Benefits of faster RAM on OC'd Intel HD Graphics 3000?

post #1 of 5
Thread Starter 
I'm in the process of building a new PC and wanted some more opinions regarding RAM. I plan on using just the Intel HD 3000 IGP without any dedicated card to play Starcraft 2. Reviews online seem to indicated that the i5 2500k + Intel HD 3000 can run it "okay" at low settings. but I'm hoping to try and improve that. An article on anandtech showed benefits from overclocking the IGP but also said that the main constraint was with memory bandwidth. Will getting more RAM, say 16GB benefit me more than 8GB? What about overclocking to 2200 Mhz vs. 1600?

Memory bandwidth is NOT the same as memory size.

Unlike AMD Llano, Intel HD Graphics don't scale that well with increasing memory frequency. If you haven't got your parts yet I highly recommend switch over to AMD Llano.

And don't spend more on premium memory. You'd be better off with a lower-midrange GPU instead.

u can determine the difference with benchmark programs such as PC Mark 7 score there's encoding test.
afaik the iGPU speed is the same as memory frequency.

It's not.

They can be, and usually are, set independently.
