celeron 300a @375

[astroman]

hi,

i'm a newbie at overclocking. was wondering if its ok to oc a celeron 300a @375 (4.5x 83) with the original heatsink and fan. how do you test for stability and finally, what's the temperature range when running at overclocked speed. @300 its roughly 36-38 degrees celsius.

Thanks

Heck yeah! But your temp is a little high. How is your cooling. Do u have a case fan blowing in and is your power supply blowing out? And u may consider taking off the heatsink/fan and getting rid of the intel stuff and apply heatsink compound.
Go here to see how www.agnhardware.com/index.cfm?article=/hardwaresection/default.cfm?revid=84

And then u could try to reach 450! Which u probably could with some tweaking.
To test your system run Unreal flyby all nite..and if u have a lockup,,then heat could be the culprit or possible upping the voltage by .5v.

Good Luck!

I wouldn´t use the 83MHz FSB,because u both OC ur AGP bus and ur PCI bus. Actually the AGP runs at 83MHz and the PCI runs 41,6MHz. The normal for AGP is 66 and for PCI is 33, so u could be unlucky and actually fry some of ur things.
Use the 83MHz feature witg precaution!

I have a Celeron 300a@464mhz. I tried 4.5x83mhz.. I will dare not go there again. Twice I stupidly set it to 83mhz. Once I did that, windows booted up fine, unfortunately the Hardrive couldn't take it. When I reboot the computer the hardrive contains 13gs of Corrupted files. Its only a 4.3g HD.. heh. What has happened is that the HD probably ran too hot/or too fast and it ruined the File allocation tables. I had to format the HD and load the OS over(twice... duh) but through Trial and Error, I rather run it at a higher speed. At 100mhz its alot more safer than 83mhz. Since 100mhz the PCI and AGP speeds are exactly the same as 66mhz.
