E8400 and Asus P5B overclock

post #1 of 4
Thread Starter 
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 :-)

you should be able to push 4.0ghz with that cpu. i'd bump your nb voltage a little bit. when i had my p5n-e i believe it was at 1.39.. different board i know but just saying. and actually i was able to get a 1000htz on my ram somehow.. but im gonna be honest.. i started bf3 with a e8400 just like you, upgraded to a q6600, and finally purchased a new rig with a 2500k. single player is ok with dual core, but on the big maps even a q6600 at 3.5ghz wasnt able to hold 45+ fps at all times.

You probably need to bump up your cpu voltage to help with the overclock. The pictures shows it at 1.3v. I think I used to run mine at like 1.35v or 1.4v with a 3.98 OC.
Yes your memory speed will change while you overclock.
Your memory timing, and voltage may need adjusting to make the overclock stable.

so small update here, following the guidence of some forums....I am stable at 3.8ghz.

My CPU Frequency is still 432.
DDR2 is 846mhz.
CPU Vcore is 1.35V
North Bridge Vcore is 1.40V


I didnt change anything else with the bios, and I can run though 30 min of Prime95 without errors so it's a lot more stable then before.

My problem is, I tried to go to 445 CPU frequency (445x9=4005) and I set the CPU Vcore to 1.40...windows loads but MSI Afterburner can't see my graphics card and my windows AERO is disabled.

Would this be a sign my video card isn't getting as much power as it should to perform?
