New to overclocking.

[toexspenceive]

Hey guys I have recently just built my first box and started overclocking. I have been using the overclocking in my BIOS. But i decided to toy with the FSB manually. At 20% overclocked (3.6ghz) with stress test my CPU temp was around 64-67°C max. But when i turned that off and changed the front side bus i was at 3.9ghz and ran at 58-60°C. So my question is why would my temperature drop? Theoretically shouldnt it be higher?

What ever program you used to OC it the first time probably raised the voltages (maybe more than needed), hence the higher temps.

You should stick with manually changing the Bios settings to be safe.

Yes, it should be higher UNLESS the CPU is going way over and automatically reducing speeds. Also what program are you using to tell temps? Use RealTemp.

 

[toexspenceive]

I use Core Temp. Would my CPU still say its at 3.95 even if it really wasnt? But i know that its def. not slowing it down because people say they get my CPU at 4.0 with just air no problem.

I didnt use a program to overclock I just used the overclocking in my BIOS.

What heat sink?

 

[RJR]

Did you just change all the Bios settings manually??

If not, read up on OCing in the guides and stickies to learn about all the different Bios settings that you will need to change. Work it up slowly and stress test (Prime95/OCCT/Intel Burn) in between and always monitor your temps.

If you did, what are your Bios settings?

Thanks, Toexspenceive

What we need is settings like:

vcore: ?
FSB: 437.50
Multiplier: 9
NB voltage: ?
SB voltage: ?
GTL ref: ?
Ram voltage: ?
Speedstep: disabled
Etc...

Also noticed your Ram (DDR2-800) is running at 1050 Mhz with a fsb strap of 5:6. If it's giving you any problems you may want to change the strap to 1:1. That can hold back your OC if the Ram won't OC that far.

They all look fine, would you like any help achieving a particular OC or are you all set??

well i ran a prime95 test and one core had an error after a couple hours or so. So i just reset my cmos and im gonna start all over again and. I'm also going to read up some more about OCing. But thanks for everthing.
