| Component | Specification | Implication for Custom ROMs | |-----------|---------------|------------------------------| | SoC | Intel Atom x3-C3230 (64-bit x86) | Requires x86 Android builds; no ARM native execution | | GPU | Mali-450 MP4 (ARM IP licensed by Intel) | Proprietary blob drivers needed for OpenGL ES | | RAM | 2 GB LPDDR3 | Limited memory for modern Android (Go edition recommended) | | Storage | 16/32 GB eMMC | Repartitioning risky due to Intel GPT layout | | Display | 1280x800 IPS | No high-DPI scaling issues |

Before you proceed with any modification, weigh the high risk against the modest reward. Make sure you have the correct drivers, the right files, and a lot of patience. And if you're successful, you'll have achieved something that very few Z300c owners have: a clean, streamlined version of a classic tablet, just as Asus should have made it.
