Hello I have just bought a Q9450. Installed it, made sure the FAN was down etc.. Then when I booted it, it told me i need a BIOS update to "Use it at full power". So when I got to the log in screen my computer power off (Just cut out). I went into the BIOS settings and my FSB is running at 1777mhz. Does anyone know why?

previous overclock that's not been reset?

EDIT: Just set it back down manually in the BIOS
May 13, 2008 3:01:41 PM

No overclocks at all. This is a new chip and i did not overclock the old one.

Update the BIOS ? ussually when a bios does that, really needs a update recognize the cpus. Just an idea .
May 13, 2008 3:03:57 PM

Yeah i'm going to try that now. Anyother ideas?

On the asus website there are loads of different files to download. Do I download the one that adds support to new CPUs or just download the latest one?
Sorry if this is a stupid question I have never done this before...
EDIT: My motherboard is the Asus Maximus Forumla. Can anyone link me to the software that will check and update the BIOS for me?

This should be latest BIOS for your board
http://dlsvr03.asus.com/pub/ASUS/mb/socket775/Maximus_F...

Version 1201 2008/05/04 update

From the Asus website. Im to lazy to figure the site out to see if/where the cpu support list is for the board but that is the latest BIOS for your board.

Thanks Someguy7. If the old BIOS thought the CPU ran at 1777FSB and caused it to overheat to a point where it cut out. Whos fault would that be if the CPU was broke?

It would be your fault. It should be fine. When a overclock setting is to high for either the cpu or mobo to handle it usually will just shut it self down do to heat or system instability. As long as the old BIOS didnt send way to much voltage into the cpu it should be fine.

I have never even tried to upgrade a cpu myself. With me by the time I end up doing a ugrade I need a new mobo anyways. Others who have experience with this way be able to shed some light. Not sure if windows handles the switch fine or if it needs a clean install to properly deal with the newer tech and more cores of your new cpu. If the bios uprade doesnt solve all the issues that would be my next suggestion to look into

The person who ignored the "UPDATE BIOS" message!


But seriously, update your BIOS and that may fix all your issues.
May 13, 2008 6:17:45 PM

It said I only had to update if I wanted full power not if I didn't want a fire! :)  Now I knew I needed the files of the intrenet so I decided to boot up and get the files. Anyway I had to install old CPU boot up, get files. Then install the new one again and update. Anyway I did this and my system is still way too hot. My South bridge is running at 49C! Is this unsafe? Should I buy a better case? Although CPU is down to 38C now. I only have 1 X 120mm fan.
May 13, 2008 6:27:21 PM

Yes you need good cooling to run a quad, both north and southbridge will run noticeably warmer, and some active cooling is cheap insurance.

May 13, 2008 6:29:44 PM

It still is your fault if anything goes wrong for even putting in a cpu that wasnt supported by the current bios on the board. That 49C is warm. What was the temps on it with the old chip? And what chip did it replace? This is all assumption but when I checked the asus website I think the bios for your quad is a beta, which usally means its a older chipset that doesnt officially support the cpu(by intels standards) and has to overclock itself to run it at default. Like a board/chipset(p965) that was made to support 1066FSB but later on with updates can run the 1333FSB dual and quad cores by overclocking. That may have caused a temp increase on the NB. But your south bridge is hot. You might consider getting more fans especially if you got a video card that produces a good amount of heat. Airflow is always a plus.

Also is your FSB and all the other stuff at the correct settings now?
May 13, 2008 6:38:54 PM

Yes it is right now. But when I run any software that uses alot of CPU power (Like games) my CPU jumps from the 40s to 70C.
The old chip never really went over 52C (1.8 dual core).
I think it is a bit stupid that the motherboard let me continue but did not tell me that it might not be safe.

if its a newer chip it will have Tjunction temp which would shut off ur CPU preventing any damage to be done. I think your chip is safe, just work on that cooling!
May 13, 2008 7:06:53 PM

Yeah I think that is what happened before thank god. But I can not use it at 70C though. I don't know what to do. I know its a fast CPU but I never knew they ran this hot. Would installing some better thermal paste help?

more paste can make it worse if you have enough all ready. Too much will can cause problems, but too little paste can casue the same problems, it a risk you got to take but you can try it, you only need a dime size drop of paste then evenly spred it on the cpu.
May 13, 2008 7:13:58 PM

Yeah but i'm guessing that the paste that comes with the CPU will not be as good as the paste that I can buy from the shops. I'll go to town tomorrow and look for a better heatsink/fan and thermal paste
May 13, 2008 7:16:13 PM

yea thats true the paste you buy is more conductive, buy ur self a small $5 tube of some high quality thermal paste.


P.S. I was thinking it could be ur case is not cooling good enough, how is the cooling on your case? You useing 80mm or 120mm fans?
May 13, 2008 7:22:02 PM

Yep. Any good Temperature Monitoring apps? I'm using the Asus one now and want to see if its any different with a different app.
May 13, 2008 7:23:01 PM

get CoreTemp http://www.alcpu.com/CoreTemp/

core# are the temps where Tjunction (Tj. Max) is the temp set to where your CPU shutt off to prevent damage.
May 13, 2008 7:28:23 PM

Oh dear.... It must be incorrect.
Core 0 79C
Core1 77C
Core 2 88C
Core 3 90C
May 13, 2008 7:28:40 PM

p.s. Open the case and clean the heatsink for the cpu, it should drop the temps.
May 13, 2008 7:30:01 PM

Its like 5 hours old :(

sounds like thermal paste to me, if the case if cool but CPU still overheat with new heat sink. it got to be the paste cant think of anything else atm.


Is the heat sink installed properly? Is it locked down?
May 13, 2008 7:36:14 PM

Another one is saying the same thing. :( 
May 13, 2008 7:46:35 PM

im geting: on a Intel Core2 Duo CPU E6700 @ 2.66Ghz. (Not OCed) (running on 1.3volts)

TJ MAX: 85C
Core#0: 30C
Core#1: 30C

then that has to be the right readings :( 
May 13, 2008 7:55:47 PM

My TJ max is 105C. I just double checked the fan it is seated right. There are alot of different threads around the internet with the quads running too high. I'll see what they are like tomorrow when I get a better heatsink. One 120mm fan just does not cut it.

If its a common problem with quad core then there a good chance someone has all ready found the solution to your problem just do some research :D

Maybe the thermal paste was already dry in the box. Would that cause they high temps if the paste was already dry when I got it out of the box?
May 14, 2008 2:18:37 AM

yeah it would cause severe problems if the thermal paste was already dry, b/c then it would not make good contact with the CPU...
May 14, 2008 4:20:31 AM

just update your BIOS. your old one probably didnt support your processor.

Intel doesn't use a paste, it's a pad. It doesn't dry out too easily.
Depending on the package, Intel sometimes puts a thin film over the pad. It's clear plastic. Did you see something like that? Did you remove it?
May 14, 2008 8:22:39 PM

No it had paste on it i'm sure...

Anyway I have cooled it down a bit (Although it is still hot).

May 15, 2008 4:57:23 PM

upgrade to water cooling? water cooling for a CPU is more affordable now a days. :)  Or maybe call Intel and tell them wtf going on with your CPU u just payed **** load of money for!! Im shore they can help you more then that guy you took it too.
May 15, 2008 5:27:11 PM

The man in the shop said that they have a temp reading inside the CPU and will be able to tell its been running hot and will not help me.
May 15, 2008 5:56:51 PM

are you serious that sucks?
May 15, 2008 9:56:57 PM

You got owned by that guy at the shop btw.


Have you tried Realtemp? It uses the correct (we think) numbers for the 45nm.
May 16, 2008 2:30:52 AM

He said overclocking was a waste of time and will decrease your CPU life to months. But he thought it was ok to have my CPU running at 40C in the bios...
Yes i'm using realtemp. I'll phone intel tomorrow anyway and tell them about how hot my CPU is running. I'll see what they have to say about it.
May 19, 2008 9:07:13 AM

Looking at real temp I have seen that my temperature never goes above 45 and never goes below 35C. There must be something wrong because its always at 39-40C. Even under stress. Why would it do this? Are my sensors dead or something? Why are core temp and real temp showing 10 - 11 C difference in temperature? I don't know which one to trust. I'm not playing any games until I can fix this issue and its really annoying.
May 19, 2008 11:30:31 AM

ask CompuTronix he a expert when it comes to cpu temps. He the one that wrote the temp guide for CPUs on this web site.
May 19, 2008 3:14:15 PM

RealTemp and CoreTemp report the temperature right at the core of each CPU, whereas your BIOS and the overall CPU temp comes from a sensor located under the CPU socket of your motherboard. This is why you get different temperature readings. The temperature of each core in your multi-core proc will vary, by as much as 15 degrees C, thats normal, and nothing to be concerned with.

As I dont own any Core2 procs, I dont know what the normal operating temps should be, but 35-45 from realtemp sounds fairly reasonable. A quick check would be to disconnect power from the fan on your heatsink and see what temps you get then, if they rise considerably, the sensor works, if not, something may be wrong.

On a side note, I think I would find a new computer shop, sounds like the one you have been visiting is not the greatest from a customer service standpoint.
O and I forgot hes lying to you, Intel has no way to tell how hot that proccessor has been.
May 19, 2008 9:01:44 PM

Thanks for the information. The overall temperature was ok using the asus software (Have been warned not to use that now though). It even went into the 20Cs sometimes. Its the core temperature software thats showing high temperatures.

EDIT: I got a reply of Intel after I emailed them about the high temperature and they said "Since your processor is running below 71.4 degrees Celsius it means that the processor is running under specification so there is no reason to worry about the temperature of your processor." Although i'm no expert I think that 60C will greatly shorten the life of the CPU.
May 20, 2008 12:57:30 AM

I don't OC much, but I've never had a processor die on me, it's always been something else. I've had a couple motherboards die, hard drives die, northbridge fan, but never a processor.

What are you using to base your opinion off of? A gut feeling? LOL. Intel specs guarantee you at least 3 years, and more that likely longer.

And in three years your processor will be the punchline of some geeky tech joke.

Remember Prescott processors!? HAHAHAHAHAHAHHAAH!!!
May 20, 2008 2:07:33 PM

I ran the Stress test and according to Core Temp one of the cores hit 70 in less than 2 minutes. I just want to fix the issue because its a joke. I also had plans to overclock but it seems I can't now.
