Core i7/X58 Overclocking Thread

[Avid6eek]

I don't post much here, but I figured I'd throw this out there so everyone can get a better understanding of how the i7 overclocks.

Stock Intel heatsink:



Since I'm on the stock heatsink I disabled 2 cores to try and lower temps...saved me a whole 2C but doesn't allow me to OC any higher w/o causing instability.

Which motherboard are you using?

Have you tried to drop the multiplier to 12 and overclock the base clock to the maximum to see how much further it can go?

This is on the Asus Rampage II Extreme. I haven't tried pushing the base clock yet. I will in the near future.

My 920 in a 29deg celsius room temperature, just fooling around to see low vcore stable, EX58-UD5, XMS3 1520mhz, True black air cool. Vcore set 1.31v and QPI/VTT 1.24v, dram 1.6v that's all.

It would be nice, if every one post their BIOS settings.

3800Mhz @ 1.28v
26º/31º Idle
60º/65º full














16500Mb/s & 28ns












Setings:

Multi: x19

thnks to user gligy for the bios settings !


regards

Agreed, thats kinda the whole point of the thread of you think about it. With ever person that posts up bios and system specs it gives us a better overall picture of the i7. I'm still waiting for a couple parts to come in, but I'll post in with bios/pics when I can.

2nd boot


4Ghz @ 1.36v (1.33 Full)





I only run SPi and everest , didnt tested with prime yet !


regards

[ShoNuff]

@mascaras...nice results...congrats. I would have been happy with 3.8GHz at 1.28v. I hope I am as fortunate. I don't get mine until tomorrow.

Thank you and gligly for posting the bios settings.

Hi

been testing 920 Costa rica A
3835A766

Cpu @190 x 20 3800
cpu @1.325
Qpi =1.28
Dram =1.64
Turbo mode enabled

mem is run @ 1520 (not too bad)
but have made mistake of geting corsair 1333 tri channel

should have gone for 1600

if i lower the mem x to 6 and uncore to 12 so 200 x6 =1200
computer will not boot

thanks to gligly for orginal advise on volts

cheers

Loadline ON 1.35v bios, 1.328 idle, 1.31v load is small ffts stable (12+hrs, pic below)
Loadline OFF 1.39 bios, 1.36 idle, 1.31 load is small ffts stable (9+hrs, pic previous post)
overshoot should be .08v from 1.31v in both cases (if GB followed intel recommendations and overshoot =bios setting loadline off - load v)....so for me LOADLINE ON FTW.

Bios F3, 182x22, turbo on, (turbo tested prime stable by setting affinity to cores 0/1).
QPIx36
uncore 18x (18x182 or 3276mhz) w/1.28v qpi/vtt (for 20x w/182blck need 1.32v)
pcie 100
performance turbo
8 mem divider (for now, OC last, need 9 mem divider)
DRAM 8,8,8,24 at 1.60v (rated 1600 1.65v)
rest stock/auto, all that matters on mine is above settings.

[mascaras]

Hi again





Settings:

Multi: x19
BCLK:200
Performance : Turbo
RAM: DDR3-1600Mhz @ 9-9-9-24
Loadline : Enable
Uncore : x16
Memory : x8
QPI/VTT : 1.26v
Vdim : 1.60v
Vcore : 1.31v Bios (1.264 Full)
CPU settings :BIT & Multi Core ON , rest All OFF



3800@ 1.264v





i will try lower the vcore and see if runs prime95

Is that stock cooling mascaras?

naaa , watercooling !

these chips are Hot !!

[roller11]

sure, enabled u can set 3 settings,
auto
pwm
voltage.
same with F3 bios as the F4e bios.



ok.
Thx.

Thanks Flopper. Not the answer I was hoping for, but you saved me from ordering a mobo and then having to send it back.

[ap4lifetn]

just checking, mine is at 3.2GHz w/ 35C idle on stock cooler, if you got to 3.8GHz with 35C i would have been insaaaaanely jealous

hehehehe


btw: if anyone interested , i posted a few tests with Core I7 920 & Gigabyte GX58-UD5 here >> http://www.xtremesystems.org/forums/...d.php?t=208811

? bug in F4e GB extreme bios where 23 multiplier (turbo) always active, (would not think that even possible?) When priming 8 cores, multiplier should be 22 (turbo only active with one core) but multi stays 23 per cpuz with all 8 cores loaded only on F4e bios, works correctly F3 bios. Also, F3 prime stable 12 hrs, but same settings in F4e crash immediately almost as if really running at 4.186...(though could be memory channel subtimings were different as well in F4E). Anyone else run into this issue? to late this pm to try and figure it out...

This is on the Asus Rampage II Extreme. I haven't tried pushing the base clock yet. I will in the near future.

Hey, what is your motherboard revision (it's written on the board)? Also, what BIOS version did it ship with and which BIOS version are you using now?

[Guacamole]

I'm working on 4.0 with my Gigabyte EX58-UD5 and i7 920 It's a little work but I think I can get there Vcore is a little stronger than I would like, but the board has blown me away how graceful and perfect it Overclocks.. I haven't ever really owned a Gigabyte because they always seem to leave out some feautures that I love (esata) but I am absolutely astonished at how much quality this board brings to the table for the price... I suggest this board without reservation for anyone considering an X58 build I will post my settings in the morning...

Hi

hmmm it seems F3 bios is better ( im using F3)

, but the board has blown me away how graceful and perfect it Overclocks..

yep , im also enjoying the UD5 , really great mobo , the only problem i found is that i need to use the White Ram Slots , if i use the Blue Slots the system wont boot ,(2 friends also had same problem) do you have same problem??

as per manual for 3 triple channel start with white slots http://i4memory.com/f90/gigabyte-ex5...os-info-11500/

Oh, I am gettng so excited, that stuff can't get here fast enough...

What ram are you running...

[nbarsotti]

Hello, I am trying to overclock my MSI X58 Platinum and i7 920. Can some tell me a software application that will tell me what the current QPI voltage is? The MSI does allow control of that voltage but it does not ever show what it is in BIOS. The auto setting for CPU voltage does not work correctly when over clocking so I do not trust the QPI voltage to the AUTO setting. Thank you.

...fixed in this version: CPU-Tweaker-beta2

I didn't notice this before but CPU-Tweaker 1.0 beta2 shows the Bus @ 195.6MHz along with some other changes.

BIOS Settings:
CPU Ratio Setting: 20
BCLK Frequency: 190
DRAM Frequency: DDR3-1573
DRAM Timings: All Auto



I then checked the stock setting and now CPU-Tweaker shows the Bus @ 137.6MHz.

BIOS Settings:
CPU Ratio Setting: 20
BCLK Frequency: 133
DRAM Frequency: DDR3-1066
DRAM Timings: All Auto



I looks like that CPU-Tweaker is adding 4-5MHz to the BCLK BIOS setting. Now am I the only one that is seeing this?
