even when disabled.

not true. I could get all the way up to 175fsb 1:1 using the high h/w strap. it seems that the 845g is only unstable at high fsb using the 4:5 divider (160ish seems to be the limit) and 3:4 is very ustable past 133fsb.

the point of this thread is to find the mobo with the highest stable FSB.

I think most of the 845x boards will be stable at high fsb as long as you use 1:1 and your memory can handle it. (epox boards notwithstanding, but thats a different thread)
