Overclocking 1.33ghz T-Bird, 1st O/C

[icedogg256]

I have a 1.33ghz T-Bird with I belive AYAHA stepping. I have 6 80mm fans and I just bought 10 more. I have a 400watt ps with 256mb of ddr333. I would like to overclock it to 1.4ghz until I get a 2100+ XP, do you think I shouuld have any trouble with at least 12 fans in there?

When I play UT2003 or WarCraft 3 or GTA3, the system goes up to 54*C, thats the highest I've seen it using fuzzy logic 4, I do have a 4500rpm fan on the heatsink, most of my case fans are 3000rpm. I'd like to o/c it until I get a new cpu, which would probly be next spring or early summer, for Doom 3. Do you think I could o/c it, any tips?
And how high do you think it could go safely?

1.4Ghz?? LOL. You can lower the vcore to 1.7v and still hit 1.4Ghz dude.

 

[icedogg256]

the voltage is at 1.79v, sometime 1.81v. Would that be ok with a 1.4ghz O/C?

It depends on the actual temperatures under load, that will be your limiting factor. All those case fans (6+10 fans?) are too much and unless you know exactly what you are doing when you position them you may be actually be hurting the cooling. Those older CPU's tend to run hotter, but I've been able to use 2.1v on a similar CPU using 2 Delta fans on a big Aluminum HS in a controlled temperature environment (my home office). If you have a 'decent' HS you could probably use about 1.9V. With your stated temperature of 54ºC I can tell that you don't have a good heat sink, this is your limiting factor since you are already threating into dangerous temperatures with no overclock. You state that the HS fan is 4500 RPM, that is a useless figure. You need to know the CFM rating on the fan (cubic feet per minute). This gives an idea of the cooling capacity of the fan, not the revs per minute. I wouldn't overclock your system in its present state unless you are prepared to burn the CPU.

i disagree with the last statement
your mobo will automatically shut off before it can fry itself, or your computer will lock up.
i'd just see what's the max oc you can get on stock voltage before your system becomes unstable
your cpu shouldn't get much hotter if you don't increase the voltage.
i used to have a 1.33GHz t-bird AYHJA 9, and it would run no problems @ 1466MHz @ 1.75V on my EPoX 8K7A.
if my CPU was at 40C, i can run it reliably up to 1.53GHz, but at over 50C, it would become unstable past 1.47GHz.

I agree with the post on number of case fans. Too many = waste of time unles youunderstand how air flow works. Most 1.33 Tbirds reach 1.4 without anything special (140 x 10). To get more you will have to unlock it manually and then run at say 140 x 10.5 or even 140 x 11. But watch your heatsink/cooling setup.

all 1333's i have known are factory unlocked. mine ran 1533mhz at 1.85 volts then to reach 1600 mhz it took 2 volts and water cooling




a good heatsink is needed even then my processor under full load was at 53c.

i just got a amd approved fan and heatsink. Should I go with a Volcano 9 or 8? Or do you guys have a good heatsink around $10-$20 or so?

 

[icedogg256]

heres what my case fans look like.

two on the right cooling the hard drive, top one blowing out, bottom one blowing in.
one on the top blowing air out.
two in the back, bottom one blowing out, top one blowing in.

I am going to put 4 in the front, and 2 in the left side blowing in and out. I don't know which direction they should be blowing. They are about 30cfm or so and 3000rpm.
And my heatsink fan is a micro 60mm, should I just replace it, or replace the heatsink and fan?
I also have 4 holes for fans on the left side of the case, 2 80mm holes, and 2 120mm holes.

i would also consider the AX7 i seen a few for sale in the fs/ft forum here. i know cost is a factor but remember without a good heatsink your processor will run hot

ok, i have like $20 or so, what is more important, a good fan or heatsink? I found a 40.1cfm or so 60mm fan for my heatsink, would that drop the temperature, or should I just get a whole new heatsink/fan combo?

 

[icedogg256]

sorry for posting so much, but I found a $6 fan, $11 with shipping.

Delta Fan: 60x60x25mm 12V 0.48A 5.76W 47dBA 6800RPM 38CFM

I would just unscrew the heatsink fan, which is 60mm, and pop this one on, do you think the temperature would drop with this fan?

 

[icedogg256]

or should I get a 60mm 6800rpm, 40.1cfm fan? which would be better without replacing my heatsink. right now my fan is about 1/2 to 3/4 an inch or so.

 

[Jen]

go with a good heatsink and a decent fan.




Jen

 

[icedogg256]

ok, i'll get a good heatsink fan combo for my future processor. But, if I get a good fan for my t-bird, would I see a decrease in temperature? Because I'd rather get a heatsink/fan combo for a 2100+ XP or so I'm getting next year, and use the fan on my t-bird until I get that chip.

*bump* I can raise the multiplier, I will do it 10.5. Is raising the multiplier easier and safer than raising the fsb, thats what I've heard. This week I'll o/c it to 1.4 or so with 133x10.5.

Just raise the multiplier before you play with the FSB cause you don't know what FSB your system will run at. It's safer anyways as the PCI and AGP speed do not change.

As for the fan, consider getting a Sk7 for a little bit for money. It's well worth it. A 47Dba fan will hurt your ear. Trust me.

 

[icedogg256]

ok, but is the fan on that heatsink 60mm? because I'd buy a new heatsink/fan combo, and then put the new fan on the old heatsink, would that cool the cpu down? or should i just leave it the way it is. Also, I am thinking about adding a 80mm fan onto a 80mm fan for a double fan, both would be blowing the same dirrection like this -)-), would that make the hot air escape faster or not?

and with the heatsink/fan, how high should the temp with 1.4ghz using the multiplier, it goes at 54*C at full load, and I am adding about 6-8 more fans in the case, 30cfm 3000rpm.

 

[CraigRT]

My 1.33 T-Bird runs at 10x150 on an MSI K7T Turbo board. (1500MHz) rock solid for the last like year now... 1400 will be a snap.

 

[icedogg256]

ya, but how hot is the cpu at full load?

 

[CraigRT]

around 50 or so
depends on the time of year..

 

[pillage2001]

If you were to get the sk7, I believe you will need a 80 mm fan which cools better and much quieter than what you already have. Anything below 60c for your oc effort is alright.

 

[icedogg256]

alright, so if I get 54-58 or so C at full load, then that should be okay? btw, I plan on putting 4 fans in the front sucking air in, then I'll have 2 fans in the back sucking air out, while 4 fans in the front blow air in cooling the hard drive, and 1 fan on the top blowing hot air out. 1 more question, if I screw on a fan to another fan, like a double fan, would that create a more powerful fan that would blow air out faster or would It just take longer for the air to get out? because I saw a heatsink fan on the screensavers that had a micro fan and a regular fan and they said that it was loud and did the job perfectly, should I add 1 fan to the top fan to create a double fan, or is this a bad idea, or should I just try it and see.

 

[Jen]

i wouldnt stack two fans together hurts the airflow. you will have plenty of fans in the case from what i am reading. noise may be a factor depending on the dba / cfm of the case fans you will be useing.


1400mhz should be easy enough for the processor with even stock voltage. shouldnt have any problems with the processor as long as you stay below 60c as others have noted above. mine was at 54c under load in a room that was 90F plus.

ok, but I have hmonitor and fuzzy logic 4, fuzzy says 54-56*C un ut2003, hmonitor says around 52-53*c. And my pc is in the basement and I life in michigan, so its cold here. Later this week I'll probly post my o/cing experience and speed.
