Hi, 

I just bought 8GB sticks (2 sticks) of P Sector 5 DDR3 RAM sticks for my Dell OptiPlex 3010 SFF. Once i install it, power it up, i received error code 3-4 amber light. Nothing happen. I chaged different slots, yet still the same.

Once i install its old 4GB sticks it works normally. 

Any way or troubleshoot to fix above issue? 

Note: i bought new RAM.

Thanks,
