fmajor007 Posted May 16, 2009 Posted May 16, 2009 Can someone help me gain more information about my CPU? I'm wondering if i have one of the "Holy Grail's" of OC-ing - a nifty, new i7 920 with the D0 stepping. Hopefully, you will see here a screenshot of my PC with CPU-Z window up..... Thanks! PS - the background photo is mine. Quote Share this post Link to post Share on other sites More sharing options...
Zertz Posted May 16, 2009 Posted May 16, 2009 That's an engineering sample, so it's a C0 and the memory multiplier and QPI are locked. They generally clock a little better than retail C0's but it's certainly not a D0 Quote Share this post Link to post Share on other sites More sharing options...

Praz Posted May 16, 2009 Posted May 16, 2009 It is a non-retail CPU released by Intel for testing/evaluation purposes. From a legal point of view should not be sold as it always remains the property of Intel. Quote Share this post Link to post Share on other sites More sharing options...
fmajor007 Posted May 16, 2009 Posted May 16, 2009 (edited) Well i've spent a little time looking into this "Engineer Sample" thing and am feeling kinda sick..... With all the "Locked" QPI and such how can i OC my CPU? The Corsair Dominator 1600MHz RAM i bought won't operate at it's full capability and again, i'm feeling kinda sick.... Honestly, i'm a little honked off. I didn't spend ~$300 for a cripled OEM/Engineer Sample CPU - i bought a full RETAIL version. I just fired off an e-mail to a newegg Customer Satisfaction Professional (we're past the CS Managers here....) asking about this. However, what do you all think? I've had the processor over a month so return is a problem not to mention where i actually am located.....shipping is a nightmare.

Praz Posted May 16, 2009 Posted May 16, 2009 Doubtful it is anything bu retail if it came from NewEgg. Use the newest version of CPU-Z and see if the CPU is still identified as an ES. Quote Share this post Link to post Share on other sites More sharing options...

Praz, you da man!!!! Yup, i just installed the newest CPU-Z and low and behold, i found i am the *proud* owner of a stark raving average C0/C1 Stepping Core i7. Well, i'm at least thankful my spendy Corsair memory will be useable at it's full potential AND i can OC a bit. Thanks a million! fm Quote Share this post Link to post Share on other sites More sharing options...
Praz Posted May 17, 2009 Posted May 17, 2009 You're welcome. It would really be a blunder to get an ES from NewEgg. Quote Share this post Link to post Share on other sites More sharing options...
DLS2008 Posted May 17, 2009 Posted May 17, 2009 You're welcome. It would really be a blunder to get an ES from NewEgg. Yes it would as you're not even legally supposed to have them... However, have fun with the 920, many people are getting the C0s up to 4GHz+ easily. To tell you the truth, the D0 isn't as great as people first thought. It has turned out that only some of them are better clockers than the C0s. Some of the D0s are no better than a C0... Quote Share this post Link to post Share on other sites More sharing options...

Thx Praz/DLS2008 (You're from Warren? I had family in Dearborn, but i grew up near/around Cadillac then moved to Grand Rapids and now live in Sarajevo - small world) I'm pleased that i have a C0 and not the Engineering Sample - that would have been, well a big 'ol load a cr*p.... Also it's good to hear the C0 has a good OC capacity. All i see lately is how only the D0 stepping can OC very well and the C0 cranks up the temp too much to get to 4GHz (i'm on air and won't go to LC) so this is really good news for me - not that 4GHz is the *magical* number, just that the speed is there if i want to try it. fm Quote Share this post Link to post Share on other sites More sharing options...
Glow of fire Posted May 17, 2009 Posted May 17, 2009 However, have fun with the 920, many people are getting the C0s up to 4GHz+ easily.

Where are you getting this? C0 stepping 965's have trouble getting to 4Ghz at the same voltage that the D0 920's get there at. C0 920's can definitely get to 4Ghz, but they need quite a bit more voltage than the D0 batch. And most of them disable HT to do so. The D0 batch has a lot more chips that go way past 4Ghz. One thing you can say about the D0 is that they put out heat as they attain these extremely high clocks. But then again, that is to be expected. Of course some of the D0's are not better than C0's. All CPU's are unique. the 920 is the lowest binned Nehalem. So the current improvements for the D0 doesn't mean all chips come out very nicely. The better ones out of the lowest C0 bin will definitely be better than the worse ones out of the entire New Nehalem wafer. You may just be unlucky and get a bad OC'ing D0. You can prevent this by getting a 940, but that is probably a waste of money for most. Quote Share this post Link to post Share on other sites More sharing options...
Zertz Posted May 18, 2009 Posted May 18, 2009 However, have fun with the 920, many people are getting the C0s up to 4GHz+ easily. 4GHz+ isn't that easy, it varies a lot between samples. Apparently, the 975's are going to be awesome (and expensive!) overclockers Quote Share this post Link to post Share on other sites More sharing options...
