View Full Version : How can Orthos run for an hour if Prim95 fails after a minute?

I picked up a Q6600 G0 yesterday and the thing sucks. I couldn't even get it stable at 2.8Ghz before adding the bios update, and even with that the thing is not stable.
Running at 3GHz I can run Orthos for over an hour, small FFTs on all four cores, but if I fire up Prime95 it errors out within a minute. How that be?
Wish my chip wasn't a piece of ****. I was running at 3.5Ghz with my dual.

That's a weird one.

You have to use old bioses in order to achieve any sort of overclock with the 600-series of chipsets. :) Believe me intel's quad cores just don't mix with nvidia chipsets. :-/ Mine's perfectly stable at 3Ghz, but anything over that and it becomes unstable...(you could also try lowering the multi to 8x to see if there are any fsb holes - 450x8 is the only way for me to reach 3,6Ghz, but requires a lot of juice! Kind of wish I had gone for an intel based mobo instead.... 400-450 fsb won't boot for me and even 3ghz was unreachable on newer bioses.

The quad cores don't mix well with the 680i nVidia boards. The 680i works very well with the new 45nm dual cores though. I have an e8400 @ 4050MHz on my AR revision eVGA 680i with the p32 BIOS. I'm holding off on quad core until Nehalem with it being a true native quad core CPU. That and there are only a handful of games that actually use more than 2 cores, so to have a dual core a 4GHz+ gives me far better gaming performance than a quad core at around 3GHz.
Probably because Prime95 stresses your memory subsystem more than Orthos does, especially if you run the blend test. What is the version of your EVGA 680i? I heard you need the A1 version for the quad cores to OC well. Anywho, try increae your north bridge voltage a bit and see if it helps.

I don't have the A1 revision unfortunatly. Guess I'm out of luck unless I want to get a new board.

they gave new boards to people who wanted to OC their quad core . . . you just had to prove you had a quad core and that was a valid RMA reason

yah just call em up. iirc they even paid for the shipping, at least they did for my friend. (both ways)

Holy crap that's some good service for ya! Too bad I don't live in the states.... :thumbdwn: Evga sure are nice! Wonder if their support in Europe is as good as the one you have there?
It'll be the mobo, dude. 680i's differ hugely with OCing quads. I couldn't OC at all with an ABIT IN9-MAX mobo I had. The Striker was a little better at 3.0 Ghz.

To answer your first question, you probably have the newest version of Prime and an older version of Orthos so it doesnt have the updated version of "prime" built into it yet. Prime seems to be more effeicent.
Good luck on the mobo
I have a 780 sitting on my desk that I am pretty sure I will be disapointed with when I try OC'ing my q6600 compared to my p5k-deluxe (P35)

Get rid of that POS 680i.
Problem solved.

Well first - Vista has issues. I can orthos for hours with my new E8400 @ 4.1 Ghz, however Vista will instantly crash on boot up. Same PC I have 2 HDs one with XP install, the other with Vista x64 SP1. Orthos doesn't work properly under Vista.
It really seems like max overclocks are severely limited with Vista however. Now my quad doesn't suffer the same fate. 3.6 @ 1.44v is rock stable in both. Maybe Vista just doesn't like an E8400 for some reason. I game, orthos, memtest all perfect with the chip @ 4.1Ghz. But boot into Vista and it's BSOD after BSOD. The OS is just too beta even with SP1.
Until you lock down your stability, stick with XP, otherwise you are chasing OS ghosts with Vista.
Nvidia chipsets are junk
Prime95 > Orthos for stability testing

1. Agreed.
2. Orthos is Prime95 with a GUI interface. So Orthos = Prime95.

Actually, no. Prime95 stresses higher than Orthos, a 12W higher max power draw, and better OS scheduling as well. The latest versions Prime95 automatically scales according to the number of cores. Orthos however uses old Prime95 algorithm that will not give accurate result on Core 2, especially quads.
ok Your mobo's **** we all know that I had the same problem trying to hold 3GHz on a A1 version. I got a P5K Deluxe and I hold 3.6 easy :p As for Orthos you guys are idiots Grab OCCT wtf is with you damn Orthos whores?!?!?
I like both OCCT and Prime95, in fact I use both. :) OCCT for memory and NB stress, Prime for CPU. Orthos is completely useless to me.

Orthos just doesn't work for quads yet. However, it's fine on duals.
Orthos isn't a different program, just doesn't use the latest build of Prime that can run 4 threads - Orthos is just a gui lol, not a different app.
Summary
Stress Prime 2004 is a better, I hope, GUI interface to Prime95's Torture Test. Thanks go to the Prime95 people for providing the Prime95 source code (version 24.14).

30 mins isn't nearly enough to declare an OC stable.
