Max Core 2 Duo Overclocks at Default Voltage Info

[The Asgard]

Hi there,
Thought it would be interesting to see how the C2D are performing at default voltage. One of the things that always impressed me about the Opteron 939's was the ability for some batches to perform 3G's at default voltage.

I currently have a 6600 that will do a tad under 3.6G at default voltage which is 1.35 volts.

Would be nice to get some info on what batches are performing the best.

Orthos stable for 1 hour is a good indication of stability and works for me so if you could perform this I would appreciate it.

See my screen shot for required info.

I'll will compile a list depending on the response.

Remember *** Default Volts Only *** Just set Vcore to Auto

Any VCore measurements should be done under load otherwise the power management will reduce it.

I will start the ball rolling

Dude crop your screenshot... it's way too big and even stretches the screen on my 1690*1050 rez. You can cut out almost the entire right side of the pic there.

I'm going to test this today and will add to this post with the results... i'm thinking 3.2-3.3ghz or around there though. Not fantastic.

Done.

Sweet m8. Nothing wrong with 3.2 to 3.3 at default.

 

[w3bbo]

iirc 3.25ghz was my max stable on default. Been a long time since I was at such a low vcore though

 

[trojan698]

E6300, 3Ghz, Stepping to follow once I find the bit of paper

 

[FreeStream]

3.2ish IIRC

3ghz at 1.275V

 

[The Asgard]

If you could please supply

CPU Batch Number
Motherboard
Cooling
Actual VCore in use. Everest is good for this.
Overclock
1 Hour Stability test with Orthos ( if possible )

Appreciated

I have played with over 20 6600 now with my latest being Week 31. So far the best clockers at default are Week 29's.

Is that at default in the bios m8 ? Could you look at it under load ?

Any VCore measurements should be done under load otherwise the power management will reduce it.

E6300 - No batch code?, bought as OEM, B2 stepping
Gigabyte GA-965P DS4
AC Freezer Pro 7
1.297V (BIOS says 1.35V)
2.84GHz
Fully stable running 2 threads F@H 24/7

My machine defaulted to 1.35V but your post above says 1.325 is the stock voltage - are Gigabyte giving them a bit extra juice on purpose?

Try Looking at the Load VCore voltage. It should go up. C2D drop the voltage at Idle

 

[Xez]

Nope mine on idle is 1.3 to 1.32v and load of 1.296v set to default voltage in bios

 

[WJA96]

That is under load. The first thing I do is turn off C1E/EIST/Speedstep and then stick on Folding@Home. None of my machines ever run less than 100% CPU utilization.

 

[The Asgard]

Must be Vdroop then

 

[WJA96]

Or more likely the voltage measuring chip is a piece of junk. Voltages are actually only relevant between measurements on the same machine, surely? I've never seen one of these programs report the same voltage that the BIOS is actually set to. Has anyone?

^^ Correct.

I haven't seen a mobo report the same as others exactly.

1.25V in BIOS = 1.208V under load, 1.212V idle.
1.5675V in BIOS = 1.504 under load, 1.524V idle.

CR.

Orthos stable and running two cores of F@H 24/7 for the last 3 weeks.

don't have all the other bits and bobs off the top of my head, but my 6400 does 3.2ghz on stock volts but i need to slacken mem timings, i've had it in windows at 3.4ghz on stock volts also .

*note as you can see that's on air and on a p5b deluxe!
