HELP! BIOS over / underclocking?

Hi, i have a problem... I have just completed a new-build with the following;

i5 3470 quad core 6mb - 3.2GHZ / Corsair 2x4GB 1600MHZ DDR3 / SSD 90GB 6GPS / Gigabite GA-Z77-DS3H.

Everything seems to be running OK, But the BIOS indicated speeds are way-way off, it tells me that;

CPU = 3632.77 Mhz (but isnt this the same as running at 3.632 Ghz?)

Memory = 1345 Mhz (but this is in the 1333mhz range, not the 1600mhz i expected)

Does anyone know why my bios readings have WAY overclocked the readout for my CPU and WAY underclocked my memory?

Im worried as it all new to me really, and that the CPU will burn out / and or i wont get the best from my memory chips. I could imagine such readings if i have played around in the settings, but this has just ben a PLUG AND PLAY set up, and this is what i got...

Can anyone shed some light??

Many thanks

Tom

  1. the cpu goes to 3.6ghz with turbo turned on

    manually set the ram to 1600mhz or use xmp profile for 1600mhz if your ram has it

    quite common for bios to set ram at the wrong speed

    Do you have any idea why the CPU is default in Turbo? Not sure how to turn that off...(if it is on).. is setting the ram manually at 1600, and setting it at 1600 with XMP, the same thing??

    : ) thanks!
  3. Its also telling me that the CPU/ PCIe Base Clock is 100.00MHz, giving a reading of 36 X 100.90 MHz, is this something to do with it?

    : )
  4. turbo is on by default--gives an extra boost--wont do any harm--it wont burn out

    bclk is 100mhz--but 100.9 is within tolerences--so yes 36 x 100.9 gives you just over 3.6ghz

    setting manually or by xmp doesnt really matter but by xmp is simpler

    ok, if i reduce the base clock speed, will that bring the overall MHz down? And would it pro-long the life of the CPU in doing so?

    Thanks again : )

    p.s, would formatting an installed windows xp 32 bit, on a SSD for a clean install of windows 7 64bit (i have 8GB ram) impede the performance of the windows 7 after wiping it clean?

    : )
  6. yes if you reduce the base clock speed the mhz will go down

    but so will your ram speed

    wont prolong the cpu life --its running as it was designed to now

    and no formatting wont impede performance and obviously to use all the 8gb ram you need 64bit
Ask a new question
