Modder Overclocks Laptop DDR5 to 7800 MT/s for $175 Total Cost

A hardware modder has shown that laptop memory chips can be utilized in desktops. This means there is a way to save money as a system builder. So you can save money by using laptop modules to avoid high prices of high-speed desktop memory modules. This is a really cool project that shows there is a way to get high performance without high prices for those looking for high-end systems on a tight budget.

SK Hynix A-die chips modified for desktop use achieve top-tier speeds at a fraction of the cost

This hardware modder has shown the ability to take SK Hynix DDR5-5600 SODIMM memory chips and actually put them on desktop DIMM PCB boards. He has performed a BGA reball for these chips. He also moved the SPD and BIOS chips around. So what he's done is turn laptop memory into desktop memory effectively.

Specifications

• Original Form Factor: SODIMM (Laptop)
• Target Form Factor: DIMM (Desktop)
• Memory Chips: SK Hynix A-die
• Original Frequency: 5600 MT/s
• Overclocked Frequency: 7800 MT/s

The memory chips in this project are SK Hynix A-die. These are the top-tier memory chips in the industry at the moment. These were running on the original laptop modules at 5600 MT/s. Now what's been done in the desktop kit, he was able to overclock it to 7800 MT/s which is the same speed as the top-selling high-speed desktop memory kits out there right now.

It cost him $175 USD to get all of the necessary materials to do this hardware mod. That's a big saving when it comes to high-speed desktop memory kits which are pre-built with the same type of specifications. The original laptop memory cost $120 USD. So the rest was the PCB and labor cost.

The video was put out there by a user called Kuai Keji on YouTube. There is all kinds of technical information about this project. It's been proven that it's possible to do it with the hardware mod.

It's been shown that you can get high performance targets in this hardware mod. Now whether or not these modified memory modules will work on different desktop motherboards in the long term for stability, that's not something that's been tested independently.
