Does anyone had any trouble hiting the 200FSB with that mobo with revisions lower than 2.0?

Yes i have an a7n8x which can hit 185mhz fsb but is a little fluky
i have found the sweet spot for a7n8x pre 2.0 is 175mhz

My a7n8x is a 1.04 and ive used 2 types of ram kingston hyperx3500 and corsair 3200LL

got an xp1700 @ 2.013ghz 175mhz fsb 1.7v core running 100% stable right now

I just killed my rev 1.04, but I did have it running stable at 210MHz FSB 1:1 with my memory. CPU couldn't handle it though and 1.7 volts with a slk-800 and panaflo L1A = high temps

I got A7N8X Deluxe rev 1.03 and i'm afraid that i will not be able to hit 200FSB with my Athlon 2500!

Maybe the upgarde of a BIOS (v.1004-200MHz support) would help!

What Bios do you have?
The Upgradee of the Bios might help.

I have a rev 1.04 and I've been trying to get 200MHz FSB stable, but it looks like it's not gonna happen. The highest stable setting I've found is 186MHz. Right now I'm testing a 2500+ @ 2.32GHz. Really want 200MHz FSB, but is it worth it to go through the trouble of swapping the board for a rev. 2.0?

What BIOS version do you have? Did you upgrade the BIOS?

Just because the new BIOS supports up to 200MHz fsb in 1MHz increments doesn't mean that the board will hit the 200MHz fsb mark. It is strictly a limitation of the chipset. If you aren't using a revision 2.0 board, then it uses the original nforce2 chipset, not the nforce2 ultra 400 chipset. Like others have already mentioned above, the sweet spot for the original chipset is roughly 175MHz fsb. In AnandTech's nForce2 6-way Motherboard Roundup, they were able to OC the fsb to 185MHz without sacrificing stability. So unless you have a rev2 board (that utilizes the nforce2 ultra 400 chipset) don't expect your nforce2 board to OC to 200MHz fsb. it sucks, i know...

What memory should I buy then with my Barton 2500, pc 2700???
I want both running at hte same speed to get the best dual channel resaults.

Well, knowing that the average OC of the original nforce2 chipset is 175MHz, and assuming that you'll get the same 185MHz OC using the ASUS A7N8X, you should be fine with some quality PC2700 (DDR333). If you want your CPU : DRAM ratio to be 1:1, you won't be OCing the RAM very much. But make sure the memory you get is quality (i.e. Corsair, Mushkin, Crucial, Samsung), or else you might have problems running it at any speed over 333MHz (166fsb). You could also maybe get some quality PC3200 and just underclock it by using a 1:1 ratio again. Then maybe in the near future if you have money to upgrade your mobo, you could get one that provides a 200MHz+ fsb, and you'll already have the PC3200 to run on it (and maybe OC it).
