Thank you for the response. I have after market RAM, I bought from Other World Computing; however this RAM has been in the computer for a while without problem, probably 6 months since last upgrade. I pulled each and re-seated them, then tried powering up with no luck. I even pulled one altogether and left the other set in and still no luck. Advice from here??? Mike
They have to be in pairs in 2006-2008.
Try one pair at a time. A1/A2 (and A1/B1 for 2008 3,1)
RAM fails. Marginal, defective, whatever. FBDIMMs are subject to heat, why there are those heat sinks.
And you really want to be running fans 400 rpm higher than base defaults with SmcFanControl 2.x
Try with just OWC and pull Apple also.
Run Memtest / Rember / Apple Hardware Test
