Hey guys, i know its another thread but i like learning about stuff and you guys seem the most qualified to help me expand my knowledge of OC'ing

Here is my current OC - System spec in sig

CPU - Manual Control

Clock Speed 4004Mhz - 286 x 14.00x

Load Line Calibration - Auto
CPU voltage - 1.4625V
CPU/NB voltage - 1.2500V
CPU VDDA voltage - Auto
DRAM voltage - 1.65625V
HT voltage - 1.40450V
NB voltage - 1.12625V
NB 1.8V voltage - Auto
SB voltage - 1.33825V
S5 1.2V voltage - Auto

CPU Spread Spectrum - Disabled
PCI-E Spread Spectrum - Disabled
Cool & Quiet - Disabled
Turbo-Core - Disabled

CPU Power - 141.60W - CPUID H/W Monitor

I want to try and push up to 4.2Ghz

Anything i should change here?

Using Corsair A50 in an Antec 900 case with good airflow

At 4.00ghz idle = 23C
At 4.00ghz load = 51C (max)

Whats your CPU-NB set to? You'd probably see better gains upping that than going up 200Mhz on CPU (which will probably be harder to achieve with air cooling)

Also - Why disable PCI Spread spectrum?
 
Not directly relevant but:

Not sure about the x6s but for the x2 x3 and x4 phenom IIs you should set Load Line Calibration to 19%. I imagine it will be the same for x6.

That setting should help to keep the vcore steady as the cpu gets loaded. It should have the effect of allowing you to use lower voltages for a stable OC.
 
As zoomee said get your CPU-NB speed up if you haven't already as it will provide a better preformance gain than an extra 200MHz cpu clock. This Anandtech article gives some results as to the performance increases when overclocking the CPU-NB.
 
you already ruining beefy volts trough it so 4.2 would need even more .

my 1090t needs 1.38 in bios, cpuz( 1.4 prime load in windows )

as someone said clock Nb at least to 2.6ghz

Is there any way to set the CPU voltage manually while keeping cool and quiet enabled? soon as I manually set the voltage, it's greyed out on a Crosshair IV Formula. If it's on auto, cool and quiet is enabled. I'm guessing thats the whole part about auto? so it can set it to 1.22 for 800Mhz...

I don't think there is a way.
 
To keep cool & quiet I think you have to use offset voltage rather than typing in a number but not 100% sure as I just type in desired voltage & dont bother with cool & quiet.
 
Thanks guys, have read replies, don't have time to test this now as i going to meet my missus :P

Will give feedback on what i tried later :)
 
What one you have belial8321? I got a 1075T winging its way to me now.

Bargain of the century - CPU, MSI 880GMA motherboard and 4GB DDR3 1600 RAM for £190. Seems to be a serious lack of X6 clocking threads!

Yeah, offset is correct but you still have to enter a number and set the - or + entries. 1.16 - 1.24 at idle, 1.34 - 1.36 load.
