I just got a display model 3.2 ghz 5,1 model and upgraded the processor to a w3690, 48gb ram and a velocity X2 with a samsung 840 1TB. The only issue I am having is that when I press the power button the machine takes about 8-15 seconds for the boot chime to play and startup. I'm not sure if it was like this before I did the upgrades. I have tried doing a PRAM reset and smc reset but no go. Unless this is normal? Has anyone ran into this issue? Thanks for any insight.
