i5 760 msi p55a-g55 Overclocking help needed.

[flip-it3]

I tried to OC when I first got my rig but I couldnt figure out how to lower the Vcore... it would say auto and would only go up... But im trying it again.

Here is the safe settings, normally multiplier would be set to 21:

When I tried to OC I set the cpu freq to 180 and lower multiplier to 20 to get 3.6ghz... but when I check it using cpu-z program the voltages are around 1.4 which is much higher than it should be. Most OC the i5 760 to 3.6ghz under 1.20v but im not sure how to lower it in my bios...

here is the image of the voltages, they are set to auto and Im not sure how to lower them. When I try to change the cpu voltage I can only go up by increments of +0.025 or something like that so Im confused how to get 1.2v on my motherboard...

Can anyone help? It would be very much appreciated.

Thanks!

It's not that I dont know what to do but the way I adjust the voltages on my bios is different.

When I try to change the cpu voltage I can only go up by increments of +0.025 or something like that so Im confused how to get 1.2v on my motherboard...

No guide Ive seen has only increasing increments +0.000 so that's why Im confused.

What does it do if you choose +0.000 in bios? Did you try it? Not sure but I'm thinking it'll run at whatever stock is plus zero volts. Try it and see.

 

[flip-it3]

Yea I guessed the same thing, there was no option for +0.000 only +0.002.

I tried that and set my vtt to 1.19v with cpu freq 3.4ghz. During idle cpu-z would show the cpu voltage to be 1.2v but when I ran prime95 for stability it was 1.14v... it was stable for 15mins of testing but got up to 85C at one point.

I turned off all the powersaving options so idk why the voltages are fluctuating. I tried other tweaking but same thing would happen and then it wouldn't be stable with prime95 testing.

I disabled everything on that menu during oc.

I'm just trying to find a optimum voltage to get me to 3.6ghz but the adjustment of the voltages in my specific bios is confusing compared to other guides ive seen.

 

[Spikesoldier]

try doing this:

Vcore: + .150 or + .175

Vtt: 1.33v

PCH 1.05v: 1.1v

CPU PLL: 1.9v

Multiplier: 21 (You will have an easier time OC'ing on an odd multiplier)

BCLK: 176 (will give you 3700 with 21x multiplier) [195x19 looks good too]

 

[flip-it3]

The Vcore goes up by intervals of +0.006 and it goes into the warning area after +0.024.

I set the vcore at 0.006 then used your other values (set vtt at 1.25 though) but clocked at 3.0ghz just to make sure it's stable at lower speeds.

idk if I should be worried or not. At idle the cpu voltage was 1.24 then when running prime95 the voltage went down to 1.21...

here are my full specs:
i5 760
msi p55a-g55
mushkin 4gb 1333
coolermaster hyper 101
5850
corsair cx600

Ok, first rule of overclocking (well, maybe not, idk)... NEVER leave it on auto.
I have a very similar setup to you: i5-760, msi p55-gd65, 8gb 1333.

When I was first messing around with the overclocking on it I didn't really know anything about overclocking and threw it up to 4.5ghz with vcore on auto (I was finding the max bclock and just left the multiplier on default).
I wondered how it was being prime95/intelburntest stable without raising the stock vcore, but auto doesn't give it stock, it gives it whatever the motherboard decides it needs.
My msi board decided it needed 1.55v... I got a little nervous when I saw that in cpu-z, but these chips are really strong overclockers, so no harm done.

Anyway, just bump the voltages up or down one notch if you don't want it on auto.

For my computer, I decided I didn't need 4+ghz all the time.
My 24/7 overclock is 3.66ghz @ 1.195 vcore, 1.112 vtt (166mhz bclock, x22 multi) and has been serving me well.
This is with all the power saving features still on and turbo boost enabled, so it's not constantly heating up my room...

edit:
Just saw another part of your post, yes voltage should drop under load.
If you change high vdroop to low vdroop you probably won't see that drop, but I wouldn't recommend touching vdroop.

 

[flip-it3]

Yea Im aiming for 3.6ghz. Is the 1.195v after the droop or before?

Also did you have the increments of cpu voltage (+0.006) or did you have the normal bios?

I just ordered the Corsair A70 for $30 on sale so hopefully I can stay under 65C on full load.

I'll try to hit around your settings.

That's what I set it to in BIOS.

I guess I have a 'normal' bios, I didn't look close at your screen pics until just now, since they look almost exactly like mine; you may want to try updating your bios if it's not up to the latest.

My zalman 9900 keeps the processor cool all the time, and it's way quieter than my 470... so with water you'll be more than fine.

EDIT--------
lol, thought you said H70.... a,h, whatever

You can see the voltage thing in these screens, I just ran intelburntest for a little bit and took a shot before and during.
