4.2ghz Help So close!!!!!!!!! AHHHHHHH

[exodus1337]

THANK YOU STABLE 100%

Intel i7-970 4.2GHZ

Asus Rampage III Formula

EVGA GTX 570

G.Skill Low Latency Memory

BCLCK 200

MULTI 21

LOADLINE CALIBRATION FULL

CPU VOLT 1.337v

CPU PLL 1.88v

DRAM 1.65v 6-8-6-20 1t 1600mhz

CPU AMP 800mv

CPU CLOCK SKEW NORMAL

IOH CLOCK SKEW NORMAL

IOH 1.2v

ICH 1.2v

First of all stick the clock skews back to auto.

Also you are not really gaining much by running your PCI-E @ 110MHz leave at default 100MHZ

Enable Load Line calibration.

Then CPU PLL to 1.88V

IOH voltage to 1.2 - 1.25V I'm pretty sure this will be your problem. IT's the X58's NB

You should be able to hit 4.2GHz with what you Vcore is set at and you QPI/VTT voltage is fine for 1600DDR3.

Give it a go anyway!

What about the ICH shouldnt they be set close to the same?

What about the ICH shouldnt they be set close to the same?

No ICH is the southbridge voltage. Completely separate.

 

[exodus1337]

Thank you bro...I noticed a little higher temps though... with lower volts with 50% calibration... how can that be ? when you have no calibration on does that mean it can hit the voltages you set but doesn't always keep it there...?

do people ever disable calibration and turn on TM function.... I don't understand why the temps were so much lower with load calibration off...

 

[S1EJ0]

The load line calibration prevents voltage drop and droop. So if you set it at 1.35V in BIOS the LLT will keep it at that value. You will notice if you use CPU-Z in windows the CPU voltage will be lower with LLT off than wht it is with it enabled.

As for the TM function I would leave that enabled as it's a thermal protection feature so you don't fry your chip.

 

[exodus1337]

Ive been reading that when you use a higher pll voltage it allows vcore to be stable at lower volts... is this true?

 

[S1EJ0]

Not really. Upping the CPU PLL I've found just stops ramdom BSODs.

Some people recon lowering it is good but I can't see how using less than Intels' spec is good. I would have thought it would make it less stable especially at higher clocks.

 

[exodus1337]

U are absolutely right!! I love it... unless i use 1.88 or around that i get random BSOD!!!! thank you for your help!!!

 

[exodus1337]

Where do you find the volt spec for your processor? Oh and what do you think of bumping the pcie frequency higher then 100 ?

 

[S1EJ0]

My link for cpu specs.

Leave PCI-E frequency alone makes no difference as there is plenty of bandwidth. Maybe if you running multiple SLI with high OCs you may see a difference but not for a single card running x16. By all means play with it run some benches and see for yourself. I wouldn't go higher than 105-110Mhz though as risk of currupting you HDD data increases quite fast.

Have you got your system stable @ 4.2GHz then?

 

[exodus1337]

Hell yea brother! It's funny... I looked at my volts and there at 1337!!!! ahahahhaahahah!!!!!! 1.337, CPU PLL 1.88, IOH 1.2, ICH 1.2, CPU Amp 800mv, Loadline Full!! It smashes on the i7-2600k even at a higher overclock such as 5.3ghz.... I guess those 2 extra cores own!!!

5.3ghz 2600k http://www.youtube.com/watch?v=mNdRO3sBVAg

I run Cinebench with prime95 and still own him!!!!

 

[exodus1337]

Also here is my 3dmark score !!!

 

[S1EJ0]

Glad its all working for ya.

The two extra cores make a big difference on R11.5 as it is a multithreaded bench test. I get just over 12 points running @4.8Ghz

I can't see your 3DMark score.

DAMMMMMM ur insane I wish I a better water cooling setup!!!!
