Config Details :
Cpu : AMD Phenom II 955 BE ( RB-C3 )
Mobo : Asus M5A97 R2.0 ( NB970 + SB950 ) - no onboard gfx / Gigabyte GA-MA785GMT-US2H - flashed with latest version of bios
PSU : Corsair GS600
VGA Cards : HD6850 / 7300GS
Cooler : Hyper 212 / AMD Stock
Ram : Corsair 2x 4GB Value Select DDr3 1333 Mhz ram - this worked fine as dual channel so there's no chance of incompatibility here.
Problem Description : Running cpu and gpu at stock speed with stock volts - the Gigabyte GA-MA785GMT-US2H gne bad within 1.5 months from start using it - so sent it for RMA and got a repaired mobo with F7 bios. So bought a new Asus M5A97 R2.0 - flashed with latest bios version ( 0906) on the next day of buying. Now on yesterday the M5A97 R2.0 refused to boot - cpu fan everything started but there's no display - so I pressed the mem Ok button - the memory diagnostic red led started falshing and this kept going on like forever - shutdown the pc and tested with a 7300GS gfx card - removed the the cpu remounted it and tested with stock cpu cooler. Still no go.
Tested the cpu on the repaired GA-MA785GMT-US2H and it booted just fine.
Now remounted the cpu on the Asus M5A97 R2.0 - did a blind flash of the bios to the latest version ie 1206 and the falsh was successful acc to the mobo manual and diagnostic Led on the mobo and pen drive. Switched off the machine - turned it on again after 30 seconds - no boot - pressed the Mem ok button on the mobo, the read mem diagnostic led light started flashing and the mobo booted after 4 mins - the deafult bios setting loaded - got into windows OS ( win 7 Sp1 x64 ) - checked the bios version, ram speed, cpu volt, temp using cpu-z and hwinfo - played some games - everything seemed normal -
now the issue is : to start the pc I've to prss the mem ok button everytime and it will take 4-5 min to boot and some time the pc won't even boot and mounting ram modules on black slots makes the pc completely non bootable - if I use ram modules on blue slots the system will sometime boot and sometime not - tested with single and dual ram modules - also used one G-Skill 2GB ram module alone for testing - still the same result .....
