RAM Help

I dont know if its the RAM thats reducing FPS or what. I have 3/4 sticks occupying the DIMM, two of them are SK Hynix RAM of the same model 2x4GB and another is a random Samsung RAM which is also 4gb. I open CPU-z and it tells me that my RAM is being run in dual channel mode. Is that including the odd samsung stick?

Does your mother board support quad channel memory? What motherboard do you have?

Its a Dell Optiplex 990 and it does have 4 slots. Im not sure about quad channel because i only have 3 sticks

It might be the speed of the RAM, since the optiplex's that I have worked on only have DDR2 memory

Then it should be "fine". I think its that you have three sticks, try using 2 for a bit, to check stability

Can someone give me a more detailed answer please. I don't know if I should keep the odd stick in there or not

You cant use 1 or 3 sticks. Use 2 only. Make sure they are in the correct slots for the motherboard and you will be fine.

I see now, in more detail in CPU-Z, I am told that the 2x4 sticks are both running in dual channel and the odd stick is running in single channel. Will that affect performance?
