In April 2020, the final BIOS-based version, 5.31 beta, was released with a short changelog claiming "many fixes". [14] [15] In May 2020, Martin Whitaker forked Memtest86+ 5.31 into PCMemTest, rewriting it for UEFI support, DDR4 and DDR5 RAM, and supporting all current AMD and Intel chipsets and CPUs. In October 2022, this branch merged back ...
DDR5 octuples the maximum DIMM capacity from 64 GB to 512 GB. [8] [3] DDR5 also has higher frequencies than DDR4, up to 8GT/s which translates into 64 GB/s (8 gigatransfers/second × 64-bits/module / 8 bits/byte = 64 GB/s) of bandwidth per DIMM. Rambus announced a working DDR5 dual in-line memory module (DIMM) in September 2017.
Rowhammer (also written as row hammer or RowHammer) is a computer security exploit that takes advantage of an unintended and undesirable side effect in dynamic random-access memory (DRAM) in which memory cells interact electrically between themselves by leaking their charges, possibly changing the contents of nearby memory rows that were not addressed in the original memory access.
In 2019, ADATA Technology's annual pre-tax net profit was NT$650,875 thousand, and the after-tax net profit was NT$441,769 thousand, with earnings per share of NT$2.04, ranking second among the top ten global SSD module brands.
In computer security, a cold boot attack (or to a lesser extent, a platform reset attack) is a type of side channel attack in which an attacker with physical access to a computer performs a memory dump of a computer's random-access memory (RAM) by performing a hard reset of the target machine.
Single Data Rate Synchronous DRAM (SDR SDRAM) DIMMs were primarily manufactured in 1.5 inches (38 mm) and 1.7 inches (43 mm) heights. When 1U rackmount servers started becoming popular, these form factor registered DIMMs had to plug into angled DIMM sockets to fit in the 1.75 inches (44 mm) high box.
Bank 1 primary SDRAM width (1–127, usually 8) Width of bank 1 data SDRAM devices. Bank 2 may be same width, or 2× width if bit 7 is set. 14: 0x0e: Bank 2 2×: Bank 1 ECC SDRAM width (0–127) Width of bank 1 ECC/parity SDRAM devices. Bank 2 may be same width, or 2× width if bit 7 is set. 15: 0x0f: Clock delay for random column reads ...
