1090t & ASUS Crosshair IV, Overclocking Help.

post #1 of 48

So i've been at it for 3 days now and i have no clue what is stopping me from overclocking.

System Spec:

MOBO: Asus Crosshair IV

CPU: AMD Phenom II x6 1090t

PSU: 850 Thermaltake Blackwidow

CPU Cooler: Thermaltake Frio

Case: HAF 932

HDD: 1 TB Western Digital blue 6gb/s

Even with all this, double checked and everything Volts and what not. My computer starts up perfectly but then after not even 5 mins with Prime 95. It Crashes. Boom, Blue Screen,


However if i put the CPU Ratio to 19.5 just 0.5 below, @ 3.9GHz it works flawlessly.

Am I doing something wrong? is there something wrong with my volts or Ratio?

Feel Free to ask any questions or leave comments that apply to the thread.

Thank you.

try bumping up the voltage of the cpu more; if that doesn't work bump up the fsb for the ram

A bit moar voltage may be needed.
If you get a heatsink that runs cooler at load (or re-optimize your cooling in some other way that results in a temp drop), you may be able to use less voltage, but that's about it.

I tired the the FSB and nothing, Im thinking of upping the voltage to 1.5 not sure and as for my cooler its running @ 48C Load, which i think isnt that much.
post #5 of 48
Baby steps on the voltage! Get it close then move in 1 step increments. Too much voltage is as bad or worse than not enough. 1.5 is too much for 4 Ghz. (Probably)

Not that it matters, but mine does 4.1 Ghz with 1.46 vcore.

Alright will do, also does HT have any effect on the matter? i have it set to Auto. not sure if it changes anything
post #7 of 48
Keep HT as close to 2000 as possible.

Another thing to do may be to post up in the Asus Crosshair MB owners thread (link in sig)

HT may be what is killing you.
Turn LLC to 100% for both as well.
Start with core speed and then work on the rest one at a time.

And my 1055T takes over 1.52 load V for 4Ghz

LLC ? not sure what that is. as for HT what is a recommended Voltage or just leave it in auto and tune it to 2000MHz

LLC is load line calibration.
Auto for the HT voltage and tune it to as close to 2000 as you can.
