help with an e6400 overclocking?

post #1 of 22
Thread Starter 
hey everyone.

pretty much as you can see from my sig rig; i've got an e6400 batch#L633A991 with a dfi lanparty dk p35-t2rs and a zalman 9500
i can go to 3.2 fine with 1.30vcore; 2.1vdimm 1.3 on the nb core.

what i want to do is clock higher than 3.2 so i can fold better. i guess as a last resort is to buy a q6600 but that would be later hopefully in the summer. but for now i've tried running on a 1:1 ratio with an fsb of 450 running on 1.39vcore but unstable because of the cpu. i'm not quite sure what else i can do about it. i've also tried 425fsb with the same 1:1 divider and dropped the vcore to 1.375 but still stable for a while but would give me an error. am i doing something wrong? should i get a new cooler? is it my case air flow? mmm any output would be deeply appreciated.

-thanks

Try a little more voltage then you've tried,maybe1.4v.And run cpuz in windows to see what you are getting under load.

if i run orthos on small ffts and it fails. what could that mean? does that mean that the cpu needs more voltages? or it could just not work that higher? i'd just like to run it higher than 3.2

Usually it's a sign of the CPU failing. You could add more vcore, but I have no idea what your temps are. Do you have a link to the RAM??

You could also try upping your CPU VTT voltage, 1.5 volts max.

Mine is at 1.5, 1.47 at load. Do not go over 1.5 however, it will be very hot, and be very bad for your CPU

Doesen't really matter, run it with small FFT's for now just to get a good idea for temps.

Usually 15 minutes achieves highest temps on CPU. But if it seems like it keeps going up higher as you are reaching the 15 minutes, even ever so slightly, then run it until you feel that it has reached it's highest temp (at least 15 minutes, though. I need the highest absolute temperature). Coretemp is most accurate, but HW Monitor is good for showing highest temps and voltages on all system components. Just double check to be sure you are using the latest versions (in the links) Could you post a screenie with both of these alongside Orthos running?

Also, could you post a web link to your RAM?

Those should help give me an idea where to start with your setup.

oh. i thought i posted it yesterday, i guess not. mmm http://www.newegg.com/Product/Produc...82E16820231065
thats my ram. i'll post back in 15~20 mins with my temps.

this is at 3.2 atm so yeah.

I've been having the same problem. I couldn't go higher than 3.2ghz. I would boot in windows, run orthos for like less than 1 min and computer would shut. Right now I believe the temperature is the problem, so I'm waiting for my WCing system to be finished and then I'll continue to OC. From what I've read, people have gone 3.6 for this e6400.

EDIT: This is my thread when I needed help. Maybe it can give you some advice.

Right now I am running my e6400 at 3.3 with 1.4 on the core. At 1.4v I have ran at 3.5~3.6 rock solid stable but temps get a little to high for me with air cooling.

Oops, just read my post here. Just to clarify, be sure to run HWMonitor the full time that you are running Orthos, to see any peaks in voltages and temps.
