ok i have a new adm xp 1800
cpu temp is 48c / 118 f running with a crazy pc's dr. thermal extreme
the factory heat sink ran at 59c/138 f
i was wanting to know is this temp to high what sould it be running at
48 still seems high to me could there be some thing wrong with
the cpu its self or the mother board some times it frezes up i
have tryed 3 os win me ,2000,xp home on 2 differnt hd and all
drivers are up to date
the cpu core voltage jumps a round to betwean 1.76 and 1.78
and all of the other voltage read outs jump a round a bit too
this is a new built system


biostar mb m7ib-a
adm xp 1800
nec 7900 cd-rw
80 gb hd maxtor
tnt 2 m64
350 watt power supply

thanks for your help

Those temps are a bit on the high side but the cooler you are using is a good one and should be cooling the cpu better than that. Here's a few ideas:

You do have thermal compound between the cpu and heatsink, right?
It should be a thin-even layer. Too much or too little has an effect on heat also.
How are you getting temps? Mobo monitor isn't always accurate.
Temps do run higher on some motherboards. I run at 1800+ speed and rarely get temps above 100 F.

I doubt heat is causing the lock-ups since those temps are acceptable according to amd. But it's still a posibility. Although me thinks it has something to do with the voltages jumping around. That ain't right at all.

Try to update to the newest bios and check biostar's website faqs or support section for this problem. If the voltage problems still perisist then unless someone has a better solution I suggest you rma that motherboard.

You might try running with no other peripherals to see if any are causing that voltage change. But I think it's motherboard related.

Also try running with the side panel off, just to see if heat is an issue.

I got a 1800+ with MSI mobo. used several sinks. I could not belive the cpu temps even when i had a 1700XP. This is my experiances. with the older unlocked t.bird 1200 unlocked with a mid heat sink and fan i were getting around 35 deg in hot weather and 27 deg in cold wether. ran that cpu at 1400+ full stress was around 30deg or so .

I moved to a smaller case for my xp's and changed mobo's. the Gigabyte reported 120f on the 1700 not even o\clocked. me $hit my pants cos i thought xp's ran cooler i ran the cpu at 1700MHz and got around 149f . on the MSI with 1800xp even at 1.85v full stress i get at most 107F dont think some mobo's report the temps correctly.

I just had some voltage dips like Blade said but only on the 3v, everything else seems fine.

example running 1800xp at 1750 1.8v ( don't need that much tho ) running burn in all night my temp got to about 43deg........i mess with both deg c and deg f. my math is not great but i think it would be 112f
small sinks are cr@p had one foe a week testing cos had copper cover. higher temps but no lock ups
mid sinks aer ok cos i put the biggest one on my cpu the other day spending 2 hrs to put 2 fans on it...don't even ask. i still got the same temp results even thou i had a bigger sink and twice the air flow power.

johnwas64317 hope u get things going betterz soon, get loads of fans in ya case it helps a little.

btw on medication so may have typping errors in me post,,,,, valium sucks when u see double he he
Chris.

It could also be that your case has poor ventilation... I'm running a 1700+ at 2000+ speeds 1.66 Ghz full load i'm only running 109f or 43C at stock speed full load is 96F Using a coolermaster heatpipe. Its all in a Antec/Chieftec 1030B case with 4 sunon 80's moving air in and out...

Gigabyte boards have been known to have higher readouts than other boards. When I took my processor off the other day, I saw the temp diode. It sure seemed like it touched the core, which is one reason it would be so high.

there is a thin layer of artic 3 heat sink compond i all ways keep
the case open both sides and the temp in the room is adout 65 f and i tryed
putting a box fan blowing in to the case temp droped 1 c
and the readings are coming from the mobo sensres in the bios and
some thing call winbond hardware doc. all of the voltage are jumping a bit
and the bios are up to date i think you may be right about the mobo
blade seeings how i am back on the web i think i will get a new mobo
i was thinking about a abit kr7a
or any suggestion would be helpful

thanks for the help
btw sorry bout the spelling
i have no excuse but i kwit school is the 5 grade

I'm running a 1700+ xp on a Biostar M7VIB board

Vcore 1.73
+3.3v about read 3.31 and 3.33
+5v about 4.84 up to 4.89
+12v about 11.80 and 11.86
-12 about -12.11 to -11.86
-5 about -5.14 to -5.04


battery steady 3.25
cpu fan 5,444 to 5,625

CPU temp 63C

This was using Winbond, which came with the Biostar board.

Don't know if my system is actually running right, but thats my readings for comparision. Don't know why the voltages jump around so much. is that normal? Not doing anything but jumping from explorer to winbond and back, and of course got the modem connected to the net.

Would that be a decent temp for the CPU? Using the Biostar onboard readings, don't have any better method available.

Any Idea what OSD is? It stops responding sometimes when I am booted on my other drive and locks the system, but when I end task on it my system seems to be working agian. Modem ain't working worth a hoot on the other drive, but works pretty good when I boot off this drive. Don't know if that is just a driver problem, or if it has to do with the OSD crash.


Will be making mods soon.

Damn reading this thread has really made my love my Alpha 8045 and Antec SX840 case. Wiht my XP1700@ 1570Mhz running SETI all day my temps are 23 case 36 CPU

63C sound like there is no thermal tape or compound between the chip and the heatsink... The Voltages will vary a little yours ain't moving enough to even worry about... But i would be checking into the reason why you chip is running 63c that is WAY too hot. My 1700+ overclocked to almost 2100+ speeds is only runing 41C under a full laod of SETI.

I am running an xp1800 on an MSI k7t266pro

my HSF is a thermaltake volcano 6cu with some antec silver on it
my temps hold steady between 35-43c

Thanks guys.

I will look into the temp with something acurate and see what to do about it!

If you saw some of my other posts, I have had some errors and several people mentioned temps.
Never knew what was a good temp thoug, not into Celceus, heck don't even know how to spell it!

I just checked and right now I am running 58 Cel.. System been on all day. I did read something about mother board sensors not being accurate. Thats what I am using, only thing available right now, winbond and a biostar M/B!

Temp in the house is a wild one too, no air and using wood heat, so in the day it is hot in this trailer at times, and sometimes cold, but not enough to worry about building a fire. Just depends on the days this time of year. Summer it gets to about 100 F at times though.

Glad to know the volts are ok, was wondering about them jumping around a little like that.

What is a normal case reading, and how would I check the CPU temps with another sensor?

Am thinking about a window and lights, maybe some custom rails for the case inside. Had thought about using a indoor outdoor thermometor inside the case. One with the copper tube and bulb sensor on the end. Problem is, I think just tucking it into the heat sink would not give a true reading either, fan would cool it too. Also about the same with my other thoughts on checking CPU temps, heat sink and fan temps is what I would be getting, not true CPU temps, so a bad thermal conection to the cpu would let it be hot while getting a cooler heatsink reading becuase it would not be sucking up the heat.

I am planning to mod everything anyway, soon! Building another system for family use, then I can experiment with mine for awhile

That seems a bit high but realize every mb has a different placement for the pickup of the heat readout.

I have an 1800 mildly overclocked that went about 40c tops on my epox 8k7a but is now on my ga 7dxr which has a closer thermal diode to the cpu but goes to 38c tops on it because of the alpha hs.

I'm not really familiar with your hs but you could try reseating it and check to make sure you have enough grease for a good contact.

My XP's run about 5c cooler than my old Tbird.

You might try http://www.amdmb.com and go to their forums for more info from people with your same mb.
