More on CPU specs of the ReadyNAS Pro

Hi,

One thing just to note, in the 'new' Pro 6 (RNDP6000-200) the stock RAM is actually 1x1GB Apacer PC2-6400 (75.073B4.G00). An upgrade to faster RAM you can do is PC2-8500, but because of the stock Pentium D E5300's 800MHz FSB it'll slow down to PC2-6400 speeds unless you stick in one of the 1066MHz FSB CPUs.

OK, In my case the stock memory is slower.

Perhaps those people here using CPU's that are still 65W TDP like stock but are running at 1066MHz FSB (e.g. Core 2 Duo E6700 & E7400) could clarify it they have noticed any increased temperature?

I'm one. And I can confirm that (all other parameters being equal) chipset temperature has varied up to to 2º C for me just by changing from one memory type/size to another.

There is a simple way to ensure that the chipset remains cool, however. Simply crank up the CPU fan RPM. Since the chipset heatsink is right next to the CPU heatsink, a high airflow on the CPU will produce airflow on the chipset and cool it accordingly. I have seen temperature drops of up to 10 ºC on the chipset just by forcing high RPMs ( > 3000 RPM) on the CPU fan. However, this is only acceptable for people that do not have to hear the racket made by the Readynas in these conditions.

With regards to heat from RAM, I'd guess that using RAM without bulky heat spreaders would be better as that'll keep any heat contained within the RAM (whereas heat spreader models would radiate the heat to the surrounding air).

I don't think this will help much. Chipset heating is related to RAM speed, but mostly from heat generated on the chipset itself by running faster and hotter. Ambient temperature is mostly a result of total energy contribution (component heat) vs. the amount of air moved by the fans. Heatsinks only help in reaching equilibrium faster, but they won't make air temperature lower or higher.
