Mac Mini 2009 RAM Problems

[josephdj94]

Hi

Having problems with my 2009 Mac Mini 2.26GHz Core 2 Duo. Just upgrading the computer with a 128GB SSD and upgrading the RAM from 4GB to 8GB.

I installed the new RAM and when trying to first boot the computer got the three beeping sounds indicating problems with the RAM seating. So I opened up the computer and re seated the RAM. I tried this several times but with no result. I put back in the original RAM and the computer booted up fine. So its not a problem with the slots.

The RAM I have purchased is Kingston KTA-MB1333K2/8G 8GB. Do I have a compatibility issue? Or could it be faulty RAM? I tried both sticks separately and still got the problem.

Many Thanks!

Mactracker app shows 1066mhz ram used in 2009 minis.

yeah here is a link for ram in that mini


http://www.amazon.com/PNY-PC3-8500-...KD3-1066/dp/B004DHK85I/ref=pd_sxp_grid_pt_2_1

also here is a firmware link for use of 8gb ram in that mini

but you will still need the pc3-8500 1066/1067 ram

you have pc3-10660 1333 ram


note that the 1066(right ram) looks a lot like the pc3-10660(wrong ram) Many people buy the ram you did and have your problem.
