GPU overclocking Core and Memory. Why oc the memory?

[Dr_Nooberious]

Hey all.

 

Ok, so I googled this question for quite some time now and I can't find a solid answer. Does overclocking the Graphics card memory helps with displaying an image? For example Black Ops 3.

 

I overclock my Giagbyte 750 Ti 2x Windforce OC edition with MSI Afterburner and I got and average of 1293MHz (+200 compared to stock) on the Core and 6652 (+625 compared to stock) on the VRAM.

 

Thanks for answering.

It helps achieving higher FPS. Thats simply it.

a gpu that is over clocked will get you more fps in games. if it is displaying a static image it wont make any difference

Can you give an example? like how the OC would effect gaming like Black Ops 3?

more fps...

i dont get what you don't understand

[Xaring]

You get more frames per second, you feel the game smoother, easier aiming, more tick rate, your PC says "im firing" more times each second, might give you a slight edge if your opponents PC is running at 30FPS (or on a console Kappa).

idk it would give you 5%ish more frames not too familiar with Black Ops 3

To all y'all who already answered trying to make him sound stupid he is asking about overclocking the memory on the card not the core

Ok, let me try this. How does OC'ing the memory give more frames? I understand why OC'ing the Core does give more frames.

 

Lol, thanks jjohnthedon1

No idea, BO3 is not a hard game to run, as they keep using the same old engine and assets, so id expect way over a 5% increase, 625 MHz is quite a bunch.

It still just gives you more FPS, same as core.

Was wondering the same.

But just increasing memory clock doesn't make big difference. At least not for me, so I don't realy OC memory clock at all

Basically it helps if ur card has low memory band width 

which will get used up if ur games is using lots of post processing 

 

so if ur memory bandwidth is you bottle neck in a game oc ur memory 

 

only way to test if memory is the bottle neck is to oc it and see if ur fps increases 

 

its like this it doesn't mater if ur not using all of it there is no differance but once u use all of the bandwidth up overclocking it will help boost ur fps back up

but normally most cards are set with the right amount of bandwidth for what there ment for

 

i find it more useful for Sli 

because u find ur self with double the power but only the same amount of memory 

[jjohnthedon1]

Also for the most part people actually lower there memory clock to achive higher core clocks if they are finding that they do not have a memory bandwidth issues 

[jjohnthedon1]

So in answer to ur original question ur 750ti I'll run out for core performance before using to much aa and other effects chockes ur card

Analogy time...!

 

Imagine a sushi bar, like the ones with a conveyor belt delivery system. On a GPU, the core would be like the chefs, and over clocking this would make sushi a lot faster.  "Great!" people will say, as this delivers more sushi right? Well... sort of. There would be an increased output of sushi... as long as the conveyor belt (memory) could keep up with the sushi being made. When there is too much sushi being made, the conveyor belt would become a bottleneck and would also have to be sped up.

 

This problem is also more noticeable on GPU with lower amounts or conveyor belt... I mean memory, and memory bandwidth.

 

TLDR: Low memory speed can bottleneck an overclocked core

If your card is getting memory bottlenecked it will.

For example:

Let's say your playing Black Ops 3.

The GPU is calculating what the next frame is. However, if the GPU needs information from the memory on, let's say, what the position of a player is, normally it could just calculate other stuff in the meantime. But if the position of the player is the ONLY thing it's waiting on, and it doesn't have anything else to do in the meantime, then it would just be waiting on the memory and idling in the meantime. In that case faster memory would make your GPU faster.

Hope that makes sense.

Thanks for all the answers! this gives me a better idea on what the OC'ing does for my GPU.

 

OK, two mores questions: 1) Does OC'ing the memory help with frame times and reduce display lag?

                                         2) In games like The Forest and 7 Days to Die, my GPU usage is pegged at 95+ and VRAM is 1.8+- GB used. Does OC'ing the VRAm help alleviate this problem. (My CPU is a I3-6100 @ 4.4GHZ with 8GB of DDR4 @ 1620MHZ) (the ram speed is slow because I OC'd the CPU with the base clock)

There a multitude of variables that affect frame times but memory will help but only if u have a memory bottleneck 

nice oc btw! 

Very impressed
