i7 930 overclocking thread

[NewbieD]

yep, but it's a new toy so I think I'm gonna keep it like that for now...cool and stable ... I just saw another guy in this forum with my same batch using 1.18v...looks like this batch works fine with low voltages.

Could you post a link to your CPU-Z?

 

[SonDa5]

Working on solid 4ghz with low voltage. I have come down quite a ways and right now I'm at 4GHZ with 1.232v

21x192 multiplier

DDR3@ 2:8 7-7-7-21 1.53v

Pleased with this. I'll keep going lower on the voltage.

That was my low voltage stable 4GHZ with tight DDR3 timing 24/7 settings. This is being used in a case. 4GHZ stable is nice. I will be working on stable and fast.


I'm limited by my cooling. If I had a crazy liquid nitrogen cooling set up I'd be working on 5.5 GHZ .

Thanks OP, lotta work for you. Also, I've highlighted some important info that I feel would be helpful to know. Specifically room temperature and case cooling allows for a more accurate comparison for temps. Here's my stuffs...

I've about had it up to here w/ the RAM, so it's going back for some F3-12800CL7T-6GBPI's. The board is OK, but I'm having some S3 issues and it's butt ugly appearance is unsettling. I may just swap that out w/ the Sabertooth while I'm at it. The Asus Maximus I had in here before never batted an eye @ S3. I could sleep in the middle of Crysis and Prime95 and resume wo/ issue. The Giga likes to wake up randomly during the middle of the night.

So is 1.248 V for 4.0 alright? How bout the temps? Those seem wack to me, but it may be the retard mount w/ zero clearance above the capacitors. Even fully screwed down, the backplate is clearly uneven. I think a Venomous may be in the cards later, if for no other reason than to have a good mounting system.

EDIT:

DDR3@ 2:8 7-7-7-21 1.53v

Gah! That must be nice.

EDIT2:

Default ViD is 1.275v.

How do you know this?

 

[Zoson]

How do you know this?

Set bclk to 133 and vcore to auto. Set mem to 1066 with 10-10-10-27 timings. Booted and looked at the vcore with my multimeter.

My chip that does 4.2 comes up on auto at 1.2125v, this other chip that sucked and only did 3.8 came up at 1.275v.

You can't read i7 VID by software.

 

[Jodiuh]

Thank you.

With all settings defaulted like that, C1E, EIST, Turbo, HTT on, I get 1.216 V in CPU-Z w/ /LinX. So I'm good?

EDIT: Hmmm...once LinX starts to really hammer the CPU, it's actually 1.152 V. Woot!

What you're seeing is vdroop. turn LLC on to full/100%/level2.

You'll want LLC for overclocking anyway.

 

[Jodiuh]

More like 2nd level droop, it started @ 1.22something, then hit 1.216 for the 1st 30 sec ~ minute, and then hung around 1.152 for the rest of the run. I must have seen 10 different voltages between full idle and full load.

Is that what the dynamic voltage setting in the Gigabyte's BIOS can do? That would be very nice.

Do you think a Corsair H70 would help your build out?

 

[Zoson]

Nah.
I have two BlackIce GTX 120's and a single BlackIce GT Stealth 120.
They cool my cpu, motherboard, and both of the cores of my GTX275's. Memory and Power for my GPU's are cooled via Unisink. So I've got way more cooling than an H70, but way more to cool with it, also.

The fans I have on my rads only spin up to ~1650rpm at full speed. Nice and quiet rig, even at full load. Linpack is the only thing that can make my cpu get above 90... 4-5 hour sessions of TF2 only brought me up to 77C, and that's with my gpu's being run also. Prime will top me out at about 88.

I am probably going to do some heavy modding to my case so that I can fit in more radiators soon.

 

[Fir3hawk]

Good info about the voltages. I'm hoping to dive into a light overclock on my i7 930 pretty soon. I got the board setup last week and setup my Raid 5 this weekend.

Won't be overclocking much as I'm still on the intel heatsink and I think I'm stretching the limits of my PSU (750W OCZ w/ 4 HDDS, DVD/RW, i7, 6GB, GTX275, and a fair amount of case fans)

Your volts are very high for 4.2GHz. Should be between 1.28-1.32v for a good batch of CPUs.
I guess your batch is not that great if you need 1.36v. 96C is crazy high, you really want to max out at 85C. A custom WC loop should be 65C or lower.

With an H50, I got 4.2Ghz @ 1.28v - 81C. With the Mega I lowered my temps to 77C max.

Yeah, batch isn't very good. I got two chips. This was the better of the two. The other one needed 1.35v to even do 3.8GHz.

I think the real problem is I need 1.48v QPI to run my 12GB mem at 2GHz.

First time overclocking a CPU seriously, used the guide @ TechReaction
I had issues getting the BCLK to 200 with the [email protected] so I dropped it to [email protected] and it has worked fine
so far. Didnt play around with trying for lower ram voltages or timings and have not tried for lower volts on the cpu (just set to 1.2 to be safe when i started).

Not sure if i should try the QPI @ 1.38V+ to try for 200 BCLK, or turn HT on.

Up the CPU voltage to 1.3 and try again maybe?

 

[[H]ocusPocus]

Up the CPU voltage to 1.3 and try again maybe?

Agreed. Watch your temps, but you can possibly take the cpu up to 1.4v if needed with that cooling setup.

I'd also suggest trying to lower your QPI voltage for your current overclock now that you have something reasonable stable as it seems a biton the high side to me.

 

[Imaulle]

what voltage would be safe with my i7-930 and the corsair H70 ? right now I have 1.3v and under max load I hit about 62c max

 

[ThumperSD]

Keep it under 1.35v for daily use and you'll be fine

 

[SonDa5]

Very nice temps with that voltage.

What are your clocks?

Any photos of your set up?

Was stable at 19x200bclk at same QPI but down at 1.3v for CPU with lower max temp (mid 70s). Had to go to 1.35v CPU to get stable at 4.0 (20x200). I'm not very happy with the temps, although they don't get anyway near 80 during regular use. Maybe with a better fan on the TRUE I'd do better. With this much voltage needed just for 4.0GHz, I'd say that my batch isn't a preferred one.

Very much a work in progress. My first attempt and I thought I'd go for 200MHz bClk, 4GHz with RAM at rated speed (mem multiplier at 8x) and UnCore at 2x mem multiplier (16x). I tried these settings with all voltages at auto but it wouldn't POST. Set CPU Core to 1.3000v and launched right into Win7 and tested temps with Prime, they looked ok, so I ran the 20x LinX test. So far so good.

I have that same board....love it! Nice working hitting 4ghz right out of the gate. I wish this thread included QPI/VTT voltage. May I ask what yours is set at?

Nice job overclocking your i7s. I haven't tried to OC my 920 yet but it will come in due time.

I wish i had a D0 sometimes.

Well, I'm not stable yet. For that test all voltages were at auto except vcore which was a 1.3. It was quick run, just a quick That test was done with a small amount of memory, once I maxed the memory, LinX errored on the 4th run. I'm pretty sure I've got the headroom to hit 4ghz stable as I can get through 2 or 3 runs of LinX at 4.2GHz but temps begin hitting the 80c mark. I'm not sure if my issue is memory, voltage, or both. I haven't had time to work through it.

UPDATE: I updated my OC entry. At 4.0GHz stable now, but had to go to 1.35v CPU. QPI/VTT is at 1.235v with 200MHz bclk. Load temps touch the low 80s (like 82) under long stress tests (overnight runs of OCCT linpack).

The chips in these two boxes are i7 950's, not 930's.
The H50 is good for 3.8GHz without overheating in my opinion, and the H70 is good for 4.0GHz.

H50 with i7 950 at 3.8GHz on 1.3v = 90C max load.
H70 with i7 950 at 4.0GHz on 1.2875v = 88C max load.

My i950 will hit 200x20 at 1.25 volts with a max temp of 70 degrees at full load, something sounds off with your H70.

I am using a NH D14.

Heebs, with HT on or off?

On.

 

[Zoson]

On.

Is that Linpack tested? If not... You haven't found your max temp. You've gotta leave it going with the case closed for awhile... I'm talking 10+ hours LinX stable.

Nothing can heat your system up like a Linpack based stress tool.

Ive run it with OCCT and Prime 95 for several hours. Havent used Linpack yet to test it.

Anyone got a batch similar to mine:

FPO/Batch # 3018A651

I haven't opened the box and I have the opportunity to return it and get the i7 950, but I'm wondering if anyone knows whether this would be a good oc'er.

I'm bumping this thread with my latest OC to keep it around for people who may want to see more numbers on the 930 and/or the GA-X58A-UD3R

This is as far as I can take the chip. I over 191 BCLK @ 21x I can't keep it stable even throwing gobs of extra voltage on everything. Testing with the multiplier down low, I had no stability issues at 200BCLK, but the chip won't let me have anything over 191MHz x 21.

Load temps are a bit high, but my H70 should be arriving today, hopefully I can get temps down under 75°C or so and call it a stable 24/7 OC.

I clocked this chip to 3560MHz on it's second boot, changing nothing but BCLK. It ran that way for months and months. 3.8 takes a little bump in VTT, and 3.8-4.0 takes absurd voltage bumps to get stable. Oh well, guess I'll have to start saving my pennies for Sandy Bridge. Oh wait, I'm already saving the pennies for more GPU. Of course that has to wait until I can get a new SSD.

Does the [H] ever get tiring to you guys?
