I had just purchased this "system pull" CPU used off of ebay and so far, it works beautifully, except for the fact it won't overclock even a bit!
If I push the fsb from its stock speed of 1066 (leaving the ram at 800, unlinked, it won't overclock either) to 1200 or even 1100, it barely makes it past the windows 7 boot animation before having an omnious-looking blue screen pop up that says "hardware malfunction"...
I decided to increase the voltage to 1.3v to see if that would help, but it didn't. I then tried 1.4 with no success. Does the multiplier factor into this situation at all? It's at 9x (as high as it can go), but it can also do 8x, 7x, and 6x.
By the way, it runs at stock, as far as I can tell, completely stable at stock clocks and voltages.
