I just overclocked my 1.6ghz willmatte cpu to 1.85ghz and its on stock cooling and stock voltage (1.70) and i am currently using the heat test on prime 95 and it is up to 51degrees celcius i was wondering if this is ok and if i could push it further
hmm.. if you were lucky with that core (I used to have a willamette too, a 1.7Ghz one and I got it up to 2.25Ghz) you may be able to get to 2.15Ghz. Try upping the vcore and buying a better HSF... those are your best shots.
My Wilamette always ran on the hot side, I'd push 65C with the stock sink and stock clocks, so if you're really wanting to do some overclocking it, you should consider a new heatsink. I used a volcano 7+ on mine and it would top out around 40C load, so you might want to consider the Spark 7 (samething) or a Volcano 12+.
The error given out just means that while running the tests, the results of a given operation on the processor didn't meet up with what it should be, basically meaning the overclock was unstable. No damage would be done, you might just get crashes in games and such. You usually counter Prime95 errors by increasing the core voltage, but doing so will generate more heat.
