Dual Channel Memory Shootout

MDT48 writes "Ever wondered if that expensive low latency memory was worth the cash? These guys have rounded up almost every memory module out there and hammered them. Must have taken them ages, and takes almost as long to read, well worth the effort though."

      Super! But note that the article is old, or at least a bit behind the times (it takes time to compile, plot, and publish all that data!) Newer, faster RAM is already available and can allow even tighter RAM timing (2-2-2-2 anyone?) and more overclocking (my DDR500 runs stably at 325MHz FSB.)

      For example, you can get PC4000 (DDR500) @ $259/GB, PC4200 (DDR533) @ $283/GB, PC4400 (DDR550) @ $314/GB, PC2-4300 (DDR2-533, if you happen to have a DDR2 mobo, the others above will all waor in any DDR mobo) are all available cheaper/MB than the high-performers reviewed.

      What'd you pay for that "fastest PC3200 memory on the planet" and let me know how fast you can push it (and be stable) once you get it?

    Well since it is a 33 page read, how about the link to the end where the conclusions are.
    Conclusion
    The Winner

    and for those too lazy to click
    Conclusion
    So there we have it, 18 different types of memory benchmarked to within an inch of their life and to prove what? Well, one thing we've proved is that while even value memory may offer sustained levels of high speed operation, when you want to make it to the scary end of the spectrum above 250MHz you generally need to pay the price premium associated with "enthusiast" modules. Cheaper stuff may get you close, but at the very high-end we're afraid you really do get what you pay for.

    If you're happy to settle for fast rather than fastest, it seems that reputations and price tags count for little in this game. Good chips on a poorly designed PCB and poor chips on a great PCB will both leave you wanting. And even if you have the best and fastest memory on the planet you still need a motherboard that can do it justice.

    Evaluating performance at more reasonable frequencies is slightly easier, but also slightly fuzzier. Some of the benchmark results varied so widely that it was hard to understand what was really going on, and with various tests favouring different attributes and the surprisingly similar stock performance from many of the modules on test, it was almost an exercise in identifying the "Top Dogs", the "Turkeys" and "The Rest".

    We hope you enjoyed this roundup and gleaned at least some information from the effort that went into it. As we hope you've seen, or will see when you glance through the benchmark results, memory is a very complex subject and pinning it down in performance terms isn't as simple as you might imagine. We won't let that stop us trying though.

    Finally we'll pick out some winners. Remember that for our purposes, overclocking is more a pleasant bonus than an essential feature, and though we have made allowance for overclocking performance it hasn't been given the same weight that it might have been given were we writing this roundup purely for enthusiasts.

    Finally, benchmarks do a great job of highlighting strengths and weaknesses in products but it's important to keep things in perspective. Most of us would not notice any tangible performance differences between even the fastest and slowest modules on test here when run at the processor's default speed unless we were specifically looking for them. That's not to say that faster isn't better, it's just not as critical as some would have us believe.

    The Winners
    Value Editor's Choice - TwinMOS PC4000 CL2.5

    Concerns over availability make us a little nervous about handing the value crown to TwinMOS, but we can't argue with the numbers and this is quite simply the fastest memory for the money that we had the pleasure of testing. We only hope the poor availability isn't due to production constraints and look forward to seeing more retailers pick up on what appears to be a very nice product.

    Value Recommended - Buffalo PC3200 CL3

    We may have had little experience with Buffalo before this roundup but both of the Buffalo modules we were sent acquitted themselves well in testing. For the most part, performance levels in the value group contenders were quite evenly matched but Buffalo did enough to scrape onto our leader board. A very impressive all-round showing earns Buffalo a well-deserved Recommended award.

    High-End Editor's Choice - Corsair TwinX1024-3200XL Pro

    Perhaps the toughest choice of all, we eventually opted for Corsair's 3200XL Pro for its shear arrogance. While far from cheap, it consistently set the standards for stock performance while flashing a knowing LED at the competition as it did so. For a change we see a product with a bite every bit as bad as its bark.

  11. Great tests, but lacking the new goodness by randyest · · Score: 4, Interesting

    PC4000 (DDR500) RAM and faster) is here, and it's a lot faster than anything they reviewed. Even if your CPU/Mobo don't support more than DDR200 or DDR333, you can get lower latency (i.e., 2-2-2-2 BIOS timing options will be usable at lower frequencies) and be ready for upgrades using faster RAM.

    I just picked up two 512MB sticks of this amazing stuff to go with my AMD64 3200+ from, of all places, Circuit City (because it is only $129 each, cheaper even than newegg, which is usually a great deal for RAM and has amazing reseller ratings.) Though I just noticed there's a new $40 rebate on newegg's $299 price (for 1GB), making the net $259, or about the same as I paid at CC. Then again, I hate rebates.)

    No shipping and insta-pick up at Circuit Shitty (though newegg is usally free for fedex saver), even with MA 5% sales tax it's a steal.

    Sorry, I digress -- I'm full of gin, tonic, and Italian food. Back OT -- they got their best RAM up to 275MHz FSB (DDR550). The Kingston I got works stable up to 325MHZ (DDR650!!) and it's not much more (a few cents/MB) than the reviewed RAM.

    Just thought I'd share all I recently discovered before someone runs out and buys the best of this review. I think it took so long to write all that review text and compile/plot the data that they missed the new goodies!

    Anybody who's looked into overclocking a CPU knows that two chips are NOT necessarily the same just because they have the same model number. In fact no two are quite the same, even if they came from the very same wafer.

    So now that they tested all these brands and models, how consistent are the results? If I go to newegg and get the one that worked best for them, will the one I get work equally well? On a different board? With a different chipset?

  16. Re:RAM Speed Differences by randyest · · Score: 4, Informative

    Why do people make wrong claims in such a matter-of-fact manner? Is it ignorance or malice?

    Whatever, more modules in general leads to slower access time. More sticks (modules) of RAM adds to the capacitance driven by the memory controller, and therefore increases the propagation delay on those traces. The more connected modules the longer total trace length driven by each IO buffer of the memeory controller. The difference is probably negligible for all but the edgiest overclocker, but there's always a speed advantage for fewer modules.

    I did a quick google and found this example to back me up, but it's not really needed as you clearly have no fucking idea what you're talking about and could not cite one single reputable argument to back up your insane claim. One of your friends spewed that nonsense and you're parroting it because it sounded reasonable. Of course, that's only because you have no fucking idea what you're talking about.

    randyest is NOT replying to the OP question, he's doing so to a -1 modded answer to it that says more modules are faster because some bullshit he pulled out of his ass.

    Of course, there are several things that have failed in this communication channel:
    1. You didn't check who randy was replying to (by clicking the "parent" link at the bottom of his post).
    2. The -1 modded post didn't change the subject line (left it with Re: whatever).
    3. Neither did randy.
    4. /. breaks thread integrity when showing anything with a threshold. Everything under the threshold is lumped under "X more replies".
    5. randy should have quoted who he was answering to. Quoting is good.
