1.4GHZ AThlon heat problem SOLVED!

[SuperCyrix]

@1.4 GHZ 39C was a tad too high.

but!
with the voltage set to 1.73V and multiplier at 7.5 yielding a jaw dropping underclock of 400MHZ, the cpu now
stays very cool 35C (3C below system temp) at 1GHZ. Should I try lower?

 

[deerslayer]

Whatever floats your boat. Generally I like to overclock my processors

No. 39c is already rediculously low for that processor. YOu should put it back to stock speeds and stop making baby jesus cry.

ur heat problem is solved, but now u have a mhz problem.

 

[N2Ohyeah]

And a brain problem

Who UNDERCLOCKS!! their CPU by 400MHz just to loose 5C off an already low temp?
Your crazy.

I just got my TBird 1200 happy @ 1476 again. Yay. 11 x 133 1.92V
Stable as a rock. 42C idle and 45C or so when under load.
1500 is do-able, but the slight performance gain isnt worth the lost stability.

Im surprised how cool it runs (according to MBM) at 0.17V over spec. There isnt any unseen damage being done aslong as its low temp, right?

Low temperatures are a means to one of two ends:
1. noise reduction through the use of quieter fans
2. overclocking
Obviously it's not for overclocking. It seems that it's not for noise reduction since the temp you were getting at stock speeds was just fine and could have handled much less agressive cooling as it is.
There was absolutely no reason to underclock the processor like that unless you happen to have a fetish for numbers in the low 30s. The Tbird 1400 can handle cruising temperatures twice that.
Seriously man, put it back to stock speeds...you're making baby Jesus and myself cry.

This doesn't really fit into the topic of this thread but this is so inaccurate I had to chip in. We have seen time and time again the tempurate on extremely overclocked pentium 4 northwood processors being quite low but permanent damage being done to the processor. The reason for this is voltage. You can have a processor cooled with liquid nitrogen and have it run below freezing but if you set it to 4 volts your processor is dead. Usually, overvolting your processor too much for too long a time will cause you to lose the ability to overclock your processor. Northwood are typically okay up to 1.8 volts but people who run then at 1.85 see loss of speed within months. It is okay to run it slightly over spec but I would be careful. I'm not sure of the saftey margins of the tbird.
Hope that helps!

 

[N2Ohyeah]

Eep !

I mite try knocking it back to 1.87 and see how it goes.

The 1.92 is what MBM claims my mobo is feeding the CPU. Should I trust this voltage?
Its set on 1.85v.... Asus A7V133A with 1010 BIOS. Any ideas?

Thanks fer the warning

 

[Pink0]

It's been a while since I overclocked the tbird. You may well be within your safety range. I'm just not sure. I would get the opinion of someone who's more familiar with this CPU's overclocking limits.

 

[adrian12]

kinda of defeats the purpose of having a 1.4ghz CPU...

 

[Pink0]

Seriously dude, I've got a 1ghz tbird sitting here that you can run on the 200fsb for a blisteringly low 750Mhz!!!! I bet that would be even cooler and you could run it with an even lower voltage! Isn't that amazing!? I'll trade it straight for the 1.4...no wait, that's no fair. I think I'd need some cash besides...man if you have a fetish for low temperatures you bought the wrong processor!

Give him a break guys, he's the same guy who stuck to an MII Cyrix when Intel and AMD were cresting 1GHz...

OMG! Well, if noise is a big concern why don't you use a large 80mm copper heatsink and a low noise panaflo. Your temps will go up but you won't hear a darn thing.

That's right, and that Cyrix MII lives on even today occasionally surfing the web, playin some MP3s, and keeping the room worm.

 

[The_Lurker]

Lol.... 1.4 ghz at 35 is a tad high???> rofl! my 1.4ghz T-Bird idles at 46 degrees and loads at 54

Of course, that is at 1.6ghz 1.85 volts

If i clock it to default, idles at 40, load at 45.

Volcanoe 7 with a YS Tech TMD Fan. It idles and loads lower w/ the Volcano Fan at 5000 RPM. LOUD THOUGH!

 

[MadRat]

Hey SuperCyrix,

My XP1800+ only idles at 31-33ºC and my Duron 1.1GHz idles around the same.

Under full load the XP1800+ rarely exceeds 40ºC but the Duron never passes 36ºC.

Maybe you should just move to a different processor to cut the heat output.

I wanted to upgrade to a XP but Epox says my mb doesn't officially support XP. Although some people claims that the
8KTA3 can run a 1600, 1700XP, I wasn't too sure if it was with the AGIO core everyone got from newegg. Decided to go with a
1.4 which was the sure thing. Probably go for a 1600XP in the near future.

Never know though, Fall is here and Winter is right around the corner. I might just crank that bad boy back up to 1.4GHZ when the time is right. Never hurts to have a 65-72w heat generating source during cold weather. But for now, web surfing dont care about the difference between 1 GHZ or 1.4GHZ nor does any of the other applications I use.
