Hey guys, I ran into a failure with Orthos. Was running my c2d 6400 at stock voltage but with 400fsb (3.2 ghz). I ran into failure at 35 minutes, so I upped it by one to 1.33 something and now it ran into problems earlier.

Since its a rounding problem I'm guessing its pertaining to the CPU, the load temps when I last checked was 56 degrees celcius which was a couple of seconds before the error popped up.

the memory I have at 800mhz dual channel with timings of 4-4-4-14 and voltage 2.1. The rated specs for this ram is 1066mhz with 5-5-5-15 and voltage 2.2. Ran memtest a couple passes and they were fine and dandy.

Any suggestions please! (my specs are in my sig)

well you should really narrow it down as it could be the memory or the cpu, the error message doesnt always give a clear picture.

you could drop the multiplyer to 7x and then run orthos again. if you dont get an error then it was the cpu and so raise vcore a little and go back to 8x. if you get an error at 7x its the memory. if thats the case then increase volts to 2.2V and try again.

of course you could just boot off a memtest86 floppy and check the memory will run those timings@ 400MHz 2.1V through a few full loops with no errors.

I usually run memtest86 ever overclock even if it doesnt pertain to memory overclocking. So I'm guessing it is the cpu. crap I liked the temps it was at....
 
I've heard of pi calculations being off if memory voltages were too high, or too low.
 
its the cpu, dropped the multi to a 7 and didnt touch anything else, booted perfect and ran orthos for about 50 minutes now and no errors what so ever.

So i upped the vcore and set the multi back to 8. Gonna run it for an hour or so, an hour of uptime is fine with me as all I do that is cpu intensive is encode videos :) (not a gamer)
 
thanks guys, my sweet spot is 1.34.....anything lower causes errors in orthos
 
Don't be so cheap with the voltage. The D9GMH memory chips hit peak performance at 2.4 volts and beyond so don't be afraid to give them 2.2 volts.

Even lower end memory continues to improve with more voltage.

You won't have any long term durability or heat issues if you boost your CPU up to 1.35 or 1.40 volts.

By only going up 0.01 volts on the CPU you might be Orthos stable today but a week or two from now it might get a little warmer out and all of a sudden Orthos will be crapping out and you'll be wondering why.
 
If memory serves, the Core2 chips won't start degrading until you pass 1.55 vCore.
