I put together this dual-core system, and it can run SuperPi fine, but as soon as I start a calculation in a second SuperPi instance, the second calculation almost INSTANTLY errors out saying ""NOT CONVERGENT IN SQR05". I haven't attempted to overclock anything.

Any ideas?

Core2Duo E6600 (2.4 GHz 4 MB shared cache)

Thermaltake Big Typhoon

Asus P5B Deluxe motherboard

2x1GB OCZ DDR2/800 (PC6400) 4-4-4-15

Antec 900 case

Antec Phantom 500 power supply

ATI Radeon X800

2 x 400 MB Seagate SATA/2 HD's

Samsung DVD combo drive

Floppy disk

i should most honestly hope that you mean 400GB drives in there. [everyone makes typos]

the OS, i should assume its Windows XP, although, if it is Vista [as some use it heavily] it may be the fact that Vista is not completed yet, and may not be able to.

well thats odd.

try using orthos, its a version of prime95 that tests both cores at the same time. personally i could care less about superpi.

For AMD cpu's but might have some helpful information.

Since this is a new build and all... Have you checked in the BIOS to be sure that the RAM and CPU are running at the recommended voltages?

Thanks for the suggestions. Orthos sounds interesting. Memtest works fine on my PC, but I've seen it work on exremely unstable PC's before. Two instances of Prime95 work but they make a 2.5 GB pagefile so they seem to test the disks more than anything else.

Hahahaha.. I'm a total n00b. Two superpis run from the same place cause the same error on my other single core PC. But when run from different directories, no error occurs.

So my Pc is stable AFAIK. And I actually have Radeon X1800 XL and my two 400 GB disks form a raid 0 volume. It rocks so far!

haha, i forgot about that, that happened to me too a while back.
