Where to go from here? Q6600 B3 Overclocking

[Daemas]

Having some trouble getting my Q6600 to overlcock any high than 3.0GHz. Was trying to see if anybody here had any tips.

Q6600 B3 VID 1.3125
GA-EP45T-UD3LR (rev. 1.0) with latest BIOS (F10)
GeIL 4GB (2 x 2GB) DDR3 1333 7-7-7-24@1.5v (currently running at 6-7-7-16@1.5v)
Enermax Galaxy Evo 1250w
Prolimatech Megahalems Rev. B with 2x Yate Loons Mediums in Push/Pull.
Termalright HR-05/IFX + Panaflow 80mm fan

No matter how high I raise the voltage (1.4v - 1.425v) I can't get the chip to prime with any stability. Temps are 26-28idle and 50-55ish under load with prime95. (a little high from where they were when I was dicking around with it last year)

Here are my settings:

Robust Graphics Booster: [Auto] (my board doesn't even have onboard video so wtf)
CPU Clock Ratio [9x]
~~~~~~Clock Chip Control~~~~~~~~~~~~~~~~~~~~
CPU Host Clock Control: [Enabled]
CPU Host Frequency(Mhz): [333]
PCI Express Frequency(Mhz): [100]
C.I.A.2: [Disabled]
~~~~~~Advanced Clock Control~~~~~~~~~~~~~~~~
CPU Clock Drive: [800mV] (default optimized by the board)
PCI Express Clock Drive: [800mV] (default optimized by the board)
CPU Clock Skew: [0ps]
MCH Clock Skew: [0ps]
~~~~~~DRAM Performance Control~~~~~~~~~~~~~~
Performance Enhance: [Standard]
(G)MCH Frequency Latch: [333MHz]
System Memory Multiplier (SPD): [4.00B]
DRAM Timing Selectable (SPD): [Maunual]

CAS latency Time: [6]
tRCD: [7]
tRP: [7]
tRAS: [16]

~~~~~~Voltages~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Load-Line Calibration: [Enabled]
CPU Vcore: [1.37500v]
CPU Termination: [1.200v]
CPU PLL: [1.550v]
CPU Reference: [0.805v]

MCH Core: [1.100v]
MCH Reference: [0.760v]
ICH I/O: [1.550v]
ICH Core: [1.100v]

DRAM Voltage: [1.500v]
DRAM Termination: [0.750v]

C1 states and the EIST whatever power states are currently enabled but even if I disable those features I still can't get anything higher than 3.0GHz. The voltages are currently just at whatever the default should be because I do not have to raise them to obtain 3.0GHz.

Are there any specific voltages I should try bumping other than my Vcore? If so, which ones and how high can I go with them?

I'm just trying to eek out that last bit of power from my Q6600 while I wait for p67 motherboards to get their bugs fixed.

Thanks in advance guys.

I wonder if the RAM is holding you back. Can you lower the "System Memory Multiplier (SPD): 4.00B" to something lower, and then crank up the FSB some more?

doesn't work :/

That's a high VID to start with. 3.0 Ghz may be all you're going to get out of it.

IIRC, the B3 stepping chips were not nearly as good at overclocking as the later G0 stepping chips. You may be out of luck here

3.0 may be all you can get. i had a L2 stepping e2160 that would not do anything over 3.0.

Your voltage is too low to give you any higher speeds.

Up your CPU voltage. And try to keep the ram to 1:1 You should do 3.4Ghz with a little bit added voltage from the 1.31 that your at.

Look at what my voltage is in sigrig !

This may be the case. The CPU could be pushed a bit further but I wouldn't be surprised if a B3 only could get to 3GHz.

Max VID for a Q6600 is 1.5v. Don't expect Tweakboy's OCing results, there's a significant difference between B3 and G0 chips. I used an E6600 B2 and couldn't get past 3.2GHz stable, the only difference was two cores instead of four, the basic principles are the same.

Just a thought...if your RAM's CAS latency is at 6 I wonder if it would be just enough to make it unstable.

You have a G0, he has a B3, his will virtually never overclock anywhere as high as yours.

Your right,, sighs, He should get 3.2 out of it at least, shouldnt he ?

Hey Mark you using Sony fw900 ? Lol I recently retired mine its sitting in the corner of the room taking giantic space....

My B3 hit 3.6Ghz under water at 1.54v. My G0 hit 3.73Ghz at 1.54v as well. My B3 under air cooling reliably hit 3.33Ghz and that was around 1.42v or so. In fact, that machine is still clocked at 3.33 when I decided to give it to my father. Been going strong for... 3 years now? Amazing.

There is no "should." YMMV.

Very amazing. I've seen a few B3 Q6600 that were 3-3.2GHz max, and none higher.

The B3 i've owned could only hit 3.15 @ 1.45v and it was hot. Ran it normally at 3 @ 1.4v. My one had the same VID. Don't think you'll be able to get any more out of it.

G0 Q6600 were much better, had one running for a year at 3.43 ghz at 1.4v

Your B3 was actually ~10 degrees cooler than you thought it was. Intel published the proper TJMAX about 15 months after the Q6600 craze. By that time, the Q6600 was a thing of the past.

The above data will mean that for some users the temperatures currently being reported for their cores are actually quite a fair amount off ; assuming we take Intel’s word for these maximum temperature values. For example, most temperature reporting programs would use 85°C as the Tjunction Max for a B2 E6600. According to Intel, the "official" Tjunction Max for this processor is only 70°C. That means that for a program which does not take into account any slope error, the temperature would be reported 15°C too high.
