Overclocking my computer

[Werne]

The problem is, I don't have voltage control. The only thing I can do is take a look at the voltages in BIOS's Hardware Monitor (in there I can see that VCORE voltage is 1.344) and there's an option in Advanced/JumperFree Configuration that says something in the line of CPU Voltage but only two options are 1.2V and 1.35V.

 

EDIT: Also, I've set FSB to 266 (CPU speed 2.94 GHz) but the comp crashed as soon as I started Prime95 torture test. So I decided to set it to somewhere in between (FSB 250, CPU speed 2.75 GHz). I've ran the torture test for 15 minutes on FSB 250 and it worked like a charm with an even lower temperature than the last time, 68^oC.

probably a bit late now but did you check the mobo's manufacturer's site for bios profiles ? its a far safer way to o/c a machine i know asus have a list of stable profiles obviously for asus mobos ,no more risk invovled than flashing the rom file .

Far as I know, the safer way to overclock a machine is to change the settings manually, not to reflash the bios. There shouldn't even be "pre-overclocked" BIOS available, I'd be surprised if there are. The profiles you mention must be referring to something else.

 

Werne: If it's still 1.8V, it's too high a voltage. It can cause CPU degradation.

Try changing the BIOS setting to 1.2V and see if it still boots and what voltage does CPU-Z report then.

i was half wrong you was half right FMOD http://rog.asus.com/14632011/crosshair-iv-motherboards/crosshair-iv-formula-easy-oc-bios-profiles/

take a peak its why i love asus mobo's

[FMod]

Not quite. First, that's just a blog post. These are by no means official.

I mean, they come from an editor, probably an Asus employee, but that's still unofficial, just goes to show Asus' support for its enthusiast community.

 

Second, they are no different from tweaking the settings yourself. No flashing involved. If anything, manual tweaking one step at a time is safer. And you should only try these profiles if you have the exact specified configuration.

 

Finally, mostly only some newer and relatively expensive motherboards can load settings from USB, Werne's baseline board can't.

In my (limited) experience with overclocking a CPU back in the day, either it was the 775 processor or the P5kpl motherboard (tried with both the AM and the C/CM) but something was making it damn hard to get any overclock at all, let alone a stable one.

The tiniest adjustments would bluescreen the whole system :\

That was on a Core2Quad Q6600.

 

Glad im off 775 now. That socket will always remind me of the Celeron.

Hmm, the setting I said was something about CPU voltage is VTT_CPU Over Voltage which I don't get what it means. I tried setting it to 1.2 and 1.35 but it makes no difference, CPU-Z and all other programs capable of showing voltages show Core voltage of 1.824V while BIOS says it's 1.344V when set to 1.35 and 1.21 when set to 1.2. Other than VTT_CPU Over Voltage, there's nothing else indicating that it can change CPU's voltage. I don't get it.

( sorry to keep butting in here werne )

to the best of my knowledge M3 M4 & M5 series allow for bios flashing from the root of a usb device or floopy as well as baseline manipulation of hardware from within the windows os via asus utilities as far as i can tell said manipulation is not much different from either bios controlled HIDs or os controlled HIDs in the way that controll of the what is essentially the primative black screen computer is possible via the bios ,or do i have it all wrong ?

 

sort werne out first then get back to me if you feel like it or even understood my ramblings not sure i did !

 

im gonna watch this thread its getting interesting

These profiles are not for flashing. They are just settings you can set up, save and load.

Werne's BIOS almost certainly doesn't have that function, but even if it did, people don't usually bother creating profiles for low-cost boards.

Yes, some settings can be changed on the fly from the OS. Some can't.

 

You don't necessarily need Asus utilities, there's a number of programs that can do that, most (in)famously SetFSB.

BIOS is the traditional way to do it and it's more reliable in general.

argh crap johhny five time "need more input" right thanks for that much clearer now off i toddle i will leave you in peace .
