Memory speed is limitation of the motherboard and is not related to the price of PC. The XPS 8950 sales page clearly states that the 4800MHz OEM memory will run at 4400MHz and 3600MHz. So you were made aware of this limitiation when you bought it.[IMAGE] The online XPS 8950 Setup and Specifications PDF page 14 clearly shows the same data =[IMAGE] If you're looking for more options with RAM configuration, you should have looked into a custom PC where you can choose specific motherboard that will support the configuration you're looking for.
My new XPS 8950 has the DDR5 ram which is made to be run at 4800MHz, downgraded to 4400MHz at 64GB and downgraded to 3600MHz for 128GB. There is a 12th Gen i9 compatibility problem with DDR5. Will this be only a temporary condition? I want to have the full 4800MHz capability in this very expensive PC at some point. If Dell answers, please give a clear and concise answer.
