Weekly Memory Brief: AI CapEx, CXMT Earnings & GPU Power Safety — August 31

Published 31 August 2026, Australia/Sydney. Coverage: 24–30 August 2026.

This week’s practical read: DDR4 spot quotes firmed without a matching surge in transactions, CXMT filed a striking but unaudited half-year report after Friday’s close, and viral GPU-power modifications turned connector installation back into a PC-building safety issue.

1. Storage market: firmer DRAM, cautious NAND buyers

AI-server demand supports memory pricing, but spot buyers remain selective.

Fact: DRAMeXchange’s daily notes put the average spot price of DDR4 8Gb (1Gx8) 3200 at US$43.288 per chip on 24 August and US$44.189 on 28 August, a rise of about 2.1%. The same 28 August note still described weak purchasing willingness and unsatisfactory transactions. In NAND, suppliers mostly held quotes while buyers focused on specific parts; trading remained sluggish. These are component-level spot indicators, not prices for Australian RAM kits or SSDs.

Forecast and uncertainty: The week’s new TrendForce outlook projects cumulative 2026 contract-price increases of roughly 270% for server DRAM and 235% for enterprise SSDs. Those are full-year projections for large buyers—not weekly moves or retail forecasts. Price caps in some new long-term agreements may temper further increases, while future fab ramps and soft client demand remain counterweights. Our read: enterprise AI demand is reinforcing tightness, but one should not infer a uniform consumer SSD increase from it.

2. CXMT stock update: trading, then a post-close filing

CXMT is now in public-market price discovery, with a new post-listing filing to assess.

Fact: CXMT is publicly listed and has traded on Shanghai’s STAR Market since 27 July. 688825 is the tradeable stock code, 787825 was the online subscription code, and CNY 8.66 per share was the IPO issue price—not the current quote. On 29 August, CXMT published its unaudited 2026 half-year report: revenue was CNY 150.31 billion and net profit attributable to shareholders was CNY 77.61 billion, versus CNY 15.44 billion revenue and a CNY 2.33 billion loss a year earlier. The company linked the change principally to DRAM undersupply and higher product margins.

Market data: Investing.com’s delayed Shanghai history shows a CNY 58.60 close on 28 August, versus CNY 58.00 on 21 August—about +1.0% week on week. The filing arrived after Friday’s market close, so that price does not represent post-report trading. A short public history, an unusually large gap from the issue price and cyclical memory pricing all limit simple comparisons. This is general information only, not investment advice.

3. PC DIY topic: GPU power safety beats viral soldering

A fully seated, correctly matched and strain-free cable is the practical priority.

Heat signal: Posts about directly soldering power wires to an extreme RTX 5090D board drew hundreds of Reddit votes across r/overclocking and r/hardware on 29–30 August; a separate user failure report also attracted attention. Engagement and anecdotes do not establish a failure rate or root cause. Tom’s Hardware reported that the chiller-cooled demonstration ran near 600W and explicitly warned readers not to copy it.

Verified takeaway: NVIDIA’s RTX 5090 guide specifies at least a 1,000W system PSU and either its included four-to-one adapter or a 600W-or-greater PCIe Gen5 16-pin cable. The revised 12V-2x6 design uses shorter sense pins and longer power contacts to improve seating detection, but installation still matters. Use only a cable approved for the exact PSU, never mix modular PSU cables, seat both ends fully, avoid a severe bend or side-load near the plug, and stop immediately if you see discoloration or smell overheating. Direct PCB soldering is not a consumer fix.
