So i purchased the computer above in January when i was originally running Windows XP Professional. With a Windows XP 32bit system you cant really use more then 4gigs of ram so what i had was fine. I started using Windows 7 ultimate in May which i used for a couple week, until i noticed that i only had a spare of 500mb or ram. I play video games and with that limited amount of RAM, programs do not run smoothly. I decided to upgrade to 8 gigs of ram which is a good amount to have with a 64 bit system. I went to newegg and purchased the same ram as before. i received the ram and install it right way. I didn't work. I was confused and started to troubleshoot to see if the ram was bad.
I push each ram in DIMM 1 to see if they were bad. the computer booted up fine. i then started to put the new ram and old ram together in DIMM 1 and DIMM 2. This also worked. i tried adding 3 of the sticks of ram in DIMM 1, 2 and 3. It didnt boot. i have not tried putting ram into DIMM 1 and DIMM 3 yet. I know that DIMM 3 could be bad but they have never been used or anything inserted into them until now.
Any suggestion or comment would be great. I have 30 days to return my new RAM. Just want to point out again i REORDERED the same ram i bought in January. So voltage, timing, everything is the same
Have you contacted G'Skill? When I had this problem I emailed them with my mobo make/model and the memory model# and they were able to give me all the correct bios settings to use until gigabyte came out with new firmware to fix the issue.
