Overclocking Help to overclock i7 930 and Gigabyte UD7

I want to get 4ghz+ and have my memory run at its rated speed as it supports Intel XMP profile.
Please check sig for details.

I was looking to set the QPI to 20x200mhz with turbo off.
What voltages do I need to change, and what would be the max?

Thanks,

Simon.

 

As you most likely know, YMMV but I run my overclock at 1.3125V (it can run at 1.3V but I want a little extra security). All other settings I've left on auto.

That's with a forced 21x multiplier and 194 BCLK though.

 

with a 930 you will get a x21 multi with turbo off.

heres my 920 settings:

speedstep enabled
turbo off
BCLK: 200
DRAM: 1603Mhz
CPU voltage: 1.31250
CPU PLL: 1.90
QPI/DRAM Core voltage: 1.3
DRAM bus voltage 1.64
LLC disabled.

everything else is auto.

 

Ok, thanks.

I can get 4ghz but its not stable using Intel burn test.

Performance enhance: Standard
Turbo mode: Off
HT: on
QPI: 20 x 200
Memory multiplier: x10
XMP enabled (ram runs @ 2000mhz 9 9 9 24 1t 1.6v)
Vcore Set at 1.3v in Bios (CPUZ reports 1.26v)
QPI VTT: 1.51v
CPU PLL: 1.8v
QPI PLL: 1.3v
Loadline calibration: Level 1

If I drop my QPI VTT to 1.3v and increase my Vcore to 1.35v it wont post.

whats your uncore speed at ?

it should be 2x RAM speed +1 multiplier giving 4200 and that is a very steep order

 

Uncore is set at 4000mhz The intel XMP sets the memory to this.
Qpi link is at 7.2ghz

 

Try under-clocking your RAM while you're pushing the CPU. Sometimes the RAM can introduce instability that's hard to differentiate from the CPU not coping.

Regarding CPU vcore - I run around 1.25v for my 3.8GHz. Although people have done it, I would not go above 1.35v as a general rule on these i7's - at least not for any permanent overclock.

 

This is a really good i7 overclocking guide.

Ok, I will have ago at that. What would be the max setting for the QPI VTT Cause past 1.31v its highlighted in pink.

 

its proberly not helping having 6 sticks of ram as it can put more strain on the northbridge ( i think )

 

thats correct but there is no northbridge anymore its on the CPU so to speak so extra heat and strain on the 930 instead. It shouldnt be a massive issue but it can lower the Max overclock your able to achieve.

 

Oops my bad, I only got 3x2gb sorry for the typo. I will address the sig.

 

Isn't the QPI Link speed too high? Or does the 930 run that high? I'm sure my 920 @ 4Ghz runs at 4.8

ninja edit: I'm pretty sure the 930's link speed is 4.8, too - spec

Might just require a little more juice on the cpu if the vdroop is to be believed.

 

try nudging the PLL to 1.9v

 

QPI@7.2GT/s!!!

I'd set that to 4.8 pronto.

At 4000+MHz on the uncore, things can get dicey and need the voltage turned up.- lucky you're watercooled!

I recommend following what this guy did. Sure it's for a different mobo but the numbers should transfer across.

EDIT: Here's a better guide.

 

You may need to increase the VTT to 1.6v+ for 2000MHz. As suggested above try dropping the RAM speed as low as it will go. My Trident needs just over 1.6v to run at 2000MHz with a 4.2GHz overclock and 1.475v to run at 1600MHz with 7-7-7-20 rather than 9-9-924. It still needs 1.375v to run at 1200MHz.

You shouldn't need more than 1.6v on the DRAM voltage though unless you overclock it but then the QPI/VTT volts get silly.

 

Right I have now got it stable at 4ghz and memory at 2ghz 9 9 9 24 1t.

Idle temps 45,44,44,42 (been on for a few hours) Max Temps 100% Load With Intel burn test 76,76,74,74. Outside Temp 22c.

20x200
Turbo off
XMP proflie 1
Uncore 4000mhz
QPI @ 7.2ghz
Vcore 1.325v in Bios (CPUZ 1.312v)
QPI VTT: 1.59v
CPU PLL: 1.9v
QPI PLL: 1.4v
Loadline calibration: Level 2
Dram voltage 1.60v

thats not reallt necessary - i have mine set at 7.2GT/s - its stable.

 

turning hyperthreading off will drop temps quite a bit, it just depends on if you need it or not, i find for gaming it pretty pointless

 

Thanks for all the help guys!!

Been stable for the last few hours. Idle is still at 40-45c. Which I'm happy with considering Outside temps peaked at 26c.

Cheers,

Simon.
