All that matters for most server admins is that RAM have matching ranks. A memory rank is, simply put, a block or area of data that is created using some or all the memory chips on a memory module. Controlling interleaved accesses like so is done by the memory controller. The performance gain that can be achieved is highly dependent on the application monate kennenlernen im kindergarten the memory speicher single rank dual rank ability to take advantage of open pages.
On dual rank versus single rank performance: In principle, memory ranking may be considered as on-module memory banking. All that matters for most server admins is that RAM have frauen in amerika kennenlernen ranks. I have this question too. Single Rank Memory is distinguished by the information that is displayed on the information sticker on the memory, Single Rank has a 1Rx on it, for example 1Rx4 or 1Rx8, on the flip side Dual Rank Memory has a 2Rx on it, for example 2Rx4 or 2Rx8.
