TPU's Core i7 Overclocking and Feedback

I was unsuccuessful in finding what the error in LinX I was getting, I was wondering if anyone can suggest anything else. I am able to get the Base clock up to 208 with a 19 multiplier and it will post and boot into windows fine. I can run 3dmark 06 and vantage fine. Now I tried what chickenpatty recommanded, I lowered the QPIlink speed to slow mode, and it went from 3900mhz to 2300ish, and that did not work I still got the error within 10 minutes of running LinX. I ran Memtest +86 2.11 and my memory passed 2 full tests, it was running at 1640ish when it's stock rating is 1333mhz at 1.5v 9-9-9-24. I have it at 16940mhz 9-9-9-24 at 1.60v. Now I can not lower my QPI Link speed at all, since I have no control over the multiplier there. I also tried lower my memory and uncore multipliers, from 4 and 8 respectly, to 3 and 6. Now the computer would not post nor boot. Then I tried 3 multi memory and 7 uncore, no luck> I am going to try more, but I do not know where this error is from and how to fix it. I also have not done a full prime 95 test, it ran fine for 30 minutes, but I will be letting it run loonger and see where it goes. Now also with my mulitplier of CPU at 20, I can not get my base clock over 186mhz. I have tried increasing all the voltages and still no luck with getting it over 190 with a 20 multi, any ideas? A few posts ago I listed my BIOS settings, I do not have them infront of me now.
 
Can you complete a super pi 32m run?
 
Well, it looks like I got screwed. The guy I bought my 920 from said he dropped it and scratched it, but he told me before he was getting a D0. I bet the new one he got was crap so he decided to keep the C0.

Now I need a CPU and fast :mad:
 
4GHz on air (NH-U12P), OCCT for 4 hours.
Not really impressed, but at least 4GHz with HT is at last do able in my case for air cooler.

Kid did you check out the Prolimatech Megahalem it's available at sidewinders? I mean it's the closest thing to water cooling you'll get on air other than a V10, but I've seen such mixed reviews. :toast:
 
A Question for you all,
I am stable at 3.4 but when I run the sensor test in Real Temp my multiplyer drops during the cool down stage. The multiplyer stays at 21 during heat up and my temps go from mid 30's to mid 50's , not really bad and much better than previously (I had a Zalman 9900 which was not cooling well). But.... during the cool down test my multilier drops from 21 to 18 then to 11 then finally to 3 at the last stage giving me a very low core speed. The temps do not climb any higher while this is going on and in fact they start to come down during the cool down phase but still the multi drops. When the cool down test is finished and all cores drop in activity the multi imediatly goes back to 21 and temps are by then back in the mid 30's. I have tried this with hyperthreading enabled and disabled but it is still the same.
I have C1E disabled, C-State disabled and Speedstep is no longer visable.
Is this normal? Any ideas?
Perhaps it is memory related. I had a non functioning Dominator GT dimm so I am running on two for now. My three new DIMMS will be in tomorrow sometime.
Perhaps Win 7 related? I don't think so but anything is possiable.
 
What motherboard are you using, and could you provide a filled in bios template?

Yeah, these chips run hot....and basically beg for water cooling. What's your vcore?

mine idles @ 81c on water and 4.3
 
You need to fix something :p Don't scare anyone.

I will check out that cooler when i get bored with this one :D.
But, i barely see a different between my old Z600R and this cooler (~2C), beside this noctua have way better airflow.

What mem divider are you running? Have you tried lowering your mem divider? When you say you increased voltages, what did you increase them too?

Great job kid :toast: HT on 4ghz on air is very good :respect:
 
okay question again. I tried running it now with a 19 multi and a 207 base clock, it errors on Prime 95 large FFT and Orthos when running it says Error, the rounding was 0.5, but expected 0.4. I can not run a full 32M of Super Pi, I can run 16M but not 32M. I am thinking my RAM is the problem, timings maybe?
 
Chicken patty
I have a 4 memory ratio and an 8 uncore ratio at the moment. I can not post or boot into windows with any thing lower for now. I have not tried 2:4 or 1:2 yet, but that would be a killer on the RAm speed. I know that 3:6 does not work.
The voltages for the ram? If so I ncreased them from 1.50V to 1.60V which this Ram is rated for. it is rated also for 1333 speed, am I pushing it too far trying to run 1620+?

I have tried voltages on Cpu from Vcore up to 1.192V-1.408 (+.250V), QPI 1.12-1.33V(+0.210V), PLL I tried 1.80-1.88, Dram is set at 1.60 and I have tried differect IOH and ICH, now IOH from 1.10V to 1.30V and ICH from 1.50-1.65V

you needed skewing to get a stable oc???... Ugh... this is why I sold my RIIE. I would randomly get my multi turned off for no reason at all. Great board but not for the i7 920

Try turning speed stepping on as well as turbo on. If not this is a troubling "problem" you have but you even said it doesn't turn 21 multi off under load, just when the processor is "cooling down".

on my board that would be a mem divider of 2:8 and 16x on the uncore. try the mem at the next lower divider.
