Mainstream-Ready? DDR3-1600 Shootout

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.

    Unless you guys know something that I don't (which is perfectly possible), as far as I understand the X58 will have a DDR3-1066 standard, which in my eyes makes DDR3-1333 the more coveted overclocking without breaking the bank. Unless DDR3-1600 makes a REAL improvement in overclocking capabilities (and I don't think it does, isn't that one of the features the IMC is supposed to bring?), I'd like to see more DDR3-1333 round ups, which in my opinion will be the more sought after memory with the masses.

    Rumors are all over the place on the new CPU, with support for up to DDR3-2000 rumored as an option for tuners (read, overclockers). This memory overclocking mode is also rumored to be available at stock CPU speeds.

    Heya emp! It'll officially be doing DDR3-1066 out of the gate. However, you're probably going to see motherboard vendors enabling 1333, 1600, and 2000 as well, which is why we were hoping some of these modules would hit that number with overclocking.

    lacritsI recent the online survey I am promted when trying to continue in the article! There was no way for me to "x"-out the message, I had to answer in the "applet http://en.wikipedia.org/wiki/Applet " itself. I don't trust such content and would like the option to not answer in the applet at all!If I see this crap repeatadly here at Toms when viewing articles or reading other content I'll stop visiting this site altogether.. I've been a frequent visitor for years.. But this is not acceptable from a security stand point!
    I'll look into the issue you're talking about lacrits--thanks for the heads-up.

    Sub optimal results for DDR3 2x2GB kits. To compensated for the increased tRD and timings over DDR2 counterparts DDR3 kits should achieve DDR3 1333 CAS5, DDR3 1600 CAS6 and DDR 1800 CAS7, numbers that not a single kit in the article was capable, showing that 2x2GB DDR3 kits are much more slower than 2x1GB parts. DDR3 ony makes sense on the 2:1 divider, so we are talking about DDR3 1600-1800 speeds for optimal performance but at this range only a few Motherboards accept tRDs of 6, and most cant even handle tRDs of 7. Until further results i still advocate the use if DDR2 2x2GB kits capable of CAS5 tRD5 operation mostly on the 1150-1250Mhz range, all of them south of the $200 mark...

    this is said like its not happened.... my most recent build on a gigabyte p45 board is running 2gb of ocz platinum ddr3-1333 @ 750mhz like a champ...

    this was built well over a month ago and there were several boards then supporting 1600 fsb and ddr3-2000.

    my ram defaulted out at its stated 7-7-7 timings @ 667mhz stated speeds.

    Yep, I figured as much on my own, cangelini. However DDR3 1333 in my opinion is getting there to the "acceptable" price range, but DDR3-1600 still has a long way to go. I'd like to see soon after Core i7 and the X58 chipset is released an article about the effect of DDR3-1066, DDR3-1333, and DDR3-1600 on overclocking, I believe that's when we'll be able to make an informed decision on which are "mainstream ready & accepted"

    It hasn't--X58 isn't out yet. The response was to emp's question on Nehalem =)

    X58 isn't out yet.
    whats the point of this review than?

    ddr3 hardly offers a solid 1% over ddr2 while the price would suggest otherwise. Same goes for the i7. How fast will it have to be to compare to 3.6ghz core2 quad? at what price?

    face it, ddr3 is useless to us, and only reason any sane person would even be considering it is due to intel making it mandatory for the i7.

    sure it will be nice one day in the future. So, 'till the future comes, in a year or two, stick with ddr2 pc800, you dont need any faster anyways.

    LOL, I know you meant PC2-6400. Because PC800 is DDR...RDRAM.
