Hmm serious. I'd be worried about frying my pc on stock settings with 48 hours of linpack

Seriously - I agree. There is absolutely no real-world application that will work your cpu that hard. Why try to ruin it with a synthetic app?

I've gotten 4x 3849B018s and 2x 3849A925s to 4.0-4.1GHz without worries on EX58-UD3Rs with 1.152Vcore, HT and LLC enabled.
Hell, they all use the exact same voltages and settings.

But there were reports similar with the early Q6600 G0's. It was later batches where people really started griping that they couldn't push them as far. I have a feeling that is coming here soon.

*scratches head*

Because too many people assume..

Assume = Make an ASS of U and ME

Im running 4ghz on my 860 but its with HT off. Temps are maxing out in the high 70s. But with HT on lol temps hit 95.

The reason I ask this is.....



Is all the internet hype around the i7 920 D0 giving people the wrong impression? I know, I never really pushed my i7 920 D0 at all. I ended up selling it to my brother and got it up to 4.0Ghz after battling with settings for quite some time. Even at that, it still runs VERY hot and IMHO, 3.6 seems to be a more reasonable clock.

I think for the i7s the thermal limit seem to be the problem for most people to get over because past 3,6 it practically boils. any cooler short of TRUE/ProMeg caliber is toast at 4ghz with HT on. personally since I don't own one I can only read the reports from those who does, it seems this chip can indeed hit like 4-4,2 but you need cooling, lots of it. I think this will be the way things are when 8/12/16/24 cores hit the market in the future. the OC will be limited thermally not by the oc potential of the cpu. I think air coolers has reached the max performance limit and water should soon be the tool for us OCers in the future. this seems quite well illustrated in the i7s.

Not true. Depends on what kind of Vcore you're rolling to get to 4GHz. 1.152V with LLC and a non-uber-expensive HSF (Xigmatek Dark Knight) keeps my 920 comfy when Folding. Is it hotter than I'd like (~68-72C)? Yes. Catastrophic? No.

That's my brother's problem. He can get to 4 but the voltage it requires makes the chip run so hot with HT on that even water cooling isn't handling it.

The flip side of these is also likely lower grade hardware. Everyone assumes that 4 is easy and ANY old motherboard will get you there. While it MIGHT, the lower class motherboards may require more voltage which means more heat.

I am perfectly happy with my $170 motherboard and 3.9 and 68c full load with HT. I would say $118 motherboard, since there were open box, and I should have gone for it. They are going up now !

I can say that, because I grabbed it! ():awe:

Thermal Limit... 404 error not found in aigomorla's vocabulary.

Yes, and I see you have it. Whats your chip at ? speed and vcore and settings.

mine is 3.9 (195x20) 1.3125 and load with HT 68c all cores loaded.

I'm eventually use this machine as my AVCHD NLE (Adobe Premier Pro CS 4) machine so I don't want to push it at all. The other rig I'm building has a D0 with the Batch# very close to the i7920 D0 Anandtech used on the 760 Classified. It was luck of the draw with it. When I get my Enermax 1250 for it I'll continue building it, but as for now, the savings I'm making from NOT completing the build are very nice. Seems the 760 likes the Evolution with a S/N of 95xxxxxxx and above; for compatibility reasons, otherwise i'd have atleast another 2k on my credit card. And even though I do have a TRUE on the Asrock rig, I just don't like high temps.

I wrote a long post, but when I pressed submit, the forums were down :C Dont feel like typing again.

In short, I think all D0's should be able to do 4, just with good cooling and competence. Also, I think the Q6600's had a wider range of OCability. Mine, which isnt that great, still has no problem with 4 GHz. maxes at 4.2 though.

AFAIK, Q6600's max somewhere like 3.2-4+ GHz, most 920 D0's 4-4.5 GHz. I think there is a wider range of max oc's, so the situation is a bit different, and I dont think the D0 is the new G0.

There's the problem. EVERYONE expected all Q6600 G0's to do 3.6 and they didn't. Plus, the 920 D0 is still fairly new, later batches may be as crippled as the later G0 batches were.

I doubt D0s with HT on are stable with less than 1.35vcore. Secondly, I doubt anyone, even with water cooling can run D0s at full cpu load with anything over 1.25vcore.

Anyone can say they run their cpus at 4+Ghz, but they fail to mention any stability testing, which means their "stability" means they can game or surf the net without it blue screening/erroring.

Stability in any overclocing is a relative term. But in my opinion, any instability equal long (and short) term data corruption, and that will never happen with any of my overclocked settings.

I can run my D0 at 4Ghz with 1.2vcore, but need to disable HT to achieve this. But I don't need HyperThreading, and only max cpu clocks matter to me, as this is primarily a gaming rig. Of course my stability testing is more than just gaming, but a battery of testing including Prime95 for days without erroring, and using maximum memory to load the onboard memory controller hub.

I got a 3.62 on my DO i7 on stock voltage. I am limited because I'm just using a $40 air cooler. I got it to 3.8 stock voltage but it was too hot. I have HT on.

I run with HT on, and 1.3125 vcore, 3.9 full load 24/7 (F@H) No problems at all. That blows both of your assumptions down. And I use a air cooler (megahalem)

I think this is the major issue that we all see. With the differences in hardware and cooling, people are "expecting" to hit certain clocks but the fact it, there are just WAY too many variables for this to be realistic.

I think that is what we both are saying. I have 4 or 5 Q6600's right now (lost track) and they range from 3.2 to 3.5 ghz. I hit the magic 3.6 once, but over the years I have had to take it down to under 3.5, and my 920 D0 NEVER was stable at 4.0

All these expected OC's are just not right. Too much exaggeration.

Hmm, I do not know much about F@Home, but does this application check for errors? My assumption was it does not, so you may think your OC is stable, but in fact, you may be generating erroneous results for your number crunching.
