Starting to see a lot of new users with i930s. Can you help out by posting your overclocking results with Batch Numbers here. The profile data can be pulled off your CPU label or Box Label and running CPU-Z. Please try to be as complete as possible. For temperatures I'm using Real Temp. Run 20 runs of Linx and use the max temp for a single core and the average of the four cores for the min. It's ok to submit partial profiles and WIP OC's but please update them when you have your final OC.

BADFASTBUSA: "3001A187's are incredible overclocking chips, if you can find one, get one... I have had and tested over 20 930's and out of them, the 135's were the worst and the 187's hands down were the best, all the others fell somewhere in between (STAY WAY AWAY FROM THE 135's THOUGH). My current 187 chip has seen 4.8ghz so far on water, and on chilled water, phase, dice, or L2N, theres no telling what this thing would do, but I may have it sold tomorrow though depending on if the gentlemen comes up with the money."

i7 930 OC'ing FAQ and other useful links
This section contains helpful tips & tricks. Use them at your own risk. I will not be held responsible for any damage caused to your CPU or system.

i7 Overclocking Guides (for those like me who are/were new to i7 OC'ing:

i7 930 Stock Voltages
Do your own due diligence when changing your voltages, this information is provide as is. I am not responsible if you fry your CPU.
  • Important: For i7 overclocking you need lock down at least Vcore, Vqpi and Vdram when OC'ing, using the auto setting for these voltages causes them to change dynamically and will impact your OC negatively. To avoid problems lock them down. Then you can try auto again once you have a stable OC.
  • Vcore = 1.2V (max 1.375V), Vqpi = 1.1V, Vdram = 1.5V (max 1.65V), Vpll = 1.8V
  • Vcore increases impact temperatures as well as stability. Higher voltages mean higher temps with Vcore impacting temps the most. With i7 Vqpi and Vdram also impact CPU temps (any function that is part of the CPU). Your constantly trading off between stability and keeping your temps low enough.
  • Think of increasing voltages as over stretching a rubber band. You do it to get more power, but the more you stretch it the more the long term life is impacted. If you go over a certain point it will break independent of it being a new rubber band or an older one. 1.35V is fairly safe with non-stock Air. Don't go over 1.4V on Air. See Cecil's guide for more recommendations in context of your OC'ing goals.
Temperatures
  • Temps are a function of the amount of voltage you use and the amount of circuitry running. Higher voltages = higher temps, more circuitry (see HT on/off) means higher temps. The voltage to temp ratio is not linear, the closer to the limit the higher the temp jumps. In difference to Core2 i7 has more functions (built in DRAM controller, QPI bridge, etc), so more voltages than just Vcore impact temps. The key ones are Vcore, Vqpi, Vdram. The biggest impact is Vcore still.
  • Over temp monitoring in the BIOS protects you, but if your pushing for the max (and know what you are doing) you might need to turn this off.
  • First download Realtemp and Linx.
  • I measure my load temp by running Realtemp and Linx (20 runs). Take the max of all 4 cores (Realtemp tracks this for the whole run, remember to reset before starting).
  • For the min temp, run the sensor test (uses Prime95 - lower than your typical idle) and take the average of the four cores.
  • As a rule of thumb <83c load in Linx (20 runs) is ok. Then run Prime95 for 8+ hours and see if your temps go up more (ambient temp issue if they do).
  • Some people prefer <80c for long term, but they typically are also ok with lower OC's <=4GHz. Hard to get <80c temps when using Air cooling and >=4.2GHz.

RAM rated speed: 1333 MHz
RAM actual speed: 1125 MHz
RAM Latency: 8-8-8-19 1T
RAM Voltage: 1.6V

3/22: Bumped up Vcore to 1.344. Temps are still below 83c. Hit 4001 MHz. Able to run 20 passes of LinX.

3/21: Turned HT on and started to run into heat and stability issues. My case is small (LianLi PCA05B) so my ambient temps are high. I ended up re-seating my heatsink and reapplying TIM. I also redid the fans near the CPU to vent air. Both helped with the temps and I've gotten the PC stable to 3801 MHz with lower voltages. I was able to do 20 runs of LinX with a maximum temperature of 76c. Voltages are now Vcore 1.3, Vdimm 1.6, Vqpi 1.3, Vppl 1.8. 4GHz is giving me a major headache, still working on it.

3/16: Hit 4.0 today after changing Vcore to 1.3V and Vqpi to 1.2V. TEmps are 50c idle and 77c load. Cores 2 and 4 in Real temp tend to be 4-5C hotter than 1 and 3. I might try reseating my heatsink. Hit 4.2GHz using softfsb but it would lock once I tried running prime. Starting a stability run using LinX at 4GHz. Changed mem timings to 8-8-8-24 to avoid any problems at close to 1333MHz

3/15: Swapped out the Intel cooler with a Cogage True Spirit. Temps dropped to 69c at load and 47c idle. I was able to boost my OC to 3.79GHz (21x180.6). I'm still running on stock 1.2 Vcore, 1.1 Vqpi.

3/14: As suspected being a Noobie at OC'ing i7's I did a couple of stupid things. I went ahead and set Vcore to stock 1.2 (1.216V in CPU-Z) amd Vqpi to 1.1. Turned of EIST, Speedstep, C1E. Running DDR3 at 900MHz and QPI at 2.7GT/s. Temps dropped down to 50c idle and 79c max load. Next step is to see if I can get a higher Core Speed. BTW, the previous speed was wrong, it should have been 3.163GHz with the 3.3GHz being turbo boost (150x22). Using the above settings I broke through 160Blck and I'm now running at 3.56GHz (21x170Blck). Crashed setfsb at around 178 Blck. Temps are around 52c Idle and 83c load.

3/14: Still a work in progress. Initial OC was to check what the stock cooling would support. Tends to crach at 160+ Bclk. I have a Cogage True Spirit that I will be installing next. Temp (Idle / Load): 54C / 90C with Vcore/Core Voltage: 1.376V.

O wow that seems not so good.
@ 1.376V and 3.3? 90C YIKESS!!!
Hmmm someone said it goes to 4.0 @ stock cooler, thats out i guess.
Well will wait for more :)

people really do need to use:
http://cpuoverclockers.com/
it covers all relevant information in a spread sheet form and you can search it.

tell your friends.

I'll add it to the links section, but that site doesn't have any i7 930s. I use HardForum the most so I thought collecting the different threads for i7 930 in one place would be nice. If no one posts their configs I guess no one else thinks this is useful.

Here are a couple of threads:
- http://www.overclock.net/intel-cpus/587201-intel-core-i7-series-batch-guide.html
- i7 930 batch thread: http://www.overclock.net/intel-cpus/684156-i7-930-batch-numbers-3.html

It's still a work in progress and I'm pretty much using default settings on my MB. I didn't push it higher because of the temps and it starts crashing around 160+ BClk anyway. Haven't seen that about doing 4GHz on a stock cooler (saw that on the hexacore 32nm i7 hit 4.1GHz on stock Intel cooling.).

the stock Intel heat sink / fan that comes with the 6 core is a beast compared to the one that came with your i7 930

I didn't see the hexa-core stock heatsink in the anandtech article I read. I guess I was expecting more of the same vertical blower design. The new tower design with 4 heat pipes looks more like my Cogage True Spirit and should cool more efficiently.

Still the stock i7 930 wasn't too bad. After my locking down my voltages to the real stock levels (1.2 and 1.1) I was getting much better temps and OC's. I got 3.56GHz (21x170Blck) before crashing at around 178 Bclk. Temps were down to 52c Idle and 83c.

After ditching the stock cooler for the Cogage True Spirit my temps are in the 10-15C lower at 3.56GHz. I introduced some kind of instability because my box wouldn't boot without some major coaxing. I had to reset the bios and slowly work my way up again, but despite the cooler temperatures the PC crashes quicker right after passing 170 Blck mark.

For those interested the new Cogage True Spirit 1366 bolt retention is very snug. No need for the washer mod that folks use when using a TR retention kit. Once screwed down tightly I can't move the heatsink.

here's a SS of out my setup. ran p95 for 20 minutes to get load temps settled. didn't see it get any higher then 70c on the hottest core.

Nice!!! Did you change any of your other voltages? I haven't tried turning turbo boost off. BTW, try out realtem. It uses Prime95 to heat-up the CPU and tracks highest temperature and lowest ones. Make the process more repeatable.

I passed 20 runs of Linx and now I'm running Prime95 overnight. 75m so far and I'm watching HDTV in parallel. So far so good.

what is the highest I can overclock without changing voltages?

Not sure how much experience you have with i7 overclocking, but that will depend on your motherboard and cooling. When using auto settings the voltages are actually changed to match your overclock. 1st step in OC'ing is to turn off any voltage compensation and manually set your voltages to stock or your comfort level for Vcore (1.2V), Vqpi (1.1V) and Vdimm (1.5). See my OC progress under my entry here. I went from 1.376 Vcore with auto Vcore and 3.3GHz OC to 3.56GHz after locking down the Voltages to stock levels. In both cases I was using the stock cooler and a hot (~30c ambient) small LianLi PCA05B case.

This article was recommended to me and provides a good overview of i7 OC'ing. I have quite a bit of OC'ing experience, but i7 brought along a lot of variables that effect OC'ing that I had to get familiar with.

Can you post your BCLK speeds as well

Bclk is implied by dividing the CPU frequency by the multiplier. Both are in listed in completed entries.

Yeah but that would involve me calculating that myself, why don't you just write it down, im lazy.

i tried a little to get 21x200 working but my processor didn't want anything to do with it. 4Ghz will just have to do :).

The 21 multi is the best these can use, so its better to just stick with the 920 since they are cheaper. The 22x multi on these is useless for high OCs.

I will have mine posted this weekend...putting together my 3001A124, just waiting on memory to come in. One review on NewEgg with this core hit 4.5 on air...if that's an indicator.

I'm currently trying to decide between 920 and 930:confused:

multiplier aside, does the 930 chip have any other improvement or tend to overclock better?

BTW, whats wrong with the 930's x22 multiplier

Thanks;)

Will I see a big jump going from a q6600 to an i7 930? My q6600 is running at 3.4ghz and I have an ati 5870. I run everything on high right now, just wondering if there would be a noticable difference for the cpu upgrade.... I also play BC2 which is core dependant

920 is cheaper, and they are both the same thing aside from multi. There is no improvement, and even multis are less stable at higher clocks then odd multis. Save the money and get the 920.

Of course with that logic, any higher line CPU would be a waste of money. (just saying, not saying that's right)

Now just what bright genious made the determination even multipliers are less stable than odd multipliers?

Besides, you can't be so quick to make judgement, the 930 has already hit 4.5 on air, so you really need a larger sample of 930 users to determine if it's better or not on whole. Now throw in the fact 930's cost as low as $229 (what I paid for mine) the price argument is disputable as well.

It depends on how far you OC your i7 930. See the link below for a comparison between a 3.33GHz i7-975 and a 3GHz QX6850. That is roughtly in the ball park of what your asking. In gaming it is about 30% increase. If you get a 920 or 930 you should be able to hit 4GHz.

Given your system you could hang on a bit longer till the prices of the hexa-core drop. If you have a Fry's or MC nearby you can get good combo deals which make waiting a bit harder since they often sell the CPU at the $200-250 mark.

I'm of the same mind as you. Looking for a nice stable OC, then I'll boost it up close to the max with SetFSB when I game or need the additional processing power.

I'm envious of the 4.4OC. I just bought 4 Coolermaster 120mm 110cfm fans at $5 a piece for my case (LianLi PCA05B) in an attempt to get my ambient case temperature down from 40c. Hope they are not too loud.

Eh, I got lucky in the chip, but unlucky the memory. I got a chip that very, very cool, and ram that runs very, very hot. You know how the cpu lottery goes. I'd bet someone who's more of a risk taker then me could probably have pushed the chip up the 4.6 or 4.8 (I have room thermally, but I hate to push the voltage past the recommended limits).

I just updated my system to a core i7 930, currently @ 3.8ghz.
I was using a Q6600 @ 3.2ghz.

My BC2 FPS went from the 70 range to the 100-110 range.

So is it necessary? Probably not, but it is nice? Oh yes.

Look around, and you will see even multis suck with i7s. 920s hit 4.5 air all the time with HT off. There is no way he did with it on unless it was just for a validation. My 920 can pass 20x Linx stable with HT on at 4.5Ghz under water. I can bench at 4.7-4.8. The 930's 22x multi stops around 4.2 or so, making only the 21x multi usable at high speeds. I know many extreme overclockers that bought 930s to toy with, and sold them the next day since they are not as good as early 920s.

The 930s will clock the same as the newer 920s, but not nearly as good as the older ones. The 920 is $30 less, so no point in spending the $30 on the same chip.

I have a Frys and MC here, I actually have 2 Frys and 2 MC local, gotta love Atlanta

Yea the deals are killing me, im itching to upgrade I just dont see the necessity. The only reason I want to upgrade is so I can use 2xq6600's for 2 virtual esx machines for a lab I plan on building, 1 of the q6600's im currently using so i would have to upgrade to use the other. Another option I have is, I have an E6750 and a E6600 laying around, do you think of I OC an E6750 it would be comparable to a Q6600 to get me by for now? I hear you can do 4ghz on E6750

Is there any benefit of running HT off just for a few extra MHz? Seems like if it can't do it enabled, then you shouldn't be pushing it that high. Then again, I really don;t know how much benefit HT really gives you. (Can't wait to get this up and running...freaking newegg shipping has gone to hell lately).

the 930 i worked on clocking was VERY thirsty and needed water to clock at 1.45v@ 4.3ghz

About a 20-30% increase in multi-threaded apps. I never turn it off, except for benching since its easier to hit higher speeds with it off (it drops temps 10-12C turning it off).

Sounds like a C0/C1 or just a bad batch.
