The full story
Sorry, I did not think this was going to be a complicated question since by manually changing the BIOS voltage to 2.1 I believed I removed the ability for it to auto configure. Here is the whole story.
Motherboard, Gigabyte GA-EP45C-UD3R
Intel Core 2 Duo E8500 Wolfdale 3.16GHz
Memory, OZC Reaper OCZ2RPR11502GK
Video Card, Gigabyte GV-R485OC-1GH
After building the system at the beginning of the year a system error report advised me to download and run windows memory diagnostic. The diagnostic was detecting a large number of failures. By using my two DDR2 modules one at a time I had isolated the problem to any module installed in socket DDR2-3. All other DDR2 sockets test fine with both modules. The memory was purchased based on it’s listing on the MOB QVL document.
After contacting MOB support the BIOS settings were changed for the DRAM voltage to 2.1V per the memory spec instead of the 1.8V that the MOB automatically used. I was still getting memory errors on DDR2-3 so I opted to replace the MOB before I ran out of RMA time. New MOB did the same thing but by using the DDR-2 & 4 sockets there were no more memory errors with MEMTEST.
Over the past couple of weeks I started to get the error message in the attached screenshot. So I have decided to replace the memory modules with Crucial CT2KIT12864AA1067 based on the selection tools at the Crucial web site. They have already arrived thanks to Newegg’s excellent shipping so I will go ahead and lower the DRAM voltage or reset it to auto prior to installation since I do not want to blow the new modules up.
