I have my rig OCed at 2.93 and raising it litle by little. my question is when i ran Orthos for stability test after starting it about less than a minute it gives me error and all i do is reset then run again and it runs fine. i had it running for about more than 11 hours with no errors. anyone experience this before?

thanks
 
I've never experienced that. However, I have had my OC settings to a point where Orthos will crap out after a few seconds, but everything else runs fine. I can run SuperPi, 3dmark, and play farcry and oblivion. The system is essentially stable. The only thing that craps out is Orthos.

Of course, I fixed that by upping the cpu voltage, and Orthos worked again overnight.
 
try increasing your cpu and your ram voltage just one more level above from where its at. i had this issue to where as soon as i start orthos it craps out on me. so what i did i raised my ram from 1.8 to 1.9v and now everything is all good.

thanks.. looks like that helps.. but another problem occurs but right after raising my FSB. trie d to go 3g and right now it's stable at 2.96. problem is it locks up when i run orthos. timing on my memory is stock cuz i have no clue about it. anyone knows what to do next to get it stable to 3g? see my specs on sig.. thanks
 
I am also a noob to OCing, but I can share what worked for me to get to my target OC. At first I did as you're doing, bumping things up and then tweaking at that level. I feel I wasted quite a bit of time going that route.

Turned out that this method was far more effective:
-bump up CPU and RAM voltages to the highest you think you want to run (and remember to closely monitor your temps throughout your OC process)
-plug in your final target FSB and drop your CPU multiplier to 6 in the BIOS and run Memtest86+ from CD (some people just loop test #5 over and over)
-if you fail memtest, your RAM voltage is likely too low for the FSB you're aiming for. This assumes your timings are loose enough and your target FSB doesn't exceed your RAMs rated speed (unless you've seen that others with your same type of RAM have been successful at your target FSB). Since you've maxed the voltage, you're left with upping the other voltages available (northbridge, vtt, southbridge), timing tweaks, BIOS options, or lowering your target FSB.
-if you pass memtest then bump your multi back where you want it and run orthos (small FFT to target CPU or blend for CPU & RAM).
-if you fail Orthos, you're again faced with upping other voltages, BIOS tweaks or lowering your target FSB.
-if you pass Orthos for your chosen duration (12-24 hours usually), you can now start lowering your voltages until errors reappear. Drop RAM voltage and CPU multi, then Memtest to find lowest RAM. Raise CPU multi then drop vcore to find lowest stable CPU voltage. Actually, I worked up from stock with the voltages after I knew what voltages got me to my target OC.

I'm quite sure there's more to it than my general outline, but it got me to where I wanted to be. Of course, I also combed many OC forums to pick up tips and the peculiarities of my MB, CPU and RAM. It helps greatly to see what people with similar or identical setups are able to achieve. OK, seasoned OCers...shred away!
 
What kind of ram do you have? 667/800/1066mhz?

If you're pushing the ram speed past the stock, then you'll probably want to loosen the ram timings (make them higher, which is slower)

For example, I have PC2-6400 ram that runs at 800mhz at 4-4-4-12 timings (check your manufacturer website for timings). I can run it up to about 850mhz at those timings before it gets unstable. I have to loosen the timings to 5-5-5-15 in order to go faster than 850mhz.
 
my MBs Multiplier is lock at 9 so can't mess with that one. i'm using Gskill ddr2 6400 but they're under clock at 667 because my MB (of course) is only rated up to 667. my timing are all in Auto and i have them at 1.9v. maybe i should just stay at 2.96 to be stable:( anyone else have any idea i would love to hear em.. thank you much for your help.
