I have got problems overcloking the q9550and i need serious help and i bagg for help PLEASE . im new to this and im having issues . and don't wna kill the q9550 :(

Normal setting are 333x8.5=2.833 vcore= 1.208 is that high???? :??: and temp around 49/38/43/42 idile << thats all on auto setting on the bios didn't touch any thing just disabled the spectrum thing and c1e or whatever that lower the multiplier on idile . <manufacturers setting>

I have clocked the q9550 to 3.2ghz and i have crap colling .
well my seting for q9550 on bios was

376x8.5 = 3.204 vcore on 1.256 taht on auto setting tho by the cpu

and that all i have change and everything on auto

after i do a stability test . The cores get HOT and it say its to hot and the test stops just on 3minutes and im using OCCT

it goes up to 99/97/98/98 dayum hot

Then i thort i could lower the voltage and i did so and the temp were
78/70/73/73 at the vcore of 1.18 and everything on auto , and think thats stil hot

and dont knw if vcore 1.18 is enough to keep 3.2 stable??? thats what im freaking about now :??:

but i think 3.2 wont be reached without good cooling system . so...

i would like to know what will be the setting in the bios for Q9550 at 3.1ghz and 100% stable

i have no clue what to put the vcore on and all that please help me out i just wanna clock it a bit and i think 3.00ghz will be fine just stable .... and cool at 70s on max load , i just need the settings so plz help me out here . :(


thanks

It is best if you get your cooling issue resolved. Clean out the case. Tie down the cables for better airflow. Dont clutter up the case! Get a decent CPU cooler instead of using stock cooler. That is probably what you need to do first before you overclock

well yeai gues your right , ithe comps all clean and ables are fine its just the fans on stockk...
well i think the vcore are to high for the stock q9550 at 1.21 <2.83> do u think so .... should i lower it or it wont be stable ,, thats the factory setting , tho and ones i did so and the temperture when alot down , but i changed it back because i thort it mite create issues .

Dont do anything more with overclocking till you get your cooling sorted out. I have the same mobo, cpu and i found this guide to be great http://www.computerlounge.co.nz/forum/Default.aspx?g=posts&t=50 . Its specific to the q9550 and p5q pro.

No two cpu's/ mobo's oc the same so what you need to get stable will be different than me. I personally needed 1.33 vcore and 1.36 nb voltage to get burntest occt stable @ 3.4. I have very good cooling however and at full load it never goes above 67c.

Once you find what voltage makes it stable dial it back till you find the minimum voltages needed to be stable.

It is different for every CPU. My stock voltage was 1.25 for my Q9550 when I left on auto. I downloaded coretemp to verify my CPU VID. Coretemp shows the same VID = 1.25. I found out I can run my cpu at 3.5 Ghz at that voltage. I can also run it at slower speed with lower voltage.


But as anyone in the forum will tell you, you will get different results with every CPU and Mobo combo. You definitely need to fix your cooling before you OC.
 
I have a Q6600 and a Q9550. The stock Q6600 HSF was OK for a 20 -25% OC (to 3.0 GHz.). The 9550 HSF is about 1/2 the size of the 6600's. It's like Intel went from a pretty decent HSF for a Q6600 to something that was no bigger than it needed to be to run at stock speed for a Q9550.

The first thing you need to do is fix your cooling. The Xigmatek HDT S-1283 is reportedly a very good HSF that is not too expensive.

With a good HSF and decent case airflow, you should have no problem runing at 3.4 GHz.
