PIII 866

I have recently build a PIII system with used parts to use with win98

Asus P3B-F mobo bios 1008 beta 4
PIII 866 cpu running at stock speed (6.5x133)
1x256+2x128mb 133mhz kingston sdrams running at 3-3-3-10
Maxtor 6Y060L0 60gb harddisk
NEC CD-RW NR-9300A
Creative ES1371 sound card
D-link DWL-G520 wireless pci card

my problem is cpu seems to be running at 68C that is app. 154F
any ideas wtf is wrong with the system?

fan mounted properly, thermal paste applied, aftermarket fan and heatsink

I used the same fan with my moms pc it is a pIII 500 with a p2b-f mobo it runs at 27C (80F)

    What program are you getting your temps from?
  2. motherboard monitor 5.3.7.0
  3. Your P3 is a coppermine, and placing the heatsink on them is a pretty tricky task because the core is so small and without a heatspreader, the heatsink will sometimes sit on an edge rather than lay on the whole core. So, first, I'd advice you to make sure it's OK. Then, I think is would be better for you to change the fan on the heatsink because an original P3 heatsink fan is supposed to have been running for about 8 years and I don't think it's healthy to rely on that fan any longer.
  4. Simple procedure.

    Step 1 - READ
    Step 2 - ANSWER

    Anyway,

    Fan is mounted properly heatsink and fan are new.
    I have similar setups running one with 500mhz one with 866 mhz. both are stock speeds.
    500 runs @ 27C 866runs @ 68C

    866 ran @ 70-71C with the stock fan and heatsink.
  5. Any ideas? Anyone?
  6. I'd check the airflow.

    I remember my PIII 800 ran 38-40C idle. 47-48C load.

    But, its dead now, and I could see cracks on the 2 corners of the die.

    I think the packaging for the HSF for PIII's were crap compared to PII's not to mention it still works, but not really being used anymore.

    So, if you could point a house fan at it, with the side or top of the PC case off, see if that helps cool things down. If not, I'd re-check the HSF.
  7. Your not god, or else you would not be asking for help.

    I'm with m25 on this. Double check the heatsink. Make sure that its oriented the correct way. Because the heatsink on the P3 attaches only to the socket and not the motherboard, its possible for it to get put on wrong. Also, make sure you didn't use to much TIM. If you take the heatsink off and see TIM on the die along with the core, then you used to much. (if it doesn't cover all of the core, then you used to little...)

    If it was attached correctly, and the TIM amount was right, then I'm not sure. Perhaps you have bad airflow in your case. Double check the amount of Vcore going to the CPU. (I belive the P3 is supposed to be at 1.6-1.65V) Check to see if you are using any programs to thermally control your CPU fan. (adjust or turn off.)
  8. :oops: . o O (is that PIII a socket or slot type?)
  9. I'm pretty sure socket. The fastest slot P3 I've seen was a 733MHz. I've heard of 1GHz slot xeons, so I guess it could be a slot...
  10. Well.. my coppermine (PIII 800) is the slot type (100FSB). Just wondering what version the OP had. I even saw a PIII 850 I was going to get to replace the PIII 800, like this one.

    But, I don't think its really worth bring that old system back to life. :lol:

    Thinking about it, there were even 133FSB slot, 1ghz PIII.

    Edit:

    LOL, that same place has it cheaper for the PIII 1Ghz 133FSB
  11. They do/did have slot processors that went up to 1 gig. His prob is probably an improperly installed heat sink or case air flow prob. Take off the cover and then check your temps.

    Check out the link to see some slot processors.

  12. That setup is strangely similar to my own backup/secondary rig. I have the same CPU, same hard drive, similar memory, and an ASUS motherboard (CUSL2-C). I also have a SoundBlaster Audigy and an FX5200 (worst purchase I've ever made) in it. I have it overclocked to 1Ghz with a FSB of 154, it's been running at that speed since around mid-2004, completely stable. Good luck with getting that thing down to acceptable temps.
