“I’ve found some old DIMMs in the house, wonder if they are worth a fortune”

… is the modern equivalent of “I found a potentially valuable antique in the attic”

I would love to go for a walk down memory lane, but the AI bubble and Micron/Crucial are making that far too expensive or no longer an option 😢

My new retirement plan is the drawer full of old DIMMs and SO-DIMMs in my office that I will never, ever have a use for.

Just a thought but your local e-waste recycling centre probably has a lot of older or recyclable RAM and DIMM modules available... 🤔🙂

Anyone who thinks the #SteamMachine aka. #GabeCube / #GabenCube will be a $499 thing or even a $749 thing needs to get updated on #pricing for #hardware.

• Thanks to the "#AI" #Scamconomy, #PriceFixing and #OpenAI buying 40% of global #DRAM production output due to #Trump's "#Stargate" shitshow and the circular #Scam #economy associated, the 2x16GB #DDR5-SODIMMs (even if those were slow -4800 and not the recommended #Zen4 -6000 speeds) will cost about $250+ as of today.

• #SSD|s too - which use the same chip dabs - also climb beyond $100 per TB or > $50 for a 512 GB #NVMe.

So already these components are $300+ as of today, and industry insiders claim this will get much worse so I'm not even shure a $999 pricetag will be possible by Q1/2026. Not to mention the 8GB VRAM of the built-on, dedicaded #GPU!

• Espechally since #Valve, unlike #Sony, #Microsoft, #Apple and #Nintendo will not have the capital to order like #RAM Chips or even sticks in decent qualtities right now.

The only reason why noone expects Apple to raise prices is because they already shaft their buyers by overcharging them for their #SolderedDownRAM & #SolderedDownSSDs and they tend to buy not just huge quantites, paying abovemarket, but also fewer, higher capacity chips.

Tiens, la recherche de l'EPFZ "Phoenix" (CVE-2025-6202) montre que des DIMM DDR5 (produites entre le 2021-1 et 2024-12) de SK Hynix, un de plus grand fabricant mondial de DRAM restent vulnérables au Rowhammer malgré des contre-mesures avancées intégrées dans la puce.

Les chercheurs ont trouvé deux nouveaux schémas d’attaque et une méthode de synchronisation qui contournent les protections intégrées au DRAM.
Les bit-flips obtenus sont exploitables : lecture/écriture arbitraire via PTE, vol de clés RSA/SSH, et escalation vers root (moyenne ≈ 5 min 😵 ). L’ECC embarquée ne suffit pas.
Les auteurs recommandent et démontrent qu’un refresh ×3 empêche Phoenix de provoquer des bit-flips sur leurs tests, au prix d’une surcharge de perf mesurée (+~8%).
