Try these settings @4ghz:
Memory Multiplyer: x8 (for 1333 RAM)
QPI Frequency: Auto
QPI Voltage: +040mv
Spread Spectrum: ON
Did these on my Area 51 (non-ALX) i7 920, BIOS A09, 1333MHz memory
got the 4GHz
CPU cores idle at 43C, full load under Prime 95 ==> 77C GULP! Stable for 1 hour, plan to run 10h or to rethink since temps >75C
temps for 3.67GHz settings were sweet. no problem
can someone please confirm if I can overclock to 3.67 with 1066mhz ram? Would it be safe as in that I wouldnt have to buy new ram lol? I have a aurora i7 920, 12gb 1066mhz ram, win 7 64 bit, ati 5870...thanks.
4.2GHZ Stable (constructive criticism welcome)
Memory Multiplyer: x6 (for 1333 RAM, which gives 1200mhz, seems mine didn't like being at 1600mhz and randomly crashed in games))
BLK: 200 x 20 (actually 21x, read on!)
Spread SPectrume: OFF
Turbo: On! (speedstep on and c state off, this gives 21x multi Also need to go to power managment performance in Windows and turn CPU usage to 100% all the timne to prevent it dropping back multis. Voila! 21x 200 is giving me 4.2GHZ
Admittedly runs a little hot, peaks at 79 degrees in Prime95, but very very rarely gets there with regular gaming/usage and only for a few seconds. I figure I can live with this, I will probably want to upgrade in 2-3 years and figure even with high temps should last this long. Thoughts anyone???
Considering buying 12GB 1600mhz or higher RAM so I can kick up memory multi and double my RAM from 6GB- anyone think this is worth it? Also want an SSD- thoughts?
Thank you, VasVas. I used the settings you listed, above, and managed to achieve a stable overclock on my Intel i7-930 QC at 4 Ghz. I ram Prime95 for over 24 hours with no problems. Here are the settings that I used. Most of them are the same ones you used for your overclock:
Memory Multiplier: x8
Bus Clock: 190
Memory Voltage: 1.60V
IOH Voltage: 1.20V
QPI Frequency: Auto
QPI Voltage: +040mV
Spread Spectrum: Off
Turbo Mode: Off
Intel i7-930 QC
20 GB DDR3 PC-133 1333 Mhz RAM (24 GB as soon as my next package arrives from Dell )
ASUS EAH5970 2 Ghz Dual-GPU 2 GB DDR5 VRAM
19 x 1 Media Reader
Blu-Ray/DVD/CD RW+/- BD-RE Drive
300 GB WD Velociraptor SATA II HD @ 10k RPM
1T Seagate Barracuda HD
1.5T WD HD (2) (non-RAID)
1T Seagate Portable USB HD
Soundblaster X-Fi Fat1ty Champion Soundcard w/ Front Bay Control Panel
Bigfoot Networks Killer Xeno Pro NIC
Hope this helps out anyone who has an Intel i7-930 QC and wants to overclock it! Kudos and my humble appreciation to VasVas for the original post
How hot is too hot ?
I tried the settings, and after a minute or so of Prime95 I was up at 84C on one core and so I shut it down.
Aurora ALX, i7 920, 3.2Ghz, BIOS A11, 875w, 6Gb DDR3 1333, single HD6870, 1Tb SATAII 7200RPM, 500Gb SATA II, TactX mouse/keyboard, Dell 1901FP monitor, Logitech 5.1 speakers, Epson RX580 MFP, HP Laserjet 4, Win 7 Home Premium 64bit, CC 188.8.131.52
Depends who you ask it seems.
Personally I don't want mine to go past 80 at all, as per previous post, min touches 80 on and off but only for couple seconds then back into high 70's on Prime 95 @ 4.2Ghz or on other CPU intensive tasks- that I can live with. But anything over 80 for me from what I have (extensively) read is too hot.
While playing round with mine had my vcore way too high at one stage and hit 92 C in Prime 95, asked a mate and his eyeballs nearly fell out and told me was wayyyy too hot.
So short answer is turn down your volts until it is stable at your target oc, the volts creates the heat but increases stability when OC'ing, and I would be aiming for the same temp as mine or lower- 80C absolute max temp under load.
Someone will no doubt tell me I'm wrong though I'm sure- either I'm too hot or you could safely run hotter
Hi VasVas and all you Overclocking lovers out there! Thanks alot for the great Overclocking info.
I'm new to this Overclocking world, but I do understand about computers and its certain functions. I would like to give overclocking a run. Hate being a noob to these things but everyone has to crawl first before they walk right =)
I would like to Oc my i7 920 to 3.66ghz first then maybe move on up to 4.0ghz when I'm ready to.
I am currently on Bios A09 should the A09 be able to let me Oc@3.66ghz? Do I need to update to Bios A10 or A11 first in order to do so.
If anyone else knows about Overclocking and has succeeded with there Aurora's feel free to let me know Thanks.
Aurora: i7 920 Factory Oc@3.2ghz
12gb ddr3 1600mhz tri-channel ram
Single Ati radeon 5970 2gb
Samsung SSD 128gb / Sg Barracuda HDD 1Tb 7200rpm Raid 0
WIndows 7 64bit
Would recommend updating your BIOS for sure, always a good idea, irons out bugs etc.
Would also recommend doing extensive research so you fully understand OC'ing- there is no hard and fast rules from what I have discovered, and every machine and chip is different ie MY i7 920 may be able to OC higher than YOURS and vice versa.
Also would recommend when you are changing your settings in the BIOS to write everything down every time you fiddle with it, as you may hit some good settings, further tweak them and then not remember what the previous ones were.
Read through this thread a little more carefully, google i920 overclocking, visit overclockers.com etc and see how you go. Been running mine stable @ 4.2 for some time now after HOURS of fiddlign and research.
Also let us all know how you go and if you have any more specific questions.
Thank you pappsw for relaying the much needed info!
Like I said I'm new to the Overclocking world and I'm learning as I go =)
Like you said not everybody's Comp. & Chip are the same. No 2 are alike and only some can get lucky to have it maxed out O/clocked. I did read alot on the other forums ex.Overclockers.com and several other good O.C sites and they all helped. This Forum I really think helped me out alot more because in this Forum majority of us all have an Aurora/ALX with i7 920 and same Bios. With that said this is what is going on in my machine right as of now.
I updated the Bios to A10 this morning and started messing with the O/clocking and right now I am Oemail@example.comGhz with the same settings as VasVas 1st original post when he O.C@3.66ghz:
Memory Multiplyer: x8 (for 1333 RAM), x6 (for 1066 RAM)
Spread SPectrume: ON or OFF works fine
Currently I'm running the Prime95 for 5hrs now while web surfing and occasional gaming.
When I checked my Cpu temperatures this is what it reads.
These are all the current readings I have at 3.67ghz
I will try to Ofirstname.lastname@example.org when I am sure first that this is stable then maybe tomorrow I'll go with 4.0ghz
Oh and if you think this temperature is to high for 3.67ghz by all means let me know what I should do to lower the heat.
Thanks Again & CHEERS!
