I'm a novice when it comes to this area, so be gentle!
A new 2500K mini-ITX machine has been running smoothly for six days. It is using the Intel DH67CF board, inbuilt Sandy Bridge video, with 8 gigs of GSkill memory. Nice machine - Sata III SSD and a DVDRW drive all packed into a little Antec 310-150 case. Haven't gotten it above 109 watts out of the wall yet.
As I'd shelled out for premium 7-7-7-21 memory, and knowing that Sandy Bridge boards always default to 9-9-9-24, I decided the machine had proved its stability and it was time to dial in the "correct" settings. So I booted up, went into BIOS settings, and in the "performance" tab switched the memory out of automatic configuration mode and OK'ed the "are you sure" warning.
I changed the four settings in question to my intended values. I observed that the board was using 1.500 volts as expected. I saved the settings and rebooted, happily awaiting an even faster machine.
It was a disaster. The machine would light up and start spinning fans for a half second, power down, and repeat the process. Let's just say that neither the machine nor I were very happy campers.
I pulled the machine apart and pulled the memory, hoping I could boot up into the BIOS config screen, but it would simply give a beep code and not get that far. So I moved the BIOS jumper into the configuration position, and was able to come up. I changed the memory settings back to "Automatic" and saved those settings. I put everything back together and powered up without incident; I'm typing this post on the machine.
So the obvious question is: what don't I understand and what did I do wrong?
Thanks for any insight.
Art, very happy to have his machine back
