Loss of stability

[gasdoctor]

Hi,

A couple of bits of help needed.

I O/C my p4 4 months ago to:

Cpu: Intel Pentium 4 CPU 2.80GHz (Northwood)
Cpu Speed: 3.5GHZ
fsb:dram 5:4 (ddr 400)
corsair pc3200 1gb (512 dual channel)
MSI neo 2 mobo
memory voltage 2.6
meory timings (default) (2.4.4.4.8 as listed in cpu-z)
Vcore: 1.6
Cooling: Artic freezer 4
Room Temp: 23
Idle Temp: 36°C
Loaded Temp: 52 -56°C (48-50°C with case side off)

Ran prime 95 for 8hrs without error

Ive now changed my radeon 9800 pro for a 7600GT (agp)

Since this Ive started to get lockups in ww2 online, so I ran prime 95, which failed after 2 mins. The temps were about 60°C- 63

So Ive reduced my clock to 3.3 and Vcore to 1.575, this now runs prime for 8 hrs without error, temps about 60°C


So is this overheating (my old stock cooling ran the cpu at 70deg+)?

Or more worrying symptoms of sudden norwood death syndrome.

Or something else?

Cheers for your advice,

Edit: just ran 3D 05 and got a higher mark, using 92.91 driver though.

1.6vcore shouldn't be enough to cause northwood sudden death...

If your motherboard is i865 or 875 with PAT based then you will most likely see your best performance at between 200 and 220MHz FSB - higher clocks tend to result in PAT being disabled and the extra CPU MHz doesn't make up the performance difference.

Thats interesting, but excuse my ignorance but what is PAT?

The board is a MSI-6758 ATX / 875P Neo

Another question, whats the best CPU I can put in this board, in regards to performance when overclocked?

Should I put a prescott in, if I can find one?

What would be best value?

Cheers

i am sure prescott's did'nt come in till the later 775 sockets (someone correct me if i am wrong) but you can get up to a 3.4Ghz socket 478
