Feeling the pinch of high-tech prices? A resourceful Russian modder, VIK-on, took matters into his own hands and crafted his own DDR5 memory module, potentially saving a whopping $600 to $800! This DIY project offers a fascinating look at how tech enthusiasts are finding innovative solutions to expensive hardware.
VIK-on's journey began with salvaging laptop SO-DIMM chips to build a 32GB DDR5 desktop memory stick. He sourced the donor chips from two 16GB SO-DIMM modules, each costing around 8,000 rubles. Add to that a new PCB for about 50 yuan (approximately 600 rubles) and a basic heatsink from AliExpress for another 415 rubles, and the total build cost comes to roughly 17,015 rubles, which is about $218 for a single 32GB stick.
Compared to the current market prices in Russia, this is a significant saving. Commercially available DDR5 memory can be quite expensive; for instance, DDR5-4800 32GB memory costs around $423, and 6400 CL32 memory goes for about $588. In the US or EU, these prices can easily soar even higher.
But here's where it gets controversial: the magic lies in the firmware. VIK-on flashed the module with ADATA firmware, enabling an XMP profile at DDR5-6400 CL32 right away. This specific profile, from ADATA AX5U6400C3232G-DCLARWH, usually costs around $800. This highlights how crucial firmware can be in unlocking the full potential of hardware.
It's important to note that this isn't entirely 'free' memory. The SO-DIMMs still need to be purchased, and the process involves sourcing a compatible PCB and transferring the chips. However, the demand for laptop SO-DIMMs is generally lower than for desktop UDIMMs, making the parts potentially easier to find.
VIK-on also explored a cheaper variant using 8GB sticks, but different chip packaging complicated the PCB choice. In that scenario, the best outcome would likely be a 16GB stick with parts costing around 5,000 rubles, running at speeds closer to DDR5-5600.
While full benchmarks are still pending, VIK-on reports stable performance in games so far. He plans to release a video showcasing the build once he completes more modules.
