Corsair Introduces Revolutionary
Dual-path Heat Xchange (DHX) Memory Technology
Launches New DHX XMS2 DOMINATOR Product Line In Worlds
Fastest DDR2 PC2-8888 CAS-4 Module Pair
(August 28th, 2006) –Corsair® Memory, the
worldwide leader in design and manufacture of high performance memory, today
unveiled the latest innovation in high performance module design, Dual-path Heat
Xchange (DHX™) technology. This performance and reliability enhancing
technology will be available in the latest memory product line from Corsair also
launched today, the DHX XMS2 DOMINATOR™ Series. The advances provided by DHX
enable the world’s first PC2-8888 C4 (1111MHz at CAS Latency 4) speed rating on
a production pair of 1 GByte modules.
The DHX XMS2 DOMINATOR PC2-8888 C4
module will also feature a Corsair DOMINATOR Airflow fan that provides vastly
increased air circulation through the module heat sink. To complement the
launch of the PC2-8888 module Corsair will also offer a lower cost PC2-8500 C5
module for customers who want the added features of DHX without requiring the
additional speed boost provided by the PC2-8888 C4 solution.
Dual-path Heat Xchange (DHX) is the world’s most advanced memory
module thermal dissipation technology. This Patent Pending heat sink technology
substantially increases the memory module’s thermal dissipation so that the heat
generated by the RAM cells can be more efficiently removed from the
module. RAMs that run at lower temperatures enjoy improved performance and
Since traditional heat spreaders are
only attached to the back surface of the memory packages there is no direct
thermal path for the heat coming from the surface of the RAMs to escape
through. The new Dual-Path Heat Xchange (DHX) technology developed by
Corsair engineers uses two paths for the heat to escape from a memory device.
The innovative first path is through the leads of the BGA chips into the
printed circuit board (PCB). When BGA devices are soldered on to a memory
module, an all-metal thermal path is created from the surface of the RAM to the
copper ground plane of the PCB. This thermal path provides very efficient heat
removal. In fact, a study by Micron Semiconductor (application note TN-00-08)
indicated that well over half of the heat generated by a memory module is
removed in this manner.
In order to maximize the performance of this
thermal path, a special PCB was constructed. The height of this PCB was extended
to allow installation of a dedicated heat sink. This heat sink is used to
dissipate the heat generated by the RAMs on the module which has been conducted
into the copper ground plane of the PCB.
The second, more typical thermal
path is through the back of the BGA packages and into high-performance extruded
aluminum heat sinks. Overall, the module has four heat sinks, two connected to
the RAMs and two connected to the PCB. These heat sinks were designed
specifically for the personal computing environment, with fins oriented both in
latitudinal and longitudinal orientation to take advantage of air provided by
CPU fans as well as case fans. The result is a module with superior
thermal characteristics that will run cooler than a module with stamped or mesh
heat spreaders, and thus have greater reliability and over-clocking
The thermal design of the DOMINATOR module is optimized for
the use of impinging airflow. Forced air from directly above the module can be
used to further enhance the performance of the module. Corsair has developed a DOMINATOR
Airflow fan which is designed to be matched with the DOMINATOR heat sinks and
allow even more heat to be removed from the DHX XMS2 DOMINATOR modules. This fan
unit contains three 40mm tachometer-controlled fans to provide impinging airflow
to the memory subsystem. The moderate RPMs required to provide adequate
forced air mean the DOMINATOR Airflow fan is nearly silent.
heat sink assemblies using DHX technology, with the addition of DOMINATOR
Airflow, allows Corsair to guarantee module reliability at over 2.5 volts (2.4
volts, +/- 5%). The combination of this extended voltage and reduced
operating temperature allows Corsair to offer modules guaranteed to perform at
PC2-8888, or 1,111 MHz, at CAS 4 settings.
As with all other new Corsair
XMS modules, the DHX XMS2 DOMINATOR modules are also shipped with Enhanced
Performance Profiles (EPP), the new
open standard for the Serial Presence Detect (SPD) jointly developed by
NVIDIA® and Corsair. EPP simplifies over-clocking for novice
enthusiasts and provides unparalleled control for experts.
XMS2 DOMINATOR Series is a culmination of all the latest performance module
research and design conducted by Corsair” commentedJohn Beekley, VP of Applications at Corsair. “This highly
proprietary module design has the most advanced module thermal dissipation
technology in the industry, providing unparalleled performance and reliability.
The combination of DHX technology with DOMINATOR heat sinks and Airflow unit
results in without question the most advanced memory solution available to
“The DHX XMS2 DOMINATOR Series is a natural
extension to Corsair’s award winning XMS DDR2 product line”, explained
Richard Hashim, Director of Product
Marketing. “Over the past few years, we have focused on developing and
bringing to market cutting edge module technology. Our ability to
manufacture a comprehensive, feature rich range of DDR2 modules that work across
both Intel and AMD platforms is what is expected by the enthusiast
community. We are really excited about the performance and added
reliability our customers are going to see with the DHX XMS2 DOMINATOR
Series. Expect to see products in the market as early as next
The new DHX XMS2 DOMINATOR Series and the DOMINATOR Airflow
accessory will be available at retailers by the first week of September.
Expected retail prices for these modules are from $600-$650 for the
TWIN2X2048-8888C4DF and $380-$400 for the TWIN2X2048-8500C5D. The DOMINATOR
Airflow is expected to retail for under $25.00.
At launch the DHX XMS2
DOMINATOR modules will be offered in two speed grades:
