First overclock...is this safe?

[imported_MSX]

Hi everyone,

I just recently upgraded from a 1.8GHz Celeron (ugh) to a 3.0GHz 631 P4 (Cedar Mill), what a difference.

My BIOS lets me edit the clock speed, and default is 200mhz (200 x 15 = 3.0ghz). I set it to 220mhz, which is 3.3Ghz...I'm using a stock intel HSF, which cools pretty well I guess. I'm using a trial version of Hardware sensors monitor 4.2 (is there any freeware app for this type of stuff?), and it says my CPU's temp is around 27°/28°C, which is good (I think?), and when I'm encoding video it shoots up to around 38°/39°C.

I was wondering if it's safe to overclock from 3.0 to 3.3 with the stock HSF? I've read a lot about the Cedar Mill cores and I've learned they run cooler than most other cores, but I was just wondering and being cautious.

I know you'll probably laugh at me, and that's fine, heh. I think I'm going to restart and go into the BIOS and change it back to the default 200mhz clock until I get an answer.

Thanks!
Nate

You're quite alright, up to about 60°C. From there, you'll have to see whether you have problems or not. Of course, it's an Intel chip, so it will throttle. That means work for a percentage of the time, then not work for a percentage of the time, to keep itself from being damaged by the heat. AMD chips don't do that, the motherboard just shuts the entire system down.

And, yes, there is something that's great for monitoring your entire system: SpeedFan. And it's freeware, not a trial. Just click on "SpeedFan 4.29". Strangely enough, that's there download link.

Thanks for the quick reply! It's very appreciated. Also thanks for that link, great program! Not a complaint, but it doesn't specify what Temp1/Temp2/Temp3 are for, but I think I've figured them out (Temp1 is CPU since it's @ 26°C..right?).

Also, good to hear it...60°C, that sounds really hot. So in theory I should be safe to use stock HSF at maybe 3.6GHz? I want to try 3.6 or 3.8, but I don't want to risk it...I'm being a sissy haha.

EDIT: Figured out how to relabel the Temp1 to something else.

Well, I have version 4.28, and my cpu temp is Temp 2, and my chipset is Temp 3. Temp 1 is most likely power supply, but I'm not sure, since it's not high, either.

For my Temp 3, it says -55C..errr...going on a hunch, I think that might be wrong, but I'm not sure.

EDIT: I ran that share app (Hmonitor), and it says CPU is the same temperature as Temp 1 on SpeedFan, and the system/mobo is the same as Temp 2 on SpeedFan. I guess since we have different mobo's the temps are switched?

yeah you can edit the names

go into the directory, and open the config file 'speedfansens'

browse to the temp1 value and change the 'name = tothenameyouwant' - and you're done 🙂



also, are you sure temp1 is the cpu? in 4.29 there is a new entry 'core'... i am not sure which value is the correct temperature... temp1 behaves as though it is the CPU (eg gets a lot larger when priming etc...) but so does core :/

Throttling doesn't kick in until around 72c on stock voltage. The stock intel heatsink isn't all that great for higher overclocks, but it's plenty for a mild overclock on a single core. With a decent heatsink, such as the scythe ninja, you could likely get your cedar mill over 4ghz pretty easily depending on your motherboard/ram.

Hi everyone,

frizzl, actually I'm not sure, is temp2 your CPU temp?

Also, the morning of my post, my roommate had a sissy fit and actually kicked the computer like 3 times. I tried booting it up but it wouldn't so I went to bed. When I woke up it booted fine, but now it's reading temp1 as idling at 50-56c, and under load around 60-65c. I think this might not be good, anyone give me a recommendation?

I think the next purchases I'm making will be an aftermarket HSF and a case fan (the only fans I have are one built in to the PSU and the fan on the CPU...I know that's not good, right?).

Thanks everyone,
Nate
