I couldnt reply to the original thread so I created a new one to ask a follow up question. Neither can I PM or email the gent. Really apologize for duplicating threads.
Original Topic: »iMac Compatible CPUs
skeechan: With the QX9300 socketed into your iMac8,1 it would not boot up? Did you happen to buy other Socket P processors for another attempt?
Socket P processors I was looking at for my iMac7,1 are the ff:
2.53 GHz Core 2 Extreme QX9300
2.27 GHz Core 2 Quad Q9100
2.00 GHz Core 2 Quad Q9000
3.07 GHz Core 2 Extreme X9100
2.80 GHz Core 2 Extreme X9000
2.80 GHz Core 2 Extreme X7900 (confirmed)
2.60 GHz Core 2 Extreme X7800
3.07 GHz Core 2 Duo T9900
2.00 GHz Core 2 Duo T7300 (confirmed)
I chose Socket P's that are either extreme, quad core or exceed 3GHz. I did this to make the teardown worthwhile. May also install a 4TB Seagate Barracuda 7200.14 when it comes out as I project it to be as fast a 1TB WD VelociRaptor when it ships. 160+MB/s read/writes seems nice to have.
I would go SSD but the SATA port is 3Gb/s. Would have been nice if all the SATA ports were 6Gb/s but the standard was ratified middle of 2008 so 12 months too late for me.
iFixIT has my specific iMac fitted with a T7300 upgraded to a X7900. The TDP of the processors differ (35w vs 44w) but share the same FSB at 800MHz.
Could it be that the QX9300's FSB is too fast at 1066MHz or the TDP being 45w?
Anyway this is just a preventive maintenance question as I would probably be changing the HDD when it dies. May as well upgrade the processor when I swap out the dead HDD.
