ASUS is working on a DDR4-DDR5 adapter

This will also come in handy due to the downturn in DDR5 prices, as many manufacturers have used the DDR5 socket for the motherboard.

The introduction of the DDR5 memory standard will apparently be extremely difficult, as not only will the premium for the standard novelty be paid for, but also the lack of components, so DDR5 memories are currently extremely expensive. So much so that the price of memory alone can be more than the value of the other components in the designed PC combined, which is quite inconvenient for manufacturers. Just because the vast majority of motherboards designed for Alder Lake-S processors are designed to accept DDR5 DIMMs, DDR4 is mostly only supported by motherboards with specifically minimalist capabilities.


The question is what can be taken out of the situation, as Micron says the shortage of components for DDR5 memory will not ease until the second half of this year.

A Bing A video has recently been posted on a Chinese Youtube channel called the solution to the above situation. It features an ASUS-designed ROG adapter that plugs into the DDR5 DIMM socket on the motherboard and turns it into a DDR4 DIMM socket that can now hold wallet-friendly DDR4 memory.

Implementing the above is quite complex because there are quite a few differences between the two memory standards. On the one hand, DDR5 is already multi-channel projected on a single module, which needs to be handled, but the biggest difficulty is the difference in power management. For DDR4 this is the job of the motherboard, while for DDR5 it is the memory module. Because DDR5 motherboards logically expect DDR5 memories to be used by the user, the components required for power management are also omitted from the motherboard, but these are brought back by the adapter in question.

The video above also shows the system in action, for the time being in single-module mode, as two-channel operation in this form is extremely difficult to achieve – it takes a lot of luck and a perfect combination of stars. The DDR4 memory inserted in the adapter also works with the JEDEC profile, which is required to maintain stability.

Of course, such an adapter is not an optimal accessory, but it would be very expensive for motherboard manufacturers to redesign DDR5 motherboards that have already been released and are still being made to DDR4, so they will try to bridge the DDR5 memory shortage with an adapter. up to the JEDEC profile stored in that DDR4 memory is guaranteed to work. Of course, if you buy an Alder Lake-S processor, you want more than that, but nowadays the chances are that you won’t be able to get DDR5 memory at a high price, at least with an adapter like this, until the component deficiency is alleviated.
