Lenovo G700 RAM upgrade problems



I wanted to upgrade my laptop from 8 GB RAM (2*4 GB) to 16 GB RAM (2*8 GB). My computer supports max. 16GB RAM. My computer datils befor the upgrade (I can add adittional inforamtion if needed):

     Operating System: Windows 10 Pro 64-bit
     CPU: Intel Core i5 3230M @ 2.60GHz 62 °C, Ivy Bridge 22nm Technology
     RAM: 8,00GB Dual-Channel DDR3 @ 798MHz (11-11-11-28)
    Motherboard: LENOVO G700 (U3E1)


I bought 2 x 8GB DDR3 1600 SODIMM 1.35 V (CT102454BF1505.M16FED) cruical units.


When replacing them I get only a black screen, no windows or BIOS or anything. I tried all the variations and found out, that if I use one old 4GB unit and one new 8 GB unit it works and I get 12GB ram, details:

     MemoryType: DDR3
     Size: 12288 MBytes
     Channels # Dual
     DRAM Frequency: 798.7 MHz
     CAS# Latency (CL) 11 clocks
     RAS# to CAS# Delay (tRCD) 11 clocks
     RAS# Precharge (tRP) 11 clocks
    Cycle Time (tRAS) 28 clocks
    Command Rate (CR) 1T


I looke up everything, tried updating BIOS, cheked the settings and now in the dark, I can't fine the solution. A weird thing that occured is before it said (2*4GB):

Total memory slots 2
Used memory slots 2

Now it says (4GB+8GB) - I have only 2 memory slots:

Total memory slots 4
Used memory slots 2
Free memory slots 2


Does anyone have an Idea wha's going on?

Re: Lenovo G700 RAM upgrade problems

@bvasli Thank you for contacting us today. I am sorry to hear you've had issues with your RAM and I apologize for the late reply. Will you please verify the part number on the memory module? The part number you listed isn't a part number we sell, so I wanted to check to see if that is the actual part number you see on the module. If it's easier for you, you may take a picture of the label and post it. 


This will help us verify if the memory you have is compatible or not. Thanks again.
