I haven't changed voltages since installing the first sticks, which were 4GB. I installed the same make/model of ram, so now I have 8GB installed.
In Bios it sees the ram. As far as I can tell the ram is showing fine.
The places I looked was System Info, and the Resource Manager.
CPUz - I noticed, the original ram, which I have in slots 1 and 3, shows identical except for the tRC JEDEC #2 column, where it shows 23 instead of 24 for both the old sticks. So....I have the exact same memory/model but they're different?
