Supahos :
82 is a bit too hot. Try either dropping voltage a bit or frequency. The Lower the voltage the lower your temps. The only reason to add voltage is if it's unstable at a lower one.
ElectrO_90 :
You have a serious problem with your cooler, it should be better than what you are getting. You should make sure it's clean and paste is adequate. Also if you added more paste, which one?
You really don't want to put more than 1.3 in your cpu, and i wouldn't even go that high. Cpu hits melt down when you get 1.3+ and needs decent cooling. You should get 4Ghz without upping the voltage.
I just applied new paste which came with cooler,it's called LC Power.
I applied paste which was as big as grain of rice.
I set voltage at 1.300 (frequency is 4,3Ghz) and now,after 45 minutes of Prime95 I got max temp
83c.
Guys,can you tell me how long should I run Prime95 and when will I see highest max temperature?
Ten minutes typically works well for reaching maximum efficiency, but 83 is quite near the optimal throttle setting. Consider reducing the voltage a bit more.
Supahos :
Usually 10 minutes is sufficient for an air cooler to reach close to maximum, but at 83 it's really near the throttle temperature. Consider reducing the voltage a bit more. I lowered it to 1.270v without any crash after 30 minutes; the temperature was 80°C and I plan to try 1.245v to check stability. You mentioned 10 minutes is enough for max temp, but I ran it for an hour and the temperature kept going up, which is unusual.
They'll increase a bit, but usually you won't stay at full capacity for long periods in everyday situations.
They'll increase a bit but usually you won't stay at full usage for long periods in real life. Overall, if Prime95 runs smoothly for 45 minutes without crashing and temperatures stay under 78°C, it's a stable overclock, isn't it?
P.S
P95 didn't crash, but after restarting my PC I received a message (before BIOS) telling me I could press F1 to enter BIOS or F2 to reset to default. This occurred occasionally, so it might mean the overclock wasn't fully successful.
