2. Based on the SPEC apc 3D Studio Max 9 and Cinebench R10 benchmark tests
performed by Dell Labs in January 2009 comparing the Dell Precision T7400 with Intel®
Xeon® X5482 processor and 4GB memory with the Dell Precision T7500 with Intel®
Xeon® W5580 processor and 6GB memory.
3. More than 96GB of memory requires a second processor and Genuine Microsoft®
Windows Vista® 64-bit or Genuine Windows® XP 64-bit and more than 128GB memory
requires a second processor and Red Hat® Enterprise Linux®. A 64-bit operating
system is required to support 4GB or more of system memory. With over 72GB, memory
will only run at up to 800MHz.
4. Significant system memory may be used to support graphics, depending on system
memory size and other factors.
5. Maximum memory with dual processors installed. A 64-bit operating system is required
to support 4GB or more of system memory.
6. A 64-bit operating system is required to support 4GB or more of system memory.
7. GB means 1 billion bytes and TB equals 1 trillion bytes; actual capacity varies with
preloaded material and operating environment and will be less.
8. The T7500 and T5500 use a very efficient Active Power Factor Correction (APFC)
power supply. Dell recommends only Universal Power Supplies (UPS) based on Sine
Wave output for APFC PSUs, not an approximation of a Sine Wave, Square Wave, or
quasi-Square Wave (see UPS Technical Specifications). If you have questions, please
contact the manufacturer to confirm the output type.
