WARNING
Altering clock frequency and/or voltage may (i) reduce system stability and useful life
of the system 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.
WARNING
Altering PC memory frequency and/or voltage may (i) reduce system stability and
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 assumes
no responsibility that the memory included, if used with altered clock frequencies
and/or voltages, will be fit for any particular purpose. Check with the memory
manufacturer for warranty and additional details.
