Can your Intel Core 12 handle these DDR5 RAM? 6,600 MHz!

DDR5 memory is no longer a promise of the future, but a palpable reality with motherboards and processors that support it as well as memory modules that are already being manufactured. This is the case of memory kits Trident Z5 RGB from G.SKILL stand out above all for a lower latency compared to other fifth generation DDR memories, to the point that they achieve the first DDR5 of 6,600 MHz with Cas 36!

One of the most important points when it comes to CPU performance is memory latency, which has a strange relationship to bandwidth. If the latency is very high then the effective bandwidth ends up being reduced and the reason for this is very simple, each access to the RAM has to be managed and any delay in this work ends up delaying the rest of the packets. At the same time, a huge bandwidth can create an environment where it cannot be managed by itself.

DDR memories for RAM differ from GDDRs for VRAM by having less bandwidth, but a latency that is not exaggerated and is that every contemporary central processor in a PC is sensitive for its performance to latency. Unfortunately the access times from the CPU to the RAM in the case of DDR5 are higher than in the previous generation and this is done in order to increase the transfer speed between both parties.

This is the Trident Z5 RGB memory from G.SKILL

G.SKILL has just presented a new kit of two DDR5-6600 memory modules that make use of Samsung memory chips and therefore can reach 96 GB / s of dual channel bandwidth, with a capacity of 16 GB per module, but where it especially stands out is in its access latencies, since they are from 36-36-36-36 instead of being 40-40-40-40 as in standard DDR5.

With regard to access to RAM by the CPU, the latter does not make a simple request, but rather a series of ordered accesses that must be carried out within a specific time, which in the case of DDR5 is 40 memory clock cycles, the advantage of G.SKILL Trident Z5 RGB memory is that the memory performs those operations in 36 clock cycles much faster and this reduces the time it takes for instructions to execute, making the system benefit from the use of the Trident Z5 RGB compared to standard modules.

The Trident Z5 RGB modules come mounted in a package that includes the classic Trident series heat sink (now improved), RGB support to match the configurations that integrate this type of lighting in their general aesthetics and are presented in two versions: completely black or silver. So we are facing a type of memory designed for those who seek the highest performance in their PCs and are therefore willing to pay a little more.

DDR5 memory designed for the future

Trident Z5 RGB

The first CPUs with DDR5 support are the Intel Core 12 with Alder Lake-S architecture and AMD Ryzen APUs with Rembrandt architecture, the first in a few weeks and the second is already being manufactured and like the rest of AMD APUs will be presented at CES officially to be launched after a few weeks or months after that.

The common point of both architectures with respect to DDR5? How much they support DDR5-4800 in a 1: 1 communication and therefore to be able to communicate with faster memories they need to put their memory controller in 1: 2 mode and cut their communication speed between the interface of the CPU and the RAM by half adding latency. So the use of these G. SKILL modules help to alleviate this loss of performance and keep in mind that we will see similar models and other brands.

That is why we say that this Trident Z5 RGB is a memory designed for the future, which is normal, since like DDR4 to DDR5 we will have it with us for several years.
