5Memory subsystemFor 15G 3rd generation Intel Xeon processor scalable family offers, the best approach to memory configuration is to remember,"Balanced, Balanced & Balanced." Customers should be purchasing balanced configurations to ensure that they can gain theperformance improvements that are being claimed for the platforms. Below is an overview of the DIMM characteristics includingIntel Optane Persistent Memory 200 Series:Topics: DIMM typesDIMM speed and frequencyMemory RAS featuresDIMM typesThe MX750c supports two different dual in-line memory module (DIMM) types that can meet customer needs depending onhow they prioritize R.A.S. (reliability, availability, and serviceability) and power consumption.Dell supports two DIMM types on the MX750c: RDIMM: Registered DIMM – Provides for higher capacity options and advanced RAS features. LRDIMM: Load Reduced DIMM – Provides maximum capacity but higher power consumption.RDIMM , or registered memory, is the most commonly used DIMM type, and offers the best mix of frequency, capacity, and rankstructure choices. It provides high signal integrity - performing parity checking to detect improper addresses or commands - andincreased performance for heavy workloads.RDIMMs (Single Rank and Dual Rank) MaximumMaximumMaximumMaximumfrequency of 3200 MT/s (Depending on processor)frequency using 2 DIMMs per channel of 3200 MT/scapacity of 64GB per DIMMsystem capacity of 2 TBLRDIMM, or load-reduced memory, uses a buffer to reduce memory loading to a single load on all DDR signals, allowing forgreater density.LRDIMMs MaximumMaximumMaximumMaximumfrequency of 3200 MT/sfrequency using 2 DIMMs per channel of 2666 MT/scapacity of 256GB per DIMMsystem capacity of 8 TBDIMM speed and frequencyThe memory offerings for the MX750c is based on double-data rate type 4 (DDR4) memory which operates at 1.2 volts.The processor SKU stack has memory speed support and limits by bin.Table 4.

RAS aids in rapid, accurate diagnosis of faults whichrequire service.The following RAS features are supported on the platform:Table 5. Memory RAS featuresFeatureDescriptionAdvanced ECCAdvanced ECC is a RAS feature that provides error correctionon single-bit and multi-bit failures that are bound within 4bits (nibble) of memory accesses. When used in conjunctionwith DIMMs based on x4 DRAM devices, Advanced ECC mayprovide error correction to an entire single DRAM device.This type of error correction that covers an entire DRAMdevice has been branded in various forms, most popularizedas Chipkill and Single Device Data Correction (SDDC).Memory Page Retire (MPR)Memory Page Retire (MPR) is a feature implemented byPowerEdge server BIOS that instructs operating systems tostop using memory page locations (4 KB in size) that BIOShas deemed as potentially unhealthy - essentially removingit from the operating system's memory pool. This feature isalso known as Operating System Memory Page Retirement orPage Off-lining. BIOS makes the determination of a potentiallyunhealthy memory page based on a proprietary PowerEdgeserver algorithm that takes into account correctable errorpatterns and error rates at a given memory page location.Fault Resilient MemoryIt is a memory RAS feature that leverages partial memorymirroring to create a fault resilient memory region specificallyfor critical memory functions. This will prevent anyuncorrectable errors in this memory region from generating akernel panic or termination of virtual machines or applications.A comparative advantage of FRM versus full memorymirroring is that the memory capacity overhead can beconfigured based on need. The maximum memory redundancyoverhead for FRM is 25% compared to 50% with full memorymirroring.Memory Self-Healing or PPRIt is an industry-standard capability, defined by JEDEC, wherea memory module is capable of swapping out degraded rowsof memory with spare ones being held in reserve. WhileJEDEC requires that all DDR4 memory be built with at leastone spare row per DRAM bank group, Dell requires all memorysuppliers manufacture genuine Dell DIMMs with a significantlylarger number of available spare rows. This is done to ensurethat PowerEdge servers have a robust self-healing memoryecosystem.14Memory subsystem
