Got to ask "i need help"

Sgt Tackleberry · 20 May 2011 at 23:35

hi guy's and girl's

2day i set up my sandybridge set up spec:
i5 2500k "oem"
GA-z68x-UD3P-B3 mobo
8gb xms3 1600mhz
rest of the stuff is in my sig.

I have overclocked my other systems fine and i know what i am doing BUT this time i am stuck and need some help from
you guy's n girls

.
At stock speed my vcore is 1.295v as soon as i drop it i get BSOD, i've tried to overclock to 4ghz but i wants 1.35v to get it there..
Something is wrong or i have a really bad batch on my cpu..

i have taken seom screen shots of my bios, can someone point me in the rite place on what to turn off/on/disable/enable/auto or what.

any help would be gr8

Thanks

Bump for some help plz...

I've been trying to get this overclocker all night now and nothing.
I've updates the bios still no joy!, I can't get 4ghz stable not unless it has 1.35v.
Please help... Might have to go back to my i5 760 at this rate!.

It looks like you have the Vcore on auto and like all P67 boards auto tends to use more V than it needs so bad chips wont go short.
Set it to 1.3V and 4GHz and see how it go's then take it from there.

Sgt Tackleberry · 21 May 2011 at 11:59

I have set the Vcore up to 1.35 but it's not stable at 4ghz! Only way it's stable at 4ghz is at 1.45v

Right the first thing you need to do is download the latest version of the EFI Hybrid OS based bios. It works a dream with the Z68X board you have.

Find it HERE

Latest BIOS GA-Z68X-UD3P-B3 bios (F4c): http://91.121.148.119/downloads/BIOS/Z68XUD3P.F4C

Update your BIOS to the latest offical version
Boot into BIOS
Reset to default values
Boot into OS
Install the EFI OS based BIOS
Select Profile 1 for your ram
Change your CPU multiplier to the desired number in your case 40x
Go to the voltage section
LLC 5
VCore 1.4
Vtt auto
PLL 1.76
All the rest on Auto
Now go to advanced CPU functions
Disable turbo
Leave all the rest auto
F10 and enter

I will check back a little later to see how it goes
Now lets start from the beginning if you do not mind.

Thank you.

I'm at work now but when I get home about 7ish I will give all that ago.
I do have the latest bios.

Right once you have done that then you play your favourite game. Or what ever is your most stressful application that you use daily. That is your stability test. Those other applications that people swear by are a total waste of time with SB all they show is that SB can complete ten million hours of what ever stress test it is. And then promptly fails playing WOW on line. Real world for real world stability. I will check back after 8 tonight then.

Later.

mmmm - i like this stability method!

I love your thinking

..

I will report back 2night. I should be in hopefully on time 2night, it's rather dead here 2day.

Hello 1day,

I have done all of the above but set my vcore to 1.35v and up to the multiplier to 46, and set the DRAM volts to 1.5v as when i was checking it it was saying "1.65v".

So at the mo I'm running 4.7ghz @ 1.36 stable so far

if i go any higher with them volts and upping the multiplier my system wont boot at all.

What is Vtt? can i turn that up or should i just leave it at auto what is 1.05v

any more tips?..

Thank you.

I got a little sucked in on stability testing with linx and prime long runs on my overclocked 2600k.
Passed them with flying colours and still had the random blue screen crash from desktop.Its a strange one.

1kiwi · 21 May 2011 at 20:51

Prime Blend will expose any instability with SB in my experience.

If you have enabled Profile1 and there after saw 1.65 that is correct and how it should be. You see the profile will set is what the ram has preprogrammed in it. In other words that is the voltage the ram is meant to run as per the manufacturer.

So at the mo I'm running 4.7ghz @ 1.36 stable so far And I hope you are not complaining about that.

if i go any higher with them volts and upping the multiplier my system wont boot at all. That is because you have not enabled PLL overrider and I do not suggest you do so for 24 7 use.

What is Vtt? can i turn that up or should i just leave it at auto what is 1.05v Vtt is he voltage that is going to your CPU's memory controller in simplistic terms the harder you push your memory the more Vtt you will need.

any more tips?..

Thank you.

The most important tip is to keep an eye on temps. Let temps be your guide. So log your temps using which ever application you prefer and play a game or what ever it is you do. Then go and look and see what the max was.

Voltage alone does not kill a CPU. Voltage and heat kill CPU's :eek:

Yeah that is the thing. A stability test is showing only that the system has passed that particular test. The demands that real world applications bring to the table are different and no one test can predict the unique needs of each and every user. They do have a value I guess. Bragging rights of a different kind. I like to bench my system and see how fast I can get it for short bursts. These guys do a very similar thing. Just the duration is different. Ones a sprint and the other is the marathon. Personally I like the strong muscular build of sprinters more than those skinny ones of marathon runners. My husband is neither sadly. More a walker one could say.

Sgt Tackleberry · 21 May 2011 at 21:25

Thank you very much 1Day.

Temps will not be a problem as i am running on a custom waterloop.

I bring the vcore down n by a notch now, so far i am at 1.32v, temps with that r idel 25'c and full load 45'c.

I've seen people push the SB chip to 5ghz + on silly amouts of vcore. I've try all the way upto 1.5v and still can't get 5ghz why is that?..

once again thank you for your time and info

To get to 5GHz you will need to enable PLL overrider. That is the only trick.

PLL overrider = Internal CPU PLL over-voltage.

Set to enable.

Set 50x or 51x multi and make sure your volts are at least 1.440 and you will be in the 5GHz club once you have run Super Pi 1Mil.

Lol you say your huby looks like the walker type! cant you atleast beef him up a little and promote him to the power walker type.
Anyways moving on lol, Ive noticed you mension a couple of times about setting pll voltage at 1.76 is there any benifit to reaching your max overclock with this?

1Day · 21 May 2011 at 22:09

Yes I have noticed that there is a benefit with a lower PLL - on the boards I have used lowering the PLL resulted in a reduced thermal signature on the CPU. And when I dropped the PLL I was able to achieve a better max stable overclock. Bare in mind that unlike many others I do not disable HT or any of the cores to achieve a max over-clock. So temp management is quite important. I do all my testing on water or air, for example my 5.7GHz super PI was run on air the first time. It was only later on that he that walks

bought me a Single Stage.

Geeman1979 · 21 May 2011 at 22:16

Well im currently stuck at 5.350 and a few pence but I will push harder

1kiwi · 21 May 2011 at 22:20

If you board is anything like mine use offset voltage and LLC otherwise you will suffer a drop in voltage on load (vdroop).
