I installed the Phase1 and Phase2 KT7 Voltage mods.
I broke into 900 Mhz at a core voltage of 2.10 and 950 Mhz at a core voltage of 2.20V.
This is definitely way outside the "Sweet Zone" for this particular CPU, but it runs.
Even with the MC-462A running full tilt, the core temperature rises from 21C at idle to 40C running Prime95 torture. Beau Coup watts here. Consider that Radiate runs out at 2.05V yielding 70W at 950 Mhz. Heaven only knows what I'm developing at 2.2V! To add yet another concern to the situation, my no-name 300W PSU +5V is now visibly starting to collapse. It is down to 4.88V with the core voltage at 2.2V and running Prime95 torture. It bounces back to 5.15V at idle. I am confident I can hit 10x100 by upping the core voltage to 2.3V, but it will probably kill the PSU over time.
So, now I find myself at a junction in the road. Three forks ultimately lead to pulling my wallet out of my pocket, yet again.
I can choose to:
Buy an Enermax higher wattage PSU, run this poor 650 Mhz T-bird in the red zone, deal with the elevated temps and possibly destroy it and portions of my mainboard over time. But, I can brag about OC'ing a 650 T-bird at 10x100.
I can buy a higher speed T-bird, for about the same price as the new PSU and run it in the sweet zone, say an 800 or 850 at 10x100. Shouldn't take nearly as much a raise in Vcore. Relegate my 650 T-bird to "backup status", next to my 600 Duron or sell it.
I can still brag about the OC, but not as much.
I can buy a KT133A based mainboard and run the 650 T-bird at some weenie cop-out like 7.5x133 ;-) and brag to the uninitiated about my 1G OC'ing exploits.
I can go back to my Trusty Duron which runs 10x100 effortlessly and shelve or sell the T-bird. Big cop-out!
Maybe take it up to 10.5 or 11x100 now that I have the voltage mod in.
The combination of choices are limitless, but take a severe drop in popularity from this point on.
So, I'll ruminate on this situation for the moment and ponder the $59.00 I spent on the 650 T-bird as an educational expense :-)
