I7-960 ---D0---- Need some help

post #1 of 9
Thread Starter 
I started with a 4.0Ghz OC 160x25@1.3125v

Then i tried 4.2ghz, and i am currently stable@ 200x21@ 1.39(ish)v


Problem is when i try and take it to 4.6Ghz it wont load, even with cpu voltage on auto.

I have my ram set to xmp settings


How can i get my rig to 4.6ghz.... please help, no reward for the correct awnser...LOL


but thankyou..

Yeah...

4.6Ghz is rare for these chips, you might *MIGHT* get that on a full custom loop and that's with a golden chip.

The likelyhood that you'll hit 4.6Ghz is slim tbh. If you really want those sorts of speeds the only thing I can recommend is sandy. Considering, you're having to push 1.39v for 4.2 is a lot. I've got my 920 at 4Ghz at 1.29.

Sorry

well, like i said, i had 4.0 ghz @ 1.3125v.. so not far off of what your at.

Im not sure why 4.2 requires so much more voltage, im guessing the higher bclk.

My cooling isnt the issue. i just cant seem to get it to boot.

Are there some settings i can fine tune that might help>

Ive seen others with the same chip, at 4.7ghz, wondering how they got there... same chip, same revision

Because each chip is different, it'll have a different quality of silicon, they could have a golden chip and no, your cooler isn't really enough for 4.6ghz. The second you bench your machine for stress testing your temps will rocket.

Then you've got differences in motherboards. They could have a better build of board. The components are going to be slightly different. Tbh just because one person got 4.6ghz doesn't really mean everyone will.

And I need 1.34v for 4.2ghz so we're getting a bigger change in voltage. You'll end up needing 1.45 or more for 4.6ghz at which point it's getting dangerous for your chip.

okay, well, is there anything i cant change so that i can lower my voltage more @ 4.2 ghz? ive only tried to play with cpu voltage, and what xmp sets for my ram...

You can try to raise your VTT/QPI voltage a bit, it often leads to better stability and allows you to lower VCore some.

I've got my IOH/ICH set to 1.2 which helps a bit.

Lower VTT?
I on that road as well to get 4.6, and I can boot and everything it's just I get freezes in linx. I am thinking it's a memory issue, however I stop after a few tries cause this overclock is just for another website's overclocking club and I would need to get at 4.6 to be top dog.*which I think I can achieve..
As said above, everything is taken to account because of different variation in the building process... I have a 920 D0 which I think is quite a good chip*or so I've heard. but again.. we have different cpu's all together.
Good luck..
And don't give up.. only give up after you implemented the proper cooling solution!!

okay, so i enabled line load, instead of auto. ANd i set back to 160x25 for 4ghz, and i managed to get my cpu voltage to 1.3v


My qpi voltage is 1.4, and my dram voltage is 1.5 as per xmp settings.
