Hey guys, i need to know how to overclock my gpu and what's my gpu limits?and does the mobo affect gpu overclocking(ASUS MAXIMUS VII RANGER)?can i raise the vram?and can i overclock without raising the voltage?or what's the safe voltage to raise?another question does My memory benefit the vram?

Well you start by increasing the clock slowly, doing a test to see if it runs stable, eg. maybe playing a gpu heavy game in 2min, when the game starts crashing then you should add a little bit of voltage, then continue on the clock.
Im not sure about the vram overclock, though i think you're able to go over 1650mhz atleast. RAM doesn't really affect VRAM at all, they're both memory for two different components (CPU & GPU), only reason some might say this is because APU's (CPU's with an integrated GPU in the chip) uses the RAM as VRAM for the GPU, that's a situation where fast RAM helps, but not with dedicated gpus at all.
Don't think the mobo have any affect on your GPU clocks, the GPU is carrying all it's components by itself and only...

Don't think the mobo have any affect on your GPU clocks, the GPU is carrying all it's components by itself and only sends the data to the mobo, the only mobo thing to limit a gpu would be the PCI-E slot, though as long as you have a compatible PCI-E 2.0 or 3.0 slot, the difference is going to be under 1%, saw a review in this and they used decimals to count the difference in FPS.
Your board have PCI-E 3.0 x16, which is the fastest & the common PCI-E you'll get in any newer board. ;)


Hope this helps
