2500+ Barton overclocking help needed

Hi all in group,
I have overclocked my system from standard XP2500+ to XP3200+ by changing
the fsb to 200 from 166 and increasing the cpu vcore voltage to 1.8v from
1.65. The system has samsung original pc3200 ddr mem in dual channel mode (2
X 256MB) on an MSI nforce2 ultra delta M-board. System runs 100% stable at
XP2500+ settings but with the above changes the system keeps rebooting
itself when I try and run 3D mark 2001 benchtest or 3D mark 2003 within a
few seconds. Temperature in bios for the cpu is at 59C despite having an
akasa 3200+ rated heatsink fan.

Question is are there any other adjustments to make/try or is it that some
processors just will not overclock sucessfully and fail where others
succeed? Any advice or suggestions greatly appreciated. Rest os system spec
as below.

MSI Delta Nforce2 ultra M-board
AMD Barton 2500+ processor (retail)
Akasa 3200+ rated heatsink/fan assembly
2 X Samsung original pc3200 ddr mem in dual channel mode
Samsung 120GB 7200rpm H-drive
Samsung 80GB 7200pm H-drive
Philips dvd writer
BTC combi drive
400 Watt PSU (non branded)
Avermedia PCTV card
Creative 5.1 soundblaster live sound card
Chaintech 256MB geforce FX5600 video card
Exhaust blower extractor fan.

As I mentioned earlier system is 100% stable at standard config, but
unstable and rebooting itself when overclocked and bench testing or running
cpu intensive programs.

Thanks in advance guys.

i think it's too much voltage. More voltage more heat

I have 1,7 V when CPU is running 2250MHz
temp is 42-49 (diode readout)
socket readout 37-42
on Zalman 7000A

You have temp 59 on socket sensor,
it is hells high.

Akasa 3200+ rated heatsink/fan assembly
buy better heatsink,
Zalman 7000A-Cu, Thermaltake or Taisol

First guess would be the PSU. The PowerLine 400W I have sucks big time.
Wouldn't even boot an A64 3000+. I've tested 3 really cheap ones. Power
Magic 550W for $15 worked fine as did a $12 500W and $25 600W Lead Power
PSU's.
Akasa coolers aren't known for their great performance either. I think I'd
replace it too. TR2-M1 for $8 should work ok. Might want a stronger fan
for it though. The stock is only 32cfm but very quiet at 21dba.

Took your advice on the TR2-M1. Almost as good as a Vantec Aeroflow! Used on
my son's XP2100 (200x10) based system and prime95 tops out at 44C. Can't be
beat for the $$!

Hi, the core voltage, IMHO, is far too high, reduce it to about 1.65

This is a temperature issue...if your external CPU diode is at 59C, then
core diode is likely high 70's or more. If you're just running the stock
cooler with no case fans, you need to address this ASAP.

The TR2-M2 is a better choice unless you need pretty colored lights. It has
a copper core in the sink instead of the copper plate screwed to the bottom.

Hi all in group,
Will try changing the PSU for a branded one as it could be the problem. I am
presently looking at the pc health status read outs for the PSU and they are
as follows:
+3.3v = 3.31v
+5v = +5.05v
+12v = +11.85v
-12v = -11.70v
-5v = -5.20v
Should the +12v be over +12v or is this ok at +11.85 ?
The cpu temperature is 45C when at 1.65v vcore and 2500+ standard settings
and stable. So do you still think the akasa fan may at fault as well?
Thanks for any further input.
Dave

45C external CPU at idle and at stock Vcore is excessive, unless your room
temp is very high (30C or more). I'm not familiar with your fan/hs assembly,
but if it's producing those kinds of idle temps not overclocked at the very
least I would be removing it and checking for proper contact and paste
application. Or replacing it.

No, the stock Vcore for the Barton core is 1.60.

45C is about right for 1.65 V , (depending on room temp and case
ventilation of course but not alarming in itself)

I have found my XP2000+ on a KX7-333 with pc2700 DDR will run best at
FSB=176 x12,5 command=fast . I had to push Vio from 3.50 to 3.65 no
make it stable.

This basiscally means my Barton XP2000+ is performing to XP3200+ spec!
I love AMD.

I found the burnBX (from the cpuburn suite) was the first to fail.
Indicatiing the southbridge was the first component to flake out.

I did manage to push to 188 FSB but I started to get the kind of
instability you described.

At 176 it is rock solid reliable : I have been recompiling my complete
Gentoo Linux system over the last couple of weeks , This means 4 to 5
hrs solid 100% CPU usage and it has not flinched. (this load runs it
at 51C with room temp around 13 or 14 C)

BurnBX and burnP6 will do thier worst and get it to 54C .

This is perfectly safe (until the summer!)
