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.

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?

#323Suns, 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.

babyelfPlease let us know your Optimum latency, memory speed and Voltage setting. I should receive mine today.

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

#37 and #38I 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?
