USB 3.0 Backup
Our backup testing takes a typical set of user files – specifically just under 8000 files across 4 GB, some large files but mostly small. For USB 3.0 testing, these files are copied from a 4 GB RAMDisk onto an OCZ Vertex3 which is connected via a SATA 6 Gbps to USB 3.0 device. We use all the USB 3.0 protocols available - the UASP protocol that the ASMedia controller on our test bed affords as well as the chipset driven Intel USB 3.0 under ASUS' Turbo mode. The copy test is conducted using DiskBench, a copying tool with accurate copy timing.
Across the result range, no matter which protocol is used, our copy testing shows up to a 7% decrease in copy times over the USB 3.0 protocol moving from DDR3-1333 to DDR3-2133. In some cases, such as using Intel Turbo mode, the timing levels out around DDR3-1866, but in the case of UASP, the DDR3-2133 C9 kit provides the best result. Interesting to note that in the case of UASP, having a smaller CL value is more important than having a larger speed value.
Thunderbolt Backup
Similar to our USB 3.0 Backup test, Thunderbolt testing carries the same files directly through to our LittleBig Disk which contains two 120 GB Intel SSDs in RAID-0. The copy test is conducted using DiskBench, a copying tool with accurate copy timing.
Thunderbolt tests are never as consistent as USB timing – the results shown are the average of the best three obtained. Typically the best results come after leaving the Thunderbolt device for 30 seconds or longer after the last copy test as the TB device does an amount of post processing after the data has officially been sent. Nevertheless, a gradual decrease in copy times is exhibited from DDR3-1333 to DDR3-2400.

This article is pointless and debating is futile. Everybody knows that ORANGE memory modules are always faster than BLACK one, but not as fast as RED ones! Duh...The same with cars...

you keep saying that a big part of the heat sinks are too "prevent the competition from knowing what ICs are under the hood". do you really think if a competitor or anyone for that matter who wanted to know what ICs were being used are going to say damn we cant find out what the ICs are because the $45 memory has a heat sink? im pretty sure they are going to buy a kit and rip them apart.editorsorgtfo - Tuesday, October 14, 2014 - link
Sean, what a willie-brained banger-spanker you are! You probably still piss in your shorts when you discover that someone you've irked has smeared buggers on the screen of your monitor. "No one gives a shit about APU you moron......these are desktop tests!" I, for one, give a shit about APUs, you lummox, since I am building a top-quality box around an A10 7850K and a G1.Sniper A88X. Gamers who yank a joystick with one hand and wank off with the other aren't the only people that want a kickin' computer. My entire life isn't geared toward FPS, RTS or T, or MMORPG pursuits, nor do I do anything else that is graphics-processing intensive, like video editing, rendering, Bitcoin mining, etc., etc., so I don't need high-powered graphics, beyond what AMD's Dual Graphics with a Radeon R7 250 will achieve. My intent is to use my new APU machine for audio recording, and I'd like to be able to get a really good overall picture of how a Kaveri system will behave using 16 or 32GB of various brands of DDR3 1866 or 2133 CL8 or 9 @ 1.5V or under SDRAM, possibly using AMD's RAMDisk software, with a very good (250GB or larger Samsung 840 EVO or better SSD), and preferably using audio-oriented real and synthetic benchmarks, because Intel has the computer-video-game-playing world by the goolies, and to most gamers, winning is everything, so they go with Intel, never once thinking about how less than 2 decades ago, there was a third big player in the processor world: VIA! They got squeezed out of the desktop competition by Intel and AMD, and we are the worse for it. Anyway, this is not to disparage Ian's testing and write-up for this review (good on yer, mate!), because he used what he had on hand. But you, Sean -- why don't you just keep your witless gob shut if you don't have something interesting, enlighting, thought-provoking, useful, helpful, amusing... i.e., POSITIVE! to contribute? "AMD is a decade behind Intel, in processor technology and instructions, it really doesn't matter what AMD attempts to do...." For f*ck's sake -- get an effing life, kid! Then, maybe you'd finally get laid, and someday, even have a girlfriend and a car, instead of Five-Finger Mary and a skateboard!exodius - Monday, February 2, 2015 - link
You got one of the calculations wrong:DDR3-1866 11-11-11 has a Cycle Time of 1.07 ns and a Bit Time of 0.536 ns
The time to read one word should be 1.08 * 11 = 11.88 ns (not 11.79)
The time to read eight words should be 11.88 + 7 * 0.536 = 15.632 ns (not 15.54)
Unless i'm missing something
