how much more can i go on stock volts?

MiNxYyY · 19 May 2008 at 15:16

currently at 3GHz 375 * 8 @ 1.3000 V and ram set to 1/1

is it possible to get mayb 3.2/3.3 on stock volts if i keep multiplier set to x8?

Maybe 3.15-3.2ghz if you're very lucky.

if i wanted to achieve a stable 3.4,what is the best voltage for this?

also,my temps have dropped by 11 degrees since i set my cpu to run at 3GHz

Cob · 19 May 2008 at 15:22

Every chip is different, so there's no standard voltage for 3.4ghz.

You'll likely have to go to atleast 1.4v in BIOS for 3.4ghz, possibly more.

Not sure why you are affraid of raising the voltage a bit.

Increase the FSB to 400MHz (multiplier of 8 = 3200MHz) and you'll be flying. I have mine set at 1.4v but it never uses all that. You should be able to go onto 425MHz (3.4GHz) from there. Watch those temps though. Make sure you do a stress/temp test each time you do a new OC.

edit - confirms cobs post

so should i set voltage to 1.4 to get 3.2? or will 1.3 be just enough?

Cob · 19 May 2008 at 15:30

Test and see.

Every set-up is different.

MiNxYyY · 19 May 2008 at 15:36

ok set to 400 x 8 and got 3200,loaded into vista first time,idle temps are 54/57,going to run COD4 now to see if its stable .

is everything looking ok?

Zefan · 19 May 2008 at 15:39

What are the load temperatures?

Cob · 19 May 2008 at 15:40

Idle temps are crazily high. Is that the stock cooler?

And is that set to 1.4v in BIOS?

Admiral Huddy · 19 May 2008 at 15:42

I would give this a read.. Temps look too high.. Mine are around 32 idle.

Don't be affraid of increasing you voltages. As long as they are small increments, you won't do any harm. The system will just fail to boot if it's not receiving enough juice and just won't POST.

MiNxYyY · 19 May 2008 at 15:42

its AC 7 Pro,BIOS voltage is default (1.3000)

Admiral Huddy · 19 May 2008 at 15:45

Have you applied the correct amount of TIM or did you stick with the AC thermal pad?

Do you have plenty of case fans?

MiNxYyY · 19 May 2008 at 15:46

stuck with the ac thermal pad,i have a some Arctic silver 5 paste here,not used yet,is it worth applying it now?

MiNxYyY · 19 May 2008 at 15:55

these are temps under 100%load

Cob · 19 May 2008 at 15:58

That's only one core tho.

The paste that comes with the AC7 should be fine tho.

Admiral Huddy · 19 May 2008 at 16:10

do you have the AC CPU fan blowing in the direction of a rear outlet fan?

What other cooling do you have... Seems really high for idle.

It's odd becuase if your starting idle temp is in the 50s, i'd expect the load to be a lot higher than in the 60s. I'm wondering if the CPU fan is spinning correctly when idle.

MiNxYyY · 19 May 2008 at 16:27

the cpu fan is facing the front of my case with the air being blown out the back were another fan is sucking out also,i have 4 x 120mm fans on the side of my case,1 x 120mm at front,1 x 120mm at back,1 x 120mm as the top,i have a 3-pin fan blowing directly onto my cpu,i suppose i could get my really big fan and blow it straight into my case..

Admiral Huddy · 19 May 2008 at 16:30

nope they should be fine.

Does the fan spin on idle?
