Overclocking Asus PsN-D w/Q9650

So I can't get my computer to over clock at all and its driving me nuts anyone have any suggestions?
Asus P5N-D motherboard
4 X 2GB Gskill DDR2 PC6400
Yorkfield Q9650 Core 2 quad @3.0 ghz
Rocketfish 550w PS
BFG 9800 GTX+ OC
Samsung 5200 rpm HD
Zalman CNPS 9700 LED CPU cooler

I set Bios settings:
Spread spectrum control : Disabled
CPU internal thermal control : disabled
Limit CPU MaxVal : disabled
Enhanced C1(C1E):Disabled
CPU C state capability: disabled
Execute disable bit:disabled
CPU multiplier:9
Enhanced intel Speed Step: disabled

memory timing and voltage left at automatic
CPU volt : 1.3-1.36
HT V: 1.4
NB V: 1.4
SB V: 1.6
When I try to overclock it even a little it will boot and start loading windows then shortly after windows loads I get a blue screen ****Hardware Falure****** any ideas?

  1. Have you tested your RAM with memtest86+ at boot? Are you using the RAM dividers in the BIOS to keep your RAM speed within its specs. when you increase the FSB to OC the CPU?

    That is a POS. I recommend you swap it out ASAP.

    1. Make sure RAM:FSB is at 1:1

    2. Make sure RAM voltage is correct. (Usually high performance DDR2 RAM need 1.9-2.1v).

    3. Download and run Memtest86+.

    4. What temps at load on stock settings?
  3. Everest temperatures : when idle:

    Motherboard 35 °C (95 °F)
    CPU 43 °C (109 °F)
    CPU #1 / Core #1 37 °C (99 °F)
    CPU #1 / Core #2 34 °C (93 °F)
    CPU #1 / Core #3 37 °C (99 °F)
    CPU #1 / Core #4 37 °C (99 °F)
    GPU Diode 46 °C (115 °F)

    Everest temps @ full load running intel burn test 5th run:
    Motherboard 39 °C (102 °F)
    CPU 69 °C (156 °F)
    CPU #1 / Core #1 58 °C (136 °F)
    CPU #1 / Core #2 56 °C (133 °F)
    CPU #1 / Core #3 58 °C (136 °F)
    CPU #1 / Core #4 56 °C (133 °F)
    GPU Diode 50 °C (122 °F)

    What PS would you recomend shadow?

    I have been leaving the ram at an unlinked setting and using 1.9v.. Bios shows that the ram still maintains 800 mhz while I try to adjust the FSB I haven't adjusted the rams timing manually, I've been leaving it at automatic settings

    I was semi successfull overclocking FSB to 1440mhz,Ram @800mhz, ran intel burn test with temps similar to those above. Finished the test successfully then like 30 seconds later Blue screen.

    I would like to overclock the FSB to 1600 and get the processor to 3.6ghz but I can't even post at 1600mhz but it won't post at 1334 either ( 1 over stock)

    right now I have the ram running at a 2:3 ratio with fsb at 1333 so it seems that the ram will overclock.

    I will run memtest86+ tonight to make sure I don't have a bad module and post the results, thank you for trying to help

    A quality Corsair, PC Power, Antec, OCZ or Seasonic unit. For your set up, a Corsair 450VX/550VX will be fine.

    I have been leaving the ram at an unlinked setting and using 1.9v

    Try linked FSB:RAM at 1:1.

    Your temps seem fine.
