Amid a global DDR5 shortage and soaring prices, Russian hardware enthusiasts are experimenting with do-it-yourself DDR5 RAM by sourcing empty PCBs and soldering memory chips by hand. Tom's Hardware reports: The idea comes from Russian YouTuber PRO Hi-Tech's Telegram channel, where a local enthusiast known as "Vik-on" already performs VRAM upgrades for GPUs, so this is a relatively safe operation for him. According to Vik-on, empty RAM PCBs can be sourced from China for as little as $6.40 per DIMM. The memory chips themselves, though, that's a different challenge. The so-called spot market for memory doesn't really exist at the moment, since no manufacturer has the production capacity to make more RAM, and even if they did, they'd sell to better-paying AI clients instead. Still, you can find SK Hynix and Samsung chips across Chinese marketplaces if you search for the correct part number, as shown in the attached screenshots. Moreover, the Telegram thread says it would cost roughly 12,000 Russian Rubles ($152) to build a 16 GB stick with "average" specs, which is about the same as a retail 16 GB kit. There's also a ZenTimings snapshot showing CL28 timings, claiming that even relatively high-end DDR5 RAM can be built using this method, but it won't be cost-effective. Therefore, it doesn't make too much sense just yet to get the BGA rework station out and assemble your own DDR5. Things are expected to get worse, though, so maybe these Russians are on to something.
