[XBox Original Ram Upgrade]

When doing the 128 mb mod i first place the chips in place the using smd rework hot air i get them tacked down. Then i go over each pin with a soldering iron. then i clean it up by going over them with hot air again to make the solder look nice and clean.  Im sure you can get it correct with just the hot air , but so far i have not had luck with that.  I need to get better it seems. but that works for me.

Prerelease/beta games is my main reason to have the 128mb mod.

[Benefits of Mod Chip over TSOP?]

From personal experience with flashing a tsop with a bad image, a modchip is much safer to test bios images on.  If you somehow brick a modchip (unlikely) you can just replace it.  with a bad tsop flash you can swap the tsop from another console of the same revision.

[Which Version of the Original Xbox Is the Best? 1.0, 1.2, 1.3, 1.4, 1.5 or 1.6?]

I personally like the 1.0 It has a fan on the heatsink and the TSOP is 1024kb.  I have done the 128mb mod on it with much success.
