I tried setting my RAM to spec on my new system and had a "bad overclock". I got a blue error screen and couldn't get into Windows. Can someone help me figure out what went wrong? On "Auto", things were showing up as 8-8-8-20. I changed the voltage and the speed and manually set the first 4 timings to 8-8-8-21, but something went wrong. Did I change something I shouldn't have in the bios?

My build:
CPU: Intel Core i7 920
mobo: ASUS P6T LGA 1366 Intel X58 ATX

Oops.. subject should be P6T not P67. (typo)

Here's more about my error and what I did:

(Possible clue: something in my bios mentions that the RAM speed on "locked" CPUs may have limited options??)

I had an error after making the changes, so I changed things back.
I switched the RAM speed to 1600MHz and the voltage to 1.65v. Also, I changed the below timings from [Auto] to:

DRAM CAS# Latency -- 8
DRAM RAS# to CAS# Delay -- 8
DRAM RAS# PRE Time -- 8
DRAM RAS# ACT Time -- 21

(Did I switch the correct timings?)

The following timings I left alone, all on [Auto]:

DRAM RAS# to RAS# Delay
DRAM REF Cycle Time
DRAM WRITE REcovery Time
DRAM READ to PRE Time
DRAM FOUR ACT WIN Time
DRAM Back-To-Back CAS# Delay

What went wrong? I'm so stumped.

Anyone have a recommendation for a good place to get answers on this?
