I just saw the difference on samsung official the only difference is speed of vram,

I have issue with my 1050ti vram K4G80325FB-HC28 thinking of replacing with K4G80325FB-HC25 will it work ?

Do you have the tools and knowledge to de-solder memory from a GPU and attach new memory? Is that what you are trying to do?
Yes, i have a guy who have knowledge if replacing the chips but he is not sure about will replacing HC28 with HC 25 will work or not, we are trying to replace

As long as the interfaces between both are identical and they are properly connected, they should work. Given the age of the GPU and the risk of permanent damage, wouldn't it be better to just save your money and get another GPU?

I still could not understand do you mean both are same and can be used as a replacement for HC28 ?

What happens if there is a mishap....and the GPU is dead?? How much will you be saving by buying a new GPU instead?

It will not work hc25 is not the same as hc28 I have currently made that mistake or someone else made it (as I dont remember who changed this memory chip on this card or i bought it like that can't remember anymore), as I currently have a gtx980ti with both hc25 and hc28 that won't start, even though memory power rail is up and running and the gpu core voltage is present. The mats test for this card failed with strange errors when i tested it something like 32 bits is different than 8.

So my recommendation based on evidence, buy a "hc28" chip.

and NO it won't break the GPU as both have the same ball out scheme but the data side is different

have a look https://photos.app.goo.gl/2wWttRSd4MdVUs3M9

One more thing, both HC25 and HC28 actually have the same size the only noticeable difference from the specs according to samsung is the 8Gbs vs 7Gbs data rate speed. Which could also require some different memory clock rates as both have different data rates.

in theory the HC28 7Gbs is replaceable by HC25 8Gbs but not the other way,. But in practice it seems not.

Actually even in theory it won't work, if I get this right, the memory clock is tightly coupled with the data rate speed of the chip.
