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.

Well for starters I just wanted to make sure my settings were ok or if I should change some so I didn't hurt anything and I also wanted to know if my memory choice was ok for the rest of the hardware chosen or if I should upgrade it to like ddr2 1066 or ddr2 1200 or if it's possible to up the volts on my current memory and mess with the timing to cause it to run better without burning it out? Basically any advice on any possible changes I can make or if everything looks fine as it is. Thanks for the reply.

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.

I see, well, that's one opinion. Thanks for the reply. Any other opinions are welcomed.

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.

Thanks for the suggestions Jsc, they helped out and the OC feels much more stable and even raised my WEI score. I didn't go past 4ghz tho, I enjoy it enough as it is but I may test its limits in the future and I'll be sure to post my results with all the details.
