i5 2500k 4.5ghz

I cant seem to get anymore out of the i5 2500k i recently bought.

Im using the asus p8z68v-gen3 board, thermalright silver arrow cooler, 8gb corsair vengeance low profile memory.

using 1.3v 4.5ghz is stable. Whats the maximum i can go to before getting worried. Under full load on prime im getting about 72C with room temperature about 24C.

Voltage wise, 1.425 is what overclockers say:

Temp wise, up to you, I wouldn't be happy with anything over 80degrees

Personnaly Id try reseating the cooler.
Then try 4.6GHz with 1.36v, works fine for me.

Are you using the silver arrow? Just wondered if you used the provided thermal paste. I used artic silver 5.

I've since changed 1.375v for 4.7ghz. For me the temps seem to yoyo up and down using asus ai monitor. Does the same on hwmonitor too.

Would prime95 be a better test than intel burn test? Just looked back at my burn test @4.7ghz failure at 40minutes.

Using prime95 with same settings at the moment.

How come the 'max safe voltage' has been revised? A while ago the recommended was 1.35v and OcUK advised not to exceed 1.38 vcore. Just wondering where the new value of 1.425 has come from?

The old voltage was before SB was released so Pre-Order, now they go by Intels recommended

Ah right. Although I wouldn't want to run with 1.425 24/7 it does give a bit more room to OC when you need the extra boost in the future. Always good to know.

Thats the guide i followed. Prime95 been running just over an hour now at 4.7ghz. Seems to be good enough for me. Dont really want to push it.

Dont fancy reseating the cooler either. Removable motherboard dont help. My hands are still cut up from a few nights ago.

uretsai · 27 Nov 2011 at 00:55

Decided to stay at 4.5ghz, prime95 bsod after about 4hours.
