I have a Biostar motherboard with the nforce 2 chipset. I also, untill recently, had 3 X 256MB sticks of DDR memory. 2 of them were running in dual channel, and the other was just extra memory I suppose. Well, all of a sudden I start getting random reboots, then not so random..... my computer would boot up fine, but when I'd load up a web page, and use the mouse scroll wheel, or click on a link, my computer would instantly reboot, and sometime give me a mem dump error.
So I decided to run Memtest-86, and btw, I ran it when I first installed the memory and it passed fine. Now it always locks up sometime soon into Test #6. Prior to Test #6 it has zero errors. I decided to test each individual memory stick in each of the 3 memory slots on the motherboard. By themselves, they all run fine, they make it through a full pass or 2 of Memtest without problems. But soon as I try to run any of them in dual-channel mode, I get the lock-ups and the failed Memtest.
2 of them were a 512MB DDR kit of Kingston memory, so they're matched and supposed to run dual-channel. The 3rd is a single stick of Crucial.
To add, I currently have the 3rd slot or the 2nd half of the dual-channel slot empty. And I have the First 2 slots closest to the CPU filled with the Kingston units and they together pass memtest fine with no crashes (in non dual-channel configuration).
So given the above info, does this sound like a faulty motherboard, or faulty memory or ? If anybody has any experience with a problem like this, or any ideas, please, I'd love to hear about it, thanks a lot =)
