Corsair 3200XL PRO
Corsair introduced 3200 Xtreme Low Latency modules in both their regular Black or Platinum heatspreaders and as the PRO version with activity LEDs on top of the module. All 3200XL modules are double-sided 512MB DIMMs sold as a matched pair and rated at DDR3200 2-2-2-5. Corsair claims a very wide range of available overclocks to about DDR500 with typical DDR500 timings of 2.5-3-3-7. We first looked at Corsair 3200XL in the launch review.Test DIMMs were a matched pair of 3200XL PRO with the activity LEDs.

We first saw the LEDs in our review of Corsair XMS4000 PRO. Corsair uses the PRO designation to indicate LED activity lights on the memory, but otherwise, the 3 3200XL memories appear to be the same capacity and they all appear to be using the same Samsung memory chips.
While the Samsung chips used in the new 3200XL are actually rated at DDR500, Corsair has chosen to highlight their outstanding 2-2-2 performance capabilities at DDR400. The SPD is also optimized for fast DDR400 performance.
Corsair 3200XL Specifications
| Corsair 3200XL Memory Specifications | |
| Number of DIMMs & Banks | 2 DS |
| DIMM Size Total Memory |
512 MB 1 GB |
| Rated Timings | 2-2-2 at DDR400 |
| SPD (Auto) Timings | 2.5-2-2-5 |
| Rated Voltage | 2.75V |
The only specification that might prevent using 2-2-2 in all systems is the specified 2.75V rated voltage at DDR400. Most high-end motherboards can provide this voltage, but some mainstream motherboards do not have adjustable voltage, and default memory voltage is 2.5V on many boards. You should check your specifications to make sure that you can support the voltage needs of the new 3200XL modules.

#12 and #13 - Both Crucial Ballistix PC3200 and OCZ PC3200 Platinum Rev. 2 are available in the market. Crucial is a direct marketer as you have discovered.#14 - In your situation I would shop for price for DDR400 2-2-2. The XP boards respond best to Latency as low as you can feed them, but you are not likley to reach OC levels that will be a concern with any decent DDR400 2-2-2 memory. None of the DDR500 will have latencies like 2-2-2 at DDR400.
#15 - There is just one DDR400 Crucial Ballistix (PC3200) - but it is available as 256MB Single-Sided or 512MB Double-Sided dimms as mentioned in the review.

Wesley comments the OCZ was the best from the TCCD modules tested with incredible headroom, so much so it was decided top homours would be shared.Also going by comments already seen here many feel the Crucial modules were very cherry picked.
I know on many forums the 3200 and 4000 is not doing quite so well as the samples seen here.
I do trust Wesleys's testing though, if his modules hit these speeds, they did hit it...
Its always best to get good reviews like this one and then go search for results on forums.

#11 - Thanks had not thought to go directt from Crucial. That is such a good price compared to the alternatives I am worried if is right stuff but description matches. Wesley did not give a part number. Crucial list part number BL6464Z402.bupkus - Thursday, August 5, 2004 - link
I have a 2500+ Barton on an epox 8RDA+ so I'm happy with a fsb frequency of 200. Is my best option to target some PC3200 with low timings or should I think about some hyperX PC4000 on sale?drewintheav - Thursday, August 5, 2004 - link
Is it possible that you were sent a version of the Crucial Ballistix memory that is not indicative of what someone can really buy? Also, it seems like you said that Crucial Ballistix pc3200 was the best overall so why does OSZ PC3200 Platinum Rev. 2 also get a gold editors choice?Potem - Thursday, August 5, 2004 - link
The question is what is the availablity of either of the Gold Editors Choice recommendations? The MSI K8N Neo2 was recommended over a month ago and is still not available in the US (though is fianlly expected to change any day or hour now). I have searched indivdual stores and done both price watch and PriceGrabber searches for both OCZ PC3200 Platinum Rev. 2 and Crucial Ballistix 3200 and have come up empty. In the case of OCZ 3700EB it does sell but the stores often sell out and OCZ having troubles keeping up with demand.rjm55 - Thursday, August 5, 2004 - link
I was all set to buy the Corsair 3200XL and bitching about the high price when I saw this roundup. Thanks for making my life easier. The Crucial is $267 for 2x512MB direct from Crucial and the Corsair is $361 for the same thing at New Egg. Thanks for helping me save a cool $100.Is there any way to tell if the OCZ is the latest Rev. 2 stuff? I noticed the package in the picture is new. Do you look for the new package to be sure you're getting the latest stuff?

Another GREAT review from the FINKSTER....;-)Commenting on G die micron, yield is VERY up and down so i do feel they were choice cut's, EB does pretty much the same speeds with 95%+ of all customers ram running well above rated timings and speed anyway.You guys with the 4000 balistix should have looked at the 3500 and 3700EB ;-)
Thanks again Wes.

Wesley, it sounds like you need to ask MSI for a new bios to get their board more compatible with these new samsung chips? Maybe all manufacturers will need to release a bios update to take full advantage of these new samsung chips?Just a thought.

#5 - We used the same benchmarks in our DDR2 roundup and tested the DDR2 to DDR2-686. That should give you a better idea of comparative performance between DDR and DDR2. We also compared DDR and DDR2 performance in that review, and fast DDR400 performs about like DDR2-533. Just dlick the 'Memory' tab at the top of the page and you will find the DDR2 roundup.#7 - It will be a few weeks, but we DO have some OCZ DDR2 EB modules with better timings that will be included in an upcoming DDR2-667 roundup. Many of the DDR2 modules in last month's roundup ran fine at 3-3-3 timings - much better than the rated timings.
