Server Board SE7520JR2 Specifications
1
Intel
®
Extended Memory 64 Technology (Intel
®
EM64T) requires a computer system with a processor, chipset, BIOS, OS, device drivers and applications enabled for Intel EM64T. Processor will not operate 
(including 32-bit operation) without an Intel EM64T-enabled BIOS. Performance will vary depending on your hardware and software configurations. Intel EM64T-enabled OS, BIOS, device drivers and 
applications may not be available. Check with your vendor for more information.
