    Coming from you(a master overclocker) I feel better about my "predicament". Thanks.

    Results so far:

    Note: My stable setting are set in the BIOS and I am using Asus overclocking tool to OC my system. This allows me to BSOD or Freeze and the like and allow a reboot or power off and on and get back OK.

    Note: I will be using Cinebench (CB) to test system overclock.

    I started by using 1.45v and worked all the way up to 5.0GHz until the first BSOD.

    Reboot/Restart

    Dialed back to 4.9GHz and tested several time and all was OK.

    I then kept reducing the voltage by 0.005v increments, running CB several time until CB produced an error or my system froze or BSOD.

    Got voltage down to 1.380v at 4.9GHz

    Now I started increasing the Cache speed until CB produced an error or my system froze or BSOD.

    Got the Cache up to 43GHz before the BSOD.

    Reboot/Restart

    Increased the voltage to 1.385v and continued 1 step at a time running CB twice until I got the cache speed to 4.7Ghz in which BSOD.

    Reboot/Restart

    Increased the voltage to 1.390v and continued 1 step at a time running CB twice until I got the cache speed to 4.9Ghz in which BSOD.

    Reboot/Restart

    I've got my OC of 4.9GHz with a cache speed of 4.8GHz with a voltage of 1.390 volts.

    Now I tested temps using HW Monitor (HWM) and Realtemp (RT) Temp readout format = [- core 0 - core 1 - core 2 - core 3]

    Run 1 = HWM [69 68 67 71] RT [68 68 68 69]
    Run 2 = HWM [70 69 69 70] RT [70 70 68 70]
    Run 3 = HWM [70 70 68 71] RT [70 70 69 70]
    Run 4 = HWM [70 69 70 73] RT [71 70 70 73]
    Run 5 = HWM [72 70 69 72] RT [71 70 69 70]

    It is look good so far I think....

    Note: best CB score was 1071

    I no decided to post here to seek further advice from you guys and then BSOD

    Next step I am thinking will be dial it down to 4.8 GHz as I don't want to increase the voltage any higher to stabilize

    Thanks for reading this boring post

    UPDATE:

    I decided to try 4.9GHz with 4.8GHz cache @ 1.400 volts and it worked fine.

    Ran CB 5 times in a row and using HWM the max temps are: 73 73 70 75

    Decide to up the cache to 4.9GHz and system froze after CB had ran.

    Score was 1073


    Another Update:

    With CPU@ 4.9GHz and 4.8GHz cache speed @ 1.400 volts I ran Realbench and for the first 2 minutes all was fine (temps were under 75oC).

    BSOD

    Now back here again to ask if i can adjust anything else to obtain stability?

    cheers

    Results for 4.8GHz overclock.

    Started with

    CPU @ 4.8 and Cache @ 4.5 Voltage @ 1.38 volts. Ran CB 5 time in a row. Temps 71 70 70 71 score 1044

    Then increasing Cache:

    CPU @ 4.8 and Cache @ 4.6 Voltage @ 1.38 volts. Ran CB 5 time in a row. Temps 72 71 70 72 score 1045
    CPU @ 4.8 and Cache @ 4.7 Voltage @ 1.38 volts. Ran CB 5 time in a row. Temps 71 71 71 71 score 1048
    CPU @ 4.8 and Cache @ 4.8 Voltage @ 1.38 volts. Ran CB 5 time in a row. Temps 72 71 71 72 score 1048

    Ran Realbench - settings: [15 minutes - 4GB Memory] = PASS - Temps 78 77 75 79

    Not that happy with the temps I started dropping the voltages:

    CPU @ 4.8 and Cache @ 4.8 Voltage @ 1.37 volts. Ran CB 5 time in a row. Temps 71 72 70 72 score 1046
    CPU @ 4.8 and Cache @ 4.8 Voltage @ 1.36 volts. Ran CB 5 time in a row. Temps 70 70 70 70 score 1048

    Then system froze and BSOD

    Restart and started to reduce the cache speeds:

    CPU @ 4.8 and Cache @ 4.7 Voltage @ 1.36 volts. Ran CB 5 time in a row. Temps 70 69 68 70 score 1050
    CPU @ 4.8 and Cache @ 4.6 Voltage @ 1.36 volts. Ran CB 5 time in a row. Temps 70 70 68 70 score N/A
    CPU @ 4.8 and Cache @ 4.5 Voltage @ 1.36 volts. Ran CB 5 time in a row. Temps 70 69 68 69 score 1053 **

    Now to drop the voltages:

    CPU @ 4.8 and Cache @ 4.5 Voltage @ 1.355 volts. Ran CB 5 time in a row. Temps 70 69 68 69 score 1053 **
    CPU @ 4.8 and Cache @ 4.5 Voltage @ 1.350 volts. Ran CB 5 time in a row. Temps 69 68 67 69 score 1053 **

    ** score looked to high so decided to restart Cinebench

    CPU @ 4.8 and Cache @ 4.5 Voltage @ 1.350 volts. Ran CB 5 time in a row. Temps 70 68 66 68 score 1044

    CPU @ 4.8 and Cache @ 4.5 Voltage @ 1.345 volts. Ran CB 5 time in a row. Temps 68 67 67 70 score 1045 (one run 1051)

    Ran Realbench - settings: [15 minutes - 4GB Memory] = PASS - Temps 73 73 72 75

    Temps are better but would like them lower so I will try reducing the voltages a little more.

    Again while typing this BSOD (love the auto save and restore on this forum)

    I would leave the cache alone, it doesn't help much and is probably the culprit for your BSOD

    I believe your correct @Dude

    will leave the cache alone

    Got it, acceptable voltage and temps

    as @Dude sugested that the BSOD could be caused by the cache speed I set it back to Auto (4.1GHz)

    Using Cinebench again with the following:

    CPU @ 4.8 and Cache @ 4.1 Voltage @ 1.340 volts. Ran CB 5 time in a row. Temps 68 68 66 70 score 1039

    CPU @ 4.8 and Cache @ 4.1 Voltage @ 1.335 volts. Ran CB 5 time in a row. Temps 67 67 67 68 score 1036

    CPU @ 4.8 and Cache @ 4.1 Voltage @ 1.330 volts. Ran CB 5 time in a row. Temps 66 67 65 67 score 1035 - 1037

    CPU @ 4.8 and Cache @ 4.1 Voltage @ 1.330 volts. Tested with IBT (std) 10 passes = PASS temps 72 73 73 73

    CPU @ 4.8 and Cache @ 4.1 Voltage @ 1.325 volts. Tested with IBT (std) 10 passes = ERROR

    CPU @ 4.8 and Cache @ 4.1 Voltage @ 1.325 volts. Ran CB 5 time in a row. Temps 66 66 66 66 score 1039

    CPU @ 4.8 and Cache @ 4.1 Voltage @ 1.320 volts. Ran CB ERROR on 3rd run

    Time to drop the OC to 4.7 GHz

    CPU @ 4.7 and Cache @ 4.1 Voltage @ 1.320 volts. Ran CB 5 time in a row. Temps 65 64 63 66 score 1019

    CPU @ 4.7 and Cache @ 4.1 Voltage @ 1.300 volts. Ran CB 5 time in a row. Temps 63 63 62 64 score 1019 - 1021

    CPU @ 4.7 and Cache @ 4.1 Voltage @ 1.300 volts. Tested with IBT (std) 10 passes = PASS temps 68 68 69 68

    CPU @ 4.7 and Cache @ 4.1 Voltage @ 1.300 volts. Tested with IBT (High) 10 passes = PASS temps 69 70 70 70

    Seems good to me so I dialed these values in to my BIOS

    Tested using AIDA 64 Stability Test for 1 hour 45 minutes with max temps of 63 63 62 65

    I Will now be running my system 24/7 with the following:

    CPU: 4.7 GHz @ 1.300v (cache 4.1 GHz)
    RAM: 3200 MHz @ 1.3530v (timmings: 16 18 18 36 1N)
