"Hi,
I've similar problem about my Gigabyte GA-MA770-DS3 v.2.0 mobo. I've 4 identical stick of Kingston DDR2 KVR800D2N5/1G RAMs (800Mhz). All works without problem with my Athlon X2 6000+ 3.1Ghz (Dual Channel). Last week I upgraded my CPU to Phenom II 955 BE (Stepping C3). I've already upgraded my BIOS to FDc to support this CPU. With 4 slot RAM board makes long beeps and no boot. 2 sticks with seperated channels boots normally. I cannot change DCT to Unganged to Ganged. It changes but when boot screen says still 800MHz unganged. Gigabyte PDF file support that model of RAM. And only 1066 Mhz ram needs 1 stick per channel. I also sent a service request mail to Gigabyte about the issue but no reply so far.
Is there any advice..? Thanks.
Ps.
+ Cleared CMOS, Hard set RAM Timings, lowering mhz to 667, even increase Voltage +0.1, tried different RAM's KVR800D2N6/1G. "
I have same problem but my motherboard GA-MA770_UD3 2.0
I upgraded my cpu amd athlın x2 6000 to amd phenom ii x6 1090t BE.
I cant use my all ram slots; I can use 2 slots
I have ddr2 800 4x2 gb ram but now 4 gb only
Motherboard bios versin fkd ...
+ Cleared CMOS, Hard set RAM Timings (What is that your ram timing settings ?, lowering mhz to 667, even increase Voltage +0.1, tried different RAM's KVR800D2N6/1G. "
