Laptop Memory Undervolt?

Mar 21, 2019
hi, so my gf has an hp laptop with ddr3l memory slots and she wanted me to add ram to it. silly me at the time decided I would just throw in ddr3 like it didn’t matter and now she has random shutdowns. i figure, its probably because of voltage so could I just undervolt the ddr3 to 1.35 volts?
