Hi Toms Forum,

I have looked around a fair amount looking for the answer to this question, have never seen it adequately answered (in my opinion).

The question is this: What gains can be had from overclocking the Memory clock of your GPU?

Increasing the core clock directly affects raw performance and FPS, but I haven't seen a good answer as to what benefits come from increasing the memory clock (aside from a higher 3Dmark score)

Answers and insights would be very much appreciated.

Thanks in advance!

Memory overclocking helps on cards with low memory bandwidth, and with games with a lot of post-processing/textures/filters like AA that are VRAM intensive.

Does anyone know of an article that benchmarks VRAM clocks compared with Core clocks?

I am looking for a more quantitative idea of how much affect VRAM Frequency has compared to Core clock frequency.

Generally it's better to focus on core first then memory, but overclocking the memory does help. I think Tom's had an article on this a while ago, can't find it though.

To add to this question without making a new thread is will overclocking your memory higher decrease how far you can overclock your coreclock? For example my 7850 2GB will do 1050mhz core / 1300mhz memory without any voltage increase, if I lowered memory to 1100mhz could I do 1100mhz on core with the stock voltage?

Just a curious question :)
