Hi, my problem comes while i have adquired a new Motherboard Asrock 990FX Fatal1ty Proffesional Series and 2x4GB G.Skill Memory Modules DDR3 1866mhz.
Well i i have a Phenom II 955 CPU and i installed the Memory Modules in the Mobo but it detects it as DDR3 1333Mhz, well since it was configured in AUTO i decided to update the MOBO Bio. After that i found the the correct profiles for my RAM that appeared in OC settings, but no matter what i choose, i only get 1600Mhz Max speed for my Memory Modules.
Does Phenom Have a real Limitation with DDR3 above 1600Mhz? The limitation comes form Mobo or form CPU? Is There any configuration i should use to solve this problem? What can i do? i talked with the Technical service in order to receive a response but no answer until.
Technically the Phenom II's max RAM speed is 1333MHz, but it is possible to overclock the RAM. I was able to get my Phenom II up to 1600MHz, beyond that is hit or miss.
Personally I would leave it at 1600MHz as you will not notice any performance difference by going past that.
Oh, i supposed that, in fact that´s the maximum speed i can get with them, also i´ve noticed that the G.Skill Memory Modules i bought are mentioned to be compatible with IntelZ68 & P67 &p55 platforms, does that mean this memory modules are not fully compatible with Amd Motherboards?
By the Way will be the Ram be damage if i use under voltage? or either the system? Thanks
You would have to overclock both the NB and the CPU fairly heavily to hit that. I would just sit at 1600MHz and be happy. There really is not perceptible difference between them.
well thanks, what would happen if in near furure i get a new CPU. it will be compatible with those memory modules? Are you sure it´s a CPU problem and not motherboard´s one? I appreciate your help really.
