Introduction and DDR3-1,066Take a look at our 'what-you-should-pay-for-DDR2-RAM article' if cheaper DDR2 is of interest to you. Here we're looking at DDR3 pricing in late November 2008.
DDR3 scales higher than DDR2 and is supported on enthusiast-oriented, Intel-based chipsets only, including Intel's X38/X48, a few P35s and P45, and NVIDIA's nForce 790i (Ultra) SLI.
With Intel launching Core i7 processors earlier this month and now available in retail form, the DDR3-only platform, comprising of the CPUs and X58 motherboard, should provide a shot-in-the-arm and catalyst for dropping DDR3 prices. AMD, too, will move on to a DDR3 memory-controller with a range of Phenom II X4 CPUs early next year, we believe.
DDR3's Achilles Heel has always been price, with a 4GB DDR3-1,333 pack costing around 3x a DDR2-800MHz's in late May 2008, but let's now see if this has changed in the last six months.Intel's Core i7 uses a tri-channel memory-controller that is best outfitted with either 3GB or 6GB of DDR3 memory, so that's why you see odd-numbered sets listed below. Further, the controller is sensitive to voltage adjustment because it's located right on the CPU. That's why Core i7-optimised kits run with lower-than-normal voltages. However, there's nothing stopping an enthusiast purchasing a kit and then using it on a non-Core i7 platform, albeit with potential modules spare.
We'd normally forgo looking at DDR3-1,066MHz kits because the improvement over low-latency DDR2-800 memory is minimal. However, with you-know-what (Core i7) officially supporting the speed the majority of memory manufacturers have released appropriate tri-channel kits.

Crucial appears to own the DDR3-1,066MHz space with a range of regular and Core i7-optimised kits at keen prices. Note, however, that basic DDR3 is still 2x the cost of comparable DDR2 - £102 vs. £55 for a 4GB kit.
