    Default OC setting help for Q9550 EP-45 and OCZ memory

    Hey all,
    Im good with computers (every aspect but overclocking/bios changes) and finished putting together my newest pc a few days ago. I've been looking around all over the web trying to find the most stable bios settings to run at 3.6-3.7 ghz and finding some differences (either in settings or they have different memory/ghz outcomes). So I have yet to input anyones settings. Here is what I got
    -Gigabyte EP45-UD3P motherboard
    -POWERCOLOR AX4850 512MD3-DH Radeon HD 256bit PCI Express 2.0 video card
    -Intel Q9550 2.83 GHZ processor
    -OCZ Reaper HPC 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory
    -1 tb Western digital caviar black 7200rpm sata hard drive
    -OCZ OCZ700MXSP 700W power supply
    -Sunbeam CR-CCTF 120mm "Core Contact Freezer" CPU Cooler (was fun to install...by fun i mean worst experience ever)
    -Windows XP sp3 os
    If someone can share all their settings that are stable or help me weed through the wide range of shared settings online that would be greatly appreciated as I don't want to change anything in the bios unless i know its proven. Thanks,

    Thank you to the max , before I try these i want to confirm that the 4 vs 8gb memory difference and os difference won't affect the results.

    I am using 8GB and I believe the only real difference is that you do not need as much voltage to the memory. I am not overclocking my memory so the settings will not effect it.

    Thanks again Xevius. I tried those settings and the pc kept rebooting without starting up (it was 3.83 ghz) and i dropped it down to 3.67ghz and it's stable now. Im currently running Prime95 blend test for just over an hour and the highest cpu temp so far is 64 degrees, system temp 39 degrees. This is a little warmer than i would like as I would like to try keeping it under 60 degrees max load, what would you suggest I change to lower it without dropping the speed?

    I left Prime95 on overnight (7+ hours) and when i woke up my computer still worked :) the results were good since there were no problems or errors. I just want to drop the temps a little
