Mainstream-Ready? DDR3-1600 Shootout

Features

Conclusion

We didn’t see much performance difference between the various DDR3-1600 module sets, regardless of speed or timings—not even when using an enhanced FSB-2000 to the processor. If we assume that benchmarks are only consistent to plus or minus 0.5%, we could simply state that when it comes to DDR3 memory, the cheaper the better. The overclocker in all of us wants the best RAM, but the best overclocking memory of today’s shootout is not yet widely available in the U.S. market. Buffalo FireStix FSI1600D3G-2G will certainly get a lot of attention from buyers once availability improves, regardless of price.

Aeneon XTune AXH860UD20-16H is available, so its second place overclocking-capability would put it at the top of our shopping list if not for the comparatively higher timings required at slower speeds. Another factor benefiting Aeneon’s potential customers is its low voltage requirement, which results in lower power consumption, lower heat, and possibly better longevity.

Kingston HyperX KHX12800D3K2/4G came in third for overclocking, but supporting superior latencies at lower speeds allows it to leap past second-place overclocker Aeneon to make it the most desirable of available parts. Of course its relatively high price will prevent Kingston from winning any value awards, given the proximity of lower-cost competitors.

Who, then, provides the best value ? Enthusiasts on a budget might choose Wintec AMPX 3AXH1600C8WS4GK as the least-expensive of all DDR3-1600 competitors, but OCZ’s Reaper HPC OCZ3RPR16004GK costs only around 12% more. That 12% price increase gets buyers a third-place contender in the ever-so-close latency battle and a set of modules able to handle a 5% overclock that cheaper parts can’t tackle.

    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.
