Hello folks, newb to the board looking for memory help. I have a gigabyte ds3 m-board running about a year with no issues. In late September, I upgraded the original memory with a-data 2 x 1g 1.8v memory modules in slots 1 & 3. http://www.newegg.com/product/...p?item=N82E16820211066 . About a week ago I purchased the exact same item number from Newewgg, thinking I would get 4g going with 2 (1 x 2g) kits. Unfortunately, after installing the new ram, I got a loud beep followed by an immediate reboot. This was an endless cycle until I powered down. I tried setting the memory manually in bios to 800 and 5-5-5-18 timings as stated on specs. No change. I could not get one stick of new memory to boot up in slot 1, fast beeps followed by auto reboot. Also, had trouble getting original memory up and running. Inserted original memory in slot one and would not reboot. I took a break reinserted the other original memory in slot 1 and I was able to reboot. Now I only have one original stick running in slot 1. What's going on, what do these beeps mean, and how can I get these modules up and running together. Also, even though I purchased the exact same item number from Newegg within 2 months, their part numbers are different. 1st one purchased is labeled HYQVE1A16, and the most recently purchased one is labeled ADQVE1A16. Any help would be appreciated.
