Abit CPU Protection

[vehbi]

Does Abit NF7-S have the same CPU protection as C.O.P of Asus A7N8X Deluxe?
As far as I know, A7N8X mobo is able to protect the CPU during boot up sequence even though no heatsink is installed. Is NF7-S capable of doing this in the same manner?

Not quiet sure what you mean...but the board does have a CPU throttle as well as an automatic shut off, both of which you can adjust by temp.

What happens if I don't install a heatsink on the CPU and power up the system?

Asus board having C.O.P feature protects the CPU from damage during initial boot sequence and shuts the system down immediately. This kind of feature is also utilized by Soltek boards having ABS 2 (Anti Burning Shield). These are the only two boards that I know having this type of protection.

Thanks.

Welcome To The Forums!!!!!

.....and to the addiction

ABIT CPU H.T.P (Hardware Thermal Protection)

ABIT CPU H.T.P. uses pure hardware detection, which not like others use software detection to prevent CPU overheating. ABIT CPU H.T.P provides more reliable result for customers?investment.

That's what I could find on their site. Why is this feature important to your purchase?

Well, I had one CPU burned just because of the overheat on the CPU. So I would not like to have one anymore. IMO, this is a good selling argument in Turkey for the Asus boards. Of course, this is not going to be the first item that consider while making buying desicion, but it is a good plus anyway.

BTW, which board do you recommend? Asus A7N8X Deluxe v2.0 or Abit NF7-S v2.0.

The only pluses for the Asus are dual LAN, C.O.P, QFan and for the Abit is its excellent O/C capability.

I will use two sticks of Corsair XMS 3200 (2x256 MB) in my system.

Thanks.

Now I understand what you are worried about. The ABIT, as quoted above, has CPU H.T.P. which when enabled in the BIOS you will have protection from overheating so that addresses your real problem.

With regards to NOT having a heatsink & fan attached to your CPU & having the board shutdown, this feature is possible as long as the CPU H.T.P. is enabled since you will be setting a shutdown temperature & the board will power off when it is reached.

The biggest drawback in this particular type of protection that ABIT included is that it is DISABLED by default, meaning if you clear your CMOS it will be disabled. The CPUs HSF RPM sensor is also DISABLED by default but when enabled will shutdown your system when there is no RPM signal from your CPU fan. Both of these fail safe systems will protect you, assuming they are enabled & setup properly, from any problems similar to your last accident.

Thanks Sonny,

So,all in all, it can be said that Abit provides as much reliable CPU h/w protection as Asus/Soltek. I think I will go for Abit mobo.

Only if it is enabled which it isnt by default. You might run into some issues with your Corsair and NF2 systems as the SPD settings that were originally programmed into them would result in a non booting system. Search the forums for similar issues.

The NF7-S 2.0 CPU overheat protection in the BIOS worked for me this weekend. My pump died and it shutdown the system as soon as the cpu temp hit 60c (my setting in BIOS). It kept the system down until the temp went down to ~ 50, then permitted reboot. Then I noticed my pump was dead, so it's back to the SLK800 until my replacement pump arrives later this week.

The ABIT overheat protection is not disabled by default on the NF7-S.

There are actually two locations in the BIOS for overheat protection. One seems to be related to the in-socket thermistor reading, and allows you to set both a warning and shutdown temperature. This one is off by default, I think.

The other location is related to the on-die thermistor, and lets you set a completely separate shutdown temperature. It defaults to 110C if I recall correctly, and can only be set as low as 85C.

Then there's the CPU overheat throttling option - not really sure which thermistor is used for that one.

This is all correct, but the default value is 85C not 110C and the only available temp are 85, 95 and 100C (according to the user manual)

dont bother about this...
abit HAS A GREAT CPU PROTECTION!!!
i bet a duron to a friend of mine if i turn on my computer without heatsink i wll not kill the cpu...
put my new athlon xp , crossed my fingers, and turn it on!!!

the result...
in less than 2 seconds the computer makes a *BEEP* and turn off.
i removed the cpu and look behind to see if the little paper (garanty) is burn but is WHITE... put the cpu again, put my heatsink, and now im writing this (btw, i had it in 2220 mhz (222x10)

Nobody in their right mind should do that. It's just plain reckless no matter the outcome.

 

[vehbi]

Iguanas, brave man. Now you made me feel that Abit board does have a great CPU overtemperature protection. I don't think Asus board has something (C.O.P) better than this.

well, i trust in hadware review sites...
but i admit that i lost a kg when im removing the micro to check it!
i almost dead...
but now, i had a new microprocessor to make another computer

and BTW i wasnt in my best mental conditions.. (too much vodka)
