Corsair 500W
corsair H50

the problem is ......my e7500 is currently at3.8 ghz..i am however not being able to take it past that!
my vcore..is 1.40 ..even after stepping up the vcore i get errors in OCCT...

note-my board does not have a fsb:ram ratio option..its locked...

my fsb is at 344...cpu multiplier 11
ram is at 860mhz at 2.1v

how can i get it past 4 ghz atleast!! please!

  1. c'mon guys!!
  2. You get errors in OCCT, normally means not a ram problem, well, intel suggests
    VID Voltage Range 0.8500V-V1.3625

    You are already high on the vcore, what are your temps ?
  3. thanks a lot for replying!
    now im stable at 344 FSB...
    2.8ghz! oCCT stable at 8 hours...temps are about 60 on load....doesnt cross 61.

    am i hitting my FSB wall on the mobo?
    i tried a lower multiplier....but still....it does not post...cant be the ram as u said...its only on 860mhz

    NOTE- I DONT HAVE A MEMORY DIVIDER!
  4. You are overclocking your memory. That may be limiting your CPU overclock. You are running DDR2-800 RAM at 860 MHz. Adjust your memory frequency so that the memory is running two times the FSB frequency. At a 344 MHz FSB freq, your memory clock should be 688 MHz.

    Intel's recommended max vcore is 1.3625 volts. Intel's absolute max is 1.45 volts.

    Wolfdale voltage specs:

    And if you still can't push the core speed higher, you may be limited by your motherboard or the CPU chip itself.
