Highest OC's at stock voltage.

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

 
Nicely done.

I had my Phenom II 810 @ 3.315GHz on stock voltage, not much to brag about.
 
Running an amd 965 at 3.8 and nb 2200- wouldn't call it fully stable yet, but it has handled 6-8 hours vid watching and random usage, an hour's everest stress and an hour and a half's Napoleon total war at full settings, I know 3.7 to be stable; things look promising. Just wish it didn't break cool and quiet.

Oh, also note RAM is at 1333, once I get some new stuff that will be upped.

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.
 
My Opty 170 clocked to 2.8GHz on stock voltage, my current CPU only does an extra 500MHz or so before I have to start cranking up the vcore though.

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.

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, :D it would mean tweaking mine to see if I can get 4150.

Watch this space. :D

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. :D
 
That is still an amazing increase...especially as it's the supposed lower-binned E6xxx series as opposed to E8xxx.

It does also really show that high VID doesn't mean bad clocking ;) I would put 1.36-1.38V through that chip and see if you can get it stable at 4.5+GHz..it looks like it may be capable of it.

This is currently what I am trying....will post back after 2 hours or so. The chip is IBT stable at the same FSB but I normally have it at the 9x multi and 1.344V for 4510MHz....so I just dropped the multi to 8.5 and the voltage down to a bit below VID to see what happens :D

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

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.
 
It's generally accepted that anything up to 1.4V and 1.4vtt is save for 24/7 provided temps aren't to insane.
 
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.

Thanks. Why am I making the switch?

Well my original plan was to wait until I could snag up a cheap Q9550 E0 or something and get a nice 4GHz + clock...but prices of 775 quads have been staying the same if not increasing......and by selling my mobo and CPU I will hopefully be able to break even or come very close to it switching to Phenom 2. I can use my current DDR3 as well.

So basically I am upgrading to a quadcore setup for close to free...
 
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. :)

 
Nice job....for stress testing you can go into the 80s and it will be fine. The max temperature rating spec'd by Intel are not the coretemps but tCase which is the sensor on the IHS
