At all times and measurements, the system baseclock and multiplier will remain the same, meaning each and every difference you spot on performance is a direct results of changed memory frequency and timings.
Sandra Memory bandwidth
SiSoft Sandra has a fairly interesting memory benchmark suit which allows us to monitor memory bandwidth.
Today we'll be using an X58 chipset motherboard on which we plant a Core i7 965X processor. We'll leave this processor at reference clocks.
The only thing we'll be changing today are DIMM modules, frequencies and memory dividers. The Core i7 will run at all times at it's default clock, so that will not show any effect on performance.
Okay so for the first round of tests, synthetic testing. Here we have the read performance of the memory kit at that 1600 MHz default and 1866 MHz (OC) frequency.
Then you need to compare to the very same setup, yet with JEDEC timed triple channel memory at 1066MHz - 3GB, 6GB at 1066MHz, we also threw in the results of a 6GB kit at 1600 MHz.
Most of these setups these days all run either 1066, 1333 or 1600 MHz depending on their baseline settings. Most Core i7 / X58 entries for example run triple channel memory configurations at 1066 MHz (default). Intel's Nehalem architecture and specifically here, the memory controller just hauls ass.
So all kits are triple channel, and as you'll observe, throughout the test session the Corsair memory obviously leads.
Memory Read test
Above AIDA at work with the memory read test. You'll notice that at 1600 MHz we reach almost 17 GB sec of bandwidth, which is stunning.
Memory Write test
Write performance then -- For comparisons sake, a Phenom II processor will perform roughly in-between 6500 and 7000 MB/sec -- with sharp timings you'd take it to roughly 7500 to 8000 MB/sec. In triple-channel mode Vengeance reaches an astonishing ~14400 MB/sec at 1600MHz.
Corsair H75 review In this review we test the Corsair H75 liquid cooler. The H75 features a 120 mm radiator that is a good 25mm but also was applied with two really silent low RPM fans, so you add this kit in a push-p...
Corsair H105 review We test and review the Corsair H105 liquid cooler. The H105 features a 240 mm radiator that is thicker then normal, with a 38 mm thickness. As comparison the H100 uses a 27mm tick radiator....
Corsair Obsidian 250D review We review a new chassis from Corsair, it is the Obsidian 250D. A small mITX form factor ready chassis that will house the smallest, but also the biggest stuff inside your OC. Not mid, not full, mini and this...
Corsair RM650 Watt Gold PSU review We review the Corsair RM650 GOLD power supply. Yes, the silent and a bit mainstream RM650 is now Gold certified, that means it's 90% efficient at 50% load. Efficiency matters. The PSU itself is partly modular, for most of you with a side panel window in their chassis a must really as you'll want modular cables. The new PSU also improved on the audibility front. Have a peek at the article.
