Core i7 4Ghz Club & Overclocking Guide

Does OC palm show core temp or just cpu diode?

It just says cpu temp. It's always lower than real temp.

I`m from Brazil and just bought the rampage II extreme and tge core i7 920 D0, but i can`t overclock to 4000 or 4200

my memos are patriots viper 6g 1600

i have an air cooler

can you help me with the overclock?

Received via PM from Wsarahan

Hi Sarahan Welcome to PureOC.

First off i will need you to provide your full system specs before we can help you with the OC of your D0.

We will need to consider the type of PSU your using, the Cooling: HSF or Liquid etc...

Update your system specs I can advise you accordingly.
In General, D0 needs about 1.28v-1.35v to get to a stable over clock of about 3.8ghz-4.2ghz
Temperature needs to be a consideration when overclocking.

Hi here are my system specs

Core 7 i920 d0
Rampage Extreme II Bios 1306
6 gigabytes Patriot Viper 1600 with XMP
Air cooler Tranformer 4 with the fans changed to better ones
Gpu Radeon 4870 x2
Psu Zalmman 850 watts
Vista 64 bits

So, i can`t overclock since yesterday, please help me

Thanks

It just says cpu temp. It's always lower than real temp.

So it's not reading core temps, it's just the CPU diode temp that is why it's lower the RealTemp.

Have you try the RE2 Bios table sample?
We also need you to post your full complete Bios settings.

Regarding to cooler, I'm not familar with your so my best guess you won't get it pass 4Ghz.

What is RE2 bios table sample?

In bios I have the option to choose wich bios i`d like to use

Bios1 - Default
Bios2 - Performance

I`m using the bios1 now, thinking try to use the performance one

Sorry I`m from Brazil and my english is not soo good, can you explain me what is it?


Bios settings is:

Ai over - manual
Cpu turbo - enabled
cpu ratio - auto
bclk 200
pcie - 100
dram 1603 timings 9 9 9 24 set manual
uclk - auto
qpi ink - auto
epu - full phase
load line enabled
cpu differential - auto
cpu voltage in bios - 1.33750, but i`m trying less
qpi auto
dram bus voltage - 1.65
cpu spread auto

Advanced

ratio - auto
c1e - disabled
hardware prefetcher - enabled
adjacent - enabled
invel virtualization - enabled
cpu tm - disabled
execute disable bit - enabled
intel ht - I want it enabled but with disabled the temps are very coolder
a20m - disabled
speedstep - enabled
turbo mode tech - enabled
c state - disabled

Thanks

I mean RIIE (Rampage 2 Extreme).
these Bios table Core i7 4Ghz Club & Overclocking Guide

I see you have a lot of setting are still on Auto. You need to set them manually you will have more chance to get it stable. Your RAM is XMP ready, you should select XMP profile instead of manaully setting. This is will save you a lot of headache.

First you should try to disable the Turbo, get it stable then enable the Turbo later. You do need to increase the CPU, QPI/DRAM voltage when the Turbo is on though.

So try one of those samples but set your RAM setting accordingly to your specs, if you have a problem then post back the bios.

Thnaks, but what settings i should set manually? Can you give me some tips? And should i use the bios1 - normal or bios2 - performance?

Thanks

Sarahan,
try this settings and i am starting off with 1.35vcore, Since it is a D0 i would think that you will require much lower vcore but if you can get your system stable with this settings ... we can work downwards until you find the lowest possible stable vcore

Lets start with 191 bclk x 21 Multi (turbo enabled) = 4ghz

You should try Benchwarmer's bios setting since you are using air cooler. Disable the Turbo and test for stability, keep an eye on the temperature.

Study closely those 3 bios samples, you will see which setting should leave it on Auto and which one you should manually set them.

About Bios 1 or 2 you have to wait for Bully to response. He has the same board as you, I know RIIE has two bios but I'm not familar with it.

By the way, you have 920 D0 version therefore your CPU voltage will be less than Benchwarmer voltage. So work your way down to find the right voltage needed, I best guess is somewhere 1.25-1.30v.

Thanks but 191 x 21 = auto + turbo, i can`t set my memos to 1603 in dram frequency, it`s 1531 or 1914

Keep it at 1531 first, once the overclock is stable we will work towards 200bclk which will take the rams to 1603mhz

and should i use bios1 - normal or bios2 - performance?

This option: Execute Disabled bit is to set disabled?

One doubt, why do not use the xmp profile?

Thanks again

[bullydog]

What do you mean?

This option: Execute Disabled bit is to set disabled?

Yes disable it

One doubt, why do not use the xmp profile?

does the Patriot Memory have built in XMP profile? If yes you can use XMP

[wsarahan]

What do you mean?



Yes disable it




does the Patriot Memory have built in XMP profile? If yes you can use XMP

In the bios menu i have 2 bios options, normal or performance

Just a opinion, do you think i can get 200x auto + turbo that is = 4200 stable here?

If yes how much vcore do you think I will i need to get 200x auto + turbo

another question hehehhe, wich is the temp limit to get on prime running? and how much time do I have to run each time I`ll try to downgrade vcore?

Thanks

U are you air cooler, very slim chance you're going to make it pass 4Ghz with HT/Turbo on.
4Ghz with HT/Turbo on with a good air cooler is possibility.
Keep load (Prime) temp under 75°c is the ideal.

Not using Ht here, ht the temp is too hot

I`m trying 4000 + turbo xmp whitout HT
