A-Data, Chaintech, and Super Talent
Today’s comparison is among four gigabyte dual-channel kits consisting of two 2 GB modules. Three memory vendors instead sent us two gigabyte (2 x 1 GB) dual-channel kits. Because they have fewer or simpler components, lower-capacity modules often support higher speeds and lower latencies than their higher-capacity counterparts. Thus, we weren’t able to test these smaller kits against the 4 GB offerings in our roundup. Nevertheless, they’re notable offerings that we still wanted to include.
With latencies of 7-7-7-20 at DDR3-1600 and 1.75-1.85 volts, A-Data’s Vitesta X-Series DDR3-1600 modules could have been contenders, had the company only sent its 2 x 2GB kit. During a brief overclocking test, its 2 x 1 GB kit reached a data rate of 1784 MHz at 1.90 volts CAS 9.
Walton Chaintech offers a great many DDR3 performance kits, but only produces 2 x 2 GB GT Blazer kits at a higher DDR3-1800 rating. Its DDR3-1600 kits only come in 2 x 1 GB capacities, and the samples they sent are rated at admirable DDR3-1600 timings of 7-7-7-18 at only 1.60 volts. A brief overclocking test achieved 1656 MHz at CAS 9, revealing that increased latencies don’t give the modules much room to overclock. We tested these at 1.60 volts, because increased voltage didn’t help us to go any further. Our samples wouldn’t even boot at the 1.90 volts we’d normally use for overclock testing, but the lower required voltage is good news for anyone seeking energy-efficiency at relatively high speeds and tight timings.
Featuring fancy cooling and aggressive timings, Super Talent’s ProjectX lineup shows plenty of promise. However, ProjectX isn’t available in DDR3-1600 2 x 2 GB sets, and therefore unable to compete in the benchmark component of our roundup.
Rated at superb 7-6-6-18 timings for DDR3-1600 speed at 1.90 volts, we were able to push these to an equally impressive 1808 MHz data rate by increasing latencies to CAS 9.
