There is no question about the fact that 4- and 8-core classic MacPros should have a configuration with just 3 of4 RAM slots used ... So "3of4-slots-configuration is prferable, BUT:
I remember the argument why a 6-core or a 12-core MP would profit from 4of4-configuration:
The Xeons ar able to create a virtual 3rd core. To max that out, you need a sum of real hardre cores that you can divide by 3 so that any pair of the real existing cores can create and use a third one. if this is not the case, the 4th occupied slot will only brake instead of helping the system.
-----> could someone with a 12-core MBP help,us tomverify this?
Would be easy for him:
Just run a performance test with both configurations and report the result....
Imthinkmthis would be very interesting for a lot of people.
As for "as much RAM as possible is the best and not enough RAM in 3 slots is worse than enough RAM in 4 slots" :
i agree, having 32 GB of RaM since I purchased my MP with it (yes, I was really that naive and burned money because at that time this was horribly expensive...)
Last question:
Does it matter which of the 3 slots are used for RAM or not?
Thanks in advance
