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.

    Hi!

    I'm rather confused when I check my bios for all the abreviations.. TRC, TRAS.... it would be nice to know what to set them all to, I've got the Asus A8V Deluxe board.. and probably ain't the same bios view or settings that msi or others have. I've tried to overclock but the dang thing just hangs and creates not so funny looking bios boot images... Anyway thanx for a nice review. I've made my choice on memory based on it...

    Quite easily, I must say,

    this is the BEST article about memory I have ever read.

    Well done.

    i cant find a crucial ballistix pc3200 @ 2-2-2-5 timings.

    according to their website,

    http://www.crucial.com/ballistix/store/listmodule....

    BL6464Z402 DDR PC3200 • 2-3-2-6 • Non-parity • DDR400 • 2.8V • 64Meg x 64

    they only have a ddr400 ballistix @ 2-3-2-6, is this the ram that AT evaluated?

    3Suns, 2-2-2-5 doesn't mean it takes 5 cycles every 4th fetch. The paramenters are:
    CAS Latency-RAS to CAS Delay-RAS Precharge-Cycle Time (Tras).
    The names actually vary depending on the source. I quote the names used in CPU-Z, as I think they're well establisheed. You should easily find the description of each of these in online references.

    Got my 3200 ballistix.. ran 2.65 at DDR410 at 2-2-2-11 and primed blend for 15 hours
    now running DDR420 at 2-2-2-11 at 2.7V
    i'll try to go more later after i burn in at this speed

    I just ordered my 512MB x2 Crucial ballistix memory for my A64 3500+. I'm hoping to get 2-2-2-10@2.75V for at least 220MHz on Abit AV8 socket 939. I will let you guys know what I have later once I get my hands on those sticks. This will be an acid test for the information that we receive on Anandtech.

    Wasn't so happy with my 2 * 512MB Ballistix either. couldn't get them to run dual channel stable at DDR 400 at 2-2-2-8 on an NF7-S v2.0 using the rated voltage.

    Memtested each of the dimms individually, at 2-2-2-8 @2.8v they max'd at 212 and 205.

    At least crucial have a good RMA service :)

    Has anyone had good experiences?
