Corsair DDR3-1866 CAS 9
The fancy heat spreaders of Corsair Dominator modules were originally developed to cope with high temperatures that normally accompany high-voltage overclocking, yet the firm now offers the same product line in a lower-voltage kit. The benefits of such extreme cooling at 1.65 V operation are questionable, but performance enthusiasts will certainly exploit even the tiniest benefit to reach their goals.
Hoping its part number TR3X6G1866C9DF, 6 GB DDR3-1866 triple-channel kit would automatically configure to at least DDR3-1600, we found a maximum SPD value of DDR3-1333 at standard voltage. Intel’s XMP extensions take over from there, allowing semi-automatic configuration at the kit’s rated DDR3-1866 speed and 9-9-9-24 timings, using a Core i7-friendly 1.65 V.

Crucial Ballistix DDR3-1600 CAS 8
We received Crucial’s Ballistix 6 GB DDR3-1600 triple-channel kit before the company had come up with any retail packaging, but its use of a white box had no bearing on the quality of the parts within. Part number BL3KIT25664BN1608 didn’t even have a name yet when Crucial shipped these parts as three separate BL25664BN1608 modules, and these are among the firm's first 2 GB DDR3 Ballistix products.
A subsidiary of memory fabricator Micron, we had to wonder what took Crucial so long to develop a product that its competitors had long been selling using the same Micron parts. Was the company simply waiting for Core i7 to push DDR3 to the forefront?
An SPD automatic configuration max speed of 667 MHz (DDR3-1333) at stock voltage indicates that even Micron is probably using slower "overclockable" chips to reach higher speeds, and testing proved that the second XMP value of DDR3-1600 CAS 7 is unrealistic when the memory is in triple-channel mode. It was, however, able to exceed its rated 8-8-8-24 timings at DDR3-1600 and our tests will show how far it can really be pushed.

Grate article!
What was always bothering me about ram reviews is how much memory speed/timing will really impact on system performance. I it is a lot of work I know, but it was never covered.
Of course, we needed a Core i7 processor, but not just any processor would do. While most reviewers are stuck with engineering samples that only support DDR2-800 and DDR2-1066 ratios (3x and 4x base clock, times two), our retail sample supports data rates all the way up to 2,133 MHz (8x base clock, times two).
I could be wrong, but shouldn't it be ddr3 ? I'm not aware of i7 supporting ddr2?

Heheh, looks like it's been edited.
I wounder if amd will do quad channel with its am3 motherboards or even dual 128 bit channels. that would be cool. Just something to beats intels triple 64bit channels.
Mushkin FTW
Lattely, I have noticed that Cosair has slowely slipped down (*cheering*), it seems they have gotten way to comfortable and now their products are showing that. This isn't the first time I've seen a high-priced *high-performance* Cosair product get absolutely trashed in comparisons by cheaper brands.
Cosair is going the way of Sony and Dell. "We got a name so were not gona do any more work on making our products better, exept to make them cost more so we can have more money!"
Good info. Would have been nice to see at least one real world benchmark.
Great article. Thanks.
Anyone know the difference between the following
Kingston HyperX T1 Series Kits:
KHX16000D3T1K3/6GX
KHX16000D3ULT1K3/6GX
What does the UL signify?... would it benchmark the same as the former (which was tested in this article)?
'The current problem is one of voltage.'
I loled at that.. maybe it's too early in the morning for me
Interesting just how few people give a damn about DDR3 at this point.
I guess many are a: Not wowed by i7 like they were core2 and b: Laugh and the prices of DDR3 at a time when DDR2 is not only still very fast relative to the software/games on the market but is dirt cheap.

They may have changed the name.
The response I got from Kingston:
=======================================================================
Kingston part number KHX16000D3ULT1K3/6GX is a DDR3 PC3-16000 memory module running at 2000MHz.
Kingston part number KHX16000D3T1K3/6GX is not a valid Kingston part number. Did you mean to ask about Kingston part number KHX16000D3T1K3/3GX?
=======================================================================
Either Tom's had a typo, and this is really only a 3GB (1GBx3) kit, or it is not released for resale yet (e.g. the sales reps don't have that part number available to them). The *only* 6GB kit I saw had the UL designation.

I guess now you want a copy of the invoice? Tom's didn't make a mistake, but it's possible Kingston might have changed the part number after sending the kit.
In CPU reviews it is often pointed out that the overclockability of any particular CPU depends on the particular CPU sample, and that results may differ strongly between CPUs of the same model. Why does this not apply to memory modules?
nah, not harping on mistakes or anything, just that Kingston is saying they do not have a 2GBx3 kit with those series available.
Reason I'm asking: Building a new system this week and looking to purchase THIS ram (the Benchmark champion, Kingston HyperX T1 series 6GB kit per this article).
I know the article said you can't find this anywhere, I was merely asking Kingston for when this ram might become available.
mushkin FTW again great price/performance value as always
Tom's,
But what about performance in areas that count? I want to know if DDR3 2000 gives me more FPS than DDR3 1066 in games (Crysis, COD: WaW, FC2, etc). Because what I've seen so far, the answer is no or very very little.
In CPU reviews it is often pointed out that the overclockability of any particular CPU depends on the particular CPU sample, and that results may differ strongly between CPUs of the same model. Why does this not apply to memory modules?
It does apply to memory modules, but to a lesser extent. If you overclock six sets of modules with identical specs, you usually get a varience of around 20MHz.

Because both are rated at 2000 MHz CAS 8-8-8 1.65V, the most likely scenario is that Kingston sent its test module set to THG first, then altered the model number BEFORE making them available. That would mean the original model number never even made it into the stocking system. Since that's the most likely scenario, I wouldn't have any problem buying the parts with the UL designation.
coolio! Thanks Crashman!!!
Wonderful. Nice Article.
I are preparing a XY chart with Price-Performance based on that data, to post here soon.
Now, This article need a second part, Real world benchmarck, and bus overclocking limits on the wonderful P6T Deluxe.
