E6700 Sucessfull OC at 300 MHz. - Page 2

post #11 of 22
Thread Starter 
Yes my system is on air, I just got a Artic Cooling Freezer 7 Pro ( Fan Cooler ) and it is keeping my system at 41'C ( Idle) with an OC of 300 MHz. from 266MHz.

Are you suggesting that I lower my multiplyer?

Nope not suggesting that at all...

Your multi is perfect. What I am warning against is your temps at an FSB of 350 and I was also letting you know that you will probably max out at that OC due to temps. The chip can go farther but your temps will hold you back.

Last: The link demonstrates a problem that most of us with these boards are running into and it provides a range of FSB's to avoid for stability reasons.

Personally I try to avoid ram multipliers when possible because RAM seems to run better when its 1:1 which at 350 would be 700mhz... The good news is that because its less than the rated freq you should be able to set some aggresive timings.

So what should the timings be set at with what you have mentioned above?

I appreciate the quick respones as well, this is all very new to me!

Here is what I would try first...set your ram to default.
OC as high as you can go with your FSB and vcore while keeping a close eye on your temps. Once you hit your safe ceiling on your CPU clock then try and match the DDR2 to the FSB. So if your FSB is 350 and your DDR2 is set at 700 then you are running 1:1 with your cpu. Then work on lowering (tightening) your mem timmings. I dont have your ram but start at the stock and lower one timing at a time.

Example: If your ram has default timings of 4/4/4/15 try lowering the 15 down to say 13 and then run some stability tests in windows. If your stable go back to your bios and try setting your first timing to 3 and repeat stability tests. This is a long and tedious process and your not going to find your perfect timings all at once. Last once you think you are at your best timings try to run memtest from dos and see if it passes muster if it doesnt then loosen your timings some.

Also: Your Northbridge voltage can be bumped up a bit to help in this arena so you might want to experiment there to.

As a final note: drop that number 23 down gradually too but do that as a final experiment.

Good luck.

sorry I dont have time to edit this for grammar I am at work and need to run...

Sdumper,

The only stable OC that I am able to achieve is the 300, 900.

When I try anything else, I get the BAD blue screen, and am not able to re-boot without powering down and re-starting.

So I think I am going to stay at the 300, 900.

Thanks for the help guys!

Look at the start of this thread while i was still on stock air...i have a table somewhere showing FSB/Vcore and the results...

Everyone's results are different

People are amazed that I can push 1.9GHz from my 1.6GHz Willamette core.. especially with a motherboard brand that nobody ever heard of.

Anyway, good look with the E6700, hope you can get some more out of that beast

Normally I would agree but not in this case. That chip can do 3.3 in its sleep and 3.5 with a little vCore, vDimm and vMCH. These chips were meant to run fast its like using a racing horse for children rides.

Still its your investment Hogan and I respect your decision.

Best of luck.

As it turns out, I was sucessfull at OC ing to 330/660, but the temps bothered me.
It was at 45c idle and around 55c under load, too hot as far as I'm concerned.
I have reverted back to 300 FSB/ DDR2 900 settings, they are stable settings and I like where the temps are at.

Well, to be fair, I did not tell you to set your FSB to 400, although I can see how you might have mis-understood me. Sorry if I wasn't clear. I suggested you set your RAM to 800 and slowly raise your FSB.

I am of the school of thought that slow and steady wins the race. Boosting your FSB in leaps of 20+ at a time may yeild quick results, but I believe it can limit your max overclock.

I believe in raising your FSB by 5mhz at a time and testing, then 5mhz again, and testing.....this is less of a shock on the CPU and can ease it to a higher setting. I also don't mess with timings until I have reached a desired FSB.....once there, I can then see how low my timings can go......doing both timings and FSB at the same time is like fighting a war on two fronts......and if you study history, you can see how that is a bad thing.....

Using this method, I have a 1Ghz OC on my Presler with the stock voltage. I may be able to go even over that, I haven't tried yet......

Sure, it takes time, but things acheived quickly are not always better.
