Highest OC's at stock voltage.

[TechnoCorruption]

I recently upgraded my case and cooling so have been overclocking my E6500 today. As always the first thing I did was see how far it could get at stock volts. I was pleasantly surprised and it got me curious to see how far other people have got using no more than their stock VID. (Must be 2hours+ stable)

Stock - 266x11=2926
OC - 370x11=4070
Increase - 1144MHz

Here's a link to mine, although Ocuk did all the work, I just raised the fsb

Very nice, a 1215MHz increase is awesome for stock volts.

I have my E5200 running at 3.72GHz (from 2.50GHz) on stock voltage, using a Zalman CNPS9700 cooler. Ran fine in Prime95 for 12hours when tested in a year ago.

An increase of 1220MHz is real impressive for stock voltage.

The Pentium DC's seem to be awesome clockers for the money.

Although it makes me want to see if I can beat your 1220MHz, it would mean tweaking mine to see if I can get 4150.

Watch this space.

damn I've had a bunch of e8500s that have done 4.1-4.2GHz on less than their stock VID but have no proof

I will only have my E8400 for another day or so...maybe I'll see what it can do on stock VID>

Go for it dude, I am currently priming away at 4180 to see if I can get better than the 1220 increase a few posts above.

Best of luck mate, (Although not too much as if we both pass you will have surpassed me by 5MHz)

Do these new revisions of the wolfdale core still suffer the degradation issues of the earlier ones?

I would be safe to go to 1.35? I still have a bit of headroom left on my cooler.

Is vtt the same as FSB Termination voltage?

If so I am currently at 1.3v.

After I have found my max on stock volts I may be tempted to see how far into the 4GHz range I can get.


Edit: I am going to have to bow out, I just had an error after an hour and a half. That was using 380x11=4180. I knew it would not do 4230 as I tried that yesterday so I think 4.1 is around my max.

Giving it 1.34v now and trying for some 400x11=4400. That would be a nice overclock to run with speedstep on a daily basis. My ram is DDR2-800 so upping the fsb past 400 will be overclocking that too.

Yep, same thing.

Thanks mate.

1233MHz OC with less than stock voltage. I'm going to miss Intel

That is an amazing clock mate, how come you are making the switch?

Fair play, a free upgrade can only be a good thing.

I tried upping the voltages a bit to see how far I could get on this AC Freezer7.

My rig was getting a little toasty (70c) at 4.4GHz with 1.36v so I have dropped back to 4.23GHz at 1.32v.

It just passed 8hrs of prime without going over 64c so come the summer I can up the fans a bit and still have a few degrees of headroom.

Well impressed with it seeing as it only cost me £50.
