Do people get 3GHz from their E6600s?

Gman · 22 Mar 2007 at 13:36

good point, think only one core was being stressed fully then the other to about 40%

O/C n00b question...do ya need to increase the voltage for the cpu ureself as ya o/c it, or does it do it automatically itself?

ty

btw, im planning on getting an E6600 with a DS4 so, keeping my eye on this thread for tips

No you have to manually up the vcore your self. Start out on stock vcore, up the fsb and test it using superpi, orthos/OCCT. When it starts failing those then up the vcore one notch, test again, up the fsb. Keep going but don't go above 1.45 volts.

I normally run my E6600 at 3.6ghz with 1.4v.
But I tried last night and it runs 3.0Ghz at 1.24v on my P5B-DLX....Orthos stable! Runs nice and cool......I also have the C1E running, so it drops to 6x multiplier for 2.0Ghz when not busy, for even cooler running.

My L29B E6600 can do 3.25ghz on 1.225v and have currently been working on getting 3.5/3.6 stable. It seems to need about 1.4v which is about average from what i have read. Not all chips from the same batch will overclock as well, it has been known for some e6600 to not even hit 3ghz as was the case here . Earlier steppings seem to do well though. Any of those chips should be able to hit 3ghz, you just need to decide if the extra cache is worth the extra cash

That seems quite impressive to me considering the voltage on the two CD2 processors I have owned state 1.35v as stock. I have run them both overclocked quite a bit at 1.325v and thought that was fairly good but you two appear to be running decent overclocks while 'undervolting' thje cpu by quite some margin!

I would appreciate it if you can get some kinda screenshot to back this up as Im a sceptic!

Old screeny at 3.2ghz, v droop takes it below 1,2v and was done in february in the morning

currently running as sig.

If you say so, but i think most people would've gotten what i said.

No, it was pretty ambiguous.

Heres a quick run of orthos as sig, now back to the gaming

Cheers JeffyB, thanks for making the effort to share your findings with us. I still wanna see a complete round [1/1] before I'm convinced lol

JeffyB · 22 Mar 2007 at 20:07

I'll let it run tonight

Bito · 22 Mar 2007 at 22:22

Mines running overnight too

Noxis · 22 Mar 2007 at 22:26

Mines running as sig

However wasnt there a thread the other day of someone saying the latest batch he couldnt even get passed 2.8ghz?

JeffyB · 22 Mar 2007 at 22:46

There was indeed, can be found here posted a few replies earlier

As requested 12 hour run as sig. can see the v droop on the p5w

Idle

JeffyB do you have the vcore manually set that low in the bios? Reason I ask is that cpu-z has a bug which will show lower vcores than actual. With mine, once I went over 1.475 in the bios, CPU-Z started reporting my vcore as about 1.2. I have seen others reporting the same thing. The voltage is still at what I set it, but the bug in CPU-Z is just mis-reporting it.

If that is the true value (3.4ghz at 1.24v), then you have one hell of a good clocker :eek:

As above really. Trying to decide between 6300 or 6400 and 6600 cause of the extra cache - if I'm pretty much guaranteed to get the 6300 to 3GHz with a good mainboard, what's the equivalent "expected overclock" for a 6600?

I bought into Core2Duo very early.
My DS4 motherboard was Revision 1 with BIOS version F1 to give you an idea.
I also paid a slight premium for my E6600.
From day one I've been running it at 3Ghz without any voltage increases etc.
I could probably take it higher, however there are just two reasons why I'm sticking to 3Ghz.

1. I wanted to overclock my CPU so that it was the same speed as a stock Core2Duo running faster and costing over twice as much - made me feel good about my purchase.
2. 3Ghz gives a nice little boost and means my machine remains 100% stable.
Try and get a little more, back-off, add a bit more - I could spend weeks.
Instead I get a 25% boost for nothing and still have a 100% reliable machine.

Its set to 1.25v manually

Nice work, for future reference one round [1/1] shows up in the area circled

still you get 98%, 1% dropped for not waiting until [1/1] and another 1% dropped for making your screenshots wider than 750 pixels!

Looks like a great chip u have there!

Thanks, been really pleased with this chip clocks really well to about 3.45ghz then the volts needed to stay stable start to jump. The gains dont seem worth the voltages.

Also how long does a round take roughly using the gromacs core?
