kinda answered your own question didn't you? Or do you mean to make it more stable?

Unless I'm missing something, all of the 650 series P4s (as listed <a href="http://processorfinder.intel.com/List.aspx?ProcFam=483&sSpec=&OrdCode=" target="_blank">here</a>) have a max reccomended temp of ~67 degrees C. Why would you limit it to 50 degrees C born2killU?<br />
<br />
Again, I don't know much about OCing P4s (I'm a Core 2 Duo kinda guy myself).. but i was just curious.

50C isnt a limit as such, but those 65c guidlines are supposed to be for stock voltage<br />
<br />
more voltage=more heat=more possiblilty of damaging gateways=dead cpu

My old 650 did 4.0ghz easy on air with stock volts. I tried to push it to 4.20ghz but the HSF was not helping and I never tested it with a Tuniq Tower 120 but it did for sure 4.0ghz with ease. <br />
<br />
I'd say give it a shot at 236x17 and it should work, don't change the Vcore though.
