I've managed to narrow down the problems I've been having with my new box. When it's booted cold, I'll have all kinds of programs segfault (I use Linux). Sometimes it's Firefox. Sometimes it's X itself. One time I even had a kernel panic. Once the system is warmed up, it becomes stable and works well. I've got an i5-750 with two sticks of 2GB Corsair value RAM. I've updated the BIOS to F5.
I tried boosting the QPI voltage to 1.25 and disabling the extra CPU stuff, but that didn't help. Here's what I did. Last night after a cold boot I ran Memtest86+ 4.00. After two passes, I got ~9 errors in the upper part of memory. I removed the stick from slot 3 and ran Memtest. Two passes, zero errors. So I put the other stick in slot 0. Two passes, zero errors. So I put there other stick back in (that meant that they were in the opposite slot they started out in). Two passes, zero errors. Figuring it might have warmed up enough to be stable, I powered down.
This morning I ran Memtest first thing with the memory in the same configuration that had given no errors. This morning, it's throwing a ton of errors, once again in the upper part of memory. Same general addresses. I'm on my fifth pass and it's gotten over 180 errors, most of them on test #7, but also a couple on test #5.
If anyone can make heads or tails of this, I'd appreciate it. I bought the system from CyberpowerPC and am awaiting a return call from a tech.
