Solved Gigabyte GA-EP45-UD3P Tags: Motherboards DDR2 RAM Gigabyte Last response: February 11, 2013 3:09 PM in Motherboards Share akot783 February 11, 2013 1:42:34 PM Hi, I have the below motherboard Gigabyte GA-EP45-UD3P I currently have 4GB RAM on it. (G.SKILL PI Black 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800) I am looking at upgrade options. DDR3 RAM seems much cheaper. Can I use them in this motherboard? Will DDR3 RAM fit in DDR2? I believe the config of this Motherboard is for DDR2 as per the site. Any suggestions on the memory upgrade options I have for this board? Thanks!

I found G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400CL5D-4GBNT for 45 dollars in Newegg. Is this something that I can use along with my existing 2x2GB RAM? The existing one is G.SKILL PI Black 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) alexoiu a c 554 V Motherboard February 11, 2013 2:20:53 PM Theoretically, they should work. Sometimes, voltage adjustments are needed. However, if using Windows 8 32-bit, the memory limit is 4GB. akot783 February 11, 2013 2:27:25 PM But according to my System Info - I have Windows 8 32-bit, x64 based processor. So I should be able to have 128 GB RAM, correct? This is what I see in the msdn (link below) http://msdn.microsoft.com/en-us/library/windows/desktop...(v=vs.85).aspx#physical_memory_limits_windows_8 Comments? Best solution alexoiu a c 554 V Motherboard February 11, 2013 2:31:30 PM Share No, 32 bit Windows is/are not able to use more than 4GB. Even if the processor is x64 capable. It's a software limitation. akot783 February 11, 2013 3:09:36 PM Thanks for the info. That settles it! Can't find your answer ? Ask !
