The new Dominators boast new heat spreaders and newer ICs that should result in some nice performance. The series consist of kits ranging from 8GB to 64GB with frequencies from 1600MHz to an incredible hand-tested 2666MHz. We got our hot little hands on a 8GB kit of 1866MHz modules, so we are excited to get to the test phase of this review.

Corsair Dominator Platinum 1866MHz 8GB Kit Review


Today, we will be taking a look at some of the most talked about memory this year. That would be the new Dominator Platinum series from Corsair. Corsair has had an outstanding year this year with the introduction of new cases and solid state drives but it is good to see them get back to what started it all and that is ram.

Closer look

The new Dominators are so awesome to look at. When first opening the packaging I spent a few minutes just staring at the modules. They look as if they were valuable pieces of jewelry that should have been delivered by a tall man in a black suit with a metal briefcase handcuffed to his wrist.

Physically speaking there is a lot of changes with the new Dominator than series past. The first thing of notice is the metal light bar that spans the top of each module. Normally, we would to either purchase heat spreader the color we want or simply buy memory based on the color we want to match our system. Corsair designed the light bar to be removable and replaced with units of other colors.

The rest of the heat spreader which is black in color also takes advantage of Corsair DHX or Dual-path Heat eXchange cooling technology for better efficiency and cooling performance. It is also one of the reasons why Dominator ram has been able to run such high clock and low timings.

One thing these have in common with the older series of Dominators is the array of fins at the top of the modules and the Corsair sails logo and there is where the similarities stop. The main part of the heat spreader seems to be two individual pieces mended together to make it one larger heat sink. Besides the sails there is a P/N sticker with a brief description of the modules one side and the words Dominator Platinum on the other.

One thing that is definitely out of the norm here is sitting on one end of the modules. It is a small interface that will interact with Corsair’s Link system allowing the user to monitor the IC temps and activity real-time.

The overclocking of the 1866MHz speed of the Corsair Dominator Platinum wasn’t too difficult. We started at the default XMP timings and up the memory frequency to the next one available within the BIOS of the Asrock Z77 OC which was 2000MHz. This was a no go no matter the voltage. So, we were determined to get something more out of the sticks, the next step was to play with the BCLK a little. We needed a starting point so we elected to jump right to 102MHz. No problem. We pushed it a little and went straight to 105. No problem once again. At this point we figured we would take baby steps from here on forward. 105.5, 106, and finally 106.5 was our maximum frequency using the default XMP timings and voltage of 1.5.



AIDA64 Extreme Edition
“FinalWire Ltd. today announced the immediate availability of AIDA64 Extreme Edition 1.50 software, a streamlined diagnostic and benchmarking tool for home users; and the immediate availability of AIDA64 Business Edition 1.50 software, an essential network management solution for small and medium scale enterprises.
The new AIDA64 update implements AVX-optimized benchmarks for the upcoming Intel Sandy Bridge processors, adds a brand new video encoding benchmark, and supports the latest AMD and nVIDIA graphics processors.”

Super PI Modded 1.5
“In August 1995, the calculation of pi up to 4,294,960,000 decimal digits was succeeded by using a supercomputer at the University of Tokyo. The program was written by D.Takahashi in collaboration with Dr.Y.Kanada at the computer center. This record should be the current world record. (Details are shown in the windows help.) This record-breaking program was ported to personal computer environment such as Windows NT and Windows 95. In order to calculate 33.55 million digits, it takes within 3 days with a Pentium 90 MHz, 40 MB main memory and 340 MB available storage.”

Flying Wild Hogs Hard Reset
“Thee world as we know it ceased to exist. Humanity is at the verge of extinction, living in the last closed city of Bezoar. Mankind wages war against the machines controlling vast areas of what became the 'Barrens'. Machines want to control and assimilate 'The Sanctuary' a network that holds billions of digitalized human minds. Our hero, Maj. Fletcher, is a soldier of CLN - a corporation combat unit, established to protect the city. Machines are constantly assaulting the walls of Bezoar. Fletcher moves in when Bezoar's protective barrier is breached.”

FuturemarkPCMark Vantage
“PCMark Vantage is a PC benchmark suite designed for Windows Vista offering one-click simplicity for casual users and detailed, professional grade testing for industry, press and enthusiasts.
A PCMark score is a measure of your computer's performance across a variety of common tasks such as viewing and editing photos, video, music and other media, gaming, communications, productivity and security.
From desktops and laptops to workstations and gaming rigs, by comparing your PCMark Vantage score with other similar systems you can find the hardware and software bottlenecks that stop you getting more from your PC.”

MaxxMEM 2
“Is the *little brother of MaxxPI², it contains the same Memorybenchmark routine as MaxxPI² does.
So your reaced results will be comparable to Memory / Latency benchmarks done by MaxxPI².”


Corsair really never ceases to amaze me when it comes to new products and new product development. The Corsair Dominator Platinum 1866MHz is one fine example of that. The pure visible appeal the memory modules have is great. Yes, the heat spreaders are a little large and heavy but the cooling effect as well as the lighting is functional but yet pleasing to look at.

Adding lighting to a set of memory is not new but what makes it better here is the lighting can be switched out to better match the theme of your rig. And the new lighting will be available from Corsair pretty soon.

The set we received will not break any overclocking records but if you want to run tight timings with a little boost in frequency while maintaining a low voltage input look no further than this kit right here. Close to 2000MHz with the timings of 9-10-9 at 1.5v is nothing to sneeze at.

The Corsair Dominator Platinum 1866MHz can be had for about $90 from online retails like Newegg.
