The exponential growth of PC memory sizes, driven by the equally exponential drop in memory prices, was also a factor in this, as the duration of a memory test using a given CPU is directly proportional to the memory size. The original IBM PC could be equipped with as little as 16 KB of RAM and typically had between 64 and 640 KB; depending on ...
The specification defined standards for ×4, ×8 and ×16 memory devices with capacities of 2, 4, 8 and 16 Gbit. [1] [47] In addition to bandwidth and capacity variants, DDR4 modules can optionally implement: ECC, which is an extra data byte lane used for correcting minor errors and detecting major errors for better reliability. Modules with ...
The DDR4 SDRAM is a high-speed dynamic random-access memory internally configured as 16 banks, 4 bank groups with 4 banks for each bank group for ×4/×8 and 8 banks, 2 bank groups with 4 banks for each bank group for ×16 DRAM. The DDR4 SDRAM uses an 8n prefetch architecture to achieve high-speed operation.
PCMark is a computer benchmark tool developed by UL (formerly Futuremark) to test the performance of a PC at the system and component level. In most cases, the tests in PCMark are designed to represent typical home user workloads. [citation needed] Running PCMark produces a score with higher numbers indicating better performance. Several ...
Memory diagnostic software programs (e.g., memtest86) are low-cost or free tools used to check for memory failures on a PC. They are usually in the form of a bootable software distribution on a floppy disk or CD-ROM. The diagnostic tools provide memory test patterns which are able to test all system memory in a computer.

RDRAM memory with integrated heat spreader A Samsung RDRAM PC-600 128 MB A Samsung RDRAM Installed with Pentium 4 1.5 GHz. The first PC motherboards with support for RDRAM debuted in late 1999, after two major delays. RDRAM was controversial during its widespread use by Intel for having high licensing fees, high cost, being a proprietary ...
