overclock my e8400...

post #1 of 21
Thread Starter 
haven't looked to much into it past this board but just wondering what is my safe limits to go with this chip. i have a p182 case with pretty good cooling and an artic cooler 7. I have heard to go to 9.5 multiplier and with a asus p5n-d mobo what is safe to increase the FSB to.

I know there is alot of people on this board with this setup so just wondering what everyelse is doing so i can skip the experimental steps and just get it running good.

Several things are in error with your post. First the E8400 has a 9X multi, not 9.5
Second every chip is different so asking where to end up is the wrong question. You must test the chip yourself.
Finally it's not the FSB that will kill your chip it's the voltage. I wouldn't go past 1.37.

Pretty sure the 8400 only does 9.0 multi, which is awesome too. Running my e8500 at 9.5 multi and 464fsb for 4.21Ghz with 1.41v.

Will be working on getting this damn board to run over 500FSB (stuck on DET RAM) and I'll drop the multi, as well as overall overclock and voltage (to prolong the life of this e8500). Wanted to get the ram as close to 1000Mhz and I can do that because the NB is on water, and would love to keep it 1:1.

Where's your NB? Many need a high NB voltage to hit 500FSB.

Have tried the NB at 1.61v, to no avail, hangs on DET RAM every time. I'm running 464 right now no problem, but any time it seems I go much over 480, I run into problems, same with my quad, and I'm running an e8500 now, crazy.

Ooohhhh! I missed that 8GB of RAM That's probably why you can't get to 500. If you want, to see if you can get there with 2 sticks of RAM instead.


Edit: Oops. I think we just hijacked the thread. Sorry.

the hijack is ok..... i ran into a problem i tried to change3 some setting and now for some reason cpuz is only saying I'm getting 2GHz instead of 3 because the multiplier is at 6.

i check the bios and it says its still at 9 but for some reason something isn't right. Now i'm confused.

edit: If i watch CPUZ about every 10-15 secs it will change to a mulitplier of 9 then change right back to 6. what could be causing this....????

Intel speedstep, make sure it is OFF for overclocking! Does that to conserve energy and generate less heat by dropping the voltage/frequency.

i have checked everything i could think of.
