Hello, I recently upgraded my laptop RAM by adding a new module to the free slot. My laptop supports only 1.5v ram.The manufacturer RAM runs at 1.5v (Hyundai Electronics, HMT351S6CFR8C-PB) .

The new Crucial RAM (CT51264BF160BJ.C8F) I got says that it can operate at either 1.35v or 1.5v. CPUID shows that the Crucial RAM is currently running at 1.35v and other at 1.5v, Is this ok? aren't both ram supposed to work at 1.5v? I've also tested ram with memtest86 and dell diagnostics no errors found.

Thanks!

Most software packages look at the DRAMs SPD info which is nothing more than information about the sticks, rather than going into the BIOS to see what they are really doing

Yeah, I also think so. Checked memory tab both ram are running at dual channel same data rate and timing, also checked voltage from other software and results are same which seemed a bit strange to me.
