Closer Look: Winchip PC3-10666
The Winchip PC3-10666 CL8-8-8-15 DDR3 kit was developed to offer enthusiasts a memory solution that takes full advantage of the capabilities of the Intel P35, X38, and the upcoming P45/X48 Express chipsets. At 1333MHz, the Winchip 64A0TRHN8G17E DDR3 is presently considered the fastest step in the official JEDEC standard. Since this Winchip kit is rated to run CL8-8-8-15 timings, it is poised to provide enthusiasts with high-performance potential regardless of the bus speed.
Because this 64A0TRHN8G17E kit operates just beyond the 1.5V JEDEC specification at 1.65V, Winchip offers an over-sized heatspreader to keep this PC3-10666 module cool. Some manufacturers such as OCZ set the bar for appearance rather high with their Reaper HPC design, and then lift that bar even higher with their recently announced PC3-10666 ReaperX HPC Enhanced Bandwidth DDR3. I must confide a "secret" to you though, the extra cooling is a waste. I have touched overclocked Super Talent PC3-14400 while it was running at 1852MHz, and it barely felt warm to the touch.
The tall profile used on the 64A0TRHN8G17E kit can cause problems with certain low-profile builds, so system builders should be forewarned. In our recent reviews, the larger heatspreaders found on the Winchip PC2-9600 64A0TMTHE8G17C and Super Talent PC3-14400 W1800UX2GP kits have found themselves too tall to fit in a full range spectrum of system applications. This translates into compatibility in compact computer builds, such as shallow HTPC systems.
During normal operation, I discovered that the Winchip PC3-10666 CL8-8-8-15 DDR3 RAM kit generated a temperature which was hardly enough to warrant the enlarged heatspreaders. DDR3 inherently runs much cooler than DDR2, thanks to the reduced voltage requirements. Standard 1.8V DDR2 kits running at a lowly 800MHz can often be nearly impossible to touch during operation, but this isn't the case with DDR3. The drastic reduction in operating temperature is likely the result of the efficient DDR3 process and the (lower) 1.65V used with this 64A0TRHN8G17E kit.
For those readers who are familiar with the Winchip PC2-9600 64A0TMTHE8G17C DDR2 kit, there is not really much of a difference between this DDR3 design and past generations. Personally, I think that the introduction of a new design to coincide with a newly introduced standard is a good idea, and lets consumers know they are getting new technology. It just doesn't make sense to sell a new product in an old package.
In the next section, Benchmark Reviews covers the finer points of DDR3 and the changes it brings. The overall progress of this DDR3 series is also updated, along with overclocking results.
