Very, very pleased with my chip. Going to try and push it up to 4.2Ghz on air. The Prolimatech's taken my load temps down by 10C vs a lapped Tuniq Tower Extreme!

PS: My core1 temperature's always consistently higher than the other cores and it's (1) pissing me off and (2) limiting my overclock. Will lapping help?
 
i'm on a 920 but i've found with my chip

I can do up to 3.6 at stock vcore but to hit 3.8 I need 1.25v. I haven't pushed for 4Ghz yet

at 3.6 i'm looking at these idle temps 40/37/40/37 Full load 69/67/66/65

at 3.8 all temps go up 2-3c.

Push/pull config is also not at 100% only about 50% on a fan controller when I took the temps.

Been reading alot of the post think I should be able to push further with some of the settings i've seen.

Hi guys,

Normally I wouldn't have written,but Im goin nuts, I have i7 930, x58a ud3r, BIOS version FB and I can't get my rig stable.

I have tried everything to get it stable, dozens of guides, copied templates from guys that have same components as I do, every multiplier, every setting, every BIOS version from FB to FE, vcore range from 1.175-1.32, every combination really and its still unstable and gives me BSODs or random crashes.
Now my question is: Yesterday I opened the rig to check RAM timings and its nothing on it, when I bought it, the site stated that it has corsair ddr 3, 1333 rams and the only thing marked on the modules is KINGMOS which I don't know about so it must be a fake or an unbranded peace of junk. Could it be the one causing the instability? Do I need to buy new rams with higher frequency? I'm trying to hit a stable 3.8 or 4 ghz.

Can anyone help me? :)

Use CPU-Z to view memory timings. I think it is a memory frequency/timings problem. You're memory aren't capable of high frequencies, so you should make sure to set a high multiplier (x21) in order to get low memory frequencies. I haven't heard of that memory brand before, so maybe you just have some bad memories which can't tolorate too much touching :). Anyways,

Try out with these settings:

Vcore: 1.35 V
QPI voltage: 1.3 V
Pll voltage: 1.86 V
Memory voltage: 1.65 V
Memory timings: 9-9-9-24 (make sure to use high timings in order to have overclocked memory frequency)
BCLK: 181 MHz (21x181 MHz = 3800 MHz core frequency)
FSB:DRAM 2:8 (memory frequency = FSB*(FSB:DRAM)*2 = 181 MHz*4*2 = 1448 MHz) If you have a good set of memory they should be able to reach it.
Also, make sure to disable all OC-helping settings in BIOS.

If you still get unstable system try to lower memory frequency.
 
Thanks for the reply,

I had enough of guessing and playing games for 5 min or rendering for 2 :D I ordered Apacer 6GB (3x2GB) 1600MHz Overclocking GIANT II DDR3 modules, and hope they will work.

I'll get back with the results :)

I'm posting here because I can't seem to get my voltages any lower than this without Prime95 failing. I know these voltages are high, even compared to someone with the same batch. Am I doing something wrong?

Edit: Stable on these settings, I just don't want it running on those voltages day-to-day.

May need to lower the core and increase the QPI/DRAM voltage.

Try a higher QPI/DRAM voltage at 1.375v
 
Turbo mode has been disabled.

(191x21)

Vcore 1.4 V
QPI 1.375 V

I'll try for a higher speed and lower voltages when I get home. Prime95 was stable with these when I left for class this morning, we'll see when I get back.

Brilliant :)

When using a high BCLK you will need to push the QPI/DRAM voltage up, i need 1.375 for over 200MHz ish BCLK.
 
Prime95 was still going when I got home. 191x21 works with 1.4 V Vcore and 1.375 V QPI. 200x21 will not work with the same settings, or with QPI at 1.4 V. I'm hoping to keep the vcore under 1.4 V. Any suggestions?

Edit: Could this be because it's trying to run my ram overclocked (barely) and I still have it on the stock voltage (1.65 V)?

On my i7 930 I needed 1.4875v QPI/DRAM to get 200BCLK stable.
At 21x200 I was using 1.36875v Core and 1.4875v QPI/DRAM.
You probably also need between 1.16v and 1.25v ICH for 200BCLK.

1.4875v?? that's pretty damn high.

I have 206MHz BCLK right now at stock ICH voltage and 1.375v on QPI/DRAM. It does differ from chip to chip and also motherboard but 1.4875v on QPI is a lot higher than normal for this sort of overclock.

Yes most probably, keep the RAM speed as close to their advertised speed, you can deal with memory later. I don't suggest going over 1.66v on the memory but as you've increased the QPI/DRAM voltage it's ok to go a little over but best keep it under 1.7v.

You shouldn't need more than 1.35v on the vcore to get passed the 4GHz mark but again, not every chip is the same.
 
Back off the ram overclock. With the onboard memory controller you don't need integer ratios with your ram. Also, 1.4V should be fine long term on the CPU. Furthermore, use Intel Burn Test instead of prime 95 for stability testing. If you must use prime95 then do it only as a final test.

I'm running 3x4GB sticks at 2GHz... Thus more QPI/DRAM. The game changes when you move from 1600MHz to 2GHz, and it changes again when you move from 6GB to 12GB memory.

I'm running 9Gb of RAM (6Gb kit + 3Gb Kit), didn't change anything when i moved from 3 sticks to 6.

QPI can go a lot faster. If you read on some forums, depending on what ram you have, Corsair, Patriot or even GSkill can recommend up to 1.6. I know lots of people say stay at 1.35, and that's what I did, and I could never shatter 4ghz. I finally followed their recommendations and pushed QPI. My VCore is still safe at 1.32, but dang... I had to push QPI to 1.5 or so to hit 4.1ghz.

I probably could have gone higher without turbo boost that occasionally put the first core up to 4370 and such, but I don't plan on running with so much noise for so little gain.
I put it back down to 160 MHz FSB and quiet fan settings and that's where I'll stay unless I get the occasional need for speed.
Right now max OC does me no good, since I still need to upgrade video cards (X1950XTX Crossfire for now).
I did notice the last 2 cores running about 4º colder than the first two, but maybe turbo boost was causing that.


Is your speed of 4.2GHZ based on the 1 core at 23 multiplier?
 
Hi Guys,

I just came across this forum and it looks pretty awesome.

I too, have a i7-930 and after reading this thread, I thought I would give it a push again.

Thanks to some of the advice here, I had mine running pretty stable at 4.5 Ghz yesterday (but was running pretty hot with my H50 cooler).

I have just put another fan on the radiator to make it more like a H70 to see if that makes a difference.

I'll let you know how it goes.

Your instability isn't due to the Corsair GT, you just need to give your CPU more voltage.

I have the same MB, Corsair Dominator 1600, and I run my VCore at 1.35V. Core i7 930 D0, Rampage III Formula MB.

The CPU is rock solid at 4.1 GHz and temps are 45C under full gaming load; watercooled by a HeatKiller and a 120.3 Swiftech radiator.

The only thing I touched in the BIOS was the VCore and the VDimm, everything else is on default or auto.

sorry dude, im 99% sure you're wrong. It wont even boot in XMP. Needed to jackup the qpi/vdimm (uncore voltage) to 1.35 to get it working at 1600mhz 9-9-9-24. I cannot for the life of me get it to 2000mhz, 9-10-9-27. XMP even sets the uncore to 1.25 - which tells me the intel specification isnt correct for 2000mhz ram.

Cpu voltage is just fine.

i should add, on my last mobo, it was stable at 1.108v vCore @ 3.6 ghz. Great chip. But right now im trying for 3.6 ghz on the cpu, and ~2000mhz on the ram, and it wont do it. I dont want to go over 3.6 ghz cuz then i have to put my h70 fans in fastmode, and thats annoying ;)

Understood.
I would assume the actual rating for those sticks of RAM is 1600, and OCd will reach 2000?

I dont know, my 1600 is in actuality a 1333 stick that will hit 1600 if i ask it really nice.
Currently my 1600 is running at 1550, which is just fine with me; that and I don't have to fuss with it, it just runs.
 
I run my 920 DO on this dfi board with auto volts on everything..ive set the bclk at 175 and set the ram to 1.52v at 1600 and this thing is just great...it eats up anything i do ..its an early 920 DO and the batch # escapes me at the moment...its probubly as energy efficiant as i7 can be...
I personally like the speed step option enabled...I had it at 4.0 when i first got it but for what i use it for i saw no real world benefit....
Alot of guys ask how to get highest o/clock with auto and s/step enabled..well this is how my dfi runs...
ive pinned out the voltages and they are spot on with bios settings...temps are great with a cobra cooler and active cooling on the n/bridge...38-39c idle and 75c with intel burn...
i control all the fans manually. im very happy with 1366...

well, corsair sold the ram as being rated at 2000mhz @ 9-10-9-27, so i was hoping to get it to height... i did pay out of my ass for these when i could have gotten some MUCH cheaper patriot viper modules. I dunno, there may be some secret rating convention that i don't understand with how the rate and test them.

So far its working fine at 1725 mhz @ 9-9-9-24. I'm going to bench it like this probably, and then bench it again at the higher freq and loosened timings to see if theres any advantage. :)

Just because the Ram will do 2000mhz, doesn't mean the IMC on the CPU will. You might not be giving it enough qpi/vtt.
 
I don't have a 930, but I do have a D0 920 and figured I'd share my results...

Mutli: 21
BCLK: 200
Vcore: 1.35v
QPI: 1.35v
Temps: 50C idle, 84C load
Stability: 30 runs IBT, 1 month of gaming with no issues.
All intel stock settings are enabled, HT on, etc

Still love my 1366...

by that you mean qpi voltage right?

The funny thing, the XMP profile - which is supposed to be tested and approved by intel - on the sticks sets them to 2000mhz, 9-10-9-27, and 1.25 v on the qpi.
I went into manual mode, and jacked the qpi voltage to 1.35, and it started booting. I'm quite happy with its performance now.

But in the future, do you just think that i'd need higher qpi voltage to run higher ram frequencies?

Thanks :)
 
Some people need to go up to 1.6v to stabilize in the 2000mhz ranges. There are actually sticks out there from Corsair that XMP sets your QPI to 1.6v.

I'd recommend gradually increasing until stable and use as low of a voltage as possible.

Also, I was getting machine errors on BC2. Turned out my CPU wasn't stable. Prime95 stable, but not BC2 stable. My QPI was too low, once I dealt with that I was able to bump vcore slightly and go from 4.2 to 4.4. BC2 and Prime95 stable.
