2.6GHz CPU (2653-R9U) chipset bottlenecked?

[chuckenheimer]

I wanted to upgrade the CPU but wanted to know beforehand if the throughput is chipset bottled-necked?

I don't quite understand what you mean by bottle-necked...but this upgrade has been done quite a few times, and it does result in improved performance on A3x units.

It also results in a significantly hotter machine, at least in my experience.

Log jam. Choke point. Data strangle-hold. Too much information is trying to both leave and get to the CPU for processing. Even thought the CPU is capable of processing more of the information than is being passed, it has to slow down and do empty cycles because the chipset(s) cannot move the data through.

The same chipset has been used on T30 which IBM offered with a 2.4 CPU at the time. I doubt that you'll run into issues that you are concerned about.

I've chosen cool over fast, but I'm sure that we would've heard something about this from people who had made the opposite choice, especially from founding fathers of this forum like JHEM who to the best of my belief still uses his A31p with 2.6 on a daily basis.
