Is my cpu clocked too high?

Problems:
-occasional restarts (about once every 2 days) only when I am surfing or doing something in windows. Never happens when I am gaming or afk.
-I run prime95 torture test (test a bit of everything) and it fails in less than 5 mins saying something like rounding to 0.5, should be < 0.4, hardware problem
-Everytime I boot up windows, I get the message "An error has occured" and the title is Microsoft Windows


Is this all caused by the OCing? What can I do? I thought it might be a bad window install but do you guys think? If it was CPU, should I raise/lower the voltage? lower fsb? It is really disappointing not being able to run 2.6ghz with a venice.
 
i would increase your voltage and run prime again. that is definately unstable. you want prime95 to run without error for 12 hours. go up to 1.55v or maybe a bit above that. if you still get errors, you have to reduce your oc.
 
does it matter if I increase the voltage with the .025v option or the % option? are they just the same thing but combined for fine tuning?
 
Also, how come my voltage is always a bit lower than what I set it to?
I set it to 1.500 in bios but it reads 1.488 in windows
and just now I upped it to 1.550 in bios but it reads 1.536
 
"ou want prime95 to run without error for 12 hours"


Correction: Make that indefinately. You want prime to run stable without error, period.
 
Well it is much more stable now at 1.536v, no error in prime95 so far and no more start up window error. I'll have to further test this and hope it doesn't overheat with my stock hs/f

no, you can use the % system for more precision if you wish.


BE SURE TO USE A CALCULATOR SO YOU KNOW HOW MUCH JUICE IT IS AFTER MULTIPLICATION!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

random restarts and prime faulure = NOT STABLE. downclock immediatly.
 
What I dont understand is why my cpu is at 35C idle and the PWM IC is around 49C idle? shouldn't the CPU be the hottest thing? what exactly is the PWM IC?

edit: also, does cooler temps help with OCing stability? I thought cooler temperature was needed only to keep you off the limit of around 60C.
 
get a thermalright XP-90/120 or a zalman 7000. Overclocking on the stock hsf is going to limit ur overclock. up the voltages and u can up ur speed. more voltage/speed=heat. Upgrade ur hsf.
 
What I want to know is if getting cooler temperatures is for keeping away from the limit of overheating/reboot or does lower temperatures actually help the cpu become more stable? might be confusing, I want to know if the HS serves a single or double purpose before spending like 60CAN on xp-90+fan
 
hmm ok i'll get the xp-90 tomorrow then... i'll save a few bucks by using one of my 80mm lying around and adjust it to a reasonable sound level

it just sucks how I have to upgrade everything. All I do now is buy things that can be carried over... like a bigger psu, using pci-e, and 939 socket

Should I get some AS5 as well? I got some paste from my silencer 6 that I can use.
 
i know it is the best but do i really need those few degrees? I dont really think it will help stability wise. just trying to save a few bucks... its like $12CAN

To answer your question, the PWM sensor gives you an idea of how hot your power modules are getting. The sensor is on the board, between the CPU and power modules. I believe these things are fine all the way up to 70, but obviously, the cooler they run, the better the chance they will provide stable voltage to the CPU. The XP-90 can be a great help here, since it can be positioned to have air flowing over these modules (at least on my nf3 it can.)
