Just got this system built, with a Intel Q9550 2.83 GHz, Asus Rampage Formula 775 socket MB, 4 GB Corsair Dominators CM2X2048-8500C5D DDR2-1066, BFG GTX 285 OCFU video card. W-D Caviar Black WD1001FALS 1TB hard drive, Zalman 9700 cooler, housed in a Cooler Master 690.

High possibility of changing memory to GSkill's DDR-1200 PC2-9600 2048MBX2.

New to overclocking, and would be most appreciative for any help and guidelines and settings to overclock this system. Thanks!!
 
Do you have a C1 (SLAWQ) or E0 (SLB8V) stepping CPU, and what's the VID of your chip (found using Real Temp--> 'Settings' page--> VID)?
 
Wow... nice VID... lowest I have seen! CORRECTION... still low!

I wouldnt bother with 1200Mhz ram unless you are entering an overclocking competition.

Check out the guide in my signature, that should get you started!

Keep the CPU around 72C while stress testing (P95 Small FFT) and have at it!!!

Redduc will probably give you some cookie cutter settings to start with... :)
 
Q9550 Overclocking Help

All I'm wanting to do is to overclock and make it a little faster for online Sim Racing. Just want to bump it up a little to be safe, and not worry about burning up or losing mt CPU or damage to anything else

I went into the Bios and changed a few things to see what the results would be.

AI OverclockTuner-Changed to Manual
CPU Ratio-8.5
FSB Strap to NorthBridge-Auto
FSB Frequency- Changed from 333 to 400
PCIE Frequency-100
DRAM Timing-Set To Manual with settings to 5-5-5-15(Corsairs recommendation)
DRAM Voltage-Set at 2.10 (Corsairs recommendation)

This gave me 400@1066MHz. Speed is now 3.417

I noticed the temps went up a bit when I changed to thes settings.

Any opinion on these settings? Is it safe or feasible to run?
 
You now need to stress test it (like the guide says).

Quick and dirty = Intelburntest
Long = Prime 95 small fft for CPU, Large FFT for system.

You did all this with a Vid setting of 1.1875?:shock:
 
Im going to guess the voltage was on auto as well, which will raise to compensate.
 
It must be. Mine is at 1.275 8.5x390 = 3.315 ghz. I'm running Prime 95 right now and my temps are 52 c on every core. Been running for 2 hours now.
 
Q9550 Overclocking Help

Yes, the voltage was left at auto. Is that okay? Went back and checked the Vid Setting on Real Temp after changing the bios to the above numbers posted earlier in settings and it still reads 1.1875 for the VID.


Kinda confused here on Prime 95. On Prime 95 small fft for CPU, how many #workers do I run for this test, One or all four?
 
Q9550 Overclocking Help

Guys: Thanks for posting and giving me some help and where to get info on overclocking. Read a lot on it and changed some things over the weekend.

So , I'm starting over so let me list what I have and what I did.

CPU- Q9550
MB- Asus Rampage Formula (775 Socket)
RAM- Corsair Dominator 4GB 1066 MHz PC2-8500C5
Video- BFG GeForce GTX 285 OCFU 1024 GDDR3
PSU- Corsair GDX850w
Cooling- Artic Silver 7 for CPU
Zalman 9700 CPU Cooler
Cooler Master 690 with- 1 CM 120MM front intake fan- 69CFM
2 CM 120MM Side Panel fans- 69 CFM
2 CM 120MM Top Panel Exhaust fans 69 CFM
1 ThermalTake 120MM Rear Exhaust Fan and
1 ThermalTake 120MM Bottom Intake Fan both
manually adjusted from 38.6 to 93.7 CFM
1 Evercool 80x80x15 side panel intake fan for
cooling to back of MB.

Changes made in Bios were: Overclock-Set to Manual
CPU- Set to 8.5
FSB Frequency- Set to 400
PCIE Frequency- 100
CPU Spectrum- Disabled
Vanderpool- Disabled
PCI Clock Synchronizatio- Could not Locate,
unless listed as a
different name.
Everything else left at AUTO.

Since last Friday, ran PRIME 95-Small FFT's for 12 Hours- All Passed.
Large FFT's for 12 Hours- All Passed.
Blend for 12 Hours- Passed.

Temps from REALTEMP and CPUID
Temp Readings 4 Cores- 38/36/36/36 Celsius

VID- 1.1875 from Real Temp/CPUID

VCore Reading- 1.192 from CPUID

Clock Core- From CPUID Core Speed-3400.3 MHz
Multiplier- x8.5
Bus Speed- 400.0 FSB
Rated FSB- 1600.0 MHz
Core Voltage- 1.192 V

Memory-DRAM Frequency 533.4 MHz
FSB DRAM 3:4
Settings 5-5-5-15- 52 Clocks 2T (Recommended by Corsair)
2.10 Volts (Recommended By Corsair)

GPU Core Temps- 43 Celsius from CPUID

Now, the only thing I troubled about is not finding the PCI Clock Synchronization to change, unless either it's not listed or is listed under a different name I don't recognize.

The Settings for the CPU Vcore is set at AUTO. Is the core voltage CPUID listed at 1.192v safe to change from auto and post there, and is there anything else I need to look at at possibly change?

I'm trying my best to get this right before Wednesday, thats when our 2010 season of Sim Racing begins starting at Daytona.

Again, my thanks and appreciation for the help an info!
