OCing an E8400 with a GA-X48-DS5 Mobo.

Hi, I've taken Jsc's advice and started a new thread regarding my issue with OCing. I have a E8400 A stepping E0 Rev installed in a GA-X48-DS5 Motherboard and my other hardware is a Cooler Master 600w SilentPro M600 PSU, 2x 2gb corsair xms2 ddr2 800mhz memory and a CPU cooler (I forget the brand) and I'm trying to make a stable 4.0ghz OC but I've been running into a few issues that I'm just not experienced enough to deal with yet (only been OCing for a year or so) here's my default mobo f7 bios settings (which run at 35c idle and 45c load):

I've ran Orthos with the above settings for 8 hours and it ran stable with temps not going over 51c but I feel as tho my ram is a bottleneck and I'm not sure if it's the settings I chose regarding memory or if it's the ram itself but I may just be paranoid.

If anyone could see any problems or has any advice on what I should change it would be appreciated.

Im confused. You are stable? So what is the problem? Mine is almost identical ( 450 FSB ) and I run a bit cooler but I have a different cooler. You just trying to go faster? Try raising the RAM voltage to 2.1.

Honestly anything over 3.6ghz basically gets the most out of the chip. 4.0ghz is just icing on the cake. Everything looks great to me.

HI. I am back. See how much easier it is when you have your own thread?

If your goal is 4.0 GHz, you are done. About the only things I would do is reenable EIST (SpeedStep) now that your OC settings are stable and turn on the CPU Fan Fail Warning.

If you want to see how far you can go, increase the RAM voltage + .3 volts to 2.1 volts and increase vcore to 1.4 - 1.45 volts. Then increase the FSB freq until the OC fails.
