[Solved] Memory

I have been trying to research this question before asking here but basically needed some confirmation. I just purchased PNY MD4096KD2-800-X4 CAS 4 memory instead of the PNY MD4096KD2-800 CAS 5 due to the fact that they were about the same price and also due to the better CAS latency. On the packaging it says 2.0V. On PNY's web site it says 1.9V. In my BIOS there is no adjustment for the memory voltage. I am not planning on overclocking my memory so it will run fine at the 1.8V right? The higher voltage is only the maximum if you are going to overclock it right?

The memory is already installed and I ran CPUID's CPU-Z before I saw your reply. Under the SPD tab it says Frequency 266 MHz CAS# Latency 3.0 RAS# to CAS# 3 RAS# Precharge 3 tRAS 8 tRC 16 Voltage 1.8 V, Frequency 400 MHz CAS# Latency 4.0 RAS# to CAS# 4 RAS# Precharge 4 tRAS 12 tRC 23 Voltage 1.8 V
Just to verify I am understanding your reply correctly... because I have already installed it and everything seems to be working fine then there is no reason to be concerned about the voltage that is on PNY's packaging and the voltage shown on PNY's website because that is maximum voltage for overclocking correct?

The only way I could figure out how to check the memory voltage was through NVIDIA Control Panel under View System Information. It says Voltage Interface Level: SSTL (1.8V). Thanks for all the information. I have had to learn a lot about memory since I decided I wanted to upgrade my computer's memory. You helped me learn even more. I don't anticipate any issues with this memory now that I understand that those timing tables in CPU-Z represent what is programmed on the memory modules. I already ran Microsoft's program for testing memory on the intensive tests and it did not detect any problems.

The "SPD" page doesn't tell you what speed and timings your memory is actually running at, it tells you what the board is supposed to detect it at. The "memory" tab tells you what it's actually running at.
