Since I got my i7 975 Extreme Edition, I have gone to a few OC forums for advice since it's not like OC'ing previous processors.
But I get a lot of flak from people that say I should never have bought it, should have got a 920 or 940, yade, yada, yada, so on, so forth. They cite the obvious huge money savings and seemingly feel smug and superior and imply you are a dipstick for getting the 965. Also they say they can get the same out of their 920 and so think you wasted your money. Huh?!?! Well, when I have an unlocked multiplier and they don't I seem to feel a little better about things after all. So no, they can't get the same thing out of theirs. Only seems to me they are just envious. And besides, I could afford the thing so why don't they stop bothering me about it?? Sure, they got a lot of bang for the buck overall but they should shut the heck up. I gave up on those forums, figuring it out myself. As long as you know the voltage limitations and watch the temps you are fine experimenting. Almost forgot about the ones that say I should have waited for the 975 and got it instead. Only trouble is, I didn't know about it and also it's the same anyway except for a slightly higher clock speed to start with. |

Try www.overclock.net, that's where I hang out and most people there are helpful.

What frequency have you got it up to? When a range of processors all overclock to the same set of average limits, it makes sense to get the cheapest. If you exceed what frequencies the 920 users have obtained, then you can pat yourself on the back.
Exactly. It puzzles me as to why there are so many threads like "help me overclock this processor" when it's often a common case, and the vast majority of existing identical threads don't yield any more information than what you've just said about voltage and temperature. ---------------------------------- Flying online as 453_Whittle E8400 @3.8, 9800gtx+ Phenom II X4 B50 @ 3.4  Uni-joint / hall effect sensor stick guide: http://www.jpfiles.com/hardware/uni_stick.pdf |

I've noticed that many denizens of the overclocking forums are way more concerned about benching and posting their "achievements" than they are about using their PCs for any practical purpose. Reading these adventures can be fun if you want to marvel at the seemingly-endless finances some people have. I love the ones that depict people removing covers and lapping their processors until the circuits are revealed - oops! Or the " I clocked it to a zillion Mhz and it remained stable for a nanosecond - guess I'll buy a new processor when the stores open on Monday.."
I guess it's safer to have these speed freaks safely tucked away inside their houses. They might otherwise be out over-clocking their mopeds and endangering the public.  I agree it's frustrating trying to get a sensible answer on some of these forums. It takes a while to get used to who wants to help and who wants to play the one-upmanship stuff. B |

Yeah people on the internet can be a bit annoying and elitist when you need advice with computer stuff. You need patience and to ask the right questions, unfortunately it can take a while to figure out what to ask if you want the right response.
Fortunately this board is really good for help, people are very down to earth and if you are persistent they can tell you exactly what you want. ----------------- Farewell to freedom in the Adriatic and to the days of wild abandon.

Try the forum Urufu_Shinjiro linked I'm on there quite a bit on the AMD side and the they are pretty helpful.
The i7 975 will clock easier and from what I've read on different forums will overclock higher than the 920 or 940 with lower voltages for the most part. |

Glad you like you I7 975 extreme edition. Or is it actually the 965. The rest of your post seems to intimate that.

Indeed, since you can OC with the multiplier alone you can easily get to 4.0Ghz with scarcely an increase in any voltage whatever. I got to 4.1Ghz with nothing more than the multiplier and passed prime95 using several tests for extended periods. A 920 user can't claim that. They can get to that frequency but it's more difficult for them. I got there by hardly more than uttering a sigh and clicking on something. People with the lesser processors can get there too but only by increasing the BCLK frequency which takes the memory frequency up with the processor speed. If I want I can only use the multiplier, the multiplier and the BCLK together or the BCLK by itself. So I have more avenues than they do. I do feel the 920 and 940 processors are good processors for the record. Their cost to capability ratio is superior but they are overall snot-nosed siblings to the 965 and 975. |

Do I hear a LAH LAh Lah!?(Fingers in ears.
 )If you post on IL2 Forums you will get IL2. user answers. Why would you require an O/C to 4.0Ghz. When you can run this SIM inside out with your standard set up? If like myself you have found that O/C is easy with your new PCU. and you would like to take advantage in other Games/Sims So be it. However this particular Sim will run "Fine and Dandy" with your Rig. Other platforms may require an upgrade in the Graphics department.  As far as Voltages are concerned. As long as your CPU runs stable temps. (Mines struggles to break 50degrees.C running this SIM). Why worry? The only real plane I have ever flown in.(Pah! Booked for Florida next year.

Because some of the newer 45nm chips run so cool that you can actually run enough voltage to fry them before you reach dangerous temps. With the i7 that is unlikely since their four cores tend to run a little on the warm side, but with the 45nm dual cores they can indeed get damaged on voltage alone. -------------------------------------------------------------------------------------------------------------- Flying online as NORAD_Shinjiro |

I'm stoked that you were willing and able to go for the best. Anyone bad mouthing your decision is deluding themselves and is missing the point. Here's a reputable, no-BS guide on overclocking the i7 from MaximumPC. Enjoy, S!

Mortoma and I are both running i7 CPUs (4core hyperthreaded 2x per core) the 45nm chips run cooler full stop. This allows for O/C without the need to overvolt as much? Lessening the degree of collapse. There isn't a problem? All you will get on Bootup is O/C failed to post. (You don't kill the system). Gone are the days of fried M/Bs. Too many inbuilt Safety catches.  Forums are now full of "Novices" O/Cing their systems. No? Overvolting can induce higher temps within the confines of of your system case. However proper cooling of the CPU. can alleviate this problem. If this thread has now turned into a My processor is bigger than yours thread. Well It would appear that the point is. "Well Lost". So apart from stating the "Blooming obvious". What are we trying to establish? The i7 965 is bigger than the i7 920? Well I'll agree with that. Along with everyone else in PC. World. If the point Mortoma is trying to make is that O/C Forums are full of Elitist benchmarking bigots.(and he couldn't handle it?) Good and well? However to post on this Forum about how "Uber" His PCU is and how others fail to see this. Is just as big, an elitist view. IMHO. The only real plane I have ever flown in.(Pah!

on that topic,
anyone here ever overclock a laptop?? I went through this rigmarole a few months ago, and people recommended various programs that i downloaded but werent compatible with my system drivers or hardware, or just were way off for being able to do what i needed. Its not really a huge necessity for me, but id still give it a crack, being as my core temps never exceed 55C when pushed. So i think i could push more out of the CPU, but so far nothing can crack this thing as far as getting past its safety features and integrated components. So go ahead and recommend what you can or know, but i might have already tried it. thanks |

I've found that overclocking my i7 920 is the easiest overclock I've done out of the dozen or so pc's I've built over the last 8 years. The key is getting a really good CPU cooler and I got one of the best air coolers on the market (Thermalright TRUE copper limited edition with dual 120mm push/pull cooling fans).
I let it burn in for 2 days and couldn't wait any longer to see what it could do. I did alot of reading and decided to do it the ignorant irresponsible way. I bumped my Vcore to 1.35, set my Dram voltage to 1.66 and set my Bclk right to 190 for a 3.8Ghz overclock. It booted first try and I ran 8 instances of Prime95 for over 11 hours with no overheating and was humming right along when I finally shut them all down. It peaked at 76c, but settled out at 73c and stayed there for the remaining 9 hours I tested. I have it turned down to 3.4ghz right now as I just didn't see a difference between 197fps and 138 fps and decided summertime in Florida could reduce the lifespan at those clock speeds. Running Vista Home Premium x64 on the following hardware: ASUS P6T Deluxe V2 Core i7 920 6GB Corsair Dominator 1600 300GB Vraptor (boot sector) 500GB Seagate 32MB cache (data/games) XFX GTX285 black edition X-Fi Titanium Fatal1ty Champion Coolermaster Stacker 830 (yeah, kept my old case...it rocks) My old rig was a Core 2 duo E6700 @ 3.2ghz and it ran this sim like butter, but in other games/sims the difference is already more than I expected clock for clock and in RoF (which is optimized for multiple cores) average frames are double. At this point I have 3 BIOS profiles saved and set my clock speed relative to what I'm doing with it. I run it stock 2.67 when I'm watching video or surfing the net, 3.4ghz for older single core games (like this one) and 3.8ghz for the latest titles.

Have you experimented to see what the lowest stable voltage for 3.8ghz is? -------------------------------------------------------------------------------------------------------------- Flying online as NORAD_Shinjiro |

Thunderbolt, it looks like you're limited by temperature... What cooler are you using?
I strongly recommend intelburntest for testing intel processors.... You are absolutely guaranteed that you can't load up the processors any more than with this program, and it tends to find faults faster than prime. ---------------------------------- Flying online as 453_Whittle E8400 @3.8, 9800gtx+ Phenom II X4 B50 @ 3.4 Uni-joint / hall effect sensor stick guide: http://www.jpfiles.com/hardware/uni_stick.pdf |

Actually, I didn't experiment with voltage at all in that regard. I intend to, but simply haven't due to the performance and stability as is.
Regarding temperature and type of cooler; I'm using a Thermalright TRUE copper limited edition with dual 120mm fans in a push/pull configuration. As far as temps go, my temps seem to be right in line and are well under spec limits. Most OC sites list 90 as an upper limit with <80 being easily stable. I haven't even approached 80c yet and, honestly, don't intend to as I won't even attempt to go over 3.8ghz until there's a need...and right now there's no need. Heck, like I posted, there's no need to go over 3.2 right now and I'm running everything I play at highest settings at 3.4 right now. I know I've got 400mhz in the bank if I need it.

Surely you had to have changed your ram timings too?? |

Whoops, just noticed that I didn't read well enough... I don't think you can get a better heatsink than that. So it seems that the i series simply runs hotter than the E series. Obviously it's doing a lot more work too though. Personally I don't see the point in waiting to overclock. Either you have a completely stable overclock, within operating limits, or not. You might as well find the best clock you can get whilst staying within voltage and temp limits, and leave it there. Unless, of course, you want to get 20 years out of your processor... ---------------------------------- Flying online as 453_Whittle E8400 @3.8, 9800gtx+ Phenom II X4 B50 @ 3.4 Uni-joint / hall effect sensor stick guide: http://www.jpfiles.com/hardware/uni_stick.pdf |
