No bug, he just disabled 2 cores so he could clock it higher. CPU-Z reads all for cores fine.

Here's my L726A Q6600 G0 with all 4 cores active at 4Ghz

nope, i don't disable anything to clock higher, my mobo dfi infinity p965-s dont have any option to disable the core. i don't know why those 2 cores has been disabled

i thinks it's a bug.

i'm using dfi infinity p965-s

you might need to update your bios to get cpuz to recognize those two other cores.

i'm already using latest beta bios 07-25-07
i don't know why did it happen

i want to revert back to 4-24 bios & see if i can do higher clock

tnx

How can you disable a core anyway? in BIOS or you have to get some kind of software?

read my earlier post
i dont disable anything & i think it's a bug

i also have Q6600 G0 and DFI infniy 965 and cpu-z 1.41 read all 4 cores :

i'm already using latest beta bios 07-25-07

the latest oficial bios its not 7-25-07 , its the one i have 2007-07-03 >> http://us.dfi.com.tw/Support/Downloa...FLAG=A&SITE=US






BTW: OCCT STable @ 3200mhz@1.28v

Well then run 3D mark 06s CPU test and tell me what your score is. It will tell you if all 4 cores are working or not

[Praz]

It's been my experience that when the 965-S is close to total failure with a quadcore as for as stability is concerned the board only uses two cores. Push it just a touch further and it will drop to one core. So yeah it's kinda a bug but you can be pretty sure if all four cores were enabled the board wouldn't be booting.

on the Asus P5B Dlx board there was/is an option in the bios to take a dual core down to just one core.

[crossg]

RLM. Impressive result you got there. So I had to give the beta drivers a go as well. Core temp log shows highest temp was 67 deg under the 3DMark06 Cpu tests. These are great chips and although not stable by any means it sure is fun to rip off a few benches at these speeds on air. Ya still kicked my A$$ by 101 points.

Q6600 G0 L726A850.
1.6125 Vcore (Set in Bios).
448 FSB = 4032 Mhz.
Stock XFX 8800GTX.
OC'd with nTune.
GPU Clock @ 635 Mhz.
GPU Mem @ 1080 x 2 = 2160 Mhz.

The DFI P35 has the option to disable two cores of a quad. The 965-S doesn't have the option. Can only do it if pushed to the edge of being bootable.

[DJSUB]

my OC @ 3.6ghz on DFI Infinity P965s detected all 4 cores perfectly. only the suicide shot 4ghz has that problem
i cant run 3dmark on that clockspeed because my temps are scary

[ZigaWatt]

Nice one, how much vCore?

1.72500v

[mach82]

DJSUB - and moreover your PCI-E link width is just x1, so your results would be extremely low

yes i put my vc on 1x pci-e co'z i dont play games

What videocard are you using?

Exactly. You have demonstrated what I'm trying to say. The cores are detected properly up to the point of almost complete instability. Which isn't an issue with your post as you stated all along that it was a suicide shot. Others may not be so forthcoming when posting screenshots of extreme clocks with this board. I'm not sure if the disabling of the cores is a BIOS or PWM issue.

I'm only using ichill 8500GT XStriker DDR3

Hi,

Q6600 L728A VID=1,2625v

493 max FSB



8M @ 4050 mhz ( crappy ram, just for 4000+ screen)



3300 @ vstock (1,27v real on dmm with IP35 pro)



3300 @ 1,26v with P5K deluxe



3800 @ 1,49v with P5K deluxe

[ChaosMinionX]

Why lock it to 1x?

Also your RAM is cranked way out haha. And I definitely would say that 3.6ghz is not stable by any means, esp with that ram at 1200mhz

[nealh]

it is hard to tell but do the G0 stepping generally hit 3600 at low vcore? or is it very hit or miss

[zoob]

Seems like every single one that njkid32 gets does 400x9 @ 1.408 V (CPU-Z) :P

[ChaosMinionX]

Mine does 450x8 at ~1,45v in bios. 500x7 at 1.5v and 400x9 only takes 1.4375v

I would assume the amount of voltage needed to run a clock from what I have seen has to do with the FSB speed as well. Because they are all 3.5-3.6ghz clocks. Just takes a variety of voltages, generally with my G0 what it boots at for bios voltage up to 3.8ghz takes about .25-.5 more voltage for stable.

If X38 doesnt turn out to be a quadmontser, then I will most likely upgrade from deluxe to premium and see how well it does then.

Hey Neal hows it going. Yes for me it's very hard to tell because of the different mobo's and settings used. I bought my first G0 (L723A891) with a Core Temp vid of 1.3000v and it took 1.6000 vcore to get it stable @3.6 Ghz. Exchanged that chip in short order and picked up a L726A850 with a Core Temp VID of 1.2650 and it's stable @ 3.6 Ghz with Bios set to 1.4150 (bios) and 1.3840 under prime large FFT load. Up vcore one notch for small FFT, 1.4250 (bios). 1.4080 (load). Voltage damper enabled. With the good chips this seems about average. There seems to be more good chips than not so good atm. One thing that is becoming apparent to me is the higher the Core Temp VID the more trouble people have getting them stable at higher clocks. The best chips I have seen is with a VID between 1.2500 and 1.2875 but that's not written in stone either. This thread should give you an idea of how much it varies.
