Hi all,
I just installed a new 4gb Crucial-brand SODIMM in my Lenovo X220 (64bit i5) after confirming compatibility. Is it okay that the two SODIMMs are operating at different voltages? The old one is operating at 1.5v and the new one is running at 1.35v as can be seen in exhibits 1 - 3 below.
My understanding was that despite the fact that the new stick's latency is better (i.e., higher Mhz) than that of the old stick (CL11 vs. CL9), the smart fellow in my computer would correctly adjust by simply choosing to run both sticks at the lower speed. Is it incorrect to apply a similar logic to voltages?
My suspicion is that it's probably fine given the computer booted and the OS is correctly seeing the amount of installed memory (as per exhibit 4 below)...BUT I'm paranoid so I wanted to make sure. Do you see any issues with my current set-up based on the CPU-Z info (included below)?
Thanks!
