Corsair Dominator GT DDR3 Memory Hits 2533MHz, Sets World Record for DDR3 Frequency

Corsair, announced today that Corsair Labs has set the world record for DDR3 frequency on a Core i7 system. Corsair Labs achieved an astounding speed of DDR3-2533MHz with the aggressive memory timings of 7-8-7-20 using a triple-channel 6GB memory kit. This new world record, verified and validated by CPU-Z, the industry-standard tool for verifying overclocking results, is the first time this frequency has been achieved on a Core i7 system with 6GB of memory using three modules; most world record attempts use only a single 1GB module. Corsair Labs engineers used the award-winning Dominator GT 2000C7 memory with eVGA’s X58 3X SLI Classified motherboard to shatter the world record for memory frequency. Validated results and setup details can be viewed here.

“When it comes to overclocking and memory, Corsair has proven—once again—that its engineering team truly is the best”, said Kevin Conley, Vice President of Engineering for Corsair, “As the new world record shows, Corsair’s modules are second-to-none in terms of performance, stability and quality.”

Corsair Labs selected the new EVGA X58 Classified motherboard for setting this new world record, along with a Corsair HX1000W power supply and the newly-announced Corsair Storage Solutions P256 SSD, creating a system truly designed for maximum performance.

“eVGA is thrilled to learn that Corsair was able to set a new world record memory frequency on our motherboard. Our goal was to create the best overclocking motherboard on the planet for Intel Core i7 processors and these results prove it,” said Joe Darwin, Director of Technical Marketing at eVGA, “When paired with Corsair’s ultra-high performance Dominator GT memory, we’ve not only met our goal, we’ve blown it away.”

All Corsair Dominator GT modules are built using the patent-pending DHX+ (Dual-path Heat eXchange) heatsink, which uniquely cools both the front and back of the memory ICs, and the printed circuit board, for greater reliability and increased overclocking flexibility. All Dominator GT products also ship with the Corsair Airflow fan as standard, which maximizes airflow over the module’s cooling fins, increasing heat dissipation to improve memory performance and reliability.

DHX+ modules feature removable heatsink fins, which allows for range of Dominator GT cooling options, including the Corsair Cooling Hydro Series H30 waterblock and Ice Series T30 thermo-electric cooler, which actively cools the modules up to 20°C below ambient temperature for maximum overclockability.

wondering what type of cooling on that thing.

There'd be hardly any gains in performance over 1600 though, either way congrats to Corsair.

still running ddr (500) and i'm not impressed by ddr3 not even ddr2

Thats great but

Is it stable? I want to see it pass orthos stress test. Then I will bow down.

damn, and iI thought I was cool when I got these Dominators up to 1220Mhz.. thats just crasy fast!

Benches like that dont have to stress test. Getting a snap shot is all it takes for recognition. Hell a CPU-Z validation is stress enough at those crazy speeds.

thats hella fast and at really good timings!

What voltage...oh yeah, enough to damage the cpu and bake a cake at the same time.

Find what chips they're using, get a set of sticks from gskill with same chips, crank V through the roof and you'll attain the same speed. Corsair, again, does nothing interesting except marketing.

2500MHz of memory, might come in handy...
4.5 GHz CPU
2.5GHz Ram
1.0 GHz GPU

I think we can officially retire the Megahertz.

I would agree with you if they were running high timings, but they aren't. Those are very good timings so it should be a pretty noticeable difference.

That's what i thought! Wander if he could go higher with looser timings, or if he's frequency limited by the motherboard/cpu? He should have some more headroom for the base clock.

Pretty awesome though! :respect:

No impressed

At first I thought those are the default values of some new released memories. OC? Neh, you can keep them. An DDR2-1200Mhz mems with 5-5-5-12 timing leaves those mems to dust anyways...:cool:

erm no LOL...

Those timings are tight for DDR3 and it's TRIPPLE CHANNEL! those things would beat you at 1066mhz! but 2500mhz is insane.

EDIT: your computer is a Dell... I forgive your ignorance on this subject.

lol. You would have to run DDR at 1785Mhz 5-6-5-15 to match the performance of these sticks.

Shame they didn't get an everest latency screenshot in there.

Dude... the 1266 actually means 2512 you know...... Unless you know that... in that case you don't belong in TPU xD

eh? he said ddr2 1200 5-5-5-12, and i agree lol that speed with those tight timings is unpresidented. The best memory on retail clocked at 2ghz on the egg have 7-8-7-20 timings and are by OCZ and G.Skill, though they operate at 1.65v so i wonder if they have the same chips with such low timings at that voltage. Most of the other sets of DDR3 2000 at 1.65 are around 9-9-9-24 timings or so, and then there are still a decent quantity with 1.9-2.0v with 9-9-9-24 or so as well.

Yes, i read him correctly.

Regardless of timings: DDR3 1066 in tri channel > DDR2 1200 in dual channel

I meant 7-8-7-20 is tight for DDR3. 5-5-5-12 is easy on DDR2 1200

But if you think that triple channel are making a diference you are really a n00b. Just check the "wire" for some real tests :banghead:

HAHA! You're joking right??? DDR2-1200 and even DDR2-1066 can only be beaten by very expensive DDR3s. Again, check some test in real applications like games, video encoding, etc. Forgot about the bechmarks, your not playing benchies, right?? :banghead:

Show me one test to prove that! ONE!!! LOL! (using the same CPU and GPU, naturaly ;) )

yea lol i remember lookin up a comparison of ddr2 vs ddr3, and only speeds of 1600mhz+ out did the ddr2 modules, and they only went up to ddr2 1066 was almost on par with ddr3 1333 and outdid ddr3 1066 simply because the timings were so much tighter on the ddr2 modules

How do you use the same cpu for comparison when you can only use a Core i7 for tri-channel DDR3? It won't do DDR2.

As far as your benchmarks vs "real world". I agree that some graphics benchmarks may skew results, but for memory bandwith, more is better. No exceptions.

Anyway, a couple of comparisons using Everests memory benchmark:

DDR2 1200 1:1 @ 5-5-5-10 Duel Channel

Ok, one of my runs. This is pretty much the fastest you will see for DDR2 1200, or not far off.





DDR3 1066 @ 9-9-9-24 Tripple Channel

Yes, but we are talking about DDR3 Tri channel vs DDR2 Dual Channel, there is simply no competition.
