How do I subdivide part of model while keeping or with possibility to restore UV's.

I have the following problem.

I have a model with UV and nice high res texture.
I now want to get parts of the model subdivided so I can add more detail.

When subdividing just a part of the model it seems as a model lose the UV:s or rather they get corrupted as the surface get’s covered with tiny small squares with the content of the texture.

My idea was to subdivide the model so many times that the polypaint can hold the details from the texture.
Subdivide the parts that I want more polygons in and then UV map and create a new texture from the polypaint.

I can however not subdivide my model anymore because I have reached the limits in Mem > Max Polygons and it seems that I cant set it above 80 despite having lots of RAM.

I’s there any way to allow more polygons?

Or…
Is there possibly a way to subdivide parts of the model without loosing the UVs or to project UVs back.

I tried to make a copy of the subtool, subdivide parts of the copy and then use Project All in order to project UVs from original to subdivided subtool.
But Project All don’t seem to project the UV’s.

Any idea how to solv this.
