Athlon XP 1900+ with A-BIT KT7A-RAID overheat and hang up.

I was trying but always do the same thing.
The procesor start to warm up until the 50 degrees and hang.
I don't know the exact voltage, but in the default settings
say 1,75 and 3,4 (core & i/o)

I try to underclock but, seems to be protected, and it does not let modify the frequency.

I read in the amd and a-bit webs but found nothing.

help?

Heating to 50C is NOT the problem here.  That's WELL WITHIN normal operation parameters.

There is something ELSE wrong here.  Try swapping out your RAM, that's a common problem with system hangs.

Ok, but if I put a ventilator aiming to him at the opened cabinet, does not hang, so I supose that not is the RAM.

The RAM are micron Pc 133.

I'm saying that 50C is NOT HOT for the CPU.  There are other possibilities, however:

1) Your CPU is DEFECTIVE and not working at it should at 50C.  If you are overclocking or otherwise operating this CPU improperly, that could be a factor.

2) Something else in your system is overheating.  RAM, VIDEO, MOTHERBOARD, etc. could all be the problem.  If putting a ventilator helps then I'd guess you have poor CASE ventilation.  Check your power supply fans and also your case fan.

Another question:  When you say 50C do you mean the ambient case temperature or the cpu temperature?   If it's a 50C case temp, that's too hot.

I suppose it's possible the cpu temp. sensor is also off, and that may be causing a reading that's incorrect.  If it were say 10C low in its reading, that means you're really at 60C, which might explain the problems.  

Although your AthlonXP has a maximum internal die temp of 85 - 90C, the reading your bios provides is NOT the internal die temp.  As such most mobo's default to shut down at 65C.

That's another thing you might want to check is the shutdown temperature to make sure it's not set at 50C . . .

jfyi, you might want to get another cooler for your cpu, just to make sure your processor won't overheat, take a look at the coolers at: http://www.zalman.co.kr/usa/product/cnps6000Cu.htm (looking good doesn't it and it will keep your cpu temperature down)

My mother does't have an auto shutdown temperature. But after changing the frecuency of the memories, it start to work well.
They were in SDRAM 8-10ns and I place them in TURBO now. I suppose that it was the underclock of them.

Thanks all!!

I think I know your problem.  Is your motherboard a v1.2 or below?  The little white sticker (usually near the last PCI slot) will tell you.  XP's are only supported by v1.3 and above for KT7A boards (check the ABIT site).  I have a v1.1, and I had to hack my BIOS to support my 1800+.  If this is indeed your problem, and you want that BIOS hack, let me know and I'll track it down for you.

Thanks, I found this site on the web too, I flash the bios, but continue the problem . I think that it's something with the video card (Radeon 9500 pro 128 Mb Original) Because the machine work fine until I wathc a DVD or play a 3D Game like LOTR ROTK, or Max Payne.

Thanks Again!

I had a problem with my 1800+ in my RAID board when I put it in, it looked like this:

Turns out it seems to be a problem w/ the processor and my video card, a Radeon 64MB DDR VIVO.  I switched it out w/ a 16MB ATI card and problem solved.  I cannot figure out why this is happening, I put in a new power supply (upgraded from 250W to 550W) and it's still happening.

Try swapping video cards.

Hi, I see your screenshot in ocforums.com and it's not my case. My machine seems to works great but later if I open a DVD or play a 3d game then it hang up.
I'm gonna sell the KT7A-Raid and buy a new one. You know if the Athlon XP 1900+ 1.75v works with DDR 400 mhz memory?

Glen A.IT Project ManagerCommented:
The cpu you have will work fine with PC3200 (DDR 400MHz) memory.
