TPU's Core i7 Overclocking and Feedback

[DOM]

Ok i raised the PLL to 1.9V and the QPI to 1.4V and i did 2 hour OCCT CPU test on max level and a intel burntest on max for 5 passes. NO LOCK UP

I will let it idle to see if it BSODs

run 8 threads auto doesnt put full stress on the cpu most i seen is like 50%

also can you take a ss of TurboV with the more settings tab down ?

You are stressing it on auto level which only uses 4 threads. Maybe thats why you bsod, you arent stable on 8 threads.


Am i right saying that auto only does 4 threads?





EDIT: I am late, went for lunch and posted it sry

Ok i will back down my pll to 1.8

its just since ive done some minor voltage bumps to certain things, it has lowered the BSODs

I did 15 passes of intelburntest last night and no BSOD. plus after it was done it idled all night and no restart

If you take back to 1.8v and it BSOD's, lemme know. Try putting it back and then test again.

FYI - it is always best to adjust one thing at a time. If you go in and change 5 things, you don't know which one made it better (in this case) or (more commonly) made things worse. I know it's a pain in the ass, but it works. It takes a lot more time though, which is why I don't push my stuff as hard as I probably can.

i got my 920 to 4.1...lots of trial and error

 

[Rolin]

i started overclocking 3 days ago and so far its still stable

There's no need to double post. There is an edit button.

 

[brandonwh64]

Like another mod has pointed out, PLEASE stop double posting and reedit your previous posts

 

[Rolin]

i know ...i used the back button in my browser to post to a different thread and it put it here instead

and yet i just diod it again ...sorry guys

 

[FilipM]

Why doesnt my system display Bsods? Screen just goes black and then restarts afte a while

You should be able to turn off automatic restarts under advanced system properties.

is it a stable oc ?


whats the highest vcore you wanna run for daily use guys ?

 

[Lionheart]

Yo guys, I got a 4.0GHZ OC on my i7 920, my CPU voltage is at 1.44v and I know thats too much for it, wat do you guys have it at?

 

[FilipM]

I know what the reason is - QPI Link speed. If thats high then the CPU needs way more voltage.

Is that saying a bad memory controller on the CPU or Board?

@DOM - under 1.3V for 4Ghz and i would be satisfied

This has been discussed quite a bit. Voltages on these chips are all over the place for 4.0, so you really can't compare. In the dozen chips I've tested, I've seen everything from 1.22v to 1.425v for 4.0. As I mentioned in an earlier post, early batches seem to need lower vcore for 4.0 than newer batches.

IIRC mine is between 1.4 and 1.45v for 4.4GHz

This is what i use for 4.2GHz might wanna try some of the settings idk how your bios is but might help you get 4GHz under 1.3v

the ones i changed it to worked better for me then the ones i had it at, i had got them off some other guy on OC.net
but failed LinX after 13m so i went back to what i used when it passed 20 passes

Yo guys, i just decreased my voltage down to 1.4volts on the CPU, windows booted fine and all, used everest to see my temps, I ran a quick test just to see how high my CPU temps would get, ran everests system stability test for about 1 min, the CPU got up around 69C - 72C, the cores were around 81C - 86C then I stopped it, the cores decreased in temp but the CPU didnt, it stayed at 72C so I started up everest again just to see if it would read it again, but it was still at 72C, so I rebooted the system and checked the BIOS for CPU temp and it was at 72C still, then I got booting issues so I put everything back at default settings and now its booting but the CPU temp just stays at one specific temp, do you think my CPU could be damaged or maybe the CPU cooler is too tight on the CPU, any help at all guys, I would be thankkful!

 

[Lionheart]

I dont mean to be a douche ut I seriously need some help!

 

[Chicken Patty]

I would try to loosen the cooler a bit. If not either the sensor or something is up with the CPU.

Ok, that doesnt sound good!

 

[Chicken Patty]

I'm pretty sure the sensor is on the CPU itself. If it's reading wrong then in should be a faulty sensor. Now why did the sensor go bad, damage to the CPU perhaps? I'm posting from my phone while at work. I can try to find out more info when I get home later today. In the meantime try to find out if the sensor is on the CPU itself.

 

[Lionheart]

Ok now its showing my CPU at 56C - 57C and all 4 cores are at 50C, NB is @ 51C and SB is @ 49C

something must be wrong with the CPU sensor!

How many threads do u need for this question? I told you already that the sensor is the problem 4 hours back in another tread that u started. Keep it one please please.
