Also please don't install 6.3 Irix on your machine, it's a literal waste of time.  Everything that was anything runs on irix 6.5...that's just life.  It won't run faster, it won't be better, it will just suck more.

You really should stick to hardware.

6.3 was specifically for the O2. It's a single-CD install, it has some special features tailored to the O2, it works great on an O2. Most or all of the reasons you'd want to go to 6.5 are not valid these days. Here's a clue : I have actually had O2's with 6.3 and they work great. (As great as an O2 ever works, anyhow).

The reason to use it is, it's a very simple and easy install, meant for the O2, which a 6.5 install is not. It's limited to just what an O2 has, so you don't have to know what you are doing and dig through five CD's to pick and choose the parts you need or want.

The reason to not choose 6.3 is, it's older and has fewer bells and whistles and features that one might want if one were using the computer as a daily driver in the modern world. Given the unreliability of the O2, that would be tantamount to masochism

The O2 prom does not come up at anything over 60 hz. Whatever is going on with yours, it's not that. When Irix comes up it initializes X and that can be where you'd see a switch to a higher resolution / faster refresh but not before then. Sorry.

Please, go to techpubs. All this is covered clearly, from the horse's mouth, not hearsay and faded memories or stuff someone read somewhere online.
