MSI KT4, Barton 2500+ overclock help

Trying to get the best out of this combo but not really winning
Currently I have got it to 176 FSB and 12.5 X CPU for a speed of 2195.
I,m sure I should be able to get the FSB higher but it wont stay stable
above this, infact it wont even boot into the OS.
Memory is Crucial 512 DDR 3200 and I have the bios set to run the memory at
its rated 400 mhz
Full system spec is

MSI KT4 Ultra motherboard
AMD XP 2500+ Barton CPU (v.core now at 1.7)
Crucial 512 DDR 3200
MSI Geforce FX 5600 (non Ultra)
Maxtor 80Gb7200rpm 8mb Buffer ATA 133 hard drive (not serial)
Pioneer A05 DVD RW
Lite-On 52X32X52 CDRW
PCI Ethernet Card

Ideally I would like to get the FSB up to and above 200 and drop the
multiplier down to maintain 2.2 ish on the CPU

Any suggestions would be gratefully recieved
Cheers
Helinut

I do not think the fsb of a KT400 based board can go to 200MHz due to the
multiplier not having a divider at the 199MHZ mark to get the pci back down
to 33MHz, like it does at 166MHz - Some boards might allow it - but I do not
know.

I have a KT333 based board and the most I can get the fsb to is 182MHz,
after which the pci is too far out and the system will not even post - looks
like changing the multiplier is the only option to get the cpu frequency
further

Thanks, It seems a shame that in such a versatile board MSI didnt consider
putting this option in the BIOS.
Oh well, I can still get 2100 mhz out of the bugger to make it a 2800+ : )

Hi, MSI can't put this option into the bios as it is a 'feature' of the KT
chipsets, even the KT600 has this problem with the divider......

Oh, OK I wasnt aware of that, but then again thats why I frequent this
newsgroup. Thanks for the input

But what you can do is use the wire-pin mod at www.ocinside.de to access
the higher multipliers and keep the fsb down.

I am currently using a 14 x multiplier at 167Mhz = 2340MHz.

I have not yet tried the multiplier any higher yet but the cpu will go
further, just that my generic pc2100 ram does not seem to like much of an
OC.
Have yet to try 15 x (2505Mhz) as have been trying to sort out cooling - am
using a vcore of 2.0v that my motherboard has an undocumented function for.

You've got some courage to run your Vcore at 2.0V -- I'm worried about running
my 2800+ Barton at 1.92V. I flat-out fried a 1.2Ghz Tbird by running it at 2.1V
Vcore. It took some time (about 3 months), but one day it just wouldn't boot.

Hopefully not fools courage. I am a bit concerned, but 2.0v is the next
step up from 1.85v for me, so I do not have that much choice if I want to
get past the mid 2000Mhz mark. The temperatures I thought were reasonable
33/21C at idle 47/22C full load.

How hot was the t'bird getting? and how old was the t'bird?
- just so can make some comparative analysis and try and convince myself
everything will be ok.

The Tbird was the first 1200 (not the one designed to run on a 133Mhz FSB, but
the 100Mhz FSB). My Barton runs a LOT hotter than yours. (I'm running 47 [117
farenheit] right now, basically idle). The Tbird ran slightly cooler --
somewhere 108 farenheit and 117 load. That Tbird was old though and I ran it
overclocked and at max voltage it's entire life. If the Barton fries a year
from now it won't bother me since it'll be dirt-cheap to buy by then.
