almost 8 hours of prime 95
Batch 3001A179
yes, a nice chip 3001A179:up:
wow does any 930 fpo/batch become new golden batch yet???
like 920 golden with below 1.4 VCore @ 4.5Ghz prime stable
Hello all, thanks for screen's and informative posts!
I have a new 17 930 (forgot to look at batch sorry!)
I want to run it daily at 4.0ghz, it is under a fuzion
waterblock. I only have rubbish XMS3 RAM, and a P6T,
I was just wondering what people think is a safe temperature
to reach while under prime (knowing in real life it will never get
that hot) and what are safe voltages for CPU and QPI.
Also can someone please explain uncore speed, I am not
looking to have it super fast until I get better RAM, just stable
at 4ghz.
Any help would be appreciated, thanks.

Vcore at 1.2625 in BIOS, QPI at 1.225, mem 1.64. All other auto. Also done 20 runs on this settings.
I think this is pretty bad chip-temps are way too high with my Venomous X+1 Scytche Slip Stream at 2000 rpm in pull :(
Room temps are 24-25.
i have batch #3951A690 4hhz@1.216v and 4.2ghz@1.280v
Thanks for screens, nice work!
Hi. I have also joined i7 930 club:)My batch is #3951A694 and my first hours on this cpu are great. At this moment it can run at 4200 and 1.33v but as i sad its my first day with this cpu so if anyone have any sugestion about voltages etc. plz advice me:)

How about temps? arent they too hot? I have Watercool CPU block(the best one) and 2 radiators first have 6fans and second have 4! meaby mounting cpu block is not good?
My latest OC at 4.2ghz fully stable with HT on....i reckon i could take this chip to atleast 4.3 with HT on maybe even higher.With HT off i reckon i could go 4.5+
Prime 95....8 hours
http://i51.photobucket.com/albums/f3...stable9hrs.png
Linx 20 passes
http://i51.photobucket.com/albums/f3...ssmem24000.png
IntelBurn test 50 passes
http://i51.photobucket.com/albums/f3...50passes-1.png
Occt(Linpack) 2 hours
http://i51.photobucket.com/albums/f3...ct2hrs42-1.png
Next im going to push for 4.3 possibly higher,then ill try and see with HT off.
Guess that i have made something wrong when mouted a CPU block after looking at your ilde temps. My are 38-39-37-38 and when linx is on my load are 74-73-70-71. Should i check cpu block again?Quote:

it may not be your block it may be that you have too much voltage going through,try going down a volt at a time on the vcoreQuote:

Cpu at 1.34v
QPI at 1.38v
Dram at 1.64v
Ram is hardly overclocked, 763mhz at 9-9-9-27 2t.
P6t Motherboard.
I don't think you need to set your QPI volts so high to achieve 4GHz with an i7 930 The0men. Try to lower it a bit.
Also what multiplier are you using right now? If you are using 22x try to use the 21x multiplier and rise your BCLK.
My 930 doesn't seem to like the 22x multiplier a lot so when i use 21x i need less CPU volts to be stable.
Yer, I am using 21x Multiplier. Seems stable now, just hot, I will lower QPI and CPU voltage.
I am thinking it might be that my RAM is well and truly the weakest link, I guess I will
have to invest in some better RAM, this cheap XMS just doesn't cut it.
I will lower some voltages, leave RAM as it is and see how goes when I get some time.
Thanks for the advice.
My 930 is one of the 'good' batches apparently - 3912C699.
4Ghz @ 191x21 @ 1.24 (cpu-z load)
HT ON
Idle: 41 39 42 38
Load: 73 72 72 68 <---first core always hottest
Ambient ~20-22'C
4.2Ghz @ 200x21 @ 1.28 (cpu-z load)
HT OFF
Temps: I didn't write them down but pretty similar to above. Main thing is I had to turn the HT OFF to keep things at my target max temp of under 73'C.
Load temps are using IBT. I note Prime95 is about 2-3'C LESS. IBT is run in standard win with most of my apps turned off.
Other settings are constant:
- QPI/VTT 1.2
- PLL 1.8, IOH 1.2, ICH 1.1
- DRAM 1.66 @ stock speeds 9-9-9-27
- mem 1541, uncore to 3082, QPI link lowest setting
- LLC ON, Energy saving off, Turbo off, Spread off
I have managed to run 60 runs of IBT for my 4Ghz setting. 4.2Ghz has done about 18 runs but I find that if it passes 10 then I'm usually good.
Would Upgrading a E8500@ 4.2ghz to a i7 930 @ 4 ghz on H20 be upgrade that will be worth it, for speed and price wise?
Depends on so many things:Quote:

I game, I currently have a 4850 512 mb I want to get a 480 and water cool with the rest of my rig
But I only have a 650 PS? Might go with a 5870 but driver issues makes me not want to.
High FPS would be nice,
I have a 24 inch Monitor 1920
I just wanted to know if a OC E8500 to a I7 would be night and day difference?
I would say you would barely notice the difference in real world scenarios with your current card. A GTX480 or HD5870 would definitely see some increases in CPU heavy games, such as GTA IV, Dragon Age, BF:BC2, etc. Because they are heavily optimized for quad cores. By the way, what driver issues for the HD5870 are you talking about?:confused:
Simply by enabling Load line Calibration I am able to drastically drop all of my voltages,
even beyond the low point when I was stress testing and CPU voltage dropped.
Not sure why this is so, I mean, if I was able to drop a little bit I would understand,
but not by this much, makes no sense.
CPU 1.32
QPI 1.32
DRAM 1.62
Anyway, I am happy, now runs cooler, less voltage to everything, and stable at 4ghz :)
Hi Guys
SomeOne Told Me Core i7 930 Multiplyer Locked In 21X ? And With Turbo=22
And When Active Just One Core Rich 23X Multi???? Is That True?
Pardon my ignorance, (amd user here) is LLC a motherboard feature? or is it part of the intel i7 architecture?Quote:

thanks!
I believe it's a motherboard feature. I'm pretty sure all the decent boards have it in the bios. It's supposed to keep the volts constant or so at idle and at load. Instead of vdroop or vdrop. I'm no expert but I believe it's supposed to help with OC in those regards.Quote:

I may try it to see if my temps get lower.
LLC is a motherboard feature which is going against Intel specs. They state a certain amount of vdroop is needed for safeguard to not have voltage upward spikes after heavy load. I remember someone did some tests with an oscilloscope and for sure with LLC there were spikes well above 2v. With a tool with OCCT you don't even see them. Now even if those spikes are dangerous and could kill your chip on the spot there are way to many people on the net running their oc with LLC, for years without damage even under heavy loading like folding or wcg. So I guess Intels chip are pretty resilient against this kind of abuse. Only i7s I heard to die were the ones where the person running it didn't stay within .5v differential between vtt and dram voltage.
Just use it depending on what is more stable with your setup.
Thanks darkboss, sounds like an active voltage feature - to keep voltage to the cpu more or less constant - which I'm guessing would have to be motherboard based. After the troubles I've had with the over-volt feature on my current board, (would cold boot but would not survive a re-boot because of vdroop) it sounds like mana from heaven!
Thanks for the details p2501. My guess is that the spike - while taking it into a realm you wouldn't dream of running 24/7 - is limited to ahhh, let's guess at .2 or .3 volts, or something that's not going to immediately fry your chip. rather something near a level that people would run suicide shots at. it's probably a "feature" added to compensate for the voltage lag when the cpu goes from low to full that I'm guessing would be extremely difficult to predict.
best guess, the motherboard is trying to predict heavy loads from the processor and upping the voltage actively (before the processor hits 100% and drains the caps or whatever) instead of re-actively ( where it would wait until the caps start to drain before boosting the voltage, causing that brief *and dreaded* vdroop)
just a guess of course, but an interesting option... might explain why the0men was able to lower his voltage settings?
Yer, it is a motherboard feature as stated, it's something I've always previously tried to avoid using.
Thing is though, the voltage I use with LLC is so much lower that even when under full load the voltage
is still lower than under load with the vdroop. I still don't understand it.
With any luck it will make no difference how little I use the computer under intense load.
:):):):) Guys :confused:Quote:

for i7, yes. Mine is 24/7 right around 70c. Can handle pretty much up to 80/85 IMO.Quote:

When you have LLC off, then you need to 'up' your bios vCore so by the time it vdrops (between bios and idle) and vdroops (between idle and load) it gives your cpuz enough volt to be stable.
Most people recommend LLC ON but there's been 'reports' saying it's not a good idea. I think it's safe either way but where possible I have it off. No point chancing it right? I want this thing to last.
That is why when you have LLC ON you're getting less volts in the bios. I bet if you go back and turn off LLC off and observe your CPU-Z volt when loaded, it's the same as you have it now with LLC On. You just don't have to bump it up in the bios to eventually have it vdrop/vdroop to a lower level needed by your CPU.
Yes, I realise, however with LLC I can lower the voltage far beyond the droop or lowest voltage
reached when I have it off. That's the anomaly, not that it works or how it works.
On previous boards LLC has never behaved that way, I still always needed to keep the voltage at
Load roughly the same.
Maybe your chip then? On mine, for a stable 4Ghz OC, my load volt is the same regardless of LLC ON or OFF. I just had to bump the bios volt higher when LLC OFF.Quote:

I'll be v curious of your findings as I would love to drop my volts just because I have LLC ON. :D
I'll try and get some time, but as it is it is a hack over clock, I stuck it together, set it at 4ghz,
the first time it was stable I left it alone, can probably drop the voltage on a lot of things.
It's all about time at the moment. If I do get to knock off early or something one day and I can
get someone else to cook, I'll try tinker with the BIOS a little further.
i am searching lowest VCore batch of 930
I've been using this setup for the last couple hours to play some games. I'm thinking it's not stable though. :D

Still waiting for my RAM...G.Skill Ripjaws DDR3-2000 (3x2GB).
I recently got my RAM. 4ghz is easypie with my W3530. Will shoot for 4.3ghz-4.5ghz next. Doing quick stability checks every 100mhz with Hyperpi 32m. Once I reach a speed I'm happy with, I'll follow it up with some Linx, Prime Blend and OCCT till I'm 100% stable.
Sounds like a good plan. Made me think, I wonder if sometimes a chip needs to be "broken in" I'm getting much better overclocks now after a couple months of use than I did when the cpu was new. Could also be I'm just getting better at it.Quote:

New i7 930 3001A, last 3 digits I don't remember unfortunately but iirc they were 539. Cooling is Venomous X with 2 Scythe Slipstream 1600 rpm fans in push pull. I think temps are a bit high so I might have to reseat. Also ran out of MX-3 so I am using AS5 atm.
woah those temps are high, and there is no way you need 1.29v for 4GHz
Yeah I figured, I think it was 20x multi screwing me over. In the process of lowering vcore as we speak, 19x211 now.
Question:
This processor has problems with multi 22X?
Yeah, for high overclocks, you should even odd multipliers, because i7 seems to hate even multipliers. This is true for any i7 chip though, not just the 930.Quote:

Great little i7 trick! :up: 4.2ghz is currently stable, but aiming for lower vCore now (using 1.344 at the moment).
Hmm I am thinking I am doing something wrong with the Venomous X, idle temps 45c max, hit 77c Priming for 30 mins. Are my fans too weak? I am only running 1.25v BIOS 1.26v real core voltage now... 211x19, it seems stable but runs really, really hot. Batch # was 3001A531 btw.
EDIT: Did another reseat of the Venomous, it no longer wiggles and temps dropped a bit. Hit 75c max with 1.256 vcore after 40 mins of priming.
hey guys i wanted to ask i've got a 3002a717 batch from a top seller on ebay, he said he did 4.4ghz wit 1.43 ac with a ven x and 77 load temps. i'm kinda scared he might have sent me the wrong cpu by misstake, i was planning on a extreme rog 3 and i have a monster of an lcs setup... what do you guys think. i was hoping on pushing my boundies of 4.5ghz stable (with an e8400) since ive got a huge lcs ect. but after reading up on the batch, i feel like ive had anoter streak of bad luck... i was just really hoping on a good batch, since i havnt had god luck with my last two :'( and cant afford new cpus all the time
ps. seems like today is just the mother of bad days for me =(
It's the same chip, but renaming it and calling it something new gives it more of a shelf life. The 930 is something of a transitional thing, between yesterday's news, until tomorrow morning. Think of it as The Afternoon Edition! :)
this is nothing unusual, people used to do it all the time a few years ago, then once C2D came out it seemed like people stopped, i kept hearing that undervolting no longer helped.Quote:

Batch #3002A582 / 3/2/2010
MICROCENTER- Santa Clara, CA 199.00
I am doing some testing trying to get the lowest volts for a 24/7 set @ 4.2GHz. I am testing 3 passes Linx full (MiB) Cores 1 and 2 run 6- 7C higher than the and 2 and 4. During full load they differ only 2- 3C difference. Idle temps mean little from what I have read. I have notices screen shots of people with lower idles but with higher full load load temps.
Have a look see, thanks!

At that speed you should be able to lower your cpu voltages under 1.3, that should help with temps.Quote:

75C (under Prime95 small FFT) acceptable temp for a 24/7 OC? Normal use will never get to those temps.
Just use LinX, it's much faster than Prime and just as stressing. 50-passes should be more than enough.
Chewie_77 can you post your settings please? i can't pass linX, second pass and error
@Kimofil: i'm using a Noctua NH-D14 powered gently by Noctua.
Here is another SS, this week i will try with XP.

Damn its been a while since someone has posted in this thread...but have the 930s improved lately regarding overclockability?
Seems the best ones I have seen typically do 4ghz 1.17-1.18v HT on Linx stable? Is this still the case?
i7 930 batch #3002A648 not to bad. can run @4.2 1.28 volts..and 4.3 with 1.328 volts.:)
Got an medicore one 1.312 V under load 4 GHz , if I push it to 4.2 unstable
And even without HT. 4 GHz HT requires 1.33V Load .. not worth mentioning
I bought a 930 to play with. I will see how it oc. I will try a 4ghz oc to get an initial impression. Batch# 3018A120
Quick and dirty linx run:

Seems like a pretty nice chip! What kind of cooling? How much vtt? I would like to see how the chip scales... 21x200? or perhaps even 21x210?Quote:

I doubt it will match my 950 3847A but a nice surprise for a 930. I did briefly try 210x21, again loose volts just to get a feeler - vcore ~1.33v 7 loop linx, stopped then tried 4ghz
hey mate, try 1.3cpu pll and 1.38-1.4 qpi/vtt for 4.2Quote:

I have recently got my hands on two medium new 920s and they both sucked. Also tried one month old 930 which was just as bad.
Yesterday bought one a little older batch 930 but didnt have much luck with this either. Its a 3938B which is quite a promising number for 920s but apperantly wasnt so good for 930.
It does 4ghz with 1.3v set on bios and 4.4ghz with 1.475v set on bios. Both with HT on. Im using powerchips gskill ripjaws and X58A-UD7. The rig is highly touchy about any voltages and has huge learning curve. Im still figuring out whats the problem. Memory sticks work well only on default speed (1600mhz 7-8-7-24) and dont like any ohter. Not lower, not higher. :(
Anyway. I already ordered 980x which i get in monday. Im sick of my i7 bad luck and decided to go gulftown instead. :up:
That is interesting regarding your 930 batch #3938Bxxx... I'm curious to know what the rest of the batch# is for your chip? I had a 920 #3938B010 that was a very nice clocker.Quote:

4.2ghz HT on stable at 1.35v. Not too bad. Not brilliant either.
As i said. 920 with this batch is awesome. 930 seems not so awesome...
op is back! lol i should get back into this stuff... try and hit 4.4 with my h50 on a 24/7 OC.
My cpu is 4.3 at 1.38v
qpi is 1.41v fully stable in linx,occt,ibt and prime 95.
