Windows 7: Overclocking Problems

Overclocking Problems Howdy All
To start with this is my sys......

My current specs

Q9550 @ 3.4
Noctua NH-D14
Gigabyte GA-EP45-DS5
Gigabyte Radeon HD 6970 2GB OC Version
DDR2 2x2GB
Corsair TX 750
Various HDD 1TB > 3TB
Benq V2400W LCD Monitor
G19 Keyboard
Razer Mamba 4G Mouse
Windows 7 Ultimate X64

First thing i noticed upon boot was this message
(“display driver stopped responding & has recovered”)


Then

I had noticed that my CPU has gone back to its original state of 2.83Mhz, went into bios to investigate and was greeted with this message....

The system has experienced boot failures because of overclocking or changes of voltages.
last settings in this page does not coincide with current H/W settings.



I have never touched any voltage settings

I changed it back to 8.5x333 and all seems well.

Can anyone shed some light on what to do..




Many Thanks

Did you reset the machine while it was booting to the bios or did you loose power then?

The display driver error is just that. You might try updating you driver.

It reset itself @ that poit.
have updated to 12.2 but no change but then this........

OK,
Small increments.
Got it to 375x8.5= 3.18GHZ ran some stress test and all looks stable and reporting
CPU core under test was 1.2v
DDR 1.89v

Went to the next level 380x8.5 and same test reported a Error @ core#2
And then locked up my system.
back @ 3.18khz and looks stable.
Idle temps mid 30's C
Under 100% load test 45>50's C

If the only way to clock higher would be to adjust voltages as well.
If that's the case i would need help as to what voltages and fsb to aim for.

many thanks

As you begin to fail, increase core voltage in small increments to stabilize. Once you are able to load into Windows you need to run CoreTemp to watch your temps and run Prime95 on Blend for a full pass to test stability. For a 24/7 OC on that chip you should not be going over 70 degrees Celsius.

Ok will do.

many Thanks
