Life At 2 GT/s: 6 GB DDR3-2000 Memory Kits Compared

Patriot Viper, Super Talent Chrome Series

Patriot Viper DDR3-2000 CAS 8

Patriot’s PVT36G2000LLK name breaks down easily to reveal a three-channel, six-gigabyte, DDR3-2000 Low Latency Kit, though its rated latencies are middle-of-the-road compared to competing parts.

Blue-painted heat spreaders increase surface area by way of ridges and fins to keep these CAS 8 modules cool and stable at 1.65 volts. We're again not sure about the decision to cover the spreaders with paint, but look forward to taking a closer look in the overclocking results.

SPD timings for DDR3-1066 are a little lower than those of most competitors, but DDR3-1333 automatic configuration values are absent. Users of XMP-capable motherboards can take these modules to rated 8-8-8-24 timings by altering a few BIOS settings, though the altered base-clock required to reach DDR3-2000 is probably best done through slightly-lengthier manual configuration.

Super Talent Chrome Series DDR3-2000 CAS 9

Super Talent kept its prices low in spite of limited availability, so the only way we could find its Chrome series WB200UX6G9 modules in stock was as $80 single-stick WB200UB2G9 packs. Several retailers with depleted stock still list the triple-channel kit with prices as low as $220, but we multiplied the single-stick price by three since that’s the only way to buy these today.

Top fins and plated finishes have become so popular among various brands that the only way Super Talent could make its product visually different is by combining those traits. The combination of good looks, high speed, and moderate pricing should appeal to multiple enthusiast segments.

Super Talent includes a DDR3-1333 SPD value plus Intel XMP for DDR3-1800 CAS 8. We believe the next higher XMP value is programmed as XMP-2000 but misread by our combination of non-XMP test motherboard and CPU-Z. Advanced users won’t need XMP to configure the product’s highest-rated DDR3-2000 CAS 9-9-9-28 settings, and getting there requires base clock alteration anyway.

    Can I make a suggestion? I would like to see a trial, in which the i7's integrated memory controller is overvolted incrementally to death.

    Much has been made since the inception of Nehalem about the offical "safe" vDimm limit of 1.65v. There have been no lack of intrepid overclockers who've pushed this spec to 1.7, even 1.75 volts. I want to see the actual limitation demonstrated in spectacular fashion with pictures. Also, I highly suspect memory voltage on the X58 platform is capable of increasing the CPU heat output; it would be satisfying to see confirmation of this. Give this idea some thought.

    Hey guys, THG is the best! People you need free tech support THG is #1! The article is nice, I wish we had a big comparison to really show - 3 cpu's, different rans....well anyways!!! Good info as always, fact is you do get significant ranges of mem bandwidth at the same settings. You can take different types of ram , set them at the same settings all 100% stable and yes huge swings in membandidth.

    Yes, in in many cases high end ram give slight increases, those ranges of 10-15% are common for bandwidth. Yet the i7 system is so advanced and so far a head of software, the software rarely knows the difference or the results i should say.

    WSZ says: Skip 2000 ram, go for 1600 ram, a 920 at 1500-1700 fsb is untouchable for the pricer to performance provided. THG has show muskin 7-7-7 or slightly higher latecy ram to really blow everyone away.

    We live in the best times, for the advancement of computer parts, we an not shirink for ever!!! We are at 32nm? Then what 3 atoms thickness?

    Yes, AMD really has a good system now with the south bridge 750 oc, but nobody cares - i mean my customers. 7-8-7-20 at 1.65v at 1550 to 1650 is the sweet spot if you can squeeze it out - you may just go with 8-8-8-24 with 6GB of $100 ram. Sweet spot on the 20 multipier is 3.8ghz air cooled. We getting 4.4ghz with water - i toss a photo in for fun - this is mid level system with minmual rads but runs 70-75c at 4.3ghz all day with quad sli: http://s329.photobucket.com/albums/l373/warpedsystems/?action=view&current=WSZ-WCcm-T31.jpg

    philologos -- does not help at all, in fact it just makes the system unstable, skip the stroy why we set thte QPI to 1.65v instead of 1.33v as was to be done. The reuslts:
    system was find, after 3 weeks starting have issues - crashes
    bottom line is do not to it - 1.33-1.35v is fine for most QPI

    1600MHz DDR3 still provides the best price/performance. Not just that, but there is about 0.5% real world performance gain from higher clocked memory.

    exactly doomtomb
    in fact this has not change for 3 years

    around 1600-1700 is the sweet spot, in highend and exact system, make just one lateny setting lower - we are build 3 systems. one, is a $4000 air cooled system, one is a $5000 water cooled and one is a $6000+ water - these are not gaming sytems.

    Getting the fsb is right is the most important thing in building a system, while i can it fsb in a i7 - it still the memory bus evern if its not fsb or front side bus

    2-2-2-5 ram for ddr400 ddr
    3-3-4-8 ram in ddr800 ddr2
    7-7-7-20 with ddr3

    Unfortunately that's impossible. They don't die instantly, they die over a matter of weeks. Intel published a bunch of data on how long the memory controller last at various voltage levels, we're talking several weeks at 1.70v and at least a few days at 1.75v.

    So, when the memory controller finally did die, nobody woul know whether the voltage or time was the most significant factor.

    Awesome review Thomas. Thank you for making a great comparison... I still think Kingston's DDR3-2000 is the best value over all. Pushing the CPU past 1.7v core is not an option in my opinion, and anyone with good clocking skills can push a core i7 920+ to 4.0GHz @ 1.25v with this kind of RAM speed and bandwidth. I'm running an (1066 strap)E6600 @ 3.6GHz, 2:8 ratio and 20MB/s dual-channel throughput on DDR2-1200, the 8800GT Superclocked Version and it runs crysis like silk on 2ms 1920x1080p. Super Talent has shown better performance and value in this line and i'm glad to see it as well. This is the kind of performance i have been waiting for and its a great confirmation of what i have been suspecting about these RAM's. The only reason why i haven't changed the graphics is because Nvidia/ATI have not had a significant jump in hardware besides the 4870x2 and GTX295 (too expensive/too much power needed), but i know the good stuff is coming Q4. Time to build another 5yr build with a quad this time ^_^

    Great review. At the pricing chart I was eyeing the Kingston with the low price and decent rated timings. I was surprised to see the cheapest kit, the Super Talent, to match up with the best in timings, that'd definitely be a great buy.

    Ya, check that supertalent review on newegg - oops thats me! we used that in many systems!
    if you want to pot for the extra bandwidth get muskin

    corasir gave us 10%+ more bandwidth at the same settings a supertalent - then again it was double the price

    Nice article..But I thought it'll include real time programs and games benchmarks. Honestly, we all know the difference netween them is so small, that's negligible.
