Kingston HyperX DDR3-2000 CAS 8
Update: Kingston had not officially named its DDR3-2000 CAS 8, 6 GB, triple-channel kit when it shipped samples to us as part number KHX16000D3T1K3/6GX. These were officially renamed KHX16000D3ULT1K3/6GX during CES week, but the company did not inform us until after the review was published. We will edit content where appropriate, but the as-shipped name remains in performance charts.
Two days after the memory arrived, one of Kingston’s competitors called to let us know that 2 GB modules at DDR3-2000 would be impossible to produce when limited to a maximum of 1.65 V. We’re guessing that means Kingston walks on water, since the company was able to top that specification with CAS 8-8-8-24 timings. On the other hand, Kingston still hasn’t delivered the modules to retailers.
A maximum SPD value of 667 MHz (DDR3-1333) indicates that these are probably made of slower parts with a high-level of overclock-capability. Users who want to configure their systems to the memory’s rated specification must do so via manual BIOS configuration, while an XMP-2000 profile reduces the number of steps required to set it up.
Kingston memory products carry a limited lifetime warranty.
Mushkin Enhanced DDR3-1600 CAS 7
Mushkin was one of a few companies that sent its product before the packaging was finished, but these individually-packaged modules are the same components found in its retail part number 998679 triple-channel kit.
Mushkin was also the only company in today’s comparison to bolster its DDR3-1600 parts with CAS 7 timings. What makes the tighter timings impressive is that Mushkin didn’t have to lower capacity or raise voltage to get there. The Core i7 theoretical voltage limit of 1.65 V also assures that these modules will stay cool with nothing more than a little extra heat spreader area at the top.
A maximum SPD speed of 667 MHz (DDR3-1333) at 9-10-10 timings again hints at the possibility that the chips used may not be true DDR3-1600 parts, and this appears to be a trend among most brands. But unlike other brands, Mushkin didn’t add an XMP value. XMP-capable motherboard users must follow the same steps as everyone else and adjust speed, voltage, and timings manually to reach the specified performance level.
Mushkin provides a limited lifetime warranty on all its memory products.

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.
From ArticleOf 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).Reply
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.Reply
Good info. Would have been nice to see at least one real world benchmark.Reply
Great article. Thanks.Reply
Anyone know the difference between the followingReply
Kingston HyperX T1 Series Kits:
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.'Reply
I loled at that.. maybe it's too early in the morning for me :D
Interesting just how few people give a damn about DDR3 at this point.Reply
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.
