I don't follow what you're saying but you need the high mem option in the kernel config like the link I gave you said. If it is not, than recompile kernel with the option, use genkernel, which is also posted in that link I gave you.
"you need the high mem option in the kernel config" -> Could you explain me howto do, because I tried the links but don't understand them. I'm a new with Sabayon and I wouldn't do any mistakes with my system.
Hi, The best option would be to opt for sabayon 64-bit which will by native support RAM ranging from 4 to 64 GB (am not sure about the upper limit) , but you need to have 64bit CPU which normally all CPU are nowadays thanks,
