I've disassembled my tuner and found out that this device only have 128MB (2x64MB) of RAM, not 256 as says in manual/tech spec part. It have 2 chips of samsung's K4T1G164QF-BCE7
Also linux TOP command shows 128MB of ram, and script of meminfo in web interface.
Can anyone give some feedback or facts that only mine [maybe i have clone's clone :DD] is 128MB? :)
