So I bought 3 XBOX's from my friend. I bought a standard one, I bought one with a 1 GHz CPU mod and one with a 1.4 GHz CPU mod. Is there a way or maybe an app in the softmods that can tell me what my CPU is? I have mixed the three up when moving and I would like to know which is which. I know certain games won't play when running on CPU upgraded systems. But since I have 2 separate CPU mods, I can't tell which system has which CPU upgrade. SOLVED! Solution is in the XBMC. If you click in on R3 you will be presented with some options. On the left of the 4 options is an icon shaped like a lower case i. It's called System Info. Choose it. On the next screen you will have several options on the far left. Go to the very bottom to where it says Hardware and choose it. Your screen will now populate with several different pieces of hardware information. What you're looking for is the 3rd piece of information in the list, the CPU speed. I found my 1.4Ghz was running at about 1399.28Mhz and my 1Ghz was running at 998.10Mhz. Fun stuff!
