not workin 100%

[Graham]

I oc'd my PIII 600e to 798 (133x6). All ok as far as heat concerned (using cpuidle), max temp 32 deg c.
Sometimes after a long time, the machine will reboot, no warning, it will then run normally for ages again.
I can make it reboot (but not immediately) by using fs2000, the heaviest load I can think of, and the temp is still no higher than 32.
Anyone got any ideas?, bios settings etc.

The problem occurs with that particular program or just any programs with heavy load? Please provide more info about mobo and cooling system. Also, check CPU thermistor whether it reads accurately.

The system is..

QDI Advance 10 (via apollo 133a)Award BIOS
PIII 600e (at 6x133)Standard HS/Fan with compound and copper shims.
Hercules Dynamite TNT (not clocked)
128 meg Kingston 133MHz ram
SBlaster pci128
Seagate, and IBM drives both 7200r/m (Cooled)
HP SCSI scanner card
10 base T ethernet card (cheapie)
Asus as400 CD rom
Mitsumi 4802 CDR-W

Plus the usual, printers etc.


The system reboots occasionally, for no apparent reason, the only thing that will do it ALMOST for certain is FS2000, i havn't tried too much else (increasing fs2000 framerates is an aim of the overclock and it works, fs2k needs grunt), but it has done it with just browser and dun. The temp at the point of reboot is still only 31-32 deg c
As for the temp gauge, I did post to this group before. The Mobo cpu temp ,in the bios,is 50 deg c at turn on and all other times (Never changes). The System (ambient) varies with time, increasing from turn on. QDI's 'manage easy' reports the same.
MBM4.17 shows three sensors on the chipset, one stays at 50 at all times, another stays at 22 at all times, and the third varies, from about 24 at turn on to a max (so far) of 32. I am reasonably confident that the processor is not overheating, the HS is only just warm to the touch. I must assume that the temp labled 'system' is in fact the proc temp. (I hope)

can you up the voltage on the CPU ??


if not try a slower setting

[Graham]

Will check !, as usual, the mobo manual doesn't say (dont know why they bother with the bios descriptions !!)

Sorry for the late response. Your temps readings seem confusing. Anyway, watch out for the heat after you increase the voltage.

Oops just clicked submit too soon!!

Anyway, I don't have much to add. Upgrade all the relevant drivers and OS patches. Also, check your RAM if you could. That's all I can think of now.
Hope this helps.

No mention in manual or 'Speedeasy' setup of ways to change core voltage.

[skywalker[TSG]]

then try a lower CPU speed

my celerons @630 makes sudden reboots @645mhz but they work fine at 630mhz

i think this could be it

[Graham]

Yes, it seems 100% @ 744, just a shame I cant get 1 meg steps, or up the core volts.
Thanks to all for their help !!

Run the CPU at its normal speed and see if it will still reboot.
