Noob overclock question

post #1 of 8
Thread Starter 
I have been playing around with the overclock stuff in the bios lately. I know this is a noob question but lets just say you lowered the multipliers for the processor and raised the fsb with of course the voltage.

Would this make the CPU faster in realistic cases rather than raising only the multipliers or the FSB?

Well its all about the final speed of your cpu, lets say you have 14x271=3800MHZ or 10x380=3800MHZ, as you can see the speed becomes the same, the only difference is that you should try to raise your multiplier as much as you can and not fsb until you need to, why? because raising FSB also increases ram speed, HT Link speed, CPUNB Speed, etc unless you want to overclock these too go ahead use the fsb too and find a good combination between the multiplier and fsb to get the desired cpu and the other components speeds. Most motherboards will do the math for you and tell you what the speeds are when you raise or lower your fsb and multiplier.

Watch the temps smile.gif

Anyone more experienced go ahead and correct me if im wrong though.

Thanks I managed to get my AMD Athlon II X2 260 3.2ghz 1.4v to a nice 3.85ghz 1.5v stable a while back and was playing around in the bios settings today to see what else i could do. 115 F max temp on prime 95 for about an hour is that any good? I figure it should be lower considering the cooling i have.

Thats great! the temps are actually quite low for those voltages! You shouldnt worry until the cpu climbs over 55 celsius (131 Fahrenheit)

I would call that a successfull overclock smile.gif

When I was on stock cooling with that OC it was around 125 F I pushed it to 140 F and I stopped. Max temp is around 170 for this CPU. I am running an Antec Kuhler H2O 620 Liquid Cooling System and I figured the temps would be lower.

Most contained watercoolers will let your cpu get hot inorder to stay quiet! so what it means, lets say your radiator fan is at like 1500-1800rpm when at load, the second it reaches a really high temp it may climb to 2500RPM to keep it cool.

Basically your temps are this high because the cooler doesnt need to cool it more, thats why it doesnt get any higher because the cooler wont let it, but if it goes over 55C or so the cooler will really kick in!

Dont worry there is nothing wrong with your cooler, as i said it doesnt cool the cpu more than it needs to.

You might even put a second fan on the other side of the radiator if you are really worried (which you shouldnt be) and do what i did and turn the fan so it sucks air into the case instead of out so it cools the cpu with cold air from the outside of the computer.

you said that the max temp for that cpu is 170 Fahrenheit, though you shouldnt let it go over 131 for safety reasons. some cpus can take very high temperatures and others wont, thats why people like to keep them below 131.
