PC Restarts Automatically After Overclocking

post #1 of 11
Thread Starter 
Hi guys,

I am new to this overclocking process, so please bear with my questions. I recently played around with my PC by overclocking it with the following specs:

CPU Overclock: 4.5Ghz
BCLCK: 180Mhz
SPD Multiplier: 12
Memory Frequency: 2160Mhz
CPU Vcore: 1.5373V
QPI/Vtt: 1.375V
IOH Core: 1.300V
DRAM Voltage: 1.86V

I stress-tested this system with Intel Burn Test for half an hour and everything went well. However, when I left the computer for, say, downloading stuff on with uTorrent or running a screensaver, the PC will automatically restarts itself.

Is there anyway for me to diagnose what causes this problem?

Thanks for your help in advance.

There is something wrong with the overclock. Try lowering ur mem freq as well as the dram voltage and start from there

You're probably getting a BSOD when not around. You need more than 30 minutes of stress testing to confirm stability. Gotta run a 24 hour burn, buddy

Watch that vcore... you're pushing it. Look elsewhere for the problem. As Stallion said, drop your RAM a bit.

Thanks for the tips guys.

I just found out that it was my screensaver that crashes my Windows. I manage to tone down the overclock to 4.50GHz with 1.40volts, memory frequency 2000Mhz, BCLK 166Mhz. Currently running F@H with -smp12 at temperature around 80'C on average, and it's been running for 8 hours without any hiccup. Do you think the temp is running a bit too high when running F@H?

Quick question: is there any significant merit in overclocking your RAM?

80c is certainly on the upper end. What does your look consist of? Any pictures?

i toned down my overclock to 4Ghz at 1.3v. Average temp running F@H is between 63-69'C.
Will this perhaps help?



My further questions are:
1) Will higher CPU overclock result in a better CPU folding?
2) Is there any significant merit in overclocking your RAM?

Why do you have 4 F@H windows open? There is no need for that. Unless that's for your GPU's what are ATI and I would then recommend not folding on them as they hinder your CPU results.

Anyways back on topic. Loosen your ram timings a little bit

One very important thing to remember about setting up windows is turning off the Automatically Restart Option when there is a critical system failure..

To disable this...

Press the Windows Key + Pause/Break Key (The windows key is next to Left Ctrl Key)
Select Advanced System Settings in the window that pops up
Select the Settings Button under the Startup and Recovery Section in the Advanced Tab
Under System Failure uncheck the box that reads Automatically restart.

This will allow you to recieve the BSOD error Message (e.g. The Blue Screen) so you can properly diagnose the problem, make sure you hand write the message down.

The Thing you want to write down is the Error Code..

Example of Error Codes:

0X000000ED UNMOUNTED_BOOT_VOLUME

This way you can properly ask for help on the forums and a profession tech can give you a direct answer on what is wrong, or you can simply google the error code to get directions on how to resolve the error (if possible)...

Overclocking can cause other issues when there is a critical system failure while running a Burn Test (stress testing), on occasions I've had repair my Hard Disc Drive by running the command prompt in a boot disc (Windows Recovery Disk) & typing:

c: chkdsk /f

the /f is critical because this will fix the issue with the hard drive, which is sometimes the error result of the drive being set up in RAID for no apparent reason by overclocking.


Hope this helps...

Loosen your ram timings a little bit is not really advice, that's technical jargon which most people will look at and go huh?

Can you be more specific when offering advice on the forums & try to help everyone who reads the forums by showing them that you can be informative rather than giving a convoluted answer which isn't definitive enough?

thanks for the great tips. that's what i have been trying to write down: the error code, which I previously could not get because Windows will automatically restart after BSOD.

please excuse my ignorance, but how can this be set? is it thru BIOS? when you say 'loosen the RAM timing', what sort of numbers are you looking at?
