Working for me, thanks!

Thanks for the post, really appreciate it. I have not had any problems yet so far. There is one thing though that I am unsure of. I am really new to this and this is my first overclock, so I am wondering why my CPU only shows 4 threads when it should show 8 threads. I followed the post almost exactly, the only thing I did differently was use a slightly lower VCore voltage (1.45) for the CPU. Do you have any ideas on what might be causing this? I have the i7 920 and 12GB of corsair 16000 at 9-9-9-24. Any help would be greatly appreciated!
Thanks,
Josh

Oh Lord! Can't believe this ancient relic was restored as is for the new forums! Please take this this thread down before someone burns their D0 with these kinds of voltages and settings. Times have changed and this guide hasn't. You don't need that kind of voltage for 4.5Ghz with D0.

I would recommend people look for Shansmi's guide instead of this one.

Could you plz link Shansmi's guide just incase I cant find it. Found this one How to Overclock the I7 here on the forums, Hope that is the one
 

Yeap thats the one I printed out and was reading along with the memory speed info link just below his post on all this. I am kind of wrapping my head around all of this. it just that some of it get confusing becasue in some of that the QPI is refered to as the CPU Freq and other times its the Uncore, and there is no tell tell sign which it is at that time. so I am trying to sort it all out in my head. And part of the problem is I am trying to get my ram stable, its a 7/7/7/20 at 1600 set, but when overclocking the speed, it turns into 1720 and I am not sure how to set the timing on it and volts but I am starting to get the volts thing. but the timing is throwing me. I will also put some of my specs in a sig now.

Anyone want to update this to the more recent BIOS?  This is some old stuff here.

You know, do a guide for the D0 with the latest BIOS.

Yeah, I know what both of you mean greenhawk84 and djenkins. I have search real hard for info on overclocking the Core I7 975. All I ever find is how fast someone has there system running. I am not new to overclocking, just overclocking the Core I7. There are so many different components to the Core I7. I would like a detailed explanation of the different voltage settings and what parts of the Core I7 they effect. Such as what voltage will make the uncore stable. I see many people running faster clocks than I am on less vcore volts but 1.35V is the lowest I can go and be stable. I just think there must be something I am missing here. Thats why I posted all of my specs and have not yet received any response or guidance. Hopefully someone will help ;-)\

Thanks,
Jesse

Thanks for the guide! Flame it if you want to but this was the first time my C0 got over 4Ghz. Ended up at 4.2GHz with my first sub-10 second 1M SuperPi run. The only deviation was using 1.375 Vcore...

I wish there was a way to "extract" and save your bios settings! I like the settings I have right now but I want more speed. Right now, I have 4.0 and though my system is "stable" right now, I did get two blue screens. I'd like to give your settings a shot!

sorry , wrong post

Just want to comment on your ram setup. Why do have go dual channel instead of tir? What is the point of the x58 Bloomfield then? You could have get P55 and 860 Lynnfield that will be way faster then your 920 and supports dual channel.

I see many of you think that you can just change some numbers and have it miraculously work. well that isnt the case. each individual piece of hardware is slightly different. each i7 is not exactly the same, there are variations that occur when the wafer is made and set ect ect. you have to find the sweet spot for your processor, ram and mobo. this requires many many MANY experimental increases in voltage, frequencies, and timings.
     A good place to start (after you conferm everything runs stock, at stock settings (meaning you have your ram set to its rated timings and frequencies, you may have to overclock your proc a bit for this, esp if you have 2000 mhz ram lol)) is at 3ghz for i7's. most will run that easy, you may not even have to change voltages. test it with prime 95 or another benchmark to see if its stable. if stable, turn the voltage down and repeat the process until it becomes unstable, or wont boot (it should just hard restart on you if its unstable during testing). then, knowing this voltage, you can safely plan ahead for higher frequencies, say you want to run 4ghz. set it up in the bios with a decent voltage (like 1.35) run the test, if its not stable increase, if so then decrease until you find the sweet spot. however, some processors might not run there best at 4ghz, maybe its 3.95, or 3.7 or 3.8. i7's, however, are not that finicky and should gain more processing power at higher clocks. you can do the same process with memory and timings, qpi ect ect. but keep in mind it is not safe to increase the memory voltage any higher than 1.7. experiment a bit, but remember, higher voltages means less life expectancy (for most hardware, pending on temperature), so be careful.
     you can do this same process with your graphics cards, however, most of the time, voltages are not adjustable, unless there is an interface designed for it. you can extract you bios from you gfx card, and change it, but that is for advanced users only lol. you can screw up your card pretty bad if your just fumbling around and try and reflash your video card. well, i hope this helped those of you that are new to overclocking, heck i am as well :P, be careful and have fun!

sincerely

oh, and btw, dont forget that just because its unstable, doesnt mean its just your processor. you have to make sure all the other components are stable too. for example, your cpu could be stable, but your memory not, even if your not overclocking your ram. so keep that in mind that you have to continually adjust and test each setting. it takes awhile, but is well worth the effort. and make sure you have a good PSU (power supply) or you could do some damage and undervoltage your stuff. bad for HDD's i tell u, and ram XD.

I already bought the motherboard.  From your advice and other research, I'm going to use 6 Gig for Triple Channel.  We have the same motherboard, ram and D0 series chips.

Did you use the EVGA E-Leet utility to overclock?

What is your cpu temperature, when running at a full load?

Thanks

 

No I never will use any software in windows environment to adjust the settings in the bios which also include overclocking. So no I don't use E-Leet to overclock anything or mess with any voltages. I use E-Leet to monitor temps or just check the cpuz screen for my cpu info. I set everything in the bios and my max temps at full load when running linx 81c on highest core. CPU temp is around 65c. So its fine. I'm happy with my overclock.
