Everyday OC on a 920 DO?

[Markfw]

Yea, and mine is like 1.28 something, and I am at 1.3. No wonder I can't get over 3.7.....

 

[spdfreak]

On my W3580, I set the voltage manually in the bios to 1.25v, upped the multi for 3.6GHz and left speedstep on. It still throttles the voltage down with speedstep on my board.

So it looks like 3.5-3.7GHz would be realistic with stock voltages and speedstep/turbo on. That will be plenty fast for what I do. I'm currently using a Q6600 at 2.8 which is as fast as it will go at stock voltage. I'm guessing that a good aftermarket cooler will still be needed at those speeds?

No, my chip is not a 920 D0 for one, and two, you should never assume anything besides stock is a given.

This.

This is why I laugh at "retards" that sell their previously OC'd chips in FS/FT with a premium just because it OC'd to X.X GHz in their setup.

While obviously this is true, I think that what most people (including me) are saying, is that 99% of 920 D0 chips will do 3.6 on decent hardware. I won't even go so far to say as on stock vcore, but I think the percentage drops to 80 or 90% in that case.

Also of note: It appears that my stock vcore is pretty high (1.28 something)

Perhaps, but many won't agree on what "decent hardware" is and buying a CPU with an OC expectation is a disappointment in the making. See my Q6600 Go thread for details. ;-)

Also, since he quoted me I wanted to be sure he knew my chip was doing 3.6 at a low voltage but it is NOT a 920 D0. Mine is a Xeon 3.33GHz stock chip so a bump to 3.6GHz is a nothing overclock, whereas going from 2.66GHz on a 920 to 3.6GHz is a much bigger step to expect on no voltage change.

My every day overclock is 3.78GHz (21 x 180) with 1.25V. Temps stay at low 70C at full load according to RealTemp. Specs in sig.

I've been running this 920 D0 for half a year at this speed and stability has been solid the whole time. It's gotten kinda boring actually.

How did you test stability?
HT on or off?
What hardware are you using?

These are the problems with these types of threads and posts. Anyone that doesn't know any better is going to assume that ANY motherboard and ANY cooler will get them to 3.78GHz with 1.25v, but you left out a lot of pertinent info.

Stock Cooler / Cheapest ASUS board in the world got me to 3.78 @ 1.2v HT On
Stock Cooler / Cheapest ASUS board in the world and Ill be at 4.2GHz @ ~1.3ish (not final yet) HT off

I may be upgrading my 920 D0 soon, if my buddy at Intel can get the ES to me. Still, 4.2 GHz HT on is pretty sweet. Still, my vcore requirement is a bit high IMO. Rubicon, you are lucky with your D0's

Like I said, mine needs just over 1.4 Vcore :O

My TRUE black does a pretty good job of handling it though.

Been running my rig at 4ghz since I built this i7 machine 3 months ago. Was able to run stable at 4.1ghz with tighter timings due to a motherboard bios downgrade. A little tight on money atm, looking foward to getting better gpu & hdd setup.

I found that a second fan did not bring temps down enough to warrant its use on a TRUE. The Megahalems did benefit from it and that's my current config. 4.45GHz 1.33V HT ON mid 70's Linpack after eight hours.

i'm going to test this out as the weather gets warmer as i'm in canada. Most of the benchmarks I saw with a TRUE dual fans showed a big drop in idle temps and only a little full load.

I'm currently using a S-Flex 1900RPM fan so two of those I would expect abit of a drop in load temps. This is on a controller aswell so both fans won't be running at full speed unless needed.

 

[imaxcpu]

920 DO's?

cough....vcore @ 1.36.....with one fan she was stable at 4.48...with 12gb ram 8-8-8-24. Maybe less after the AS5 setup, but this was just out of the box and we will have to vist the max and the min again sometime soon.





The 24/7 setup right now has been 1.32 v 4.2 12gb 7-7-7-20...cough

 

[Paratus]

Just realized I never came back to update his thread. Well I eventually settled for an OC of 3.33 Ghz with turbo engaged, so it basically always runs at 3.5 Ghz. I pegged the vcor to 1.18. In auto it would range from .97 at idle to 1.26 at load.

The folks who said the 9500 wouldn't cut it were right. I ended up with the CM hyper 520 as the largest cooler my case could fit, (push pull 92mm fans). The Zalman would hit high 70s under load. The CM stays in the high 60s.

Even after 2 years it's still a solid machine. Thanks for all the help!

Nice Necro lol

this is the most awkward necro i've seen.

Haven't been around much, huh?

Glad to hear it OP! With your speed, you might even be able to undervolt a tad and shave a few degrees off your temp.

I've been running an i7 920 @3.9GHz for 2+ years, still a champ in any game I throw at it. I see a bunch of friends jumping on the "next big thing" wagon, but I haven't felt the need to upgrade at all.

Its a win for all of us on Gen 1 i7.

You really don't need to look at anything until haswell or its refresh to be honest.

1366 is a socket that i will get 3-5 years out of and the only thing that has come close in the past for me was socket 939 which I got 3 years out of.
