    newly built system:

    Motherboard = Biostar TF720 A2+
    CPU = AMD Athlon 64 X2 5600+ brisbane
    RAM = G-skill DDR2 1000mhz 2GBx2 (PC-8000)

    here are the CPU specs:
    Name Athlon 64 X2 5600+ (dual core)
    Operating Frequency 2.9GHz
    Hyper Transports 2000MHz
    L1 Cache 128KB+128KB
    L2 Cache 2 x 512KB
    Manufacturing Tech 65 nm
    64 bit Support Yes
    Hyper-Transport Support Yes
    Virtualization Technology Support Yes
    Multimedia Instruction MMX, SSE, SSE2, SSE3, 3DNOW! Professional
    Voltage 1.30 V/1.35 V
    Thermal Power 65W



    My first problem is this - I installed one 2gb stick and went to test out some settings. The HIGHEST clock it allows me to put the memory is 400mhz!!! (even though this is 500mhz memory).

    The CPU is set at 200mhz x 14.5 THe multiplier can be lowered but not raised, and the FSB can be changed.

    Right now the current settings are 200mhzx14.5 and cpu-z is showing my memory as 362.5mhz I can't understand why I can't raise above 400mhz in the BIOS. In the manual it says the motherboard supports DDR2 533/667/800 and 1066(by AM2+ cpu). Is this not an AM2+ cpu?

    What is the ideal setting I should put for the multiplier , FSB (HTT), and memory to give the best performance?



    Second issue is that this board has on-board video, but only lets me select 256mb for 'IGPU buffer size" in the BIOS. I guess I can't go to 512?

    Sorry but I am new to AMD's new CPU line-up.

    Thanks!

    I think I now see that my cpu is AM2, not AM2+ and thus the highest memory supported is DDR2-800 (400mhz). Should I lower the multiplier and raise the FSB? I heard odd multipliers (its on 14.5 now) are not good. Is this true?
