Was that directed at me? Its on water, but the room started out @ 19C ambient, 21C at the end of testing. My cooling goes, 355 pump + Xspc top-Feser 120.3 with Yate loon "m" with shrouds-heat killer 3.0 - Switech mcr320 with yate loon "m"Quote:

220x21. With the biostar x58, asus, DFI, and MSI boards, I can get 220-222x21 (depending on board) at full speed. In fact, I just set my personal record with the biostar x58 with full speed QPI.
Now all the haters who criticized PC and said he was intentionally spreading false info.... you can eat your words and you owe PC an apology
I had pressure modded the CM V8 and cut back on the AS 5, feeling that I had to much the previous time. Wasn't impressed with the new temps, so threw a stock TRUE on, temps dropped 5c (probably the paste), with the same fan. Curious at that point, I lapped the HS, and the cpu at work last night, pressure modded the TRUE, and dropped another 10c so far. I'm not sure if the temps will drop more as this is on fresh AS 5. Inlet air temp is 25c, the fan is a Scythe 110 cfm cheapie, just going to pick up another bracket to run 2 and see what I get. After work tonight, I'll open the patio door to drop another 10-15c, to see what water would offer me.Quote:

Is anybody here to give me an answer how to get Blck over 222MHz and how to get 215 MHz stable on my Gigabyte X58- Extreme?
my board wont go over 222 either, not even on phase or DICE. Sucks a fatty for sure.
ah crap those Xeons look really nice, guess i can't resist and will get myself also one. :D
But need to wait a few more weeks till they are more available and no price gouging is going on anymore. ;)
but on the other hand its only ~10 more months to gulftown....

Take care of it.
Thanks for your pic, up to 4305 I just adjusted vcor and vdimm, I never had to mess with my other voltages on the C0 series due to limited bus speeds. Anyway I turned off HT due to the air cooling for testing, and ran an hr of prime small fft's, with the only difference being vcor 1.312 and vdimm 1.66 under load (compared to yours :up: ), cores ranged from 66c-72c in a 19c ambient. Once I find the limits of the chip and mobo I'll back pedal the voltages if I can. Maybe we can get this batch # a little higher on the Giga !Quote:

Thanks Roller11, I'll try in the next couple of days what it takes to get HT working at that speed, but this time I'll use the chill from mother nature. I'm no longer confident in my ram though, we'll see....Quote:

This is a kind of petition.
I am sure (I tested by myself) that Rampage II Extreme is not able to unlock:
- DRAM multipliers other than 1:3 and 1:4
- QPI transfer rate
- Uncore frequency
From other messages also P6T family has same locks.
A Gigabyte user assures HERE that in his motherboard above settings are all unlocked.
I hope that every overclocker that has a Xeon cpu will push Asus in any way to work on unlocking Xeon cpus.
Come on Asus, you can not be beaten by Gigabyte! ;)
Is this a retail or ES Xeon?
The ES Xeons have the QPI and Uncore locked, it's not ASUS's fault for those.
It is a retail W3520 that on Gigabyte motherboards seems unlocked, as says FragMagnet some messages above (LINK).Quote:

needless to say I'm happy :D I have some good baselines and bios profiles, and the lower ambient really wasn't needed. I just realized that it was a 2 Ghz o-clock !!
Frag,
You may not realize it, but I think you just set a new record, at least for this forum. 4557 Mhz is the highest sustained prime run I've ever seen in all the
i7 920 threads. It's all the more impressive given your high temps. By that, I mean the higher the temps, the better the AC characteristics have to be.
Way to go, man!
wow those D0 are very impressive....you guys convinced me :yepp:
should i pay 377 of 920 or 400 for a W3520?
i mean is the 30 bucks worth it?
that's canadian money btw
Once I read this, I didn't even look at your settings or submissions for I already knew they were invalid. Run Prime95 Blend 30m - 1hour then resubmit. Try actually testing for VTT instead of just setting 1.35v thats WAY too high compared to respectable submissions.Quote:

Hey ben...
I've been skeptical on the D0 hype as most of the 920 stuff has been sweet regardless of stepping...
Look forward to you firing one up...

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:

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
http://bcphoto.org/misc/4.3htoff.jpg
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.

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:

Mr definition of stability over here might want to load up his bios, choose load fail safe defaults and put his tinfoil hat on. If you want true stability you should have gone with a workstation board and no overclocking. :up:

So lets look at it in a way that is rare in this world, objectively. You are overclocking. Overclocking itself is a singular variable of change. I'm not going to bring in the scientific method here so lets latch on to the concept of changing variables. Encapsulated in overclocking is a plethora of variables that only further add to the analysis for stability.
What does all this mean? Unless you hit default settings and go back to square one your idea of stability will never be concrete. Is the earth's environment stable? Hey we are breathing and living right so it is stable. We apply an exponential amount of chemicals into this environment, similar to stressing the environment, and we are still living right? While that may be stable to some, it certainly may not be stable to others.
Now that the the arbitrary argument is defined here comes the objective viewpoint. We have a set of tools that are mathmatically based; there is no stress component type software. But do you have any other tools all of you stability wiseguys?
You use what you have and test accordingly. You have the next best thing so use it. Linx for i7 has been proven to be more stressful on the new architecture. Use it. Simple, done, nothing more to say. To argue otherwise is just going to have you running in a circle with your head down until you finally stick it up your own ***.
Hey man, is that much QPI/VTT necessary?Quote:

So there is no validity in claiming "stability" just because your CPU has run 100 passes of linpack because another program might cause your computer to crash.

The good news is my DS4 is one rock solid board. All other voltages are at stock(even QPI) and there is absolutely no vdroop! :)

Did anyone test this with another Board?Quote:

Anyhow, looks like you've got a lot of headroom left, could validate well above 4.7G with more
voltage. Great job!

I can pass 50 passes of linpack on a P4, at a certain speed, but run a 2D directdraw game (like Maplestory) or a 3D game (both which cause far less stress on the CPU) and the computer will bluescreen in less than 30 minutes, if the vcore is too low.
Haven't seen this happen on core2 architecture.
Taking RAM or chipset stability issues out of the picture, you never know what can cause a flip-flop to fail if you are on the edge of stability. Sometimes the strangest combination of transactions can cause a failure.
20 minutes of linpack plus a battery of other tests is a good way to get a well rounded result, though.
