Decided to try and overclock my new system (specs in sig) today and copied someone elses settings from the ASUS forum for the same cpu and motherboard, just wanted to check with people as to how it looks, and if i missed anything, as i didn't copy all his settings as it looks like he upped the volts on EVERYTHING, which i'm not happy with... :rolleyes:

These are the settings i used:

CPU Ratio: 8
FSB Strap to Northbridge: 400
FSB Freq: 400
PCIE Freq: 100
DRAM Freq: DDR-3 1600MHz

Load-Line Calibration: Performance
CPU Spread Spectrum: Disabled
PCIE Spread Spectrum: Disabled

I left all the voltages on AUTO (is this ok) except the CPU voltage which i set to 1.22v (CPU-Z reports 1.200v), the reason being, that if i leave it to AUTO and overclock, CPU-Z reports the cpu voltage has upped from STOCK volts of 1.200v to 1.288v... :eek: Do the other volts increase with the overclock if left on AUTO, and if so, what should i set them to... I like to run an overclock with the least amount of increase to voltages... :)

Ok, heres a screenshot of my progress so far:

Also, how do the temps look under load? Thx for any help... :)
 
Yes auto does raise the volts, and usually by more than is needed.


Which CPU cooler are you using?

Using the Arctic Freezer 7 i think its called...

Any idea what volts i should set to manual, and what sort of volts i should put through them... He had the following recommended volts:

CPU PPL Volts: 1.50v
FSB Termination: 1.26v
Northbridge: 1.35v

Any help appreciated...
 
3.2ghz shouldn't need the chipset voltages raised above their lowest setting tbh.

I would also disable loadline calibration and set the CPU voltage to 1.275v.
 
Load line is disabled and CPU voltage is manually set to stock @ 1.200v...

Just need to know what the stock volts are for the following:

CPU PPL Volts
FSB Termination
Northbridge

As they are still on AUTO and you said that they will increase if not set manually when overclocking...
 
If they're on Auto then just hitting the + key once should set them to their lowest/stock value.
 
ok, thx for that will give it a try, and when i'm happy its stable @ 3.2 will push higher, just wanted a safe/stable base to work from... :)
 
Whatever you do, try to keep PLL below 1.6v and FSB Term below 1.4v if at all possible.
 
Ok, back from the BIOS and used your tip, set to AUTO and pressed + to set to minimum, voltages are now as follows:

CPU PPL Volts: 1.50v
FSB Termination: 1.10v
Northbridge: 1.25v

I guess thats their lowest settings, and CPU volts are set to stock aswell... So re-primeing at these volts, if it passes, then i'll try for a higher clock, looks good if this passes are all volts are low atm... :D
 
Yip that looks like the lowest settings.

400x8 should present no problems for the motherboard on stock chipset voltages. Whether your chip can do 3.2ghz on stock voltage is debatable, but certainly worth trying.
 
Well at stock volts prime failed after 1hr @ 3.2ghz, so upped the core volts a small amout and running prime again... ho hum... :rolleyes:
