Test Results: Overclocking, Bandwidth And Latency
We began the competition with an overclocking comparison. Kingston was the only company able to provide DDR3-2000 samples before our deadline, so we expected them to take a lead, while Corsair was the only company to provide DDR3-1866. Will any of today’s DDR3-1600 kits beat Corsair's parts?
Indeed, three DDR3-1600 module sets did overclock further than Corsair’s DDR3-1866 did. Crucial Ballistix continues its overclocking dominance by coming up just shy of DDR3-2000, with Mushkin Enhanced falling only slightly behind. Value-performance brand Wintec also surprised us with a significant 21% overclock.
Update: Kingston renamed its KHX16000D3T1K3/6GX kit to part number KHX16000D3ULT1K3/6GX, informing us of the change after this review was published.
Originator of low-voltage DDR3-1600, Aeneon unfortunately even fell behind the DDR3-1333 set of today’s comparison.
Sandra Memory Bandwidth almost perfectly reflects the speed each module set achieved, but slight variability in this particular benchmark did mix the results of some close contenders.
Most people won’t push their memory to the highest possible speed but will instead use the above information as a guideline for limits. At any given speed, tight timings offer improved performance. We tested each 6 GB triple-channel kit at the three most common "performance" speeds.

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.
