I just got a new MoBo with the intention of overclocking it. I'm having trouble with some of the options so I was hoping someone could help me out.

MoBo - ASAS P5QPL-VM EPU
CPU - Core 2 Duo Quad 2.4Ghz Q6600 SLACR
4GB DDR2
Air cooled (really well)
Goal - OC to 3.2Ghz or higher

This box will do nothing but render video

Available Options Available Values
CPU Frequency (200 - 800)
FSB (1333, 1066, 800)
PCI Express Frequency (Auto, 90 - 150)
DRAM Frequency (Auto, 667Mhz, 800Mhz, 1067Mhz)
Memory Voltage (Auto, 1.50000V - 2.44500V) 0.01500 increment
NB Voltage (Auto, 1.25v, 1.175V, 1.225V, 1.275V)
SB 1.5V Voltage (1.5V, 1.6V)
CPU VTT (1.2V, 1.3V)
CPU Over Voltage (Auto, +50mv, +100mv, +150mv)
Auto PSI (Enabled, Disabled)
Ratio CMOS Setting (Auto, typed value)
C1E Support (Enabled, Disabled)
Max CPUID Value Limit (Enabled, Disabled)
Intel Virtualization Tech (Enabled, Disabled)
CPU TM Function (Enabled, Disabled)
Execute-Disable Bit Capacity (Enabled, Disabled)
Intel Speedstep Tech (Enabled, Disabled)

NORTH BRIDGE
Memory Remap Feature (Enabled, Disabled)
DRAM Timing by SPD (Enabled, Disabled)
(some graphics stuff)
DVMT Memory (128MB, 256MB, Maximum DVMT)

I suggest we start by setting up BIOS for stable operation @ stock speed. Once we get your system stable @ stock speed and manual BIOS settings, we can get to the targeted 3.2 GHz and make sure it is still stable.

Let's start by pointing you to the software you will use for stability testing:

1. Memtest --> You need to burn a bootable CD. This one is used to find memory errors.
2. Prime95 --> This one is used to stress test your system.
3. OCCT --> This is another software used to stress test your system
4. CPU-Z --> This software will give us information about your system. You have an old version.
5. HWMonitor --> This is a hardware monitoring software.

Once you have the software, please do the following:

1. Set your BIOS in AUTO @ Stock speed (post pictures)
2. Take & post screenshots or report files of CPU-Z and HWMonitor @ idle (just running windows)
3. Take & post screenshots or report files of CPU-Z and HWMonitor @ load (running Prime95 torture test)

Once you provide this info, I will help you stress test & find your configuration for 3.0 GHz stable operation

welcome to OCN! You should go to user cp> add system and fill out your system specs. it will help us help you. ;-)

your best bet is to search for one of the wonderful guides that are on this site for your processor. there is a search box at the top of the page. read lots then try your hand at OCing then if you have specific questions make a thread asking. :-)

good luck

Everything is [AUTO] right now in my BIOS. I have been running video rendering for a week straight 24 hours a day with no issues so I'm going to say it's stable.

I would love to OC this to 3.2Ghz. I've got the Q6600 SCALR G0 which I've read is really good at overclocking.

I appreciate you helping. Thanks much.

PS: I filled out my pc info on OCN. The one I'm trying to OC is my Video Converter PC. The other quad is OCd to 3.0Ghz already.

I am curious about your cpu fan speed.

It seems to be running at fixed speed..
Is it connected to the motherboard's PWM controller?
Or maybe it is a fixed speed model?
Which Thermaltake cooler is it?

Yes, it's plugged into the motherboard. I threw the box for the fan away so I'm not sure which one it is, but it's pretty massive...

mcastaneda68

Ok, first thing is then to setup your rig at stock speed but with manual settings.
The settings I am suggesting here are based on the manual I downloaded from Asus site. If what you have is different, please post pictures of all your available BIOS options, so I can suggest each setting.

So, this is what I suggest you setup for test 1:

- FSB: 266
- CPU Speed 2.4 GHz
- PCI Express speed: 100
- DRAM Frequency: 800
- Memory Voltage: 1.80 V
- NB Voltage: 1.125 V
- SB Voltage: Auto
- CPU Vtt: 1.20 V
- CPU Overvoltage: AUTO
- AUTO PSI: AUTO

Leave the rest in auto and do the following:

- Post Cpu-z & HWMonitor screenshots just as you did (idle)
- Memtest86+ --> 2 complete passes (tests 0 -

- Prime95 --> small FFT 2 hours
- Prime95 blenc 6 hours
- OCCT 2h test (large memory)
- OCCT 15 min test (Linpack test)

Please also capture cpu-z (cpu tab) & HWMonitor during load on all these 4 stress tests.

The idea is to make sure our base settings are stable before pumping speed up. As our limit is most likely to be cpu temperature, we will also evaluate how good our cooling is.

Good Luck!

PS, a little off-topic but nice cable management. I always end up sort of stringing them about

Thanks :-)

I hate wires so I'm always tying them up. Plus I'm always in fear that one of the wires will get caught in a fan.

jsbenson

I'll set everything up later today and get you some screen shots.
