Why do the single- and dual-rank memory modules vary speicher single rank dual rank price? Views Read Edit View history. I've speicher single rank dual rank been told to go with dual-rank over single rank. Wikipedia has a fairly good explanation of rank link. The performance gain that can be achieved is highly dependent on the application and the memory controller's ability to take advantage of open pages.
All that matters for most server admins is that RAM have matching ranks. So to sum up everything, it appears that ranks have more to do with density and pricing than actual performance.

Nevertheless, this pipeline stall is negligible compared to the aforementioned effects. This helped me too. Solutions Learn More Through Courses. Whenever possible, it is recommended to use dual-rank DIMMs in the system. The number of physical DRAMs depends on their individual widths. T - Choose to drain external battery first [Feature Request]. You are diving too deep for configuring the memory for a file server.
When there is no difference in price, choose dual rank over single rank: All that matters for most server admins is that RAM have matching ranks. A rank must be 64 bits of data wide; on memory modules which support Error Correction Code ECCthe bit wide data area requires an 8-bit wide ECC area for a total width of 72 bits.
Join us in building a kind, collaborative learning community via our updated Code of Conduct.

Try it for free Edge Out The Competition for your dream job with proven skills and certifications. I'd say RamCity a vendor for Kingston memory has a more succint explanation on ranks link: It's best albeit more expensive to get the more dense RAM for servers to make room for speicher single rank dual rank upgrades.
Where feasible, the server should have an order of magnitude greater bandwidth than the clients. In practice all DRAM chips share all of the other command and singleton weather forecast bom signals, and only the chip select pins for each rank are separate the data pins are shared across ranks.
Message 4 of 4. Forums Knowledge Base Blogs. The faster memory will be clocked at the specification speed, not the faster speed, and timings e. Experts Exchange Solution brought to you by Enjoy your complimentary solution view. Meaning, the server should run at 1, 2, or 4 Gbps teamed, aggregate bandwidth and the clients typically at Mbps.
On dual rank versus single rank performance: The reason is because of the addressing scheme, which can speicher single rank dual rank the pages across ranks thereby making the pages effectively larger and therefore more page-hit cycles. There are some cases where single rank is preferred: Message 1 of 4. Experts Exchange Solution brought to you by Your issues matter to us.
Ranks are accessed through chip selects CS. Your summing up is pretty accurate, it's density and price, not raw speed that matters for almost all benchmark speicher single rank dual rank and real life, you only need fast memory speed when doing memory intensive graphics or running HPC calculations such as weather forecasts, with general business applications it's quantity rather than quality that gives the speed as if it isn't in RAM it has to be fetched from slow disk.
