Is there something wrong with my oclock?

post #1 of 6
Thread Starter 
I recently decided to go over my clock and lower my vcore till it is unstable with my overclock.

I am overclocked at 3.4ghz with the Q9550 (stock clock at 2.83ghz)
I previously had my vcore set to 1.1875 and I decided to lower it for heat reduction. I lowered it all the way to the stock vcore settings and ran an hour of prime95 small FFT and then an hour of Blend, 0 errors. Then i decided to run OCCT, Ran for 2 hours 0 errors.

This is great in all, I get around 43C MAX on each core BUT My question is how? I know this is a small oclock but shouldn't it need more voltage then the stock settings?

Also, I have not ran prime95 for anything longer then an hour

If i'm not mistaken, you have your FSB set to 400MHz, from a stock value of 333MHz. In most cases, such an increase would require you to level up a bit the voltage (BTW, 1.875V, is that really accurate), but in some cases it isn't really needed. How did you get to the 3.4GHz mark before? Did you copied from someone or went slowly until you got unstable and then upping the voltage?

To really test the CPU stabilty try to run prime95 on blend for some hours, 24h if you can.
I need upgrades

Why was it that high to begin with, I have always raised the OC then raised the voltage, not the other way around...

Not really,you must have a good chip,if it does'nt crash then the voltage is fine.You should'nt be using 1.875 v-core,lol,you lucky you did'nt fry it.try to keep v-core at 1.50v unless you got the cooling to handle it.when you overclock further dont raise v-core till you need too,even then raise in the smallest increments your mobo will allow until you find stable oc.

Sorry guys, I forgot to put a 1 infront of the 8 lol It was set at 1.1875 I am new to overclocking and I did not copy anyone else. I simply did alot of research and found videos on how to overclock. In my mind 3.4ghz would be a safe reliable overclock. Not to much but it gives it a lil more. So i up'd the bus to 400mhz and I up'd the vcore a lil till i found it stable. However I put it back down to stock and it seems to be fine. I want to run prime95 for 12hours but i always worry its hurting my chip to run that long.

As I said before I ran prime95 on two settings for an hour 0 errors
Then ran OCCT for 2 hours on the high setting 0 errors.
So I guess it come down to running prime95 for a long time?

Prime doesn't hurt your CPU at all as long as your CPU isn't overheating.
