Hi
I have a gigabyte mother board GA-MA790GP-UD4H with amd fx 6400+ 3.2 GHz processor, 2gb x 4 ddr2 (800Mhz (as shown on the printed sticker) kingston) memory modules running windows 7 ultimate x64.
Yesterday suddenly my motherboard stopped detecting ram modules in slots 1 2 and 3, only the 4th slot is working perfectly. I tested all my ram modules in the 4th slot one by one. and all got detected as 2 gb modules. but instead of showing as 800 Mhz the rams are getting detected as 200 Mhz and sometimes showing 400 MHz as per CPUZ id,
the moment I put ram modules in any of the first three slots the machine gives 3 long beeps, screen remains black with out anything showing. I have uploaded pics for better understanding of the issue...
