Actually from our side, based on the information you provided, the problem seems to be the memory. This is because the memory you are using is not compatible with the processor. The Memory Controller Hub (MCH) of the i7-3770 was designed to support memory at 1.5V only.
Our recommendation is that you please try to test different memory and see if the issue persists. In case that happens, please test one memory stick at the time on every memory slot. Now if nothing works, please contact us using the link below:
I based my choice of RAM on the specifications for the mainboard. I originally had an Intel DH77KC which proved to be faulty, it claims 1.35V support here:
I replaced it with the Asrock board which shows compatibility for this specific RAM here:
Where is the fact that the processor only supports 1.5V listed, and why do both you and Asrock say that 1.35V is supported on these boards which support this processor?
Corsair website says i7 supported:
i7-3770 processor specification DOES NOT say 1.35V unsupported:
Checking the specifications of the memory you are using it has Serial Presence Detect (SPD) of 1.5V which allows the Memory Controller Hub (MCH) manage it with no issues. Besides that, checking the data sheet of the processor family it seems to support that memory even at 1.35V with no issues. The link for the data sheet is the following:
At this point we can recommend you try with a BIOS update to see if the behavior changes, if it doesn’t work please contact us using the link I provided before or call us to our direct line 916-377-7000 option 3.
Yeah I'm a member here as well.

1. Update the BIOS to version 1.50 via Instant Flash -> http://www.asrock.com/feature/InstantFlash/index.asp ; never via OS!
2. DIMM Slots ; CPU: | DDR3_A1 | Empty | DDR3_B1 | Empty |
3. BIOS settings:
- Press F9 ; Load optimal default
- OC Tweaker:
- DRAM Timing Configuration
- Load XMP Setting -> Profile 1
- VCCSA Voltage -> 1.20v ; the XMP should load 1.20v but if it doesn't then manually change to 1.20v
- Press F10 ; Save & Exit = Yes
