Thanks Lokki.... this verifies my findings that the 9.2.2 version of the system profiler is actually reading the cache size correctly (although it reports L3 as L2).
Even though I have setup many of these units for clients over the years, I always assumed the cache size on the Dual 1.25 and the Single 1.25 CPU versions of the 2003 MDD were the same... bad assumption... I just never looked closely enough and that is the reason I started the thread, to compare units that were stock... I own both single and Dual 1.25 units... but I do not think any are stock anymore (their SN#s and white labels don't match their configurations)... I Swapped so many CPUs in these units over the years that I was hoping people would post their findings on stock units... so, thanks
Interesting coincidence, the cache on your dual clocks exactly the same speed as a single that I posted @ 178
So... it is clear now we should update all references to state the the ultimate stock OS 9 unit would be the Dual 1.25 (so you get the 2 MB cache) and simply leave all multiprocessor support disabled (for stability). But the jury may be out since now we have more heat and more fan noise with the duals. Many DAW plugins and even some hosts (such as Cubase) crash with having the multiple CPU options enabled... so in the end you will have a single 1.25 with double the cache.... maybe the hard core Logic users can heavy test the Multi VS Single CPU scenario and post results... If there is a DAW program that runs stable with dual CPUs it would most likely be Logic.
I lastly want to note.... the reason I suggest the whole "1 GB MAX" instead of 1.5GB is that although Mac OS 9 supports a maximum of 1.5 GB of memory, it only supports a maximum of 1 GB allocated to a single application and I strongly believe that some of these programs do not respect that limit and go outside of the 1 GB limit and crash (just a theory), since I have definitely found bugs (in Cubase anyway) that only seem to crop up when the total memory is above 1 GB. To add to the confusion, Mactron allocates more than a 1 GB to Kompakt and it works great so... who knows ?
