what does overclocking gpu memory do?

i have a gtx 1060 and the memory is clocked at 4000MHZ, what would overclocking my memory do?

increase overall responsiveness of the GPU. You can google the question and get a better answer than i can give though

oh ok thank you

I would try to keep the ratio of my memory and core clock the same on a GPU if you intend on overclocking.

 

As far as what it actually does, it's similar to RAM where the speed increases the rate data flows through the memory.  vRAM works the same, and a higher clock decreases the time it takes for data to flow through the vRAM (opposed to actual amount that's determined by the size, ex. 4gb vRAM).  Certain workloads can benefit from either faster RAM or more RAM, but typically more RAM has a bigger advantage than faster RAM.

More fps.

Sometimes a little, sometimes a lot.

I've seen people get different results.

No harm in trying it, if you don't see a difference put it back to default.

It depends on the GPU architecture.

 

For Maxwell and Pascal, they do most of the work on local cache before committing the results to memory. This results in less usage of the memory pipes meaning a bump in memory speed beyond what's already there is probably not going to do very much for them. It may help, but at some point the actual memory bandwidth is going to exceed the throughput of the GPU. For AMD architectures, they need to do a lot of VRAM streaming so higher memory bandwidth helps them a lot more than with NVIDIA.

 

But if it's anything like CPUs, what the VRAM ships with probably provides the most benefit and is on the starting point where diminishing returns hits hard.

I got my 1060's VRAM running at 4500Mhz (9.2 Ghz actual) and it does boost performance by about 5-8%, add an increase to the boost clock and you should easily see over 10% performance increase.
