I am really to hear you are having problems with your system but let me help you.
When the memory controller inside the processor is damaged the most common behavior in the system is to get errors/beep codes since the system may not recognize the RAM properly.
From our side, I recommend you running the Intel® Processor Diagnostic Tool. This is a software that test every internal component in the processor and In the case there is something wrong on it, will be displayed.
Here is the download link:
I also recommend you updating the BIOS in your system to the latest provided by ASRock. Here is their support site:
The memory test will diagnose the ram stick connected to the system so if you connect both, the program will test dual channel. There could be a problem with the memory controller when testing dual channel configuration so my best recommendation is to contact the motherboard manufacture for them to test it or replace it if necessary.
At this point all Intel® processors are capable of running memory at 1.5v only. Now, you can try if you want running at 1.65v but we do not recommend that since the processor can be affected or the performance in your system.
From our side i can confirm that the correct speed for a Sandy Bridge is a memory up to 1333MHz running at 1.5v.
Here you can check the processor specifications:
