The original Xbox shipped with 64MB of RAM, which was quite a lot for its time in 2001 but seems small by modern standards. A modder called Prehis2oricman has quadrupled the amount of available RAM to 256MB using a custom RAM module that consists of two parts: a RAM chip and an interposer allowing use of all eight memory slots including those typically empty on the console’s motherboard.
This modification was achieved through months of reverse engineering, hardware engineering, software hacking, and perseverance. However, there’s little reason to install this mod currently as existing applications don’t utilize it. The potential for new BIOS updates that unlock additional features could change the situation in the future.
Do you think modifying console hardware like the Xbox to quadruple its original RAM is worth pursuing, considering the current state of software support?
To my knowledge the biggest benefit for this mod was emulation on the Xbox getting a performance boost. In most cases there are far better platforms to run those emulators on now.
I vaguely recall there being an uplift in fps on some titles - but in general it was a cool thing that had limited uses.
Well, we won’t know until people try this out, and make modifications to what’s needed, but the creator himself says that this mod is essentially pointless, as no homebrew uses this much ram, and most definitely no games do. This is a really awesome proof of concept though
