Corsair Dominator Platinum PC3-17066 C9 2x4 GB (CMD8GX3M2A2133C9)

The true overclockers will only be concerned in memory with working capacity at frequencies above 2 GHz. The CMD8GX3M2A2133C9 kit is an example, but you have to be aware that the prices of such products increase quickly along with their rated frequency. For instance, the DDR3-2133 Dominator Platinum kit is more expensive than the DDR3-1600 and DDR3-1866 series of the same capacity by 40%.

The dual-channel 8GB CMD8GX3M2A2133C9 kit is prominent in the Dominator Platinum series since it has a CAS Latency of 9 and a voltage of 1.5 volts while having the higher frequency speed. The faster products in the series have got a worse CAS Latency and a higher default voltage. Alternatively, the CMD8GX3M2A2133C9 is not as good as the products having the lower speed of timings. The timings of this kit are 9-11-10-27.



In addition to the specifications, we can note the version number in the stickers. The components will be different again. Version 4.13 represents Samsung chips which are not very common in the memory modules for enthusiasts.

The initial marking is maintained on the chips of DDR3-2133 kit. As you can see, the CMD8GX3M2A2133C9 modules use HCH9 chips of Samsung; these chips are often used in the overclocker-friendly products, some of which are pretty impressive.

The XMP configurations of CMD8GX3M2A2133C9 modules are recorded according to their specifications. The ability to install similar compatibility SPD with other products mentioned in this review.

Corsair Dominator Platinum PC-19200 C10 2x8 GB (CMD16GX3M2A2400C10)

Considering the low cost of the system memory, many enthusiasts prefer to buy memory kits bigger than 8 GB. We also have a product like that. The 2x 8GB CMD16GX3M2A2400C10 kit is not different from the same 2x4GB series in an intuitive way. For example, although some applications may require as much as 16 GB of memory, you can use some more for a RAM disk. Therefore, the 16GB kits are an option.



For the specifications of the product you see in the photo, its timings make up less than the modules discussed above, while its default voltage grows up to 1.65 volts. This is due to its higher rated speed (DDR3-2400) than the capacity. The timings of 10-12-12-31 and voltage increase are also recorded in the specifications of the 8GB kit.

The version number on the sticker is 4.21. It represents Samsung's chips which are the same as the chips in the CMD8GX3M2A2133C9 kit but with the double capacity.

We might check this by dismantling the module. The Samsung HCH9 chips are the same series as the components of the CMD8GX3M2A2133C9 kit.

As planned, the XMP configuration describes the DDR3-2400 mode and the stipulated timings with a voltage of 1.65 volts which is supposed to be a peak safe voltage for modern Intel platforms.

Please note that the secondary timings of CMD16GX3M2A2400C10 kit are higher than the other products in this review. This is thanks to the large capacity, so the 16GB Dominator Platinum kits are slightly slower than their 8GB counterparts. However, you will see this briefly in our experiments.

Corsair Dominator Platinum PC 21,300 C11 2x4 GB (CMD8GX3M2A2666C11)

We have never tested the ability of the kit in the working DDR3-2666 mode. It is a very high speed that can only be achieved through a combination of many factors. It does not even depend entirely on the memory manufacturer and such things as a choice for the best chips as good PCB wiring and efficient cooling. The mainboard and memory controller are also marked. Anyway, Corsair decided to sell not only DDR3-2666 SDRAM, but also DDR3-2800 in the Dominator Platinum series. We have the dual-channel 2x4GB kit CMD8GX3M2A2666C11 for our experiments.



Releasing the fast memory is similar, the manufacturers often provide a list of compatible motherboards but Corsair does not provide any information at their official website such as the motherboards that CMD8GX3M2A2666C11 modules support at their full speed. Therefore, if you buy a fast memory kit, you have to trust that the CPU and motherboard can fit it. The CPU must be in the overclocker-friendly K series and the motherboard must not be entry-level.

The DDR3-2666 modules look like their previous series. You can only recognize them by the high frequency written on the label and the high timings (11-13-13-35). Of course, the voltage is 1.65 volts. The 5.12 version number means that Corsair has a different type of chips for each speed: the high-speed products are based on Hynix components.

These are Hynix H5TQ2G83CFR-H9C chips which are often likely to be found in overclocker-friendly DDR3 memory modules.

There is only an XMP configuration for the CMD8GX3M2A2666C11 kit. It describes the DDR3 2666 mode which is specified with the timings of 11-13-13-35-2T and a voltage of 1.65 volts.

We think that a second configuration with a lower frequency and more aggressive timings will be appropriate, but the Corsair engineers seem to imply that DDR3-2666 is common enough and unnecessary to use that.
