Has the RRoD problem been solved? It's too early to tell, but someone over at AnandTech believes it's a good probability w/ Microsoft's new internal board, code-named "Jasper".

In short, the new Xbox 360 "Jasper" features a 65nm CPU, and a 65nm GPU. This, in contrast to the 90nm CPU/GPU found in Xenon/Zephyr units, and a 65nm CPU paired w/ an 80nm GPU found in Falcons.
What this means for us? A quieter system, lower power draw, cooler temps, and less stress on the solder joints that had a tendency to break down, causing the unrecoverable hardware failures, known as the RRoD, which, as most of us already know, has plagued Xbox 360s since they launched.
Now for the information you really want, and probably what drew you to this article in the first place. How to spot a Jasper-equipped 360 in the wild?! There are a few ways to determine that you PROBABLY have a Jasper, such as Lot # and Manufacture Date, but the sure-fire way is simple, and doesn't even require you to open the box. Microsoft included a side window in the retail box that allows clerks to scan the serial number when selling a 360. Look in this window, and search for 12.1A next to the 12V power requirement. It'll be on the left, and may be hidden at first, but try shifting the box around a bit, or even poke a finger in the window to shift things around. You may only see the 12.1A, but that's enough. 12.1A on the 12V rail means it has the 65nm GPU/CPU die, i.e. Jasper. FYI, it'll actually read "12,1" (comma instead of period). 14,2 = Falcon/Opus, and 16,5 = Xenon/Zephyr.
