voltage to high?

eggybob · 7 Jul 2011 at 19:54

Hi i have just done my first ever overclock from 3.4ghz to 4ghz on my new i5 2500k. just a quick worry i have though as the guide i am following seems to have a cpu voltage manual control and in my bios the same area says cpu offset and i have a + mode and a - mode which im not to sure on how to use.. i seem to be stable atm around 50 degrees c but the voltage read as you see below is higher than the guide said to set this to (guide says 1.12v give or take) i have an asus p8p67-m mATX mobo any information on how i may set my cpu voltage manually would be greatly appreciated also is the vore to high for 4ghz and is 50-55 degrees c idle hot for that oc? thanks.

4ghz will be achievable at a much lower voltage

i have a profile saved for 4.2ghz and that only needs 1.232v

thanks whipgeez. but do you know how i can set the vcore manually on the asus p8p67-m mATX boards Bios? thats what i am sruggling with

anyone have an asus or used an asus board that maybe knows how to lower the vcore manually or via this cpu offset option i seem to have instead of cpu manual voltage mode?

or maybe even how to switch if possible from cpu offset mode to cpu manual voltage mode?

Under the bit where you select offset, is there not a manual mode? My P8P67 has that as well as offset.

no directly under cpu offset i have DRAM then VCCIO the PCH then LLC then CPU Spread Spectrum??

is there a way to turn the vcore manual mode on?

Just download the manual and i can't see an option for it.

Just googled "P8P67-M Manual Voltage" first result was this:

The major thing to note about this board is that there is no way to directly set the vcore. Vcore appears to be determined from a combination of your chips native VID, the value and sign of the CPU Offset Voltage, and the Additional Turbo Voltage (ATV) setting under the CPU Power Management Menu

Looks like it can't be done I'm afraid

I have managed to lower it it seems to around 1.28v by putting in a minus offset of 0.100 (im guessing this is mv) that is at 4.2hz and idles at around 50 degrees is that stable or is that to hot really for idling at that speed and voltage?

What CPU cooler are you using, also have you got descent airflow through your case?

50 is a bit high for idle, but more important is load temps. Try running Prime95 to check stability and monitor your temps using Core temp or Real temp.

stock cooler.. i have it at 4.4ghz and 1.288v now runs around 50-60 idle and when running wow,eq2 ect but prime95 it gets upto 90-95 when it gets into the second phase. any suggestions on how i could get the temps down?

Intel Stock Cooler (no way) get a proper air cooler mate!

Justintime · 8 Jul 2011 at 21:31

Never gonna get lower temps on stock cooler mate lol.

may be something to invest in in the future then

as of now im new to the ocing thing and i also have no funds hehe

thanks for the advice anyway

any tips on fairly priced, good air coolers ?

eggybob · 9 Jul 2011 at 08:21

how is the arctic cooler freezer 7 rev 2 compared to intel stock cooler?

I know its fairly cheap does this mean its not much better than stock Intel cooler?

whipgeez · 9 Jul 2011 at 09:42

coolermaster hyper212+ is a great cooler for the price

i have a freezer 7, and i would say dont buy it. save for something better, the cheap ones dont really help. with the freezer 7 you are good up to arond 4.2GHz before temps start going into the high 80s under load, which just isnt worth the £15-£20.
idle temps will drop by around 10c on what you have now, but it just cant coupe underload.

when we say load do we mean just prime95 cause i play eq on ultra settings and wow on ultra settings oced at 4.4ghz i5 2500k with stock cooler and never go over 65 degrees c. these games are fairly old though would i see higher temps with say crysis 2?

i find prime goes into the 80s and gaming into the low-mid 60s, so appears very similar to the stock cooler for this.
