Kingston HyperX T1 KHX21C11T1K2/8X
Of course, there are HyperX T1 products faster than DDR3-1866. One example is the 8GB dual-channel kit HyperX T1 KHX21C11T1K2/8X which consists of two sticks rated for DDR3-2133.
Its specs follow below:
- Dual-channel kit consists of two memory modules, 4 GB each;
- Nominal frequency: 2133 MHz;
- Timings: 11-12-11-30;
- Voltage: 1.65 V.
As you can see, it wasn't easy for Kingston to make the next 266MHz step up. The clock rate is higher but the timings are higher, too. On the other hand, timings are known to have a minimum effect on the performance of modern platforms, so the HyperX T1 KHX21C11T1K2/8X is anyway going to be faster than the above-discussed DDR3-1866 kits, let alone DDR3-1600 ones.
Fortunately, Kingston didn’t consider the overcoming of the 2GHz barrier a good reason to raise the price much higher. The HyperX T1 series products rated for DDR3-2133 and DDR3-1866 differ in price by a mere $3.
Well, this might be expected just because there are a lot of indications of a close relation between these two memory kits. There is no ground for a serious difference in price. Particularly, it is just not easy to tell the DDR3 KHX21C11T1K2/8X kit from the KHX1866C9D3T1K2/8GX. Both are covered with identical heatsinks which are the same color and shape. This isn’t good news, though, because the HyperX T1 heatsinks are excessively large and may cause some assembly-related problems.
The components used for building the KHX21C11T1K2/8X modules are interesting as they look exactly like those of the DDR3-1866 kit from the HyperX T1 series. The PCB design and the marking on the memory chips are identical. Kingston seems to have found the Hynix H5TC2G83CFR-H9A chips a very versatile solution. By simply increasing the voltage of these DDR3L chips and sorting them out according to their frequency potential, Kingston has managed to build a rather extensive product line.
The KHX21C11T1K2/8X kit has two XMP profiles. One of them contains the specified parameters and another describes a failsafe DDR3-1600 mode with 9-9-9-27 timings.
Take note that the profile’s voltage for the 2133MHz clock rate is 1.6 rather than 1.65 volts. It is unclear whether the specs or the XMP profile is incorrect, especially as we had no problems running these modules at either voltage.
