Serial port card - CPU usage question


Recommended Posts

Guest Jack S

I've got a problem with a serial - USB converter causing my CPU to overheat

during lengthy downloads, resulting in a computer shutdown.

 

If i install a serial port card (w/ driver) to do these downloads, will I

wind up with the same problem?

 

Thanks

Re: Serial port card - CPU usage question

 

You say CPU overheats? You you really mean the whole computer overheats?

Or the the real CPU, which is the processor on the motherboard?

The CPU usage goes to 100 pct during the download, which i assume leads to

overheating, then the computer shutsoff after about 60+ seconds of having

the CPU usage at 100 pct.

Are there any error log enties? Is there a temperature monitor you can

use?

 

Is this a laptop or a desktop system? A standard serial card installed in

a desktop shouldn't require any drivers.

 

A serial-USB converter and its driver shouldn't be causing 100% CPU usage.

Something is seriously wrong with it. Try another one with better drivers.

Are you using ZModem for the download protocol? I notice the same

behavior using built-in or PCI card serial ports. I think it has to do

with the overhead of the protocol.

Re: Serial port card - CPU usage question

 

2 problems,

1 If the CPU dumps/overheats at 100% usage there is something seriously

wrong with the cooling system (dirty fins, inadequate heatsink contact,

fan not up to speed, blocked ports)

 

2. The CPU shouldn't be hitting 100% on a down load. What

service/process is doing this in Task Manager?

This is a hardware shutdown, I don't think win xp gets a chance to write an

error, and i don't know where to look.

I couldn't find any on the Asus install disc. I'm assuming it's temperature,

from high cpu usage. All the fans and case openings are ok.

 

I didn't install the cpu so I don;t know if thermal paste was used right, or

what.

I don't feel like buying another.

It's an application program called "Mapsend", for a Magellan gps.

A computer should be able to withstand 100 percent CPU usage without

anything bad happening. And run that way forever.

 

You need to fix your CPU cooling, as virtually any computing activity

could cause short periods of 100 percent usage. In its current state,

the computer could shut down when you make a change in a lengthy

Microsoft Word document. What you're doing, is like running a computer

with a guillotine positioned above your head.

 

If you fix the CPU cooling, the CPU usage will not present a threat to you.

 

A PCI serial card, can use interrupts for data transfer. That means

zero CPU usage, when no characters are being received or transmitted.

But using such a card, is not a substitute for fixing the cooling

problem. The computer can still shut down, even if you stop using the

USB-serial adapter. And it will shut down, when you least want it to,

with unsaved work in memory.

First correct the overheating issue, checking for the items in

parentheses in the first identified problem below. Since it is a

desktop, this should be a relatively easy task and not require a shop.
