Pentium 4 550.

Hi, i want to overclock my pentium 4 550 (3.4 Ghz Prescott) and how far do u guys think it wil go? Also how hot can prescotts get before damage is done.

Thanks

CPU-Z pic.

also should i mess with the multiplier? bring it up or down?

I am sure the multiplier is locked upwards but I guess it's also locked downwards on P4s so all you can do is play with the FSB.
If you make 60°C or more (under load) with your current cooler you should also get a new one. Theorically should overclock well but not as well as the 530 or 520.
I bet you're looking for conroe and want to squeeze your 550

I have an old P4 560 clocked at 3.6Ghz, I can push it like 4.2Ghz on air, but you can do better if you have better cooling. And for the mutiplier I believe that all the P4 5xx series can be unlockable, I can unlcok my 560, and you should be able to as well. All P4 6xx series are locked. I hope this help

nah its for a friend. Hes getting a great deal on it so he got one.

Ok thanks. ill play with the FSB then

As you can see you can push it from 3.4 to 3.6 or more but if 200+ MHz make sense on my 3000+ ( it's more than 10% of 1800MHz), it won't change much the things for a 3.4GHz CPU (it's less than 6% while 8-10% is considered the minimum reasonable gain form OCing.

4GHz+ with good cooling. Prescotts run hot, but I'd be worried about a temp over 60C. Low to mid-50s is an okay temperature.

True... but a Prescott will not throttle till near 80C, but it is not difficult to keep it below 60C

a vantec 92mm 119cfm fan will keep it cool.

a vantec 92mm 119cfm fan will keep it cool.Yep, and it will p*ss off your neighbours too, as they think you have a jet engine in your comp.room. 8O I suspect getting over 4.0 will take some MAJOR cooling, but 3.8-3.9 should be no probs, with good case airflow. Prescott will not "suffer" with over 60C, they have a great tolerance for heat...but as everyone has said try to keep it below 60C-65C. Make sure you have some fans blowing on the MOSFETS, and even your HD as they'll get nice and toasty warm and case temps can climb. GL

PS. Let us know how you make out.

will do. btw its in a shuttle case so i think 119 cfm shoudl cool the whole danm thing.

A Prescott in a shuttle case is a bad idea. Get a really good cooler if you want to overclock that f*cker. I had a P4 540 in an HP case with only a rear fan, and the CPU and mobo fried.

supposedly the Shuttle ICE cooler is pretty good.
