Different 5-char Intel "product codes" and different TDP specs

A friend has built a system around a Presler CPU, and complains that it runs "hot, hot, hot!!" despite his application of ThermalRight SI-120 cooler.

I myself am still ruminating about "AMD vs Intel," although the advice seems to lean toward the former, and it will be a "first" for me.

But looking into my friend's disenchantment, I decided to visit the INtel site for product specs, looking for that "Table 5-1" common to all of their processor spec sheets.

There seem to be two different instances of the Pentium D 930, 940 and 950 Presler cores (I assume the Presler is represented in the "900" series.) One instance -- for each model -- shows a TDP value of 130W, while the other instance is rated at 95W.

Is this a matter of different production codes, or some refinement of the CPU manufacturing process with different production series? I seem to recall similar differences with the Northwood and Prescott CPUs.

If so, which five-character product code(s) would match the CPUs with a lower thermal power?
 
The newer "C1" steppings are the 95 watt, the older ones are 130watt. My 950 is an older stepping and it gets very hard to cool above 5ghz.
 
Yep boshuter has it right. However, it definatly shouldn't be running hot, I don't hit much more than 50c at 3.4ghz on the stock heatsink with my 920. The 9xx series runs significantly cooler than the 8xx series.

EDIT: P.S. doesn't look like the proccessor spec finder has been updated with C1 revision CPU's yet.

I haven't caught up on the specs for Conroe yet. Will it continue with the same socket-design -- LGA775?

It will use LGA775, but won't work with all LGA775 motherboards. There are some newer revisions of current motherboards that should have the correct VRM for conroe, that will just need a bios update.
