Default E8400 and Asus P5B overclock

Hello everybody, I am new to the forum but not new to computers at all.

I would like to give a breakdown of my current system configuration.
-E8400 (Stepping E0 shown in Core Temp)
-6gb (4 sticks) ddr2 800mhz (kingston kvr800d2n5k2/4g)
-Asus P5B Motherboard
-Noctua NH-D14 HSF
-Nvidia Geforce 9800GT
-Cooler Master HAF 932
-Antec 850W PSU

My current temps on idle are about 28/29 celcius and within BF3 they hit about 39 degree celcius @ 3.0ghz

Now, what I have tried? Well I've been reading forum posts/threads/guides on overclocking and I think I am on the right track but I'm a bit lost and if anybody can point me in the right direction it would be greatly apprectiated :-)

The CPU is currently at 3.8ghz, windows works 'OK' but I was having a problem loading into BF3 today. I reset the motherboard back to factory settings and at 3.0ghz I loaded int BF3 no issues.
When I run Prime95 with it overclocked, it does give me an error within the first few min and stops the tests.

Here are what my bios configurations were:

One concern I do have is wit hthe DRAM frequency. Since my memory is DDR2 800mhz, when I set my CPU frequency to 423, my DRAM frequency jumps to DDR2-846MHz. So would that mean that my memory is working much harder then it would be at 800mhz??

I am not sure if I should be working on the NB/SB vcore's also.

Any suggestions/help/understanding would be great :-)

My System Specs


Drop your RAM down so its below 800Mhz, up the vcore to 1.4 and keep bumping up the FSB, stress test it for an hour or so in prime to make sure its stable, and repeat. Once you're at your desired clock speed try bringing down the VCore as much as you can while still being stable.
