hertzz Posted September 12, 2008 Share Posted September 12, 2008 I recently purchased new parts to put together a system. Everything works perfectly except for the fact that I am unable to boot up my system if I have RAM modules in slots 3/4 on my GA-EP45-DS3R. (There is a continuous reboot loop and no POST beep at all). I am able to run RAM modules separately and together in slots 1/2, but I cannot run any RAM in slots 3/4 whether it be separately or both DIMMs being occupied. This causes a very annoying problem because it means I cannot run my memories in dual channel. Help would be great!! Thanks Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted September 12, 2008 Corsair Employees Share Posted September 12, 2008 I would suggest talking to the MB maker about getting the MB replaced and or tested. Link to comment Share on other sites More sharing options...
hertzz Posted September 13, 2008 Author Share Posted September 13, 2008 I got the motherboard tested and was shown DIMM's 3/4 working perfectly. Could it be stuff to do with voltages etc..? I can perfectly start the system with modules in DIMM 1&2 but no POST in 3&4. Do I need to edit the FSB or any other settings etc..?

hertzz Posted September 13, 2008 Author Share Posted September 13, 2008 Can I ask what settings I need to properly operate my RAM. I had the motherboard tested, and according to the people that checked it, all I needed to do was make sure the settings were right for voltages etc...and the RAM would work properly. They also said to update to the latest BIOS version which I had already done. I have the CM2X1024-8500C5D (1066mhZ/5-5-5-15/2.10V ver4.1). I have already tried some other RAM, and that wont allow the system to POST in DIMM 3 or 4 either :eek: Thanks! Link to comment Share on other sites More sharing options...
hertzz Posted September 14, 2008 Author Share Posted September 14, 2008 Never mind. The problem was that my motherboard's 3rd and 4th DIMM slots were being shorted by the case and motherboard touching. Thanks Link to comment Share on other sites More sharing options...
