Corsair has introduced a limited edition memory kit rated at 3000 MHz.
Corsair launched what it boasts to be the world's fastest rated production PC memory kit: the new Vengeance Extreme 8 GB dual-channel DDR3 kit. The kit's two 4 GB memory chips are rated at a blazing 3,000 MHz (air cooled), and fitted with low profile "Corsair Racing Red" heat spreaders. They also have latency settings of 12-14-14-36, at 1.65V.
"The extreme-speed 3000 MHz rating of the Vengeance Extreme memory kits is the result of a rigorous internal four-stage hand-screening process performed by Corsair engineers," the company said. "This process is passed by fewer than one in 50 memory ICs. Performance qualification is performed on select Intel Z77 based motherboards, including the ASUS P8Z77-I DELUXE and ASRock Z77 OC Formula."
To hit their rated speeds, the modules require an unlocked third-generation Intel Core processor with an Integrated Memory Controller capable of running 3,000 MHz. However, speed freaks will be treated to a Kingpin Cooling memory cooler, which is included for overclockers who want to use LN2 (liquid nitrogen) to reach memory speeds well beyond 3,000 MHz.
"There's a reason why world-champion overclockers, extreme gaming enthusiasts and high-end system builders all trust Corsair for high-performance memory that they can install with confidence and pride," the company said. "Whether you're breaking your own records or you're simply building a dream gaming rig, you can count on Corsair memory."
As expected, the Vengeance Extreme 8 GB dual-channel DDR3 kit won't come cheap, costing a hefty USD 749. Corsair said these super-fast memory chips are hand-built, so quantities will be extremely limited. That said, the new kit will be made available exclusively from Corsair sometime in March, so stay tuned.

Even if it did, it wouldnt be economical. You can build a whole better system at the cost of the RAM itself. Still, it would be interesting to see the gains of such fast memory on an APU.
$749.99
Probably the gains are massive but @ this price they are pointless....
"Coarsair said these super-fast memory chips are hand-built"... uh huh. With inhuman soldering skills.
they already have on here and it does help a little bit but anything over 1866 there was only a slight boost in fps. its the lower latency settings that really give you a bigger boost
Remember ? I'm gonna go with "kinda, not really, who cares, save your money and put it towards GPU".
Maybe its Super Human solders =) with computer precision
AMD's APUs got benchmarked with RAM at least up to 2400MT/s and there was almost no improvement with going over 2133MT/s. It seems unlikely there would be much if any gains to be made from bumping rates to 3000MT/s on current APUs... certainly not any that could justify the huge price premium on those DIMMs.
The "latency settings" generally do not give that much of a boost. That's why GPU memory is always focused on bandwidth over latency. Latency does matter, but it is almost always less important than bandwidth.
According to Tom's, it's not until after DDR3-2133 where there is a serious cut-off in performance for the top Trinity desktop APUs gain and even then, it might have been a different issue than the GPU not being able to take advantage of greater memory bandwidth.
The importance of latency varies depending on workload-specific access patterns.
Most heavy computational workloads like rendering, transcoding, physics simulations, etc. lend themselves pretty well to long read/write stripes on RAM and will heavily favor bandwidth over latency like GPUs do.
Heavily conditional (branchy) code like compilers, control code for interactive applications, algorithms that rely on sparse arrays, trees and other branchy structures, cache misses are far more common and these scenarios will heavily favor low latency.
