First off, I know that the effective (advertised) frequency of DDR is usually twice the frequency reported by tools like Speccy and CPU-Z. This is not my issue.
The issue is that my reported frequency is 722MHz (measured with aforementioned tools), but I bought RAM advertised as being 1600MHz.
So the reported frequency is actually less than it should be (800MHz).
I bought two sticks of KINGSTON 4 GB DDR3 1600 MHz HyperX Blu RAM, and my motherboard is ASUS M5A97 EVO R2.0.
I glossed over the BIOS, and the only setting that resembled RAM frequency included options that looked rather weird and non-standard, or were even off the 1600MHz mark (some were over 2000).
When originally assembling the PC, the ASUS mobo reported RAM errors and failed POST (presumably). It kept a red LED on, near the modules. I switched them around a bit, tried with a single module, and it didn't work either. Then I took a pause, and when I returned, I put only one of the modules in the mobo again, and it worked - the mobo passed POST. Then I put the second module in. Later when assembling internally, I noticed that the second module was not properly put in place, so I corrected it, expecting problems to arise again. Strangely - they didn't, and now I have 8GB of underclocked RAM.
What is the source of this problem? How can I fix it? (What are your RAM frequencies, just so I can compare?)
