Without hyperthreading case enable you only use 4 of the 8 threads m8.
Thanks roller11, I had 4600 going for 12 mins, but every v I touched after that it ran even less. Maybe something to do with the components delivering power on the mobo. I hope to get a full night at it this weekend. I'm right at the point of this cheaper corsair needing the 6x ratio, but I had the timings set manualy. I hadn't been paying attention to the hi speed runs before, as my c0/c1's were mid pack chips. Of the 40-50 cpu's I've owned over the years, this is as close to a "golden" one as I've had, meaning the xx20 series. How it fairs against the other D0's as they emerge, time will tell. But it is a nice way to come back to the hobby after 5 years off :D I want to start reducing the voltages, especially QPI/VTT and a few of the others to see if they are actualy needed, fine tuning basicaly, and a H/S remount. I'm hoping to get a 4.5 stable enough for a 24/7 setting, if not then somewhere around 4.4Quote:

He'll be picking on you now... :)Quote:

^I wouldnt be to worried about this lol
In my experience on 2 different 920's now, I can pass the Linpack 20 pass with max memory use and problem size but will still fail prime if I leave it overnight.Quote:

Prime lost it's value as a stability tool for me when a 10 hour prime blend stable failed in 1 second of linx, full memory, high work load. And it's not just me who have experienced this...
I'm still looking for the optimal overclock of my D0 Batch 3849A846 for 24/7 usage, I use my core i7 system for batch converting RAW files about 20~30GB of data at a time, and also use it for HD video editing so my rig must be able to sustain heavy cpu load for extended period of time and it has to survived through the summer heat. So far this D0 chip is mopping the floor of the C0 it replaced, my C0 can only do 3.6Ghz with HT on, at 3.8~4.0Ghz the HT had to be off and it needed 1.37vcore to reach those speed.
An initial test at 4.30Ghz (21x205) @1.32vcore

4.30Ghz with HT on, need a slight bump in vcore and vtt/PQI
http://bcphoto.org/misc/4.3hton.jpg
As you can see with HT ON and slightly higher vcore/PQI it runs about 7'C hotter, with my current air cooling I'm not sure if I feel comfortable with this chip approaching 90'C underload, my HAF 932 case has plenty of airflow, and the Noctua NH-U12P has two Silverstone (110cfm each) in push/pull configuration. I think this D0 chip have more headroom left but suppressing the heat with air cooler is quite a challenge. I'll have to put it through 100 passes of LinX once I found the best compromise overclock for 24/7 usage.

Does your 24/7 work load benefit fron HT on? If not, turning it off buys you a budget of less vcore/more CPU clock that you can spend in any proportion you like. Also,
what CPU loads are your RAW file convertions and video editing producing, and what temp levels?
What I especially like about your post is that your D0 earns you more than just bragging rights, you get real world benefits from the extra power of the D0...great results!
Usually I let the DPP convert RAW files in the background while I do the editing of the finished data in Photoshop CS4 or Lightroom 2.3 simultaneously, the HT definitely help and my cpu load hit 100% load on all 8 threads, I don't think the calculation is as intense as LinX as I haven't seen any of the core hitting 80'C, but the duration do last for couple hours, it depends on how much data I needed to crank out. Less than 10GB I should be able to get away with HT off, but 20~30GB of data would save me some valuable time with the HT on. I guess whenever I have a chance I'll have to bust out the stop watch to do some comparison test with HT on and off to see how big of a difference it is.
What is a "stability tool"?Quote:

Nice haya but you have to fix that pic.

Maybe a better question is "what is 'stability' "because there seems to be a lot of confusion about this easily defineable word.
I agree he certainly could have handled that better.Quote:

Stable to me essentially means that when a game or app crashes I know it's not due to my overclock and I dont have to mess with it. For instance if I haven't passed Prime overnight for at least 12 hours then when an app crashes it could be because of my overclock or it could be because of any number of other things and it makes troubleshooting way too time consuming. I'd rather just get it out of the way up front and never have to deal with it again :)Quote:

What purpose other than stability do you use these for dude? Didn't think so, now please lay off the bullsh**. Thanks for the much needed lesson :PQuote:

Linpack solves systems of linearly independent equations. As to "stability",
there is no such thing as a program that guarantees stability.
And that's no bullsh**.

I just have to ignore him now and wish him the best of luck. You really can't spend that much time or energy on someone who can't grasp on to the big picture. In the working world, these tend to be people that are let go in slow times or never promoted. They latch on to the small words, the small ideas, instead of grasping the big picture: Data Validity.
