[CikaNovo]

I found a sweet spot for mine.3.2 GHz with only 1.246 volts Primestable.

Hi,
I have a SLACR on order. I should receive it on Wednesday.
I have an overclocking question that I would greatly appreciate if someone could answer.
If both CPU speeds are the same:
Would it be better to have a greater FSB and a lower Memory speed? Or, a lower FSB and a greater memory speed?
Lets say 1:1 Vs. 5:4

Lots of different opinions on that one re timings, extra bandwidth etc. Have a read of this article http://www.thetechrepository.com/showthread.php?t=195 - very informative and educational - posted by freecableguy who knows what he is talking about. After you have absorbed the detail download the referenced overclocking guide speadsheet and insert your data to find out what will work best for you.

Many of you have very impressive overclocks but your power bill will be even more impressive when you run at 4Ghz with 1.5v+

No sh*t dude. What happens when you run 1.6Vcore and turn on prime95?
My poor P5B and PSU 4 pin connector is fried

Had to fix it up.


P.S. Yes I know the red wire is for 5 volts, but I used the fried 4 pin connector 2x 12v and 2x ground.

How do you know if the chip you're buying is G0 or not?

[Darkatom]

Look for "SLACR" at the end of the product code for a G0.

Where do you see the "product code"?

You don't really find out that you have one until you get it. Unfortunately.

Buy from like here:

Guaranteed G0, cheaper.

Thanks sesdave, I will read that now.

So whatswhy my p35-dq6 has 2*12V connections
Thank God i connected both then i tried 1,65V on my QX6700

Hey ya'll
Currently sitting at 3800Ghz, q6600 g0, 8x475, 1.5v BIOS, 1.48v Speedfan with the gear in Sig, all is well working in "everyday computer workflow" aka no crashed on ANYTHING, but.......

When running 2 instances of Orthos, small FFT's, with the Processor Affinity's set to CPU0/1 for one instance and CPU2/3 for the other, the CPU0/1 instance fails after only 10 seconds at this voltage....the other one just runs and runs (aka about an hour before I stop it)

Is this indicative of not enough vCore? I will check the q6600 OC Database Thread to see what I can generally expect to have to set it to. But would you guys have any general advice?

Please don't waste my and your time posting "up the voltage and find out for yourself jerk"

Your multimedia crunching poster,

What is you CPU temps?

[jeeka]

Temps are outstanding for AIR and this time of year:

At this OC,
Idle:
Core #0 = 39C
Core #1 = 37C
Core #2 = 32C
Core #3 = 35C

Orthos (load):
Core #0 = 62C
Core #1 = 62C
Core #2 = 55C
Core #3 = 55C

I am aware of the disparity between core temperatures, and mine are slightly out of the norm of what everyone else is measuring. I can chalk it up to:
1) That's the way it is, deal with it!
or
2) I had a slightly slanted (not concave or convex) Thermalright 120 Ultra Extreme that might be putting unequal pressure on the chip when screwing in the mounting screws with equal pressure. I attempted to fix it by lapping down the "top of the hill" side of the slant as much as possible and doing the "Washer between the mounting bracket and HS base trick" that you guys hooked me up with. That actually dropped temps about 3C.

That is good, since the Thermal Spec is 71c. You have some room there.
In addition, you have that temp with the high Vcore.

Have you attempted or considered a stress test like, Orthos and 3Dmark06 at the same time. It would be good if you can complete 3Dmark06 under that configuration.

[timber715]

i dont really think he still has headroom in regards to his temps, as this are only 10 seconds in to orthos... within 10 minutes his temps should be way clear of 71C. i say try to settle for a lower oc that you can be stable in... goodluck

ahh no, within 10 mins his temperature will not jump that much. so he is safe and have a little headroom.

[reflux]

Mine always jump by about 8-10 degrees around the seven minute mark. Got my new G0 yesterday and it's @ 3.6ghz, 1.5vCore, ~70c load under a Tuniq Tower. Pretty chuffed with it

[Alucard-]

I just got my q6600 was suppose to be a b3 but, I got a free upgrade to a g0. I would have gotten a better motherboard if I knew, I just picked up a dfi 965s dark used cause it was dirt cheap. Pack Date 08/22/07 I hope I get lucky with board and cpu getting along with 4 1gb sticks.

It should throttle down past the spec temp. Without being stable, you can't call it a successful OC.
A good OC should loop 3DMARK06 and orthos. That CPU test #1 is a make or breaker.

I have one on order and should have it tomorrow. I set up a new install of XP to go through the BSD

What is wrong with DFI boards? I think they have a good reputation. I hope you have an OS that can read the 4 GBs

Might be because your standoff wasn't even lined up with the hole, see your own pic.. short/POP!

Someone needs to re-size that pic

Good idea....Should I try 2 instances of Orthos AND the 3D Mark 06 run? or 1 Orthos + 3D Mark 06?

Also, should I assign affinities to each program or just bombard the chip and let it sort it all out?

I am testing now, It looks like I will end up with 3.27Ghz, (9x 364) 1456 FSB
I have been looping 3DMARK06 and Prime95 ver. 25.4 (because it is a 4 core test out of the box). I had many BSD's today. So, I think it is a good test.

The max I can go is 9x 366. So I pulled it back a little. I am running 1.3 volts under-load and 1.33v at idle. MAX temp was under extreme load is 68.c, but mostly under hi load around 64c. Idle, in the mid 40c. New heat sink compound today, so maybe that may get a little lower in time.

With 9x 366 I looped the 2 programs for about 3 hours with no errors today.
I just came back home happy to see all was good. Going to run some benchmarks, boot into Vista and run Prime for the night.

On my every day use, I use Power management settings that drop me to a 6x multiplier at idle. Vista performance setting, Speed Step and C1 (EST?) enabled, Power Fan options turned of for max 24/7 air flow.
