stability help

[sanitydc]

not sure if theres a sticky for this so apologies in advance.



alright, so I'm running the e6400 ds3 combo.
i have it OC'ed to 3432 mhz there abouts, (429x8). I have adjusted the voltage the vdimm and the mch as I have OCZ2P8001G and it requires 2.1v as I understand it, so that's at +3 mch at +3 as well and my vcore is at 1.408 according to everest ultimate however I have it set to 1.437 in bios (i think) the one immediately above 1.425 it may be 1.432. and my ram timings are 5-4-5-15.
new heres the issue, every stability and stress test I give this thing it passes, except orthos.

I know others that have OCZ ram have experienced difficulties as well but I'm wondering if any of you have any insight into that?

my stability test passes:
dual 32m superpi with and w/o affinities.
dual prime 95 w affinities for 1 hour (then turned off because i was bored)
everest ultimate stess test
orthos gromacs (20 minutes then bored)
3dmark06
pcmark05
3dmark03
crystalmark

eh, there may be more that's just all I have ss'ed. oh and can someone link me to the superpi that your forum members use? mine measures in seconds not ms's.
oh yeah I'll provide any ss's if it will help you help me out.


thanks very much I appreciate any help you can offer me.

Here's how overclocking works: if there is any software that you can't run, that will run at stock speeds, then your overclock isn't stable, period. See if it will pass Orthos at 400x8. If it will, then see if it will pass at 410 or 415x8.

Also, out of all of the software that you mentioned, none of them stress the RAM, unless you ran Prime95 in blend mode, except the Orthos blend test. Raise your memory timings, and see if it passes the blend test. And by pass, I don't mean for 30 minutes to an hour, or until you get bored. Generally, 8 hours is the minimum that's considered "stable" by any overclocker.

seems bs'y that it would pass prime95 and not orthos theyre nearly the same test.

Not if you run them with different settings, i.e. with small fft's on Prime95, and Blend on Orthos.

i agree with myocardia

i've run a cpu with largefft for 13 hours and then ran smallfft and it errored out in 5 seconds.

I bet you anything that if you back down a little on the OC, it will suddenly "become" Orthos stable

this post is a lil outdated but after I updated to f6 I passed for about 30 minutes and gave myself the all clear. lol I duno if you guys are rich or not but 8 hours of 100%cpu is prolly like 30 bucks on the power bill..

my power bill is $450 a month and it doesn't suddenly jump to $500 because I start testing a new overclock and running D2OL alot.

you don't think so? seems like 12 hours of probably 150 watts constant + what ever else is goin on would do some damage.

150watts? what? You never get max load really ever.
