Two new models of high-performance RAMs of the Corsair brand, and of its economic series Vengeance, have appeared for sale in Japan. These new RAM memory from Corsair Vengeance DDR4-4800 and Vengeance DDR4-4866 are the most frequently used models for sale for the series of RAM memory Vengeance LPX. Since, until very recently, it had its maximum frequency set at 4,600 MHz.
The new series of high-frequency RAM memories, within the Corsair Vengeance LPX models, will consist of 3 different models:
CMK16GX4M2Z4866C18: 4,866 MHz, 2 x 8GB, CL18-26-26-46, 1.5V
CMK16GX4M2K4800C18: 4,800 MHz, 2 x 8GB, CL18-24-24-46, 1.5V
CMW16GX4M2Z4600C18: 4,600 MHz, 2 x 8GB, CL18-26-26-46, 1.5V
Corsair Vengeance review
As is easy to see, the new Corsair RAM modules have quite high latencies, except for their CAS latency, which is quite contained. However, the Vdimm of the modules is still higher, since they require 1.5 V to function properly. This means that the new memories need an extra 25% voltage compared to the one marked by the official JEDEC specification for DDR4 RAM.
However, DDR4 RAMs like these Corsair Vengeance LPX have been developed so that they can use their large bandwidth. Probably the platform where this bandwidth can best be used is the Intel Core. Which usually prefers, by architecture, this type of memories with more relaxed latencies and high operating frequencies. Although, since the official launch of these new models has not yet been made, we do not know if they can also work properly on the AMD Ryzen platform.
Although the prices of RAM have been falling for a while, the new Corsair Vengeance RAM will not be cheap at all:
CMK16GX4M2Z4866C18: 968 euros
CMK16GX4M2K4800C18: 732 euros
CMW16GX4M2Z4600C18: 390 euros
Taking into account that we are talking about 16 GB (2 x 8 GB) kits, it is clear that these RAM memories are destined for a fairly niche market. Because spending almost 1,000 euros on 16 GB of RAM has, hardly, a simple explanation. And that we are talking about the range of economic models of Corsair.
Even so, the jump in performance from the fairly frequent DDR4-3000 or 3200, to the 4866 MHz of these new RAMs, must be quite apparent in applications that value bandwidth more than low latencies. And, of course, in processor system architectures to which the same thing happens.
As usual with current RAM modules, the new Corsair Vengeance DDR4-4600, 4800 and 4866 are equipped with XMP 2.0 profiles. Thanks to them, users do not have to bother to change each of the parameters inside the motherboard’s BIOS. Simply by activating the corresponding profile, the corresponding changes in the BIOS will automatically be made. But you also have to keep in mind that these high RAM frequencies are not supported by all Intel motherboards and chipsets. Only those of the highest ranges are capable of allowing overclock of RAM.
