Overclocking a Barton...?

Hi!

I've done a lot of research on overclocking a Barton, in particular the
Athlob XP 2600+ model. Virtually everywhere I go it says it could *easily*
reach a FSB of 200Mhz...%$*&%...I can only get to 170Mhz until my computer
fails to boot up.

I have the ASUS A7N8X deluxe. Argueably one of the best Athlon XP mobos
around but yet cannot do a 200MHz everyone been talking about. What am I
doing wrong?

My RAM is PC3200 but currently in-sync with the FSB at 168MHz (2 Mhz above
default). Multiplier at 11.5x (default).

I consider my CPU cooling to be very good: full load at ~45C ; idle at ~35C

Memory in "agressive" mode with the following parameters: CAS latency 2.5,
RAS to CAS 3, RAS precharge, 3 and TRas 7.

Any advice on what else I could do to get closer to the 200MHz mark with my
A7N8X?

Thanks!!!

I've found it could not be done on both my systems without increasing vcore
to 1.75v from 1.65v. With this, they're both rock solid at 2200Mhz (200fsb).
Both have higher performance coolers that the stock hs/f. Both idles at
39-40C and max load around 49C

How old is your Asus A7N8X mobo? Look at:
http://www.asus.com/products/mb/socketa/a7n8x-d/overview.htm
If your mobo is version 1.06 or older you may have to update your bios
before the mobo will be able to handle 200fsb.

Good luck

What version of the A7N8X do you have?.... only version 2 or later has full
support for 200FSB.
Overclockability of chips varies greatly. If your chip is quite new then I
would expect it to do 2.3GHz (11.5 x 200) easily but if it's an older
stepping then it's likely that it won't do it no matter what voltage you
give it.
The other thing to check is the timings of your memory. A lot of PC3200
memory is only rated for CAS 3 when running at full speed.... try setting
the memory to 'By SPD' (or 'Auto') timings. You could also try setting the
memory to run at 200MHz with the FSB at default 166 (5/6 ratio) just to make
sure the memory is up to it.

It's the Deluxe version 2. With BIOS 1.07 I think.

I have been using 166FSB with 200MHz memory speed for most of my pc's
computing life. Only recently I've tried expereinting with increasing FSB.

What I'm afraid of is increasing voltage...would 1.75V be enough to cook my
cpu? :)

Just keep it cool enough so it doesn't re-boot/crash, and it should last
years.

overclocking basicly means, add more mhz until your cpu (or northbridge or
whatever) get too hot
too hot for barton imo means 60c or more, try and keep it 50-55 max (at
100%, not idle)

my 'old' barton will do 2.3 easy enough, not quite sure about 2.4 (200fsb)
it wanted more vcore than i wanted to put in it really

Like I said... the overclockability varies, even for the same stepping and
week number. But it's true to say that generally the later weeks o/c better
than the early ones. I've had four XP2500+ CPU's made around week 20 of 2004
or later and they all did 2.3 - 2.4GHz on default voltage. The early
XP2500+'s I had were lucky to do 2.2GHz, even with more volts. It's normal
for the average quality of chips to improve as the manufacturing process is
refined over time... but that's not to say that you can't find a few good
chips from early batch numbers.

ya i'd agree in general really early cpu's arn't quite as good
maybe i got lucky, my xp2500 wasn't that much better than my mate who got
his unlocked xp2500 a few weeks before me

my cpu info: dunno any more detail than that without taking it out, can't be
arsed with that heh

I think that version 1 or later has full support..
I think that it was like 1.04 or something like that

The multiplier of my CPU is unlocked. What version of CPU is that.

He is talking about the revision of the motherboard not the CPU. Official
200MHz FSB support 'out of the box' only came with the Rev 2.0 board which
had the NF2 Ultra 400 chip set.... however from Rev 1.06 200FSB support can
be achieved by flashing the latest BIOS. I suggest you check the Rev of your
board and if it's earlier than 1.06 then it does not have official 200FSB
support. If it's 1.06 or higher (but below 2.0) then you need the latest
BIOS to achieve 200FSB. If it's Rev 2.0 then you have 200FSB support out of
the box.

What rev is your board?

If you want to know the code of your CPU you will have to remove it and read
the batch code number off it. How old is it and how do you know that it's
unlocked?

It's definately Rev 2.0 it's part of the product title of the mobo 😀

But there's this jumper on the board which has to be swtiched to utilised
this 200MHz. But strangely I can select 200MHz without moving the jumper.

I had the same problem as you have and I could not get over 278 or
something like that.And I been trying for almost a year.Then a couple of
guys Ozone and Wes made me understand the problem at last.
The thing is that when you raise your fsb and your agp bus are at auto
you raise your agp and pci buses as well.I don't know where to set the
pci bus by it self but by changing my agp to 66% the pci bus was doing
the half of that 33 mhz and thats the speed it's made for.I was suddenly
able to run my board at 200 instead of 178.And I've changed my memory
settings to 80% so they run the speed they can take.
That's the way to do it and I run mine at 11*200 now and my puter sees
the processor as one XP 3200.And I use default voltage all around and it
just runs great
good luck

Thanks for the advice!

My AGP bus is at auto...maybe I should force it to 66Mhz the default. I'll
let you know if it works. 😀
