Enthusiast Builds DDR5-7800 Desktop Kit from Laptop Memory for 300 Manat

An electronics enthusiast known as “Blighted Agent” has converted a 32 GB RAM kit designed for laptops into high-speed desktop memory. He bought the kit from “Facebook Marketplace” for $120 (approximately 200 manat). The kit contained 2 “SK hynix” modules, each with 16 GB of capacity. The memory, which initially ran at DDR5-5600 speeds, reached DDR5-7800 after the modification. According to the enthusiast, the finished kit is worth approximately $1,000 (1,700 manat).
Blank desktop DDR5 boards were purchased from “AliExpress” for the project. Each board cost $16 (approximately 27 manat). Another $18 (approximately 31 manat) was paid for the heat spreader covers attached to the memory modules. The total cost was $175 (approximately 300 manat). The chips are believed to be the same “SK hynix” A-die chips used in expensive “G.Skill Trident Royal” modules. First, the memory chips were removed from the laptop modules using a hot-air station and cleaned. Small 0.45 mm solder balls were then placed on the chips. The prepared chips were attached to the blank desktop boards using solder, a special liquid, a heater and hot air. Finally, the SPD and BIOS chips that store the memory configuration data were also transferred from the old modules to the new boards. During the initial test, the modules were correctly recognized by the “Asus ROG Maximus Z790 Apex Encore” motherboard. The system showed each module as having 16 GB of memory and a speed of 5600 MHz. After further tuning, the memory operated in DDR5-7800 CL38 mode. The voltage was 1.40 V, and the system remained stable. Stability was verified with a 90-minute stress test. The enthusiast considers this result sufficient for a gaming PC.
Secondhand DDR5 SODIMM kits, or laptop memory kits, are usually considerably more expensive than the one purchased for the project. In the US market, the lowest price for a working 32 GB kit was $320 (approximately 540 manat). A new 32 GB DDR5-6000 kit sells for even more. Its lowest price is $449 (approximately 760 manat). Therefore, finding a working kit for $120 is considered a good deal. “Blighted Agent” has experience soldering chips onto boards. He has previously increased the VRAM, or video memory capacity, of graphics cards as well. However, special testing equipment is needed to identify a fault in a single chip during the process. Another enthusiast known as “VIK-on” has also completed a similar project. By writing custom software for the modules, he managed to have them automatically recognized by most motherboards with a 6400 MT/s XMP setting.
