Is this a sign of an unstable overclock?

post #1 of 8
Thread Starter 
After about 2 hours of Prime95, my computer was running fine.

4.5GHz w/ -0.015V.

So I decided to use it. After a couple hours of just browsing, my computer completely locked up, and after 5 minutes, my mouse began to respond, only to lock up again. I restarted it, and 5 hours later it happened again.

//./root/CIMV2
SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage > 99
0x80041003

Is the event in event viewer around the time of the lockup.

It is hard to help with questions when people don’t know what hardware you have. Could you follow the instructions in the link below to get your rig in your posts?
http://www.overclock.net/t/1258253/how-to-put-your-rig-in-your-sig

I can’t answer that specific answer, but if I know your hardware I can recommend an oc guide here so you can check to see if your bios settings are correct for your oc.

For some reason I didn't think it was necessary. Sorry.

I have updated my details. I followed this guide:

http://www.overclock.net/t/1198504/complete-overclocking-guide-sandy-bridge-ivy-bridge-asrock-edition#

Using option 1:
Quote:
Offset Mode: Your CPU will use VERY LITTLE voltage and speed when idling, ANYTIME you idle. (Even browsing can be considered idling.)
Enhanced Halt State (C1E): Enabled
CPU C3 State Support: Disabled
CPU C6 State Support: Disabled
Package C State Support: Disabled

Thanks, that will help a lot whenever you are asking questions. Unfortunately my knowledge is limited to Ivy chips, so there isn’t much help I can give on Sandy – sorry. I will tell you that you will get much more help by asking questions in threads that are followed by a lot of people rather than starting a new thread. My best advice is ask your question in that oc guide you linked, a lot of people follow that.

As for Prime95, I recommend running it for 12 hours with 90% of your available ram. That is more than that guide recommends, but based on my experience 2 hours of Prime95 may not be enough so more vCore could be required.

Not familiar with offset voltages, but find out what your voltage equates to. Could be something simple as more VCORE. Might want to try using a definitive voltage instead of offset, it's a lot easier to work with, IMO.

To quicken the process, download Intel Burn Test. Run it on Maximum, see if you can do 10 passes without BSOD or crash/freeze. If it BSOD's make sure you write down the code.

this, +1 for ditch offset voltage. you can go back once you find out what is stable for your rig, use manual to determine your best overclock.

also, unless your into saving the planet (nothing wrong with that) or keeping your hardware for 5 years, I wouldn't even go back to offset voltage. I leave mine @1.384 all day. so far so good.

this problem could be caused by your OC, it could also be a software problem though. try upping the voltage for your OC (if its safe), or underclocking and see if that fixes it. try running a different browser for a bit if you find this problem persists after the above to rule out a problem with your browser. my ie has problems all the time with locking up, dead tabs, etc.

I lowered voltage for temps. is it safe to set 1.375 VCore all the time?

as long as your temps are ok, if its hot or your computer is full of dust, or your chip runs really not, then maybe not. the actual voltage is totally safe for your chip, yes, provided it doesn't get too hot.

you shouldn't go much over 80 degrees when stress testing. ive seen mine hit >90 without vaporising so you've got a fairly wide buffer zone. kickin on prime95 blend now to see how hot mine gets full of dust with crappy TIM application. so it goes to about 60 right now, probably would make 65 after some time. and its reasonably warm out and my noctua is PACKED with dust. like I don't even think air is going through it.

so after further investigation, its unlikely you will have temp problems at that voltage.

HT enabled?

* I will edit that this is @ 4.4 GHz, and adding multi adds heat, so like, 1.375 @ 5GHz is a different story temperature wise, just keep an eye on your temps. nothing is a "safe" voltage if its too hot.
