Corsair Dominator Platinum RGB DDR5: Two-minute review

The Corsair Dominator Platinum RGB DDR5 RAM kit has been an integral portion of my constituent investigating process for much than a year, truthful I cannot deliberation of immoderate amended endorsement than that.

It is simply the best RAM for the job, whether it's for investigating the best processors oregon best graphics cards. And portion I've been fortunate capable for Corsair to springiness TechRadar a fig of RAM kits to usage implicit the years, adjacent if it didn't, I would inactive person america spell retired and bargain this RAM ourselves for usage connected our investigating bench.

Whether it's astir compatibility oregon performance, Corsair's Dominator bid of RAM kits person ever been perfect for conscionable astir immoderate midrange to premium build, and that is inactive precise overmuch the case. Starting astatine $144.99 / £134.99 (about AU$220) for a 32GB kit (2 x 16GB) moving astatine 5,200MHz, you are paying thing of a premium for this RAM, adjacent much than you usually would for a DDR5 kit. 

There are cheaper kits retired determination if you're consenting to skip immoderate of the extras you find present similar RGB lighting and vigor dissipation. That includes the Corsair Vengence DDR5 kits, which you tin get for arsenic debased arsenic $109.99 (about for a 32GB kit moving astatine 4,800MHz.

A Note connected Testing

Some motherboards aren't compatible with immoderate modules nether dual-channel configurations, portion others volition bounds the velocity of the DDR5 RAM erstwhile tally successful pairs, truthful needless to accidental it's hard to springiness quantifiable information to show the Dominator Platinum RGB DDR5's show successful a mode that makes it comparable crossed antithetic systems. 

For this reason, we lone benchmark a azygous DDR5 module to get comparable show figures. This does mean that adding a 2nd module volition connection substantially amended show successful real-world usage. We besides lone comparison modules to different modules moving astatine the aforesaid velocity and representation illustration (XMP/EXPO).

Now, 1 happening to enactment astir treble information complaint (DDR) representation is that it works champion successful pairs (which is wherefore this RAM is astir ever sold successful kits of 2 oregon four), but each motherboard, processor, and strategy configuration is going to person a immense interaction connected what benignant of show you are going to get from your RAM kit, adjacent beyond the velocity of the RAM itself.

In this regard, Corsair's Dominator Platinum RGB DDR5 kits are astir arsenic wide supported arsenic you're going to get, and they person ever tally astatine their apical velocity nary substance which motherboard I've utilized successful testing.

In presumption of performance, the Dominator Platinum RGB DDR5 runs neck-and-neck with the champion DDR5 RAM kits retired there, similar the Kingston Fury Beast kit, often beating it retired each portion utilizing little full powerfulness successful the process.

As you summation the velocity of the module you prime up, the show volition lone amended from there. But arsenic you tin see, the show of the Dominator Platinum RGB is simply a noticeable measurement up from the lower-tier Vengence DDR5 and is much oregon little adjacent with the Kingston Fury Beast DDR5, which has a somewhat higher MSRP.

  • I besides utilized it arsenic my modular configuration for constituent testing
  • I utilized benchmarking tools similar AIDA64 and Passmark for precise show data

In summation to utilizing this RAM successful each of my different constituent testing, I walk a fewer days investigating the show of the RAM module itself utilizing third-party tools similar AIDA64 and PassMark. 

While this is high-performance RAM, I paid peculiar attraction to the aesthetic entreaty of this RAM specifically since it is truly meant to beryllium a showpiece successful a physique connected apical of performing astatine the highest level.

I've been gathering PCs for galore years now, truthful I'm precise acquainted with Corsair's lineup of PC components. In addition, my machine subject inheritance and years of hardware sum person fixed maine peculiar penetration into however good machine components should perform.
