|It would be much cheaper to replace the motherboard with one based on one of the AMD 800 series chipsets, then overclock the heck out of the Black Edition CPU. Afterall, that's what the "Black Edition" is all about.|
All I can tell you about upgrading the CPU is what's posted at the HP website:
"Processor upgrade information
•This motherboard supports only AM3 processors
•Memory support is limited to DDR3 modules only.
•Split power planes allow separate power management for CPU and integrated memory controller for improved power savings.
•Supports the following processors:
◦AMD Phenom II X4 9xx/9xxe/8xx Quad-Core (Deneb)
◦AMD Phenom II X3 7xx/7xxe Triple-Core (Heka)
◦AMD Phenom II X2 5xx (Callisto)
◦AMD Athlon II X4 6xx/6xxe (Propus)
◦AMD Athlon II X3 4xx/4xxe (Rana)
◦AMD Athlon II X2 2xx/2xxe (Regor)"
BTW, when you called HP tech support, did you make it clear to them that you have the Black Edition? Also, did you update the power supply in your system? Your new CPU is rated at 125W, the stock HP power supply is only 250W. The Athlon II x2 240e is an energy efficient CPU that only requires 45W, that's why they installed such a low wattage PSU.
