Corsair Announces Xtreme Low Latency DDR Modules: 2-2-2-5
Fremont, CA, May 26, 2004: Corsair Memory, Inc., a global leader in ultra-performance DDR memory modules for PC gamers and enthusiasts, today announced a new family of “XL” memory modules that supports 2-2-2-5 latencies at 400MHz, making the XL family the highest performing PC3200 memory in the world. The new XL product family includes the following products:

TwinX1024-3200XLPRO matched pair of 512MB, DDR400, 2-2-2-5, XMS Pro Series modules
TwinX1024-3200XL matched pair of 512MB, DDR400, 2-2-2-5, black XMS modules
TwinX1024-3200XLPT matched pair of 512MB, DDR400, 2-2-2-5, platinum XMS modules

All these parts are available immediately from resellers worldwide, and are also available as individual 512MB XL modules. XMS modules include Corsair’s classic black and platinum aluminum heat spreaders for improved heat dissipation. XMS Pro Series modules were developed exclusively by Corsair’s R&D team to enhance the gaming experience with 18 memory activity LED’s and a cast aluminum Pro Series heatsink for improved thermal performance.

The 2-2-2-5 latencies supported by the XL family are the ultimate in performance for DDR400 memory. These latencies are the fastest offered in the market today. Latency is the time required for requested data to be ready to read from memory, and is measured in clock cycles. The lower the latency values, the faster the performance. By dramatically reducing the latency specifications in the XL family, Corsair has brought memory performance to new levels.

In addition to 2-2-2-5 performance at PC3200, the 3200XL family demonstrates excellent performance at higher clock frequencies. Typical results seen in the Corsair lab were 2.5-3-3-7 at XMS4000 (250 MHz) clock speeds.

Plug-n-Frag ™ Technology
The entire XL family includes Corsair’s trademarked Plug-n-Frag™ technology that provides advanced latency values pre-programmed into the SPD (serial presence detect) chip on each module. For the overclocker, this means that the XL modules will automatically boot up at the extremely aggressive 2-2-2-5 latencies with no additional BIOS tweaking. This technology was first brought to market in Corsair’s LL family in January, 2003, and has become wildly popular among gamers and enthusiasts.

These modules were designed specifically to give plenty of overclocking headroom for performance tweakers. At slightly higher latencies these modules can yield stable operation at speeds up to 500MHz. Corsair designed these modules with the unique ability to function both at 400MHz with extremely low latencies, and at very high clock speeds with looser latencies.

"The new XL family of XMS products supports obscenely low latencies that we thought were simply not possible” said Corsair VP of Product Development, John Beekley. “Our development efforts have really paid off with a product that not only supports the world’s fastest latencies at 400MHz but also provides outstanding overclocking headroom. The XL family will deliver awesome performance in Intel- and AMD-based systems alike.”

All Corsair modules are tested at their rated specifications to ensure performance. TwinX kits are tested as a matched pair and packaged together immediately after passing test, guaranteeing that the customer receives a product that has been verified in the dual channel environment.

Further information and specifications on this product and other XMS products can be found at Corsair's web site ( These modules can be purchased through Corsair’s authorized sales channels listed at

and they are available.
just received word from tones, I will have mine tomorrow.
(gaming holiday is ON! :)

Are they as good as my BH-5?

kristos 25th June 2004 03:34

If these are the same as what's being promoted the past few weeks then no, they are not as good as bh-5.

They use pc4000 spec chips on a low latency tweaked pcb.

Once you start clocking at higer then ddr 400 speeds, you'll find that you quickly have to loosen timings to get there.

Offcourse, loosening the timings will let you gain quite some mhz because of the pc4000 speed chips :)

The Senile Doctor 25th June 2004 07:14

at least they don't need 3.3 v to be able to hold 2 2 2 5 at higher mhz as all my bh5 needs

jmke 25th June 2004 11:40

my BH-5 does 2-2-2-5 with 2.85v up to 225Mhz... up to 230-235 with 3v.

at 3.3v these babies hit 250 at those timings, the XL sticks also run 250.. but at much slower timings

Xploited Titan 25th June 2004 14:56

So, I'm better off with the sticks I have... k, thx for the info...

The Senile Doctor 26th June 2004 06:46

yeah, but finding 2*512 mb of those bh5 proved rather difficult so I ordered a gig of XL, and with a fx53 cpu I can always try out higher multi's and stick it at its highest stable 2-2-2-5 speed
say 225*12 or sth, my guess is the performance difference between this and 245*11 will be minimal at best...

jmke 29th June 2004 12:41

Max OC of the XL at CL2 2-2-5 = 209Mhz...

that's not very impressive.. and the sticks don't benefit from higher voltage according to the OC-Zone website

The Senile Doctor 5th July 2004 02:13

yeah yeah, but an fx53 can be set at 16*200 with cas 2 2 2 5 so that's all I need :)
or maybe 209*15 ;)
