I currently have a laptop with an Intel core i5 3210m and 6GB of 800Mhz RAM. I was wondering if buying an 8GB 1600Mhz kit would improve the performance of the GPU and therefore increase FPS in games. I heard somewhere that RAM frequency does play a part with integrated GPU's but because of the lack of information when I googled my question I wasn't sure, so I came here.

More about : ram frequency affect integrated gpu performance

Sure it do help. I did just OC my memory to 1866MHz and some tests show 10% better performance. But is it going to work with laptop?
Do that mobo uspport faster memory than 800MHz?
Can u OC memory now? Try first hit 1000MHz with 800MHz memory?

Yes, RAM frequency is actually quite important for the performance of an integrated GPU. GPUs need a lot of memory bandwidth, which is why most dedicated graphics cards use their own high-bandwidth memory type (GDDR5). Integrated GPUs are stuck with lower-bandwidth DDR3, so the higher the frequency the better.

However, your memory is already DDR3-1600. You'd have to buy something faster to see any benefit, and your motherboard may not support that.

Due to the limitations of my laptops BIOS I can't OC my RAM.

I currently have 6GB of 800Mhz RAM, would upgrading to an 8GB kit with 1600Mhz frequency help? that was my question :)

If your RAM is really 800 MHz then that's DDR3-1600 (due to the Double Data Rate).

Double Data Rate? Could you explain what that is please? I've never heard of it XD

It just means that the memory transfers information twice per clock cycle. DDR, DDR2, and DDR3 are all named after this (Double Data Rate = DDR). So DDR3-1600 runs at 800 MHz.

But there is some confusion about how manufacturers etc. label this, so you could check with a program like CPU-Z to confirm what clocks your memory runs at.

CPU-Z says that I'm running at 800Mhz

Then your memory is at 1600MHz.
Just shows 800 x 2

My CPU Z shows now 933 x 2 = 1866

So there's no point upgrading to a pair of these then?

No if you are looking more speed.
