New to Overclocking : E6750

post #1 of 6
Thread Starter 
Hi everyone.. this is my first post, but I have been checking these boards more often as I am interested in getting the most out of my processor.

I have an e6750, running at 2.66ghz right now.

My PC specs are :

C2D e6750 2.66ghz - Thermaltake Blue Orb2 heatsink
eVGA 680i LT mobo
2x XFX 8800gt alphadog edition 670mhz
4gigs OCZ REAPER HTC @ 800mhz
Corsair 620w modular psu
Vista x64 home premium

I have read that some people have been able to achieve 3.2ghz without having to tweak the voltages.. Altering the voltages is something I'm new to, but I'm not opposed to trying it.

Just looking for some opinions of the best way to OC as a first timer. Any ideas would be appreciated!!!

Thanks for your time!

You should really read the FAQ's on how to overclock that would solve your problem.

But i'll give you the gist of it.

Simply load into the bios and increase your FSB by 10.

Save settings and load into your operating system.

Run a stress test like prime95 for 8 hrs. If the computer is still working then you are good. If it reset itself then you have gone too far and undo your changes.

Keep increasing your FSB by 10 until you reach your goal. Also remember to monitor your temperatures so that you are not running to hot.

At first you can probably increase your FSB by 100 because it should definately increase that much but its up to you.

yes incriments of 10, and it should go up at least 100, but in incriments of 10, not all at once. download a program called OCCT it will cut your testing time down to 2 hours instead of 12 (i only would do 6-8) but the more the better... but do a search here and on google for "overclocking 680i" and see what comes up, there is probably a useful guide around here or maybe forums.nvidia.

Im sure there are some other useful steps in bio you need to adjust.
eist - disable
cia2 - dis
speedstep - dis
fanspeed - you want your cpu fan at 100%

but again do some research on your motherboard and bios settings, Im sure you can get to 3.4 or 3.6 with that setup, granted you increase voltages and your cpu fan holds up.

Thanks for the input guys.

I found this http://pc.ign.com/articles/747/747606p1.html while searching for overclocking with the mobo I have.. Anyone have anything good/bad to say about the IGN oc guide?

the only thing I would suggest any diff would be the voltage part..
Im not well versed on the 6750, but 1.45 right off the ge go is a tad extreme for a cpu volt.

Id say see what the voltage on auto is, then increase it a tad. say if auto is 1.325, set it to 1.35 and see how far it goes on that setting.

Once you find it becomming unstable, bump it up a notch, say 1.375 and so on til you find max stable clock, with reasonable temps...

search this site for "e6750 max temp" and "e6750 max voltage" Id suggest staying 5 below each,

if max temp is 75, stay at 70 or lower. if max volt is 1.55 stay at 1.50 or lower... but thats just an analogy, and my opinion...

Why don't you use the guides stickied here? Also, go to the user CP and put your system specs in.

If I were you, I would kick that FSB up to 400 right off the bat. That will only take you to 3.2GHz, which you can probably do without a vCore increase. Once stable at 3.2, then move up by 10 at a time until you are happy.
