    Does CPU speed affect memory stability (A64)

    I use a 3400 CH CG 1mb with a DFI 250gb LanParty (754 single channel)
    with 2x512mb HyperX PC3200 BH-5

    When OCing at 250HTTx10, (2500mhz) memory is not memtest stable @ 1:1 2-2-2-5 (DDR500) no matter how much voltage i give (not even 3.45V)
    But when i OC at 250HTTx9 (2250mhz) memory at 1:1, memory passes memtest fine at 3.2V (DDR500)

    both are CPC 1T

    Does CPU speed affect memory stability, especially when the memory controller is on the AMD64 die?

    DFI-street forums tells me that its due to memory not being able to keep up when CPU @2500mhz.....anyone can verify this?
    on the otherhand i can run 11x230HTT 1:1 1T (DDR460) and memory is fine when CPU at 2530mhz.....

    anyone seen this behavior before?

    CPU stability affects system stability. If the system is unstable anything and everything can malfunction in any fashion it chooses, or quit working entirely.
