problems with KT600 and XP3200+ 400 Mhz

[Tommy]

Hello,

I have a gigabyte GA-7VT600 1394 with KT600. This motherboard has worked
just fine with the AMD Athlon XP2200+ for months...
I upgraded to XP 3200+ 400Mhz FSB and the machine became really really
unstable. The cpu was around 50-55 degrees centigrade so, ok.
I upgraded the bios to the latest version, F7, and still problems.

As a result I decided to return the processor and ask for another one. I
received the new one a few days ago and... I still have the same problem:
the machine sometimes halts: the screen becomes black and nothing would
bring the machine alive (you have to press reset).

I tried to increase/decrease the voltage, tried to have the DDR400 memory at
333 and 266, nothing, I cannot get rid of the problem.

Does anyone know what it could be? How can it be solved? Has anyone had the
same problem?

Thanks in advance,

Tommy

What PSU? XP2200 is 50W, core current 39A. XP3200 is 60W, core current
46A. Memory at 400MHz uses more power than at 333MHz. Increasing voltage is
even more strain on PSU. Could be dodgy memory. If you have more than one
module, try removing some.

Go into the BIOS and load failsafe / default settings for all settings.

This normally helps - you can then slowly increase FSB, etc.

slowly increase FSB? I do not want to overclock it. The FSB is 400 Mhz and I
wish it worked at that speed.... also because with my motherboard I can
select (with a hardware pin) 200 Mhz or auto (400), so... I cannot even try
266 o 333 (at 333 it would be a 2500+).

I have 350W PSU.
With the 2200+ I have had up to 3 hard-disks, now I only have 1.
With the 2200+ I was having DDR400, now, to try, i have put my DDR down to
266.

So, the problem might be the PSU, but I would not say so.

Thanks,

Tommy

XP2200 has FSB 133 (266). How did you set memory to DDR400? If your Mobo
does not hav async setting, the memory was running at 266. Either your Mobo
has a fault at 400 or the memory is failing at 400, but OK at 266. I once
had PC133 module which worked at 100, but int crashed at 133, had to be
exchanged.

I'm not suggesting for one second that you overclock.

What I'm saying is start at 100MHz. Then try different settings at
100MHZ.

Then go to 133MHz. Ditto.

And so on, until you get your proper FSB speed.

Yeah, at 100 Mhz it works, but I paid for a 3200+ not for a 1100Mhz !

That further implies there is a simple problem with the BIOS settings.

Frustrating, I know - but also check to see if there are any relevant
jumpers on the board that need changing.

Also check memory, etc.

the bios is so simple that there are not many options there.

jumpers on the board that need changing.

There is only one jumper: AUTO or 100 Mhz bus.
At 100 Mhz it goes at 1100 Mhz, on auto it goes at 200 (400 FSB) and it
goes, as expected at 2200 Mhz (3200+), but it is unstable.

Also check memory, etc.

Memory is fine, has worked at 400Mhz for ages and it is corsair brand.

Thanks for helping me.
