Differences in core temp - is this ok?

OK cool, what would cause the machine to reset itself without warning?
I have ordered a new cooler as currently I am using the stock unit that came with the processor. I am also upgrading the PSU to a Corsair 520 from the 350W unit that came with my case.

I think the prob is from the psu cos 350W seems a little too low for that cpu.. also especially since it came with the case it probabbly ist not of the highest quality so it is causing the voltages to fluctuate so much.. 1.4V @ 2.8 Ghz is a rather high voltage to be giving th cpu unecessarily..
Get a good PSU and lower the voltages ..
70C is rather hig for a cpu especially if those temps are on idle!! therfore that may have caused the restart

Those are the temps with Orthos running cpu and mem tests.
I will turn the FSB back upto 401MHz and post up a speedfan reading.
Should I configure my northbridge voltage manually or leave it on auto?
FYI: I am running 4x1gb XMS2 memory in an Asus P5K on WinXP SP2
My temps on a A64 4200 x2 idle at around 28 ,29 (fsb:245x11, 1.36v, 2699mhz) and during games etc they increase to about 50 ,54. But when running Orthos they can get to 50, 60 at times, this seems like a very big difference in temps between the two cores which is worrying me slightly, although as I said during games etc they don't get as high or as far apart. I'm using core temp but asus probe gives a much lower temp (45c) but I'm thinking thats the socket temp?
Remember that different programs read different things (I can't quite remember why).
What you should be interested in is the core temperatures, and for that I'd stick with Core Temp or the Intel Thermal Analysis Tool (they should give you identical values, just so you sure).
Can't really compare your new temps as they are at idle. Make sure you post temps with Orthos or smilar running (for 30 mins or so) to stress them 100%.
As others mentioned, your original voltage seemed a bit high for the overclock. Was it the lowest you could get it stable at?
70degC is a bit high for that clockspeed, but probably not supprising as your using a stock cooler. When you install the new one make sure to clean the old paste off properly and use the right ammount of new stuff. Makes all the difference.

I used 1.4v as I read this to be a good voltage for stable clocking, should I decrease it at this core speed then?
Standard my core runs 2.33GHz, clocked I am running approx 2.8GHz.
With Orthos running for an hour my readings with core temp are 69 to 71, this is with a standard cooler.
I set my Northbridge voltage to 1.4v and it ran all night without crashing at 401FSB

What you've got to understand is that Voltage and FSB are connected. The faster you run your chip the more power its going to need. At the same time the more power you put through your chip the more heat its going to give off. Its not right to pick one voltage and say 'this is good for overclocking', as it depends on your clockspeed. I'm not sure you can even give voltage guides for specific chips and FSB speeds, as slight differences in the manufacturing process will make every batch of chips unique.
Overclocking a chip is a bit of a balancing act between voltage and FSB, and you need to tweak both to get the most out of it.
Try turning the voltage down step-by-step, and testing in Orthos each time. If the computer locks up or becomes unstable you know you've found your lowest stable voltage. Set it back to the last working value and do some longer testing in Orthos to be sure. This should help your temps a bit, and maybe give you some more headway for FSB overclocking.
