Intel Desktop Board DX79SI Technical Product Specification
18
CAUTION
1.5 V is the recommended and default setting for DDR3 memory voltage. The other
memory voltage settings in the BIOS Setup program are provided for performance
tuning purposes only. Altering the memory voltage may (i) reduce system stability
and the useful life of the system, memory, and processor; (ii) cause the processor
and other system components to fail; (iii) cause reductions in system performance;
(iv) cause additional heat or other damage; and (v) affect system data integrity.
Intel has not tested and does not warranty the operation of the processor beyond its
specifications. For information on the processor warranty, refer to
http://www.intel.com/support/processors/sb/CS-
020033.htm?wapkw=(processor+warranty).
Intel assumes no responsibility that the memory installed on the desktop board, if
used with altered clock frequencies and/or voltages, will be fit for any particular
purpose. Check with the memory manufacturer for warranty terms and additional
details.
