[Example O.C. System] Q6600 3601MHz

My setup is:
1. Intel Quad 6600 Stock 2.4 GHz from Newegg.com
2. P5N72-T Deluxe Open-Box Mobo from Newegg.com
3. GSkill 40$ ram, 4GB pc6400, 800MHz
4. Sapphire Radeon 4870 512MB 256-bit pcie video card
5. Antec Neo Power 550Watt Modular PSU
6. Koolance Exos2 System, 3 Blocks (CPU, Nbridge, Sbridge)

I have this system overclocked. The voltage settings are pretty high though. The only reason I have them this high is because of stability. I can run through 3d mark's default benchmark with no problems at all, 100 times, over and over. I can run prime 95 successfully for 16 hours straight, but, for some reason I am crashing after many hours.

I do not know why, and, I am looking for help. I wonder, maybe I have pushed the motherboard (1600 MHz FSB O.C.) and processor (400MHz FSB) to its limits. Maybe I went way too high on the voltage?

Voltage Settings:
1. VCore - 1.65, in CPUZ it appears as 1.536
2. PLL - 1.70
3. VTT - 1.48
4. NB - 1.70
5. SB - 1.50
6. 1.2V - 1.46

With the liquid cooling, it is running at about 50degrees Celsius at full load, under prime 95. I do not have a water block on the chip on the mother board marked "BUS". I have a solid heat sink on in. I can not (short of drilling holes) find a way to install a block on this. I am sure someone makes a block somewhere, for this whole motherboard, volt regs and all.

If someone has a similar setup and can share some insight I would greatly appreciate it.

In addition, I have the 4870 maxed out in CCC. Is there another utility I can use to push it up to say, 900MHz? Core clock?

Thank you in advance for any help.

Replace CCC with ATI Tray Tools.

Wow thats a lot of voltage for 3.6 Ghz, I ran mine beleive it or not around 1.43 V... altough I must say that with these voltages thats great cooling performance... But then I have an Asus Rampage and b0 stepping cpu, yours might differ. I dont know if you tested but If I were you I would try to pull down the volts gently down.
 
Yes, indeed. That is a lot of voltage.

I reached 3.6 GHz. with my G0 Q6600 on air with a TRUE in an Antec 900 case.Vcore was 1.45 volts, drooping to 1.42 volts. Core temps hit 61 C. - 65 C. after 24 hours of Prime95.

Well I guess I have a golden chip from intel 3.6 Ghz stable many hours at 1,36 Volts, it rans problem free however NB and SB voltages go crazy after several hours of prime95 in asus probe application, but i guess it is a sensor failure because PC keeps running with no problem, it shows values like 4 volts for a second or two then drops down to normal levels.

Hi i am running a Q6600 cpu stable at 3.6 GHz,on a asua p5q motherboard with 2GB of ram,

Case --- Thermaltake Armor LCS VE2000BWS
PSU------Jeantech Storm 700w sli/cross-fire
Nvidia Geforce 9400 GT
Corsair XMS2 Dominator PC2-8600

here is a list of the setting i am using


Ai Overclock Tuner [manuall]
CPU Ratio Setting [09.0]
FSB Frequency [400]
PCIE Frequency [101]
FSB strap to north bridge [333] this is easiest to maintain stabiliy but can be left auto (if left at auto the DRAM Frequency would be 1066)

DRAM Frequency [961]
DRAM Timing Control [AUTO]

DRAM Static Read Control [AUTO]
DRAM Read Training [AUTO]
Mem. OC Charger [AUTO]
Ai Clock Twister [LIGHT]
Ai Transaction Booster [MANUALL}
Common Performance Level [11]

ALL PULL-IN SET TO AUTO

CPU Voltage [AUTO]
CPU GLT Reference [AUTO]
CPU PLL Voltage [1.54] Do NOT leave auto as that massively overvolts
FSB Termination Voltage [1.24] Do NOT leave auto as that massively overvolts
NB Voltage [1.26]
SB Voltage [1.10]
PCIE SATA Voltage [1.50]

Load Line Calibration [Enabled]
CPU Spread Spectrum [Disabled]
PCIE Spread Spectrum [Disabled]
CPU Clock Skew [AUTO]
NB Clock Skew [AUTO]
CPU Margin Enhancement [Performance Mode]


tested with OCCT and stable
