di/dt Step current 2 A 2, 3
Slew Rate Voltage Ramp rate (dV/dT) 0.5 10 mV/uS 1
Notes:
1. Long term reliability cannot be assured in conditions above or below Max/Min functional limits.
2. Step is done in 100nS.
3. di/dt values are for platform testing only. This parameter is not tested on Intel silicon. Testing should go up to and
include IccMax.

Notes:
1. The current supplied to the DIMM modules is not included in this specification.
2. Long term reliability cannot be assured in conditions above or below Max/Min functional limits.
3. Step current between 1 amp through 8.5 amps is done in 150nS
4. di/dt values are for platform testing only. This parameter is not tested on Intel silicon. Testing should go up to and
include IccMax.
