Is 15hr 30mins of Orthos enough

[Daver69]

Hi All,

Just built my new E6300 system consistong of the following

E6300@3.15Ghz 7x450 @ 1.35v
Asus P5B-Deluxe Wi-Fi
Geil Ultra PC6400 @ 900Mhz 4-4-4-12, @2.3v
Antec True-Control 550 with 20Pin ATX to 24 Pin ATX Adaptor
Nvidia 512Mb GTO (MSI) @ 700mhz Core/ 800Mhz Memory
Various SATA Hdd's and DVD-RW
Audigy 2 S/Card as the onboard was not that good.

I have never benched with Orthos and found Prime to be Un-Relaible on my machines.

I have been running prime for 15hrs 30+ mins with 2 of them running together and after 15hrs 30 mins one of the running Orthos failed, is this stable enough?

I have a thermaltake Bigwater Kit on my CPU, with my CPU ideling between 37 and 41, but on full loads with 2 instances of Orthos running and Super PI running it jumps up to between 60-63 is this normal as to the touch my CPU Block is pretty cool and the pipes form the outlet side of the block are pretty cool also.


I have had the system running at 500Mhz see screenie (7x465) below but it would run the likes of 3DMARK2006 and SuperPi but would not run Prime, but seemed pretty stable in windows.

Do I really need Prime to be stable?

thanks

Yes, you really need Prime and Orthos to be stable. You need them to be stable when running them under Blend mode. If they aren't stable, you will have problems, period. You need to raise your RAM timings to 5-5-5-15 to start with. Chances are very good that at 5-5-5-15, you'll pass everything, including Orthos Blend.

Hi Myocardia,

thanks for the info, had the memory timing running at 5-5-5-15 and really did not make any difference. I also ran memtest and the ram was fine at these speed, used to work for Micron before they closed the Scotland Op's in Engineering Dept

One thing I have really noticed and I had this on my OC Opteron sysytem is that it ran 24/7 like my new rig and never crashed, never BSOD, once I had found the CPU limits but it would not pass Prime Either. Strange as it would pass everything else I threw at it.

I was being lazy with the screenshot as I deleted it form my machine, so I just done a copy form a previoe post elsewhere Just added direct link to the picture now.

With 2 instances of Orthos running for 15+ hours each I think it is a Thermal issue and my Watercooling may require upgrading to get that CPU below 60 at full load.
Not very keen on 60+ temps in my machine. Running a lot cooler this morning right enough as we have some nice chilled air coming in through the window sthis morning here in Scotland. Idling normally 40-41 now 36 fair old difference just with some fresh air. Roll on the winter

I will go mess around again and keep you posted

thanks

Daver

I know alotta people here are hardcore stresstesters, but 15 hrs. lol?

I'd say that's perfectly fine.

You can run everything 24/7 with Orthos failing within minutes...not that i'd recommend it.
But i did that with my previous sytem & never had any issues for gaming & re-encoding video...& i mean encoding not just transcoding.

 

[Captante]

Prime 95 has given me some weird problems on the last couple systems I've built, both AM2 A64's with Nforce 590 SLI mb's ... it will start running normally & then sit there on the first test. No errors, it just seems to run very, very slowly & to suck up huge amounts of RAM for whatever reason, then it refused to properly exit when quitting the test.

Both these systems will run Orthos, Sandra, Memtest etc for literally days without any problems, so at thais point I'm not convinced either has a hardware problem, but rather I think theres a bug in the newest versions of Prime 95 involving Nvidia 500 seris motherboards.

 

[nyker96]

I'd say that's plenty unless your rig is set to run 24/7 in that case it's not enough. You need to run it pass the normal period of time you usually use your machines.

I wouldn't go as far as to say you don't need both Orthos and Prime95, but I would be damned confident with 15 hours of Orthos or Prime95!

OP, your VCore is too low for the O/C you got. These mobos are known for VCore drop,
try 1.375V Core (or 1.40V), it should do the trick for you.

Also at this FSB speed, bump Vmch up 0.1V or 0.15V for a 24/7 stable operation.

 

[Daver69]

Madellga,

What I am finding the more volts I am giving the CPU the more heat and the less reliable the CPU is, when I took the board to 7x500mhz I only had in the bios 1.35 Vcore and it ran quite a few test without issue. I have backed the CPU down to 7x430 just slightly over 3ghz until I build a new Water-Coooling Set-up and it is running dual Orthos stable 24/7 along with super Pi and 3dmark2006 at the same time

I am happy at the moment, when I get more time I will try to go for the 500+ again.

Sometimes Some Cpu's and memory respond better to lower volts and I know this as I worked in the Engineering Dept for the likes of HP, Compaq and more recently Micron

Cheers
Dave

actually I've had a system that has been running 24/7 for over a year and it fails blend in 5 minutes. Never a crash, error, freeze, stutter, jitter, or BSOD ever.

I'm having just the opposite problem -

Passed 3 loops of memtest - zero errors
Passed 5 hours of stress prime, blend and cpu - zero errors, zero warnings

Lots of BSoD lately, but I think I've narrowed it down to the sound card drivers - driver irql not less or equal to, accompanied by static and looping sounds, etc.

Everyday usage differs from stressing the CPU and memory like Orthos can do. That's why I don't put all my faith into Orthos or any test. I do a bit of gaming, 3dmark tests, orthos smallfft, memtest and see then if it all works ok. I've seen a system pass orthos 24hours and 3dmark crashes. Up the vcore and you get through 3dmark.

 

[MADMAX23]

Madellga, My 6400 is running at 3.2Ghz with only 1.280 on air....and it's 12 hours stable under Prime95 or ORTHOS.....so figure out...Now I'm testing 3.6Ghz (450x8)....it has already passed the 6 hours barrier with success under Orthos Small FFts test with a Vcore of 1.460v...if it passes succesfully 12 hours...I'll stick with these settings and I'll let all of you guys know...

 

[akshayt]

IMO just run a few intensive games like Oblivion etc for maybe half an hour each, run all 3D Marks, that should do. If you want you can also run super pi and occt.

In my case it was bad creative drivers... I installed their web update and it messed up the IRQ addressing somehow. After uninstalling and re-installing the CD drivers only, no more BSoD.

YOU BASTARD! HAHA Why must you insist on making me want more from my chip? What vcore are you using in BIOS?

Emmm.... firstly, be gentle. Secondly, wash your mouth. Thirdly, wretched chip? you don't know what you are talking about, do you?

I do still recommend you and everybody to stay at 400 FSB x 8 = 3200 Mhz, it's the sweet spot. Low voltage, a good chipset memory strap, nice memory performance then....it's the best option for 24/7 use. However, you (and me too, why the hell not?) can push your system more...memory performance will suffer until you pass 455-460 FSB but that's up to you. In my case, I just want to find my highest CPU stable OC at a Max voltage of 1.5v. What will I do when I find a MAX overall OC with nice performance? Use for benchmarking and ocasionally, for ex, when reencoding a DVD movie with Procoder 2.0...that kind of tasks, but not for 24/7 use, definitively not.

Right now I'm still testing 3.6Ghz at 1.460v (actual Vcore)...if it passes succesfully my tests, I'll go for 3.7Ghz and so on until I hit 1.5v...but that does not mean I will use that config (3.6 or 3.7 Ghz) for 24/7. I'll use it for benchmarking, not for 24/7, is it clear?

Think about the very first parragraph, body...forum users, including me, don't like that kind of guys here...

Oh wow, we have a winner here folks

I know what you mean and I agree also. The OCZ Plat I have can go all the way to FSB400, the secret is VDim 1.95V. A notch more and it fails, even stock speed.
I posted this finding on other threads and it helped some people with OCZ Plat

Same applies to VCore, I can also run 1.35V on Orthos for some hours but it doesn't complete 24 hours, unfortunately.
On the other side, increasing VCore helps to reach 3.4GHz or 3.6GHz and run somebenchmarks, but the extra heat output makes Orthos fail also.

In my case, 1.375V seems to be the sweet spot for both chips (E6400 and E6600).

The difference is that 1.375V on bios means less on the Gigabyte (VDrop) and a bit more on the Abit (Vbump).

Madmax, you have indeed a good C2D :beer:

I understand that more V is not always better and I try also to keep cool, quiet and safe.
50% o/c is good enough for me

Besides you, the other guy with an excellent C2D is Smokedog

Actually 15h is not that long. I regularly prime over 24h and also memtest. It does depend on your requirements. I don't just want stability I want a fairly high degree of reliability and accuracy (obviously not extremely high or I wouldn't be overclocking and would be using ECC). I want to know my system will be rather unlikely to ever have a calculation error or memory error. If my system is regularly unable to last 15h without an error then that simply is not met (N.B. you must remember here we're mostly talking about averages. You might get an error in 15h you might get one in 2h).

 

[Nil Einne]

Okay I admit I've never heard of Orthos before today (or perhaps I did but forgot) but I'm not particularly sure why people are saying Orthos and Prime should be stable. They should be stable. But when you say Orthos, do you mean this? http://sp2004.fre3.com/beta/beta2.htm

If so, as far as I can tell I don't see any particular reason why you need to test with Orthos & Prime95. Orthos is just a dualcore version of SP2004. SP2004 is basically just a fancier GUI for Prime95. I haven't read that much (I don't have a DC anyway) but you can either run Orthos or 2 instances of Prime95 with affinity set. Either way, it comes down to the same thing. If one is stable and one isn't either your doing something wrong OR there is some strange bug or version specific issue...

It could be a bug. But are you doing things right? I assume your talking dualcore otherwise no use running Orthos. I also assume your running 2 instances of Prime one for each core right? If you are, I do hope you don't just choose blend and be done with it. Blend uses about 80%? of your memory. Prime95 doesn't know or care you've got 2 instances running. It's still going to use 80% of your memory/instance. If you have 2 instances, you need to manually set it to use about 40% of your memory/instance. Anything else is going to cause major problems because your going to be trying to use the swap a lot. It may very well cause the symptoms you describe.
