ASUS A7N8X over 200mhz FSB?

My A7N8X rev 1.04 will not run anything past 205 stable. I can get into windows at 220 @ 2.5 - 4 - 4 - 11 but it just isnt stable no matter what, although I doubt its my ram, it could be.

Absolutly, if you get a revision 2 pcb, and everything else is up to it, that range should not be difficult. The rev 2 boards are guaranteed to run 400mhz, so 430 isn't even a 10% overclock. I have a a7n8x-e (all e boards are rev 2), and it gave my memory all it could handle out of the box. 218 fsb, memtest, prime 95, 3d mark all stable.
That is with year+ old, unmatched, 2x 256 corsair xms pc 3200 running at 2.8v 11,4,3,2. And my default chipset voltage is low, it varies from 1.555 and 1.565. In process of fixing both of those and I am anxious to see where I can go from there.
Where you would lose to abit and some others is vcore tops at 1.85v, chipset default at ~1.6v (need mod to change it), and vdimm tops at 2.8v. Abit has higher options for all and can change the chipset voltage out of the box.
So the question is, do you need higher voltages and do you like/can you do mods? Most likely you will need mods to get over 440mhz.
Abit nf7-s is cheaper too, so that's another thing to think about.

I have the 2.0 version that supports 400mhz, but It seems that I need higher voltage to get my overclock stable at 210mhz. I get various errors in XP pro and crashes running games. Also I get a couple memory errors, even after upping the ram voltage. My OC is perfect at 200fsb. Im running a barton 2600+ @ 11.5x200=2300. I do not want to risk any mods for I dont have the cash to get a replacement if i screw up.
Guess Im stuck with 11.5x200 =|

I have gotten my system to boot at a 220 (440mhz) FSB, but everything else isn't stable.
I am running @ a 210x11.5 right now, @ 1.725 vcore, and all is well and stable.
I can run @ 200x11 at 1.65vcore, with everything extremely stable
2500+ unlocked.

As of now, I found out without the peltier, and or water cooling, and replacing heatsinks on the bridge, and a whole slew of other things, I am not getting past 205.
It locks in games, and loads of fun. It could just be my video card, which has been OC'ed to the max I think.
Anyways, I am going to run prime95 tonight, see if I am stable at 2200 mhz, then tomorrow I would try to hit up 2400 mhz, and look into volt mods for the mobo, so eventually I can hit, say 2.8 ghz.

The key here is having memory to support where you want to go. I bought PC3200 memory to OC my 2500 Barton to 3200. I can go as high at 208 X 10, but it is unstable (P95 failure). I am very stable at 200 X 11 and that's what my memory is rated (400Mhz).
Memory is the critical component you will need to invest to get higher speeds with stability. Of course you are looking at $300 easy to get high performance stuff at 1G memory.

Bringing past 400 wont break the chip, if powered good(stable rails) and cooled properly.
Hell, the old T-bred were rated at 266, and some of those are pushing 400 mhz, thats good in my book.
I might try to sell my ASUS and try to find a decent ABit somewhere.

Whenever I went past 200 fsb I would get errors in MemTest 86, test #5. At 200 I get zero errors. I think I need more vdimm to get it any higher. The uber bios' have the option to raise it to 2.9v.
Just curious ... especially for those of you with an FSB over 200 ... have you used MemTest 86 to check your ram for errors? Was it error free (I run all 7-tests ... for 5-full passes)?

I've run Prime95 for 6hrs at 215x11, but normal operating is 210x11 which is 24hrs prime95 stable. 218x11 was a no go.

Wow...very impressive. What is your vdimm (ddr voltage) set to?
I would be curious to know how your machine does in memtest 86 tests (especially that pesky test #5). I ran all 7-default-tests for 5-passes.

I have loaded windows at 225, and I cant show proof but i have gotten 233 out of it loaded into windows, but it was a one time thing, and since i updated my bious can no longer reach that. I will look for a wincpuid screeny...
I have a rev 1.04
Edit: I found my screeny of the 233.8 (467MHz) a7n8x boot into windows. No volt mods, and no uber bios (which doesnt work anyways) Let me host the picture somewhere and i will post it. gimme 5 mintues.
Edit: I have no proof that this is from my A7N8X, but i would not lie, so just trust me. And remember, this is not stable, just the highest i could boot into windows with. The only other option in the bios at the time was 240MHz, my bios got corrupted when i tried that, so i reflashed, and did not try 240 again.

I believe you, my problem with my rev 1 was always getting 3d apps to work over 195, or 210 after vdd mod. Prime was always stable higher than that.
I didn't bother pushing it higher because I wanted those 3d games to work, and i didn't feel like corrupting the bios.
