Q6600 OCUK Latest Batch Codes and Performance

[SimonMaltby]

Got my Q6600 G0 today and here are the codes

SLACR
L725B020
Pack Date 16th August 2007 (wow)

So far i'm sat at 4.02Ghz in XP
Temps very nice at 45c Idle - For once all the temps agree
Asus ProbeII and Core temp both show the same.

The chip puts more pressure on the mobo which is where i'm not sure about stability. Can do superPi no probs at 4Ghz, working on Prime.

Just going to let it bed in for an hour or two then see how stable she is.

will do, but trying to lean quad first... its quite different

Screen shots and volts please

Screen shot will have to wait a bit as my OS corrupted as i pushed the NB and FSB voltages about

Vcore is 1.56v

I should stress that this 4ghz is not stable yet. Heat seems to be the issue, but not the chip heat, heat on the motherboard at this FSB. I like to run nice and silent, but the only way i can stay stable is with fans on about 75%

Just to explain my dilema.

Q6600 G0 or E6850 G0 - which to keep?
The E6850 benches at 4.2Ghz and is stable for Prime at 4.05
So far the Q6600 looks like it may bench at 4Ghz but be Prime stable closer to 3.8Ghz due to the mobo getting too hot.

This is turning into a real dilema... will Quad be the one to have as new games come out????? HELP

Anyway, just re-installing the OS and will try again.

I tried the Bioshock Demo as one of the indicators when trying to decide between the e6850 and the Q6600

Although i did not take any bechmarks, i found the Q6600 at 3.8Ghz noticably smoother that the e6850 at 4.05Ghz Thats why i decided to keep the Q6600 in the end

 

[SimonMaltby]

Now i have settled on the Q6600 here are my current results.
This is based on fairly basic water cooling as per my sig..

Best Overclock 4140 Mhz (SuperPi 1M and CPUz validated)
Best Useable Overclock 4050 Mhz (SuperPi 32M - 3DMark 2006 - Game Play)
Best Prime Stable 3804

Hi Simon

What voltage are you putting through yours and what is the motherboard? Any vdroop issues?

The one I am testing seems to be getting better with time, now at 3860Mhz stable on air, gonna shoot for 3900MHz and then see if I can maybe get some benches out of it at 4000MHz too which will be an achievement on air.

Its not easy to get stability... vcore is only one of the challenges.
I'm using the Blitz Formula and have had to work hard at the PLL voltage and FSB Termination voltage - these are both set quite high but dont seem to cause excessive heat anywhere.

I have set FSB termination to 1.70. PLL to 1.71 for stability
The NB did not seem to need more than 1.55
Vcore...
For 3.8 Stable i'm at 1.55 in the bios - the monitor reads 1.54 Tru and it droops to 1.52 under load.
4.05 needed 1.6v 1.58 True
4.14 needed 1.625 bios - 1.6 True

Temps are fine for me...
at 4.05 - idle core about 38c NB at 47c - load jumps to 65 - 76c when trying to prime... I have managed 15 minutes of Prime at 4.05 but then it falls over, clearly heat is building up somewhere.

Gibbo... when you say stable please can you define...
I find that 100% stable is that you can Prime on All 4 cores at once (i.e. 100% CPU load) for at least 30 minutes.
Real life stable means i can game and do any real world tasks without it falling over. I am real life stable at 4.05

Also running Vista requires much greater stability than XP. I find you have to be able to run at least 32M Super Pi or preferably Prime in XP for Vista to be stable even on boot.

Hi there,
which cpu are you guys ordering the standard power one ? or the
Intel Core 2 Quad Pro Q6600 "Energy Efficient 95W Edition" version? there on special this week will order one not sure which one.

The 95W Low power one is the one to get as it is more overclockable.

You - you - you beat me

Mine at 4050 = 16017 u got over 100 more

That's as far as I've got for now. Ignore the temps, Speedtemp is off the mark, but I wish my first die was as good as the second .

Jokester

My dies are much the same as yours, but interestingly i find that when prime falls over (the rare time the PC does not just re boot) that its the 3rd core that fails - decpite, like yours it beeing at a lower temp.
