How easy to fry Proccessor?

[nino_brown]

I am thinking of overclocking my 1.4 Athlon Thunderbird, but I am afraid of frying it. I want to know how easy it is to fry a proccessor. Right now as I type this my proccessor reads 43 Celcius. Thanks.

My specs:

MSI K7T Turbo2 MoBo
LeadTek GeForce2 Pro 32 MB
320 MB PC133 SDRAM
5400 RPM Maxtor IDE HD
Volcano 5 CPU fan
AMD 1.4 GHz Athlon Thunderbird
Thermaltake BlueOrb

I would suggest not to overclock it unless you have the correct equipment. I know that if you try to run a AMD without a heatsink it frys but others like celeron just shutdown. So have the proper cooling equipment and check that it works.

:rolleyes:

[Vernon Frazee]

Exactly how much you can push a CPU depends on the individual CPU.

Inside your CPU are millions of tiny little "wires" that electricity flows through. As the electricity is flowing, the resistance in the "wires" causes friction, friction causes heat and too high a heat melts wires.

If you were to magnify one of these tiny "wires", a million times let's say, you would see that they are NOT perfect. There are gouges and nicks all along the edges. These flaws make the "wire" thinner in spots which creates an even greater resistance, more friction and hence higher heat. (Of course that starts heating up everything these flaws too). When one of these "wires" gets too hot it'll start melting in half, right at one of those flawed, thinner areas.

As an example, let's say you had two heavy duty 50 foot extension cords with a 6 foot household (zip) cord inserted between them. Now hook up one end into a 110 volt outlet, the other to a two horsepower table saw and start ripping up some lumber. Before too long (if not already) the zip cord, the thinnest point in the "wire", will melt. (Don't really try this! :)).

This is why it's so hard to pin down exactly how much you can overclock (heat up) a particular CPU. The results will vary depending on how perfect the "wires" are inside it. CPUs with fewer and less severe flaws can be pushed farther.

[nino_brown]

Thanks for the explanation man!! i actually had no idea about that... soo the only problem, really, is heating then? if it had an extremely good way of cooling it down, it could overclock a lot, yes?

[Kurylo]

At the nowadays systems it is hard to fry a CPU:

1. Contemporary CPUs have an implemented temperature reader, which turns off or partially stops the CPU for some time when it gets too hot.

2. Contemporary mobos have a function to monitor these temperatures and to give you a warning sygnal and/or to turn off the system, when the CPU reaches a critical temperatures.

3. Contemporary brand h/s-fans (most of them) have an effective temperature dissipation.

So, I think that you should not worry about the CPU.

[nino_brown]

ok.. this is reassuring.. umm.. I have an MSI K7t TURBO2 MoBo and a 1.4 Thunderbird. I was wondering if I have to augment the voltage? or is that automatic?

[Kurylo]

If there are not any textx in your documentation about the CPU VCore voltage adjustment (no matter, by BIOS or by jumpers), then it's the most likely that the mobo should atomatically select it.

[nino_brown]

ok.. i have that.. and it auto detects!! sweet!! should i overclock the multiplyer, or the memory clock? or both? and what is the combination for the most cool, and efficient overclocking? thanks

[Kurylo]

Not at all.
You should watch yourself. Try all the combinations (but use your mind) and test your CPU for temperature and your system for speed. It's very interesting.

[nino_brown]

is a volcano 5 fan enough to keep the cpu from overheating? the fan is the only thing i need to keep it cool, right..?

[Kurylo]

Yes, Volcano 5 should be enough. But give watercooling a try.

[Martingi]

I heard that the did a test to see which processor would fry

without a heatsink, they tests AMD and Pentium 3, the results

were that AMD fried, but Pentium 3 just didn't boot, saving it.



:D

[Kurylo]

The best way to fry your CPU is to raize a VCore voltage more than 10%. ;)

[dopefeedback]

Tom's Harware did a test to see what happens when you take the cooling off the CPU. In short: The P4 slowed down, the P3 froze up but was not damaged, both the AMD's burnt out.

It is well known that AMD has "problems" with their CPU temps, but it is not because they are worse quality than Intel's. It's because they work harder. 42 Degrees Celsius seems like much. A P3 freezes at 38 degrees Celsius.

[Kurylo]

Another stone in the yard of AMD fans. :p

[Kurylo]

And about P3. My CPU is working at 26C without load, and 52C with 100% load using CPUBURN programs. And these 38C are just big ****.

[Alex Iannuzzi]

Looks like nearly all of use have hear of the test they made with the Pentium 3 and AMD.

[Jimstep]

The AMD Athlon Thunderbird 1.4Ghz specs say that the max temp is 95C. My 1.4Ghz runs at about 53C. I've oc to 1564MHz and ran at 63C. Athlon's temps will jump very high very quickly, so you need to be very careful.

As always, you oc at your own risk.

[jake_westmorley]

i reckon in any case, your cpu will lock up before it damages itself too bad. if it locks up, just put the settings back to normal (at worst case, reset the BIOS), and reboot back to normal. is no big problem. my 1GHz athlon runs at 1.22 GHz fine, but any higher will lock up. My temps are OUTRAGEOUSLY high though, 65 degrees under load. heehee <oops>... and no bust CPU yet.
in any case, even with best cooling, there is still a limit you cannot go above with your cpu. overclockability is not solely dependant on heat...
good luck

Jake

[Martingi]

yes i heard about the test throught some IT friends of mind

[dopefeedback]

95 Degrees Celsius? That can't be right.

And another thing. I'm getting sick of this AMD vs Intel nonsense. They both make excellent chips.

[Mshaw213]

The 95 Degrees is right. This is the temperature at which the chip will start to "fry". You will find that the system becomes unstable long before the chip reaches this temperature.

You tend to find that Athlon CPUs run at between 40-60 degrees C depending on the load. From experience, the system tends to become unstable at about the 65 degree mark.

Hope this helps!

[dopefeedback]

Alright.

Hey - I never said I knew what I was talking about!

[Martingi]

I think when the temp hits 60 Degrees Celsius you cpu shutsdown.

[Alex Iannuzzi]

You can use Asus programs to make it to any Degree you want.

[Jimstep]

Athlon's won't shutdown at 60C. I'm running at 63C as I write this note. I'm oc my 1.4Ghz to 1562Mhz, though the mobo software says 1571Mhz. Most of the time, it runs at 59C. The temps fluctuate depending on application.

[missiveusa]

43C isn't bad for an Athlon 1.4 GHz, which tend to run hotter than the lower 1GHz+ T'birds. If you are going to OC, I would suggest two case fans, one in front for intake, one in rear for exhaust (in addition to PSUnit fan. Try to keep temps below the 50C mark. Risk is low as long as you don't mess with the voltage settings. Good luck.

[ivan of ASEC]

Keep your core voltage below 1.8, above 1.9 can cause meltdown.
Now the xp's will melt down by over heating but the t-bird's lock up befor perminant damage is caused
:D

[kimmage]

A friend of mine has the 1.4gig t/bird with a H/S & fan recommended buy AMD on their site (taisol i think). Over this summer, even though it was in the coolest room in the house (still 40C) the cpu averages between 56 an 62 most of the time. Tried to run seti@home on it and the temps went to 70+ without error but we didn't think it wise to push it that far so needless to say, seti isn't running on it.

You'll probably say that the voltage is set too high. This isn't the case. The m/b is a gigabyte GA-7DXR. Unfortunately the low voltage switches that should be on the board aren't there (just a blank spot with solder holes). If the swithches had been there, maybe we could choose a lower voltage as its though the bios is set to the lowest setting it can go of 1.75v. We're considering trying a different h/s fan, but at the moment it isn't an issue.

I just bought an athlon thunderbird 1.4 with a k7t turbo-r Limeted 6330, did anyone else get theirs as a package at frys electronics, its like everyones got one.

Anyhow I want to overclock my chip also, and Ive stumbled upon some settings in the bios that I want to change but am afraid to, first the voltage, which seems like a bad idea for now, then the overclock ratio, i have like X5 and X5.5, what will this give me?


then ive got over clock by mhz, set at 100, i think if i put 101 that will give me 1 mhz more right?

help is much appreciated, and thanks for the support.

Do you have the 1.4Ghz 200 or 266? If you have the 266, then set you motherboard to 133MhzFSB. It's a jumper that needs to be removed to get this speed.

At 100Mhz FSB, your multiplier defaults to 14. 14 x 100Mhz = 1400Mhz.

If you set the FSB to 133Mhz, then the multiplier defaults to 10.5. 10.5 x 133Mhz = 1400Mhz(1396.5, but its rounded for our purposes).

You can adjust either the FSB or the multiplier.

Let's say you start with 100Mhz FSB and you use the default multiplier. If you up the FSB to 105, then your processor will running at 105Mhz x 14 = 1470Mhz.

On that board, if you use the jumper for 100Mhz, your range will be from 100 to 132.

If you remove the jumper, then the range is 133 to 199.

When you overclock beyond a certain point, then you will need to raise the voltage. You will know when you need to do this when you system starts getting flaky, or just won't boot.

Be forewarned that you overclock at your own risk. You can damage the motherboard, processor and other devices by doing this.

When you overclock with the FSB, you are also driving the other devices connected to the motherboard faster.

When you overclock with the multiplier, you are only effecting the cpu.

For the multiplier, let's say you leave the FSB at 105, you can set the multiplier to 15 to achieve 15 x 105Mhz = 1575Mhz. At that speed, you will probably be increase your voltage to get stability.

I hope this helps. Good luck!

[malachicaesar]

great, that does help.

I have 200mh fsb i think, im pretty sure acutually. Regardless when i tried taking off the fsb 100/133 jumper all hell broke loose. So thats not available to me I guess.

Get this, im running winxp. i right click on my computer, and it says I have an athlon 1.06ghz. and thats after I went into the bios and said "load enhanced settings". before it said 1.05 ghz. so my 1.4ghz chip is only running at 1060mhz.... my temp is about 167deg F. I put a rule in so my comp will shut down at about 178. I know most processors will go up to 190F.

I want to try raising the multiplier to see what happens to the number im mycomputer. If anyone else has this same board and processor, please tell me what youve done and whats happened.

Again I have an athlon thunderbird 1.4ghz (200mhz bus)
k7t turbo-R limeted edition motherboard with Award bios.
I have an ati radeon agp grphics card
390mb mem,
30gb hd
and a 24x cdr


thanks to all,

i've got a fried PIII 1ghz that burned itself out because I had the fan on upside down. No automatic savior for me.

I was just begining to enjoy it too. sheesh.

[rekrot]

I had built a P3 933 for my neighbor. He recently moved into a neighborhood a couple miles away. Of course, he dropped the computer hard when moving it! :( The answer to how easy is it to fry a processor: Make sure the fan stays on because if it falls off and you try to boot, I don't think it last for 15 seconds because thats how long he left the computer on before pulling the plug and frying the 933. That cheap *** Orb type fan had a lousy clip design and I am the duma** that should of replaced it with a better one. His new "Fry's Special" AMD Duron 1000 for $120 plus a good fan fixed him up for now. Peace, RB :)

[the xenon]

malachicaesar here is what ive:
Athlon 1.4 266 fsb (133x10.5)
volcano 2 h/s+fan
on MSI k7T turbo-r
256 sdram

Its non o/ced temps are @ idle 35C , @ heavy load 53C , and @ normal load 45C

Ok , i tryed o/cing it once and that what I got:
135x10.5 >> worked fine
137x10.5 >> didnt boot
133x11 >> worked fine
135x11 >> worked fine
133x11.5 >> booted but after completing sisoft Sandra cpu benchmark restarted :(

tempreture increased in most cases by a coupl degrees C.
and i didnt even consider increasing the voltage.

regards,

[ShadowBlaster]

I have a PIII at 800Mhz, which is running at, FSB: 133Mhz, and frequency multiplier: 6.0. The fan is the original from Intel, which came with the CPU in the box. The MoBo is a PCCHIPS M754lmr, with an Ali Aladdin TNT2 Chipset (nVidia Core)... so, my question is, can I overclock it? and if so, how?? :confused:
I mean, I think I know how to do it but look, the BIOS provides manual configuration for the multiplier. So I set it up to 6.5 or above, and make a "save and exit" but then when the BIOS restarts, it tells 800Mhz again. I checked it in the BIOS, and it is at 6.5
Now, this MoBo has setting option in the BIOS, and also by jumpers, which one should I modify? both?
I openned the PC, and found that, where there should be some jumpers setting the multiplier, I was ready to change it, but, there were no jumpers! the pins where all open, so I checked the MoBo's manual and there are no such a combination of jumpers (all open)......
I think I should steal some jumpers from my neighbour's PC :D
So tell me, does anyone know whether I can overclock this one or not?
I need more power cause Project 64's sound sounds glitchy, and a friend who's got a PIII at 866 says that it runs just fine on his PC:rolleyes:

I'd appreciate any help from you :)

[Ammok]

malachicaesar

my settings aree 146 x 10.5 to give 1533 mhz for my 1.4 tbird.

You will be safe with 133 x 10.5 to give 1400mhz

[malachicaesar]

know why in my computer it says I got 1.06 ghz? I have a 1.4 chip im sure. Im going to oc it now though, thanks for the help all of you

[Ammok]

The bios defaults to 100mhz, you need to go in and change it to 133mhz FSB. I did this myself and was running at 1ghz for a week before it dawned on me what was happening.

[malachicaesar]

when i set it to 133 mhz fsb it wouldnt run properly
it kept halting in the middle of whatever inconsistently

but thanks for the tip

[Ammok]

Yeah, it might do.

Your memory will also be running off the bus speed and can be set to +33, Host Clock, or -33 so that if your memory was already at +33 and you then put the host clock up to 133 it would now be running at 166. Also check your multiplier setting.

A 1.4 T-bird is manufactured to run at 133mhz so something else must be wrong.

LOL

[Ammok]

Thx Gib,:D

[gibsinep]

LOL to funny

[InnovaZero]

see I don't know if I fried my CPU or not because I don't self test boot, no beeps, etc

Yet the CPU still gets warm at the bottom of the heatsink as if it was trying to work.

Guess I have to wait till I get the new PS to find out.

[Tron]

A Friend of mine wanted to change Mohterboard
but did not remove the termalsticker from his Celeron 500...
He killd it... :eek:



and malachicaesar get a better heatsink!!! ;)

love TRON

To ShadowBlaster:
Almost all P3s, especially after the core revision cC0, have a locked multiplier.

Easy to fry a CPU?

I have an AMD Athlon Thunderbird 1.4 @ 1.68GHz (12*140)
Core Voltage 1.80vdc

Idle temps: 34*C
Load Temps: 51*C

ThermalTake Volcano6 with a 60mm Delta "Black Label" 38cfm fan.
Artic Silver II thermal paste.

This is a good thermal solution as it is not too heavy (weighs less than 400g) and is capable of keeping the CPU cool.

------------------------------

Most modern CPUs when they get too hot ... they become unstable... then they fry.

So if you notice a huge spike in temps... or if the CPU becomes unstable ... SHUTDOWN ... and consider clocking the chip down a little... or getting a better thermal solution.

-----------------------------

Hope that this was of some help.
