Since the demise of Winbond BH5 memory chips, 2-2-2 memory has essentially been dead at DDR400. Corsair and others have produced DDR400 2-2-3 and 2-3-3 parts based on Winbond CH5 and other memory chips; however, 2-2-2 all but vanished as supplies of Winbond BH5 and BH6 disappeared. Other manufacturers such as OCZ took a different route with innovative products like Extended Bandwidth memory, which is extremely fast, but does not depend on the lowest CAS timings for best performance.

When Corsair 3200XL appeared on the market in June, it was the first time since the death of BH5 that we had seen a memory with 2-2-2 timings at DDR400. More than that, this new memory also proved to reach DDR500 performance levels - something that Winbond BH5 could never do. We certainly took notice of the new memory based on Samsung chips, and it looks like every other memory maker also took notice. Since the Corsair introduction, most major memory manufacturers have announced their own DDR400 2-2-2 memory.

Today, we will compare five new DDR400 2-2-2 memories. There is also a 6th DDR400 2-2-2 memory, from Samsung themselves. However, since we had only received 256MB modules from Samsung, and all other modules were 512MB, the Samsung was not included in the roundup. Including the 256MB Samsung in the roundup would not have been a fair comparison, since we know that 2 single-sided modules do perform slower than 2 double-sided modules on the Intel platform. For more information on the performance of the Samsung memory, please check our review, The Return of 2-2-2: Corsair 3200XL & Samsung PC4000.

As you will see, though, not all the new DDR400 2-2-2 memory performs the same, even though most are based on the same Samsung chips. In fact, not all of the new memory is even based on the Samsung chips, as there is another exciting new DDR400 2-2-2 memory chip now available. The new DDR400 modules all performed at 2-2-2 timings as promised, but beyond that base performance, some memory went further than others in the roundup, exhibiting unusually high bandwidth. Other memories allowed faster timings across the bandwidth, even performing with complete stability at an astounding 2.5-2-2-5 at DDR500.

Which were the standouts, and which were bunched in the pack? Let's take a closer look at the new DDR400 2-2-2 memory to find some answers.

    #26 - DDR460 2-2-2 at 2.75V according to my review notes Reply

    It's said that the crucial did 2-2-2 up till DDR460. At what voltage is that?

    crucial has always been highly overclockable. my regular cas3 ddr400 crucial does cas 2.5 at 250fsb. Reply

    You quoting performance series and not Platinum rev2

    Platinum rev2 uses TCCD and was used for this roundup.

    OCZ would like to to announce a revision change in our PC-3200 Performance Series line of memory. PC-3200 Revision 2 has been discontinued and replaced by OCZ PC-3200 Revision 3 DDR.

    OCZ PC-3200 Revision 3 DDR is specified for CL2-3-3-6 timings o­n Intel-based systems and CL2.5-3-3-6 timings o­n AMD based systems. The lifetime warranty of existing PC-3200 Revision 2 modules will not be invalidated by this change.

    Nice article, nice charts and nice memory. With all the extra work from the new components let's hope you're still having fun, Wesley. Keep the i875 going. I'm not sure about the nf3 if the tRAS has to be set to >10. Any chance OCZ might be releasing a CAS2 DDR500 in the near future with that new batch of Samsung chips?

    #19 - From page 9: "We have seen reports of some variability in the performance of the Ballistix memory, and overclocking results are never guaranteed. However, our results with another pair of Ballistix DIMMs were very similar." Reply

    As long as it is a reputable vender, quantity is often better than quality. :)

    i.e. 256MB of 3500 level 2 mushkin extreme blah blah is probably going to perform worse than 1GB of corsair value ram.

    Wesley you have still yet to comment on the question of whether or not the crucial sticks were cherry picked or not. I know in a lot of reviews you try and get your products as anonymously as possible is this true with the crucial ram or not? If not these could hardly be indicative of ram that the rest of us could get and should be known for people who plan on purchasing ballistix ram. Reply

    Is there a comparison anywhare of "Value" memory against this high end, high $ stuff. For example, I cag get 1G of Coorsair Value for $180 and the lest expensive high end memory is about $280, a $100 difference. How much real performance is this $100 getting me?
