CSV / Excel · 入门版或专业版DDR5 16Gb 4800/5600 averaged $57.667 (+0.29% session) and eTT reached $25.500 (+0.79%). DDR4 出现分化：8Gb 3200 平均价格为 46.107 美元（+0.47%），而 16Gb 3200 则下跌 0.70%，至 83.784 美元。这些是已发布的主板上的会话变化，而不是 30 天的回报。
DRAMeXchange / TrendForce 现货板 ↗DDR5 16Gb 4800/5600 平均价格为 55.233 美元（+0.73%），DDR5 eTT 平均价格为 24.50 美元（+0.82%）。 DDR4 split: 8Gb 3200 rose 0.78% to $46.143 while 16Gb 3200 fell 1.85% to $86.00.该主板的价格仍然处于历史最高水平，但第一个可见的修正出现在选定的旧部件中。
DRAMeXchange / TrendForce 现货板 ↗The 512Gb TLC wafer spot reference fell another 0.31% to $20.083 on 14 September after a 2.71% weekly decline to $20.146. Consumer purchasing remains cautious even while enterprise SSD demand keeps contract pricing elevated.
TrendForce ↗August closed at record fixed transaction prices for both DRAM and NAND, but the monthly pace slowed and Q3 guidance keeps getting trimmed — the level is still making highs while the rate of change rolls over.
MemoryIndex.io ↗Legacy DDR4 is still the fastest line on the board, HBM finally has a public export print at $76 a unit — and for the first time this cycle the forward guidance moved down, not up.
MemoryIndex.io ↗The 1 September session closed with DDR5 16Gb 4800/5600 at a $54.083 average (+0.31%), DDR4 16Gb 3200 at $92.024 (+0.27%) and DDR4 8Gb 3200 at $44.544 (+0.40%). Every line is still green, but the daily session moves are now fractions of a percent rather than the multi-point jumps of June and July. The spread is the story: DDR4 16Gb printed a $117.00 high against a $42.20 low in the same session.
DRAMeXchange / TrendForce 现货板 ↗Sigmaintell's Q3 2026 storage price indicator has supply and demand still tight and every DRAM and NAND category still rising quarter-over-quarter — but the rate of increase has slowed materially versus Q2, with some chips narrowing to single-digit sequential gains. Deceleration is not a reversal, but it is the first thing that has to happen before one.
群智咨询（Sigmaintell）通过 ChainCatcher ↗DRAMeXchange's August fixed transaction price for generic PC DRAM (DDR4 8Gb 1Gx8) settled at $25.00, an all-time high, with NAND also at a record. Both rose more slowly than in July. DRAMeXchange still guides PC DRAM contract prices up 18–23% for Q3 — a large number that is nonetheless smaller than the quarter before it.
亚洲商报 ↗The average export price of a single HBM unit reached $76.13 at the end of August, the first time the figure has cleared $70. Volume HBM4 shipments into hyperscaler AI datacenters, plus a wave of long-term agreements signed by Samsung and SK hynix with big-tech buyers, pulled both HBM and commodity DRAM export values higher.
首尔经济日报 ↗Reported HBM3E spot transactions are clearing at four to five times contracted LTA levels, and Samsung is said to have committed roughly 70% of its memory capacity under long-term agreements running to 2031. If that holds, the free-float supply available to price discovery shrinks further and the spot-to-contract gap stays extreme for years, not quarters.
TrendForce ↗The equal-weighted retail DDR5 composite sits at a $691 average with a $553 minimum, up 2.6% over seven days and 6.3% over thirty. The monthly rate is roughly a third of what the same index was posting in the spring — retail is still climbing, just no longer vertically.
RAM 价格历史记录 ↗KITA data released 31 August shows exports of AI-facing DRAM — HBM and LPDDR — fell from about 681.79 million units in May to 591.74 million in July, a 13.2% drop, while export value rose 18.5% from $11.43B to $13.55B. Fewer bits, far more revenue: the cleanest available proof that this cycle is priced on allocation, not volume.
首尔经济日报/韩国国际贸易协会 ↗The August contract price for commodity PC DRAM (DDR4 8Gb 1Gx8) rose 4.17% month-over-month to $25.00 — a record — even with laptop and PC end demand still weak. HBM 正在吸收用于生产商品位的晶圆产能，因此短缺是供应分配的问题，而不是需求的问题。
首尔经济日报 ↗三星在 NVIDIA 实现 HBM3E 批量出货扩大了合格供应商基础，美光进入 HBM4 12-Hi 资格为 2027 年采购竞赛增添了第三家供应商。更多合格的供应商是 HBM 定价权减弱的唯一最干净的机制。
硅分析师周刊 ↗High prime-wafer prices are squeezing module-maker margins, pushing manufacturers to buy downgraded material for the secondary market. Aside from a few tight specs, the August NAND wafer market is consolidating at a high level rather than extending the run.
TrendForce ↗On 30 August, 7 of 12 tracked 32GB (2x16GB) DDR5 kits at named US retailers were in stock and qualified for the index, at a $15.94/GB median and a $14.38/GB cheapest offer — roughly $460 for the cheapest mainstream 32GB kit.可用性的改善与价格一样值得关注：指数开盘是因为有更多的 SKU 可供购买，而不是因为它们变得便宜。
TechFuelHQ RAM 价格指数 ↗3DCenter's August retail survey put its DDR5 price index at 486% of the July 2025 baseline, up from 445% in July — another 9.20% month-over-month. Retail is now compounding on top of a base that already quintupled.
GameRant / 3D中心 ↗消费者套件的定价是根据数据中心的出价而不是根据个人电脑的需求来定价。 At $1,118 for 64GB, DIY memory has crossed from expensive to prohibitive, which is how retail demand destruction usually begins.
创业财富 ↗合约 DRAM 上季度上涨 13-18%；目前的预测是 8-13%。 Nothing improved on the supply side — the deceleration is entirely demand-side, with PC and smartphone OEMs refusing quotes and cutting configurations.这使其成为一种脆弱的缓解：一旦负担能力重置，同样的供应短缺仍然存在。
硬件克星 ↗With the spot market described as in crisis, BofA modelled a further 20.00% leg up in September across DRAM and NAND. Sell-side price targets have repeatedly lagged the realized tape this year, which cuts both ways when the turn comes.
大高财经 ↗Mainstream 32GB DDR5 kits are clearing near $400 as suppliers prioritize server and HBM allocation. OEM 厂商已经表示，成本将直接转入笔记本电脑和台式机的定价中。
IB时代香港 ↗韩国 DRAM 出口价格上涨了 401.00%，一公斤内存现在价值约 620 克黄金，或 41.7 公斤白银。作为周期极端标记很有用：像这样的商品与金属比率历来都接近顶部。
华创科技 ↗瑞银 (UBS) 预测，SK 海力士 (SK hynix) 将有近 70% 的 HBM4 供应进入 NVIDIA 的 Rubin 平台，而三星 (Samsung) 已从良率挫折中恢复过来，美光 (Micron) 在资格认证方面拥有显着的上升空间。每个加速器的 HBM 订单项价格已达到 2,400-6,500 美元，因此供应商组合会直接移动加速器 BOM。
Silicon Analysts ↗随着晶圆分配转向 HBM 和 DDR5，商品 DRAM 产量下降，设备 BOM 膨胀——目前预计手机和 PC 价格将上涨 15-40%。更高的设备价格最终会减少单位销量，这是这个循环的自我纠正终点。
今日数码 ↗TrendForce work published August 25 has memory overtaking GPUs as the largest line item in cloud infrastructure spend by 2027, and NVIDIA is already leaning on that math to justify roughly 15% higher server pricing.
科技时报 ↗Memory is forecast to absorb 68% of the big cloud providers' component capex in 2027. That concentration is what keeps suppliers' pricing leverage intact even as hyperscalers push back on cost.
TrendForce ↗Chosun Biz 数据显示，韩国 DRAM 出口价格比周期低点高出 12.5 倍，目前每公斤价格是白银的 41.7 倍。这次反弹的幅度和持续时间都超过了之前的每一次内存上涨周期。
TrendForce ↗两家韩国供应商都在推动 HBM4 的发展，以满足 NVIDIA 和数据中心的需求。更快的 HBM4 产量有利于收入，但有利于目前 HBM3E 定价中的稀缺性溢价。
诺亚智能 ↗Micron told Hot Chips that HBM consumes roughly three times the wafer area per gigabyte of DDR5, and the penalty grows with each generation. Every incremental HBM bit therefore removes more conventional DRAM supply than the last — the mechanical core of this shortage.
汤姆的硬件 ↗在硅谷的 Hot Chips 上，SK 海力士确认第六代 HBM4 12 层部件已进入量产，16 层堆栈已通过资格认证。资格认证时间（而非晶圆开工）仍然是 2027 年 HBM 供应的约束因素。
先驱商业报 ↗SK 海力士将通过 NVIDIA Rubin 扩展 MR-MUF 封装，而不是在 HBM4E 上采用混合键合，从而推迟到 HBM5 的切换。封装选择决定了堆叠产量，而堆叠产量决定了 HBM 实际发货量。
汤姆的硬件 ↗The same 32GB DDR5 kit has gone from roughly $72 to $392 in about fourteen months — a 444.44% increase with no change in the part. Retail is where the AI buildout's cost is landing on ordinary buyers.
帕斯卡莱·皮利特里 ↗三星提前达到约 80% 的 HBM4 良率，扩大了 NVIDIA 下一代加速器的供应，并对 SK 海力士的分配优势构成压力。第二大供应商的产量恢复是 HBM 定价走软的最快途径。
创业财富 ↗Some DDR5 kits are up nearly 500.00% year-over-year, breaking a twenty-year pattern of falling cost per bit. The structural read: memory has repriced from a deflating commodity to a rationed input.
HTX 见解 ↗Samsung's ~50% HBM capacity expansion matters little until 12-layer stacking yields land, while SK hynix's 1c-node maturity gives it a structural allocation edge capex cannot close. For buyers, the constraint is qualified shippable HBM, not gigabytes of theoretical capacity.
Silicon Analysts ↗超大规模买家已保留了几乎所有 2027 年 DRAM 产量，预付款已用完至 2030 年，剩下的部分由商业渠道竞标。预订能力是现货结算持续高于合约的原因。
门新闻 ↗人工智能需求推动服务器 NAND 合同向前推进，而消费者库存消化缓慢则导致谈判陷入停滞，导致现货盘整。从长远来看，供应商将结束资本支出削减并恢复扩张——这是 2028 年供应响应的准备。
TrendForce ↗PCPartPicker 显示 2x16GB DDR5-4800 同比增长 372.00%，2x32GB DDR5-5600 同比增长 485.00%。速度箱之间的差距已经缩小——买家为容量而不是频率付费。
技术加电 ↗传统 DDR4 仍然是主板上最暴力的产品线，HBM4 的第一个可靠打印价格约为 500 美元/堆栈，该周期的第一个真正的熊市信号出现在晶圆厂资本支出中，而不是价格中。
MemoryIndex.io ↗大容量套件现在的价格高达其最低追踪价格的十倍，其中 128GB DDR5 售价为 3,399 美元。工作站和家庭实验室买家是第一批被完全定价的群体。
汤姆的硬件 ↗强劲的企业级SSD和QLC需求正在加速高层工艺迁移和扩容，而服务器和消费者需求却出现巨大分化。消费端是原本紧张的 NAND 市场的软肋。
TrendForce ↗三星、SK 海力士和美光正在从季度合同转向多年供应协议，这可能会缓和（但不会结束）繁荣与萧条周期。合同越长意味着两个方向的价格发现速度都会变慢。
韩国先驱报 ↗在内存发生四倍变动后，苹果、汽车制造商和医疗设备制造商正在迫切要求制定分配规则和 CHIPS 法案的救济措施。政策干预是现货市场未定价的价格曲线的活尾风险。
AI2Work ↗买家并没有对创纪录的价格犹豫不决，而是竞相确保供应——这就是需求曲线缺乏弹性的定义。定价权一直持续到产能下降或终端市场崩溃为止。
阿尔法飞行员 ↗在 KeyBanc 技术领导力论坛上，美光表示客户收到的 DRAM 还不到他们要求的一半，2027 年的供应应该比 2026 年更紧张。现在的谈判变量是分配，而不是价格。
市场节奏 ↗三星将根据多年协议锁定 60-70% 的产能，而 SK 海力士则保留更多现货产能。此次拆分是对价格是否会持续上涨到 2027 年的直接押注。
今日数码 ↗Roughly $38 billion of customer prepayments, deposits and collateral has moved supplier leverage to an all-time high. The same reporting flags 2029 as the point where new capacity could hand the balance of power back to buyers.
华创科技 ↗在 SK hynix 批准一项 38B 美元的晶圆厂计划后，内存和存储品牌遭到抛售，投资者将这笔支出视为恢复供应过剩的第一条可靠途径。新的前端产能需要 7-9 个季度才能生产比特，因此风险出现在 2027-28 年，而不是本季度。
24/7 华尔街 ↗据报道，长鑫存储正计划在北京建设第二座 DRAM 工厂，目标是到 2026 年底产量接近美光科技的产量。中国商品 DDR4/DDR5 供应是传统 DRAM 价格曲线面临的最大下行风险。
寻找阿尔法 ↗三星以 39.00% 的份额重新夺回 DRAM 收入桂冠，回到 2024 年的水平。 SK 海力士收入同比增长 214.00%，但从 39% 下降至 26%。美光科技落后一分，为 25.00%，是 2014 年以来最接近的水平。长鑫存储和南亚科技是增长最快的。
对位研究 ↗A dated listing check found $214.99 for a single 16GB module, $399.99 at 32GB and $869.99 at 64GB. The WhereIsMyRam tracker put US retail up 13.70% over the prior 30 days; premium EXPO kits now list as high as $1,099.
TechFuelHQ / Newegg 检查 ↗SK 海力士公布了 HBM 和传统 DRAM 实力创纪录的季度业绩，但结果并未得到一致认可，股价下跌。错过高峰周期收益是即使市场短缺的预期也超前的典型标志。
调整镇 ↗Consumer SSD pricing has roughly tripled through the component crisis. Trackers now show 2TB NVMe flat over 30 days and down 42.00% over 60 from the spike - the first sign of retail cooling.
汤姆的硬件 ↗内存现在在 PC 物料清单中所占的份额足够大，以至于 OEM 正在提高价格并推迟刷新周期，并且单位出货量下降。客户需求破坏是最终限制 DRAM 价格曲线的机制。
调整镇 ↗HBM3E is the dominant stack in production AI systems, with SK hynix HBM bit share read at 50-55%. Both SK hynix and Micron have HBM4 in qualification for MI400-class parts, so the next transition is already underway.
Silicon Analysts ↗尽管 DRAM 定价创下纪录，但美光股价仍出现回调，投资者质疑超级周期利润率已经打折了多少个季度。价格翻转之前的股市疲软是一个反复出现的记忆周期信号。
通过 AOL 寻求 Alpha ↗尽管人工智能和企业需求使批发水平保持在较高水平，但由于买家拒绝当前的 RAM 和 SSD 定价，零售销售正在放缓。消费者渠道是链条中第一个被打破的环节。
雅虎财经 ↗创纪录价格的模块厂商和 DIY 买家完全退出市场，DRAM 季度涨幅最大。对供应商来说价格有利，但这是数据集中最明显的需求破坏信号。
TweakTown / SigmaIntel ↗收入从上一季度的 $23.86B 上升至 $41.46B，GAAP 净利润为 $28.24B，运营现金流为 $25.4B。管理层提出了转型战略客户协议——预付款结构现已成为整个行业的标准。
美光（SEC 备案） ↗传统 DRAM 合约价格环比上涨约 93-98%。随着人工智能从训练转向推理，CSP 也在购买通用服务器，将需求从 HBM3E 和 LPDDR5X 扩大到广泛的 RDIMM 容量。
TrendForce ↗人工智能和通用服务器需求拉开了企业级SSD严重的供需缺口。供应商正在将产品组合转向低延迟、高利润的驱动器，旨在降低人工智能推理成本。
TrendForce ↗
