Earlier this morning, we reported that ASRock was working on a new memory standard. The brand’s aim is to offer inexpensive DDR5 kits for business PCs and office machines. Although not commercially available, the operation of this memory was simulated by blocking one of the 32-bit channels of a conventional UDIMM kit.
HUDIMM performance at half-mast!
A piece of adhesive to simulate the behavior of this type of RAM!
In a nutshell, to simulate the operation of HUDIMM memory, one of the stick ‘s two 32-bit channels was prevented from being detected using adhesive tape. The whole thing was mounted on an ASUS motherboard, while a BIOS allowing detection of this type of memory was used.
In terms of operation, everything runs smoothly, with CPU-Z detecting just one of the two 32-bit channels, while the BIOS recognizes 8 GB as the capacity. However, it’s clear that we’re dealing with a 16GB array from G.Skill, but it works as a HUDIMM module in practice.
The results:
In terms of results, the configuration displays read speeds of 32,447 MB/s, compared with 25,195 MB/s for writing and 26,894 MB/s for copying. In contrast, the same RAM, but with its two 32-bit channels active, displays data rates of :
- Read: 58,913 MB/s
- Write: 48,800 MB/s
- Copy: 52,648 MB/s
In actual fact, HUDIMM memory shows reductions of 44.9% in read, 48.4% in write and 48.9% in copy data rates. On the other hand, there is no difference in latency, which remains between 86 and 88 ns.
However, adding two HUDIMM modules achieves similar results to a single UDIMM array. This configuration boasts read speeds of 28,928 MB/s, write speeds of 48,461 MB/s and copy speeds of 51,473 MB/s.
In short, this type of memory should come in at lower prices than conventional UDIMMs, but by how much remains to be seen. Indeed, with performance halved, we’re hoping for a price at least halved too.
