The TCCD specification was tailor-made for Corsair by Samsung. As a part of
the agreement, Samsung has agreed to directly supply Corsair’s TCCD requirements
until the end of 2005 and beyond. Contrary to rumours that indicate universal
unavailability of TCCD, Corsair continues to provide high performance XMS memory
modules made with 100% Samsung original TCCD IC’s. There has been suggestions on
TCC5 being an equal replacement of TCCD. While the ICs share similar names, they
do not share identical performance characteristics. TCC5 is a down-bin of TCCD
and does not deliver the same performance promise that TCCD does. Below is a
list of TCCD based Corsair products that are currently shipping:

XMS 3200XL 400 MHz / PC3200 2-2-2-5
4400C25 550 MHz / PC4400 2.5-4-4-8
XMS PRO 3200XL PRO 400 MHz / PC3200 2-2-2-5
XMS XPERT 3200XL XPERT 400 MHz / PC3200 2-2-2-5

There has been suggestions on TCC5 being an equal replacement of TCCD. While the
ICs share similar names, they do not share identical performance
characteristics. TCC5 is a down-bin of TCCD and does not deliver the same
performance promise that TCCD does. Based on our stringent testing requirements,
only TCCD can meet the demand. Corsair also uses TCC5 IC’s but because they are
of lesser capability, TCC5 IC’s are used only in the lower grade parts. Below is
a list of TCCD based Corsair products that are currently shipping:

XMS 3200XL 400 MHz / PC3200 2-2-2-5
