Video card upgrade?

Question

Video cards

Good day to all, there is a video card “nvidia gtx 570 MSI”
It has a bandwidth of 152GB, a 320bit bus, a core frequency of 7**
I would like to increase both memory and bandwidth. Is it possible to replace the memory chips with this?
For example, now there is a Samsung memory with a frequency of 3800. If you replace it with any other one with a frequency of + - 8000, will the video core pull it out or will only the volume increase.
And if everything is OK, then I understand that it will be necessary to reflash the BIOS.
That I don’t think correctly, because somehow it seems easy, but it doesn’t happen easy in this life!)

Answer 1

The only upgrade of the video card (hardware) that makes sense and is available is the replacement of the cooling system with a liquid one (for Ali, prices are about 4-5 tr, if assembled in parts) and extreme overclocking.
Otherwise, just a complete replacement.
What to replace it with is a million-dollar question, and the answer depends on your tasks, or rather, what architecture the software is optimized for, usually it is a choice between amd / nvidia. The choice of what is more critical - the number of shader processors or the frequency of RAM (and its amount, but these are quite narrow tasks), only tests can answer for sure, but unfortunately nothing can be done empirically.

Answer 2

If you want "experiments" you can safely change RAM, bios, GPU (choose what you need).
The best option is to replace the video card with the right one (depending on your tasks)
