A 3.6Ghz quad will get HOT on an CNPS9700 - that's a lot of power running through a CPU.

Maybe my gpus overheated??? (still on stock cooling - no overclocking)
But it happened...and thats all I can say.Quote:
A reasonable possibility some GPUs overheat quite a bit and could crash. Also drivers and software conflicts can also cause a crash.
Quote:
I'm not saying you shouldn't run a proper stress test, but you should run BOTH. Orthos alone isn't sufficient
Again, there is nothing that one can do under normal operating conditions except folding that could produce enough stress to crash a system where Orthos failed.
BTW, Orthoe uses Prime95 to stress test so prime 95 and Orthos are more or less equally stressful to ones system. The reason that I request Orthos is because it also shows processor speed.

I don't think you will have the heat problems that others seem to think you will. the zalman CNPS9700 is a very good cpu hsf and not that far below a TR U120E.

thanks!
i appreciate the kind words!

btw, does anyone do folding@home here? wanna join my team?
As of now, i have about 60Ghz of CPU power dedicated to Folding@Home :-O

Imran, your computer probably crashed because your GPU was the one that went unstable. Seriously, no game is going to stress the CPU more than Prime 95.
Get ATI Tool and run the artifact scanner to stress test your GPU.

-im1992
This is very common, because a lot of these synthetic benchmarking apps test only a few key areas of our system. We can run a few apps to cover but may still leave a few things out. A big one so often overlooked and not often tested for its stability is the SB and other aspects of the storage sub systems such as RAID AHCI and or just plain old EIDE or ATAPI controllers as well as USB oand other system bus devices when put into the real world function. They have to be expected to work all at the same time as some given point, even if only for 3 secs.
aMD's "Cool And Quiet" is just their version of Intels "P" state control and this is why it is not so stable and less so on an AMD system since it is also NB chipset based and both BIOS and CPU controlled. After a certain OC level, the system can no longer keep up and remain stable. This is why ASUS and most other mobo makers now disable this (EIST) automatically as soon as you OC. ASUS used to allow OC to a certain FSB then cut off EIST.
C1E+TM is the few of these "C" or "P" state features that can be used i an OC'd system for at least the "C" states side of it. This reason is because as we OC a CPU beyond a certain FSB level, the "P" state values may not be good enough to keep stable.
On mobos that actually allow EIST to be enabled during an OC, or for stock users, use one or the other of "EIST" or C1E+TM2/TM1. They are competing to try to do a similar job and are only gonna' cause a slight lag in performance. For a OC'd system, it gets worse, it may freez and or crash during the struggle.
Oh ja, cool beens ons on the Q6700. If you duct the fresh cold A/C air in, be sure to get the exhausted case heated air out just as good. As long as you're using the window A/C, utilize its return intake to do this so the room doesnt take in all the heat of the system. Believe me, even my water cooled units heat up an average sized 12x12' office in a matter of an hour or so if I dont sent that exhausted air somewhere else.
As for your CNPS9700, I agree, you are still above average what most are using. It comes somewhat closer to the ThermalRight Ultra-90 of a single average fan.

True, but those areas include CPU, memory, chipsets, and FSB, and by their very nature all forms of PC operations are synthetic since they are all in the digital domain. Prime95 was never intended to be a stress testing application when it was first developed it is an application looking for Mersenne primes (really large primes). That is no more a synthetic application than gaming or DVD compression. The great thing about Prime95 is that it's really looking for data corruption, errors. Prime95 doesn't just stress a system looking for heat until it crashes it also stops when the smallest errors are reported.
If Prime95 ignored errors than a large number of failed systems would just roll on cranking out errors hour after hour. People with high overclocks who don't stress test their rigs can't be certain if their rigs are producing errors or not, and often they don't find out until their systems data is corrupted beyond recovery. This means that everything that is in main memory or is being written back to the hard drive could contain errors, and errors.
Prime95 should be ran more than once (I ran it twice} with a least one run of Short FFTs. Now its true that some computers that pass prime95 might crash performing a different set of tasks such as folding or playing a very graphically demanding game. When I was beta testing for FAH@home there were some teams complaining about not receiving points for completed Gromacs, only to be given the message that their Gromacs were corrupted. It is possible for a prime stable system to crash when playing a game because ones graphics card might fail through over heating, but Graphics card weren't designed to work with data.

Indeed, I'm pretty sure there were comments about folding at home causing errors when all was well with Orthos and OCCT. You just have to keep your eyes open when overclocking, in all areas. As for the CNPS9700, I'm not putting it down as a cooler, but even an Ultra-120 gets very hot when you run a 3.6Ghz quad with one, so a CNPS9700 will also get hot.

For how long? Let's see, run ATiTool for 45 mins, WHILE running Prime95 for 45 mins. Then run Mass Effect and see if it goes unstable.

True, and that's one of the reasons that Donald (64026402) and I promoted it as a test for computer stability. Like Pime95, it crunches some hard data, and also like Prime95 it is not a synthetic test in the sense that it has a purpose. That doesn't mean that synthetic tests don't have a purpose, I use them all the time in early testing, but then it all comes down to how accurately does it handle data. It's possible to build a system that appears to be functionally running fine but if it is writing corrupted data back to your hard drive, it will fail, but before it does you will have noticed a progressive quirky behavior.
ATItools is meant to find the functional limits of ones graphics card's GPU while overclocking, it does very little to stress the main parts of ones system such as CPU, chipsets, and memory which are the real keys to finding stability. Get those right and everything else can be easily replaced.

As you may remember I had that very problem with my D-940. It ran beautifully at 3.84gHz, it just wouldn't complete the WUs, folding! It did start getting flaky and I finally had a non-temperature related crash while running DVDRB/CCE I had to drop my OC to 3.71GHz, where it worked fine once I did a fresh install of XP-Pro!

I do indeed! At first I thought that you were just trying a new method of fusion reaction.;)
There are so many high overclockers out there, and I have nothing against it. I'm one, for a few minutes or just long enough to take a few benches, but I also admit it. I like hitting unrealistically high overclock numbers for fun, but I know enough not to leave things like that and expect consistent results. What bothers me is that so many newbies see all this as a reality, and if no one tells them otherwise then they are often left chasing smoke and mirrors.

"Fusion Reaction"! Yeah, I did let the smoke out! LOL!! I still can't find a thing wrong with that MB. nothing burned or discolored, it just doesn't work!
As far as the "What bothers me is that so many newbies see all this as a reality, and if no one tells them otherwise then they are often left chasing smoke and mirrors". Oh, you can tell them otherwise, but most don't listen! LOL!! They get the distinct attitude that if Tom's or Anandtech can do it, so can I! They seem to think it's Gospel! We had one guy here that went straight to 4.0GHz, right out of the box. He was lucky! He didn't blow it up! LOL!! What bothers me the most is this all sets a standard for others to follow and do the same thing. A dangerous practice, in my eyes!

I've learned a LITTLE bit while on these adventures!
NuckNFuts is our resident EXTREME overclocker, but back when I first got my E6750 I took it straight to 3.6ghz and I kept it there. In fact I tried 4Ghz but my memory was crappy(Crucial Ballistix, even though in the computer I had before that one the same memory could do more than 1066Mhz).
Like I said I have gotten a bit better than that. I have built about 15 computers so far, and you learn some from that.

Not a bad start, a lot of people in forums give advice without having built a singe computer. They're great at Googling but they often lack the experience to fully understand what it is that they're reading. I'm a big supporter of overclocking because it allows industrious and creative individuals to extract greater value from their purchases. I began overclocking about 14 years ago and in those days it was all done with pliers and pulling pins, and guess work. There were no settings in the bios to adjust Vcore, memory voltages,FSB, or any of the adjustments available today. Thank heavens for that. LOL
Tom's Hardware grew out of that and became a great place for groups of us to share our experiences, compare our overclocks and learn.
Below is two quotes from Tom Pabsts who started Tom's Hardware. Remember that some of the statements regarding temps are now dated, but thes essence remains true.
Quote:
"Nobody likes system crashes or hangs, but in a professional business environment, avoiding a system crash or hang can be most crucial. It certainly is a fact that you are increasing the probability of system faults by overclocking your CPU. But it is only a probability! If you have just overclocked your system and the first thing you do is use it to start writing your dissertation, don't be surprised if a system crash occurs which causes you to lose all your data. After finishing the overclocking process you have to put your system through a tough and thorough testing procedure. If the system passes all the testing, only then can you talk of successful overclocking and feel confident that everything is working well."
Quote:
"Electromigration takes place on the actual silicon chip of your CPU, in areas that operate at a very high temperature, and can cause permanent damage to the chip. Before you start to panic, you should first realize a few things. CPUs are designed to run at temperatures between -25 and 80 degrees Celsius. To give you an idea, 80 degrees Celsius is a temperature that nobody is able to touch for longer than 1/10 second. I have never come across a CPU at this temperature. There are plenty of ways to keep the CPU case at less than 50 degrees Celsius, which increases the probability of keeping the chip inside at less than 80 degrees. Also, electromigration does not immediately damage your chip. It is a slow process, which more or less shortens the life span of a CPU running at a very high temperature. A normal CPU is meant to live for about ten years. However, in ten years nobody is going to be using a CPU with today's technology. I won't even use my CPU anymore in 2 months. If you want to be kept free from this electromigration scare, you have to do as much as possible to cool the CPU. Cooling is the Numero Uno Oncho in overclocking! Never ever forget that!"
