#ddr4 — Public Fediverse posts

Live and recent posts from across the Fediverse tagged #ddr4, aggregated by home.social.

  1. Memory earnings season opened with numbers that would have been typos three years ago: $61 billion in quarterly operating profit at Samsung, $41.5 billion in revenue at Micron against $9.3 billion a year earlier. Q3 contract talks point to DRAM rising another 13–30%, NAND 10–40%.

    The more interesting shift is the forecast horizon. On the day of its $26.5 billion Nasdaq debut — the largest ever US listing by a foreign company — SK hynix called 2027 the worst supply year in the industry's history and said demand will outrun capacity beyond 2030. Customers reportedly asked for five to six times as much supply; some offered to buy the fab equipment outright. Meanwhile, wafer allocation keeps tilting toward HBM, leaving standard DDR4/DDR5 undersupplied and pushing buyers into the secondary market.

    The full Q3 market update, including the case for skepticism about that 2030 forecast:

  2. SK hynix's parent group says it may offer "Memory as a Service" — RAM capacity sold like a cloud subscription rather than a chip in a box. The idea is early, but the hardware underneath it is not.

    This explainer walks through the full stack: why memory gets stranded inside servers, how CXL adds the cache coherency that PCIe never had, what memory appliances and CXL 3.0 switches actually do, and why tiering keeps local DRAM first. It also draws a line many articles blur — memory expansion (which Meta already runs across millions of servers, reusing retired DDR4) versus rack-level pooling, which is only now reaching real silicon.

    The business angle matters too: subscriptions would smooth the boom-and-bust cycle memory makers have never escaped. And for everyone else, the takeaway is simpler — memory is becoming an asset with value independent of the server it shipped in.

Ich bin da zum Glück raus, da ich mein System 2025 noch relativ günstig auf den kleinen Bruder 5700X3D aufgerüstet hatte. Aber ja, der 5800X3D ist schon gut, aber so ca. 229€ hätten für mich preislich eher Sinn ergeben.

  13. An analyst note in early June called a mid-2026 peak for DRAM and NAND prices, and it made headlines. The actual market data is more interesting. Conventional DRAM contract prices rose 93–98% in Q1 and are still rising in Q2 — but spot buyers have started balking at higher quotes, and NAND spot trading has gone quiet. The first sign of strain isn't falling prices. It's fading demand.

  19. MemForge2: загрузочная флешка, которая за минуту говорит — какую планку памяти менять

    Сегодня собирал HP EliteDesk 8300, четыре планки DDR3 по 2 ГБ. При первой загрузке — синий экран Windows. Стандартный сценарий: сейчас полчаса вытаскивать планки по одной, перезагружаться, выяснять какая сбойная. «Танцы с бубнами», которые каждый сервисник делал тысячу раз. Потом вспомнил, что у меня есть собственный инструмент ровно для этого. Воткнул флешку, прогон, минута — на экране большими буквами: REPLACE DIMM1, confidence HIGH . Чтобы убедиться что программа не «запоминает» слот а реально находит планку, переставил её в DIMM4. Прогон повторно — нашла её и в DIMM4, тот же серийник из SPD. Замена планки — BSOD больше нет. Я работаю на сборке ПК — и новых, и б/у. На б/у это типичная ситуация: всё собрано, провода уложены, включаешь — синий экран на загрузке. Метод исключения работает, но это перезагрузка за перезагрузкой, глубокий вдох перед каждой, час твоего времени уходит на то, что должна была бы решить минута. Мне нужен был инструмент, который сразу показывает где проблема — без часовых прогонов и без танцев со свапами планок. Готового с такой комбинацией возможностей я не нашёл, поэтому собрал свой. Сразу честно про авторство. Я не программист. Я сборщик. Код MemForge2 писал не я — его писал Claude (LLM от Anthropic) под мою постановку задачи. Я приходил с пониманием предметной области («нужно SPD через SMBus, серийник для гарантии, MCA‑снимок до/после, контекст в момент ошибки»), описывал что должна делать программа на конкретных кейсах со своей сборки, гонял каждую версию на реальном железе, ловил баги, возвращался с дампами и описаниями поведения. Claude писал C, разбирался с UEFI‑API, MSR‑ами, SMBus‑протоколом, SPD JEDEC‑стандартом.

  23. Как работать с DDR4

    Доброго дня. Сегодня я хотел бы рассказать о DDR4 в контексте модулей памяти. 1) Чуть-чуть об авторе Автор имеет опыт в коммерческой разработке печатных плат около двух лет. До начала этого пути занимался баловством с микроконтроллерами на самодельных платах. На текущий же момент можно перечислить два значимых успешных проекта: материнская плата на RK3588 (LPDDR4X-4266MT/s, HDMI2.1, PCIe2/3, Ethernet 2.5G, USB2/3, SATA3), модуль памяти UDIMM DDR4 3200 MT/s. Разумеется, было много прочих, но они не требовали глубокого понимания работы с согласованием сигналов по задержке, понимания импеданса. Стоит учитывать, что автор является самоучкой чуть более чем полностью, так как более опытных коллег попросту не было и нет. Опыт работы имеется только с российскими фабриками. Разработка велась в Altium, какого-либо моделирования (Cadence/Ansys/иной софт) не проводилось. Однако, проекты полностью работоспособны, что является косвенным доказательством валидности моих эвристик. Последний вводный абзац. Если будет интерес и потребность – планируется сделать еще одну статью о workflowпри работе с DDR4 в Altium. Также есть что рассказать про LPDDR4, если будет таковой запрос. Если есть интерес к разработке печатных плат – по ссылке доступно мое «пособие», полностью свободное.

  24. Помните 30-контактные SIMM? Полная история RAM: от первых планок до 512 ГБ DDR5

    В 1981 году IBM PC 5150 поставлялся с 16 или 64 КБ оперативной памяти, а максимальная конфигурация ограничивалась 640 КБ — архитектурным барьером первого поколения процессоров Intel. Сегодня флагманские десктопы и серверы оснащаются 192 ГБ DDR5-памяти. Это рост в 300 000 раз за четыре десятилетия. И памяти все также не хватает. За это время сменилось больше десятка стандартов: 30-контактные SIMM, которые нужно было устанавливать парами, продуваемые EDO-модули, провалившаяся RIMM для Pentium 4 и пять поколений DDR. В этой статье постараемся разобраться, как менялась оперативная память для десктопов и серверов.

  25. Just looked up for how much the RAM sticks in my main system would sell for today. And well. They'd sell for more than the entire system (dual EPYC cpus, server motherboard, and all of the RAM included) cost. It basically 5x-ed in price. The exact sticks I have.

    So people DO NOT look it up.

  27. Samsung has finalized a ~30% DRAM price hike for Q2 2026 contracts, following a staggering doubling of prices in Q1. Yet, across retail outlets and secondary channels, we are seeing a surprising—and confusing—price drop. What is actually behind this massive market decoupling?

    The "Paradox of 2026" isn't a sign that the AI boom is over; it's a sign that the market has split into two different realities. While the headlines scream about hikes, the ground-level data shows a localized correction that savvy IT managers can leverage.

    Here is what is really driving the disconnect:

    🔹 The $600B Hyperscaler CapEx Wave: With OpenAI securing a record $122B and total AI infrastructure spending hitting $602B this year, titans like Microsoft and Meta are "vacuuming" up wafer capacity. Suppliers are prioritizing high-margin HBM3E, leaving standard DIMM supply structurally tight for the long term.

    🔹 Asia-Led Spot Market Flushes: The recent price dips originating in Taiwan and Shenzhen aren't a reversal of demand. Instead, they reflect short-term inventory corrections and "fire sales" from traders who over-leveraged during the Q1 surge. This creates a temporary window of lower prices in the spot market that doesn't match the rising cost of new factory contracts.

    🔹 The "Inference Inversion": While DDR5 gets the headlines, DDR4 is becoming a "scarcity play." As manufacturers phase out legacy lines to make room for AI chips, DDR4 prices are remaining "sticky" even when consumer demand softens, because new supply is simply vanishing.

    Understanding the widening gap between enterprise contract rates and retail spot prices is now critical for timing your next infrastructure upgrade or hardware liquidation.

    The "Paradox of 2026" comes down to a few key factors:
    - The $600B Hyperscaler CapEx wave siphoning critical wafer capacity.
    - Why Asia-led spot market drops reflect inventory flushes rather than a demand reversal.
    - The "Inference Inversion" keeping DDR4 prices sticky despite consumer-side volatility.

  34. The DRAM market in 2026 is no longer moving as a single cycle.

    DDR5 prices are finally declining at the retail level, driven by weakened consumer demand, inventory liquidation, and improved AI memory efficiency. At the same time, enterprise demand continues to surge as massive AI infrastructure investments absorb global supply.

  36. Как Китай снижает цены на DDR4 и пытается занять освободившийся рынок памяти

    Рынок ОЗУ в последние полтора года больше похож на американские горки, чем на привычный бизнес с предсказуемыми циклами. Цены на модули DDR4 взлетели так резко , что сборщики систем порой пересчитывают сметы по три раза за месяц. Многие пользователи откладывают апгрейд, надеясь, что ситуация выровняется сама (вряд ли). На этом фоне китайская Changxin Memory Technologies вывела на рынок чипы по цене вдвое ниже привычных. Похоже на продуманную стратегию. Давайте разбираться, тут много интересного.
