hi, i have motherboard msi fm2-a55m-e33 wich can run 1866mhz ram. I have 4gb cl9 nanya elixir ram 1600mhz overclocked to 1866mhz. I overclocked cpu to 4,6GHz in turbo mode and apu engine to a 1013MHz. Temperatures are good. In bios idle 23 C and after running prime95 full load about 30 minutes i have 42 C. (I have cnps10x performance). I want to ask if i add second 4 gb ram will i have better perfomance? Now i have about 900 in 3Dmark 2011. And below 800 not oc. I saw people in stock setting have 1300 in 3dmark 2011 running even 4gb ram.

Is your RAM 2x2GB or 1x4GB? If it's only one stick, then it's crippled by the single channel memory. Get another stick.

its only one stick, so i get performance boost when it will be dual channel memmory? And second question, if i add second stick do my apu size memmory will increase? I was reading there should be option in bios to increase that but i dont have it.

Yes, adding a second stick will double memory bandwidth, which will boost the GPU score.

And yes, you'll get the extra size. You don't need to set anything in BIOS.

It was my system windows slowing down pc, i reinstalled it, now overclocked to a 4600Mhz in turbo and apu core to 950MHz i have 1250 point in 3d mark11. So its about 300 points more on the same hardware. I will buy another stick and post results at the same settings.

dont expect huge performance increase going form single-channel to dual channel.
It has been proven that there are little to no performance increase.
