A7N8X R2.0...I Thought they Fixed this problem?!?

[Archer]

I have this board and an a barton 2500+ Processor. I have tested this chip
to 2250mhz stable (prime95 for 24hours, 3dmark 2001SE looping Demo, memtest,
etc) However, when I try to run it at 200mhz fsb, even if I drop the
multiplier as low as 10.5 (2100mhz) it is completely unstable with errors in
prime 95 blue screens etc. I have ocz el pc3500 memory which I have tested
in memtest with 5-2-2-2 timings stable at 200mhz. I have set the timings to
6-3-3-2 according to ocz for 200mhz. I can only assume it is the chipset.
I'm currently running at 180mhz x 12 for 2160mhz completely stable. Correct
me if I'm wrong, but I thought they fixed the chipset issues with the 2.0
revision of this board. Another thing. My board came with the 1003bios on
it. I updated to 1005 and this seemed to make the situation worse. Are
there any issues with this bios. I have an ocz gladiator heatsink with the
delta screamer on my chip so my temps under full load never get above 43C.
The Specs are to follow

Antec truepower 430 w power supply
Athlon XP2500+
512 Meg OCZ EL PC3500 Memory
Geforce FX 5200 Ultra Video Card
Using all onboard options

Memory is in sync with fsb
timings are 6-3-3-2
cpu interface - aggressive
cpu voltage at 1.7
memory voltage at 2.7

Any suggestions as to why I'm having this problem would really be
appreciated

My non-Dlx came with 1003 as well, been using 1004 for about a month now
with no problems at all. Heard others cry about 1005 too, have your
tried 1004?

A7N8X (non-dlx) v2.00, Barton 2800+ @ 210x11, Corsair PC3200LL @ 6-3-2-2

I've got a revision 1.04 Deluxe running the 1004 BIOS and I have no problems
whatsoever at 200MHz FSB, even with (relatively) cheap Samsung PC3200... Try
upping the vcore a little more ~ 1.7v seems a little low to me, I needed
1.775v to get my 166MHz XP2600+ stable at 200x11.5. If that don't help then
pffftt, ye got me...!

No I haven't tried 1004. I was under the mistaken belief that I should go
with the latest bios. I neglected to put in my first post that I have the
deluxe model. I suppose I should be happy where I'm at but with the
revision 2 board the 200mhz settings (and above) aren't supposed to be an
issue. My old revision 1.04 board was better. It probably is a bios issue.

Thanks

Please let me know if 1004 bios fixes fsb issue

Please let me know if 1004 bios fixes fsb issue

Well, it did on my 1.04 board... your revision 2.0 is a different story.
Always worth a try I guess...

Had *exactly* the same experience myself with BIOS 1005. Changed to the
1004 Uber BIOS and can now get up to 210FSB without problems. Suggest
you give it a try.
