Ok guys how long running Orthos is considered stable? 2hrs+ or 12hrs+ I dont think im ever gonna have enough time to run it over a few hours. I do use my system for 3d Rendering and this absolutely Hammers your system.. but i doubt that counts for this chart

I dont understand this obsession that people have with Orthos 'deciding' that a system is stable or not !!! Not aimed at the poster, this is aimed at those that insist a machine isnt stable unless it can do 1 millions hours of Orthos, wile rendering video for 3 days, while doing bla blah blah for weeks ! ROfu - its upto you to decide if your machine is stable or not mate

As far as I'm concerned, if your PC can do hours of gaming, and doesnt crash while you use it, then surely that is stable ??? People have become a little bit too obsessed in these forums recently...if you check other forums, where the overclocking is a lot more hardcore than this one, they dont really give 2 hoots about bl00dy Orthos !!! LOL

I used to be very obsessed with stable this, stable that, but now I just enjoy the marvel that is the modern desktop computer. Its a lot more fun.

 

[ROfu]

yer but its a good guide to what is considered stable, i've never used orthos before personaly - like you i judge my machine on games and if it renders for 12hrs overnight (which it does for work regularly).. and still standing following morning.
But for the sakes of this thread, everyones throwing in thier clocks and showing what they have. Orthos seems to be the gauge of choice - hence my question.

I'm more than satisfied that my clock is solid, but theres nothing wrong with giving an app a blast while your computer has some downtime to meet the general requirements of the thread.

Gaming is also very subjective, as you could have a crash because of gfx driver issues, which have nothing to do with CPU stability.

While your applications may run fine, over time your HD's can become corrupted due to an instable overclock resulting in read/write errors and eventually terminal BSOD. If you re-install every month then you should be ok, personally I like to know my PC is stable for whatever task i may throw at it...and not go belly up 2,3,6 months down the line for the sake of an overnight orthos test. And those more 'xstreme' forums you are referring to run benchmarks, not stability programs - a world of difference between the two. Most here do not change cpu's every other month and use there pc's for more than benchmarking, advising people to 'run a few games and if it dosn't crash your fine is a little reckless imo. Its true that Prime stable can also crash in time but is an 'indication' of stability in its purest form - computations. If your computer cannot compute correctly then its little more than a 99p calculator(a broken one at that!).

 

[benktlottie]

Agreed to a certain extent. Just because its 12 hours Orthos stable doesnt mean to say that a build is guarenteed to last.

I have been overclocking for years, and have held benchmark records on various forums. I know a great deal about hardware and I consult during the day on hardware and software. Unless youre using a PC 24/7 doing in depth number crunching, which is mission critical, doing 12 hours of Orthos does not guarentee anything, it is only an 'indication' If the machine is that important, you dont overclock it anyway ! You could have your gleaming new machine, 12 hours Orthos stable, then bang. You install something that shags a virtual device driver, or corrupts a system file or say you get a power surge, and there goes your completely Orthos stable build.

I think that certain members of this forums install this fear into the less knowledgable that if your PC isnt Orthos stable, then you dont fit in, or your hardware is substandard.

This is nothing reckless in my comment that if games stable this is all that matters. If thats all you use your PC for, then thats all the stability that is required. If you can play Half Life 2, or that Battlefield games for 12 hours, then thats prtty much guarenteed to be a stable machine (as stable as any modern PC). I understand the read/write issues with unstable overclocks, but again there are various other reasons why this can happen, not just CPU instability.

I guess were all right in our own ways, and everyone has different opinions, but what I am trying to say is that Orthos isnt the be all and end all...

Oh, and the first rule of IT, make a back up ! If it all goes horrendously wrong, at least you can get your data back !

 

[ROfu]

well after 15hours 40min and 61 loops, it seems my system is quite solid. This is a nice "comfort" indicator, as this machine has been hammering away at 3d renders for 2 weeks now with no issues, but its always nice knowing in its purist form - the CPU and Ram are pretty solid.
I can see why orthos is used, its clean calculations mean nothing else is interfering with the stability test, no sound or Gfx interference.
Personaly i use 3dmark to test stability - if you can run that 5 times in a row with demo mode (so theres sound running too) then im satisfied, but after trying out orthos, i think ill be using it on any clean install even if only for a few hours.
I guess im gonna try out Prime next.

I just did a 24 hour orthos on a pc that i built 2 yrs ago with the old 3200 winnie and the dfi..... u all remember??

This was a very stable system for my kid’s room, playing games and other things... on the 22 hour it showed errors.

Here’s an other.. 17 hours

To answer your question,,, no time shows your system to be orthos stable. it only shows that your pc wont crash if you use it for a few hours. this also means that if your downloading films and music on a 24/7, this is hardly a stress for your chip, I don't think it would probably have a bead on.....

I have a feeling that your pc is ok if you have it on 24/7 for a few months without a restart. THIS IS A STABLE SYSTEM....ANYTHING OTHER IS BULL.

By the way, my record is 38 days, then got a power cut.. What’s yours??

whats with cpu stepping on here

cant you lot add the FPO/batch instead

the whole line makes things easyer for people

cheers

^^ load temps using Core Temp and Orthos?

40C load is hard to belive tbh, as I get 55C with Orthos in CoreTemp with a 15C air and a flat IHS and TT120 base

52C folding at home load

Oh yeah, I totally lied ! And I edited the screenshot with Photoshop. Hell, I dont even own a Conroe, or a PC for that matter. LOL

Seriously mate, when the TT arrived last night and I first fitted it, my temps were excatly the same as yours. So, I reseated it and used AS5 instead of the grease that came with the TT and put a 120mm fan next to it blowing across the base and RAM. I couldnt believe the difference it has made either, but it did. I watched every single second of that 32m run, and the temp hovered at 39 or 40 all the way through.

Just out of interest, what do you think I gain by lying ?

Not saying your lying, its just your temps are lower than mine with a higher ambient (most probably), higher clock and higher voltage.

Are you using CoreTemp to measure it or the asus software?

I CBA to run 32Mb Super Pi to see my temps, but you should try running Orthos for 10 mins, thats how I get my 55C CoreTemp load

I was using the ASUS temp software, and I am reporting what I see that display. Just for you though, I just downloaded Core Temp and ran Orthos as you suggested for approx 10 minutes. Asus showed between 43-45 degrees, and Core Temp displayed 47-49, so there was a 4 degree difference, and this remained consistant. My motherbaord temps reported 32 degrees without much fluctuation. BTW, how trust worthy is this Core Temp software ? It tells me that I'm running the processor @ 4.05ghz and the voltage is at 1.325 ! And thats not right....

I have one of these huge Lian-Li v2000 cases, which have great silent fans and fab airflow. Also, my Conroe is a week 28 (like yours, our batch are only a few apart), which are excellent clockers and are cooler at higher clock frequencies. Perhaps I used the exact coreect amount of thermal paste, and fitted the TT perfectly. I cannot explain why my temps are lower than yours ??? Every single setup is the same, and it is very unlikely you will get 2 identical temps at the same speed, volts etc. Perhaps I'm just lucky ?

I've been into extreme overclocking for a few years and have used phase, water and chilled water in previous setup. I must have fitted air coolers and the like a thousand times before. Perhaps I just have the knack mate ! I do get really good temps on all the processors I have ever owned.

BTW, you made me smile. You CBA to run Dual SuperPI 32m for 18 minutes, but youll run folding for 6 hours, and Orthos for 3 !!! Brilliant mate ! LOL

Hi, can I pick anyones brains as too what I am doing wrong here....
I've got a 6300 but the max stable overclock I can get is a FSB of 346 * 7. I'm running me ram at PC25300 with timing of 4 4 4 12, or 5 5 5 15 and a memory voltage of 1.9. Whatever I set the FSB too, be it 350, 360, and up to 430, I cannot get the PC to boot and I have to reset with the usual bios overclock failure message..
I'm using the newest bios 1503
I've tried to follow the settings that you guys have but nothing seems to work, my CPU isn't overheating and everything else seems fine and I can run the Orthos soak test with 346 * 7 until the cows come home.
Help me guys, as something ain't right here...

you may want to increase your DDR Voltage up to 2.1v which is what a lot of the DDR2 still is rated at. Mines at 2.15v 458 x 7.

Seems that the main reason people can get higher clock using chips above the 6300 is due to the x8 multi, i see a lot of people with lower ram speeds but with the extra multi they get a bit boost.
