IT Home December 31 news, according to foreign media techpowerup news, a YouTube user @Lin Da Bing released a video on December 30, showing a memory adapter card developed by ASUS, which can operate normally after real testing. This product can transfer DDR4 memory modules to the DDR5 memory slot, which can be convenient for users who want to experience the top-of-the-line Z690 motherboard and are not willing to spend a lot of money on DDR5 memory.
As can be seen from the figure, the height of the ROG riser card is relatively large, and there are many components such as inductors, capacitors, MOS tubes and so on the front. Since the DDR5 memory is powered by +5V DC and the default supply voltage for DDR4 memory is 1.2V, the riser card needs to include a DC-DC supply circuit. Because the signal pin definitions of DDR4 and DDR5 are different, the riser card also needs to be processed in terms of signal.
IT House learned that DDR5 memory splits a single 64-bit channel into two 32-bit channels, with an inconvenient total number of bits, to achieve the effect of a single dual channel.
The Up master also discussed from a theoretical level, trying to install DDR4, DDR5 memory and run on a single computer at the same time. Foreign media said that he is responsible for some product research and development of the ROG Player Nation brand.
According to it Home, Samsung has said that the current shortage of DDR5 memory is mainly due to the shortage of PMIC power chips, while DRAM particles are relatively sufficient. Since this riser card also requires a power chip for bucking, the product cannot be supplied on a large scale. At present, ASUS has not officially announced this transfer card, and it is unknown whether it will be mass-produced and sold.
