Weird instability problems

[Henry Rollins II]

Running Cel700@875 1,8 volts, AGP/CPU 1/1, W98. System environment temp 37-39 degrees Celcius.

Problems are:
*Spontaneous restarts
*Games terminate themselves(SC, CS)
*B.S.O.D. with all kinds of messages

In addition to this, loads of new problems occur since I changed the CPU(prev. Cel 300A@454):
*D: harddrive seems to be defective(speed variations). Old IDE from 1996.
*Graphics cards seems to be defective, fps is about 0.6 in 3Dwinbench2000. Cannot complete all tests without system mess up. Graphics errors during gameplay.

All this come without any kind of warning; I may work with the computer for hours and then BANG!, goofy.

What may be causing those weird problems? Could this be due to CPU instability only? Is boosting voltage the medicine? How far can I go without burning the CPU?

regards,
Henry.

In my experience, overclocked coppermines get crazy around 38c, 37c is max for my 600E PIII (cBO), my 700e(cCO) seems to run a little cooler.
1.9v is the max I would try, but some have gone as far as 2.0v with success, but you should make sure you have really good cooling. For these speeds, an Alpha or globalwin or watercooling is a must have item.
In most cases, stability is achieved when the cpu temps are droped even by a little.
I was thinking...do you have clean power to your comp? by clean I mean no other apliances running on the same circuit.
Also is your power supply up to the job? could be when you get a surge, your power supply might have to work harder to provide adequate current.
I hope some of this helps

you may try boosting the voltage, but chances are that the sys files are already corrupt. I've heard of several systems "all the sudden" not being able to maintain their normally stable system speeds. Since it's summer, have your temps increased as most of ours have?

Clock it back just a bit and see if it helps.......however if things are already corrupt, sounds like a reinstall is in order. =(

I´ve tried clocking it back....but the problems seem to somewhat the same, even though they don´t appear to be fully that bad. Summer temperatures around here seldom exceeds 25 degrees celcius, so that is propably not such a big problem. :( (Wintertime we have down to -15 around here, maybe the perfect cooling solution during winter would be just to place the computer on the balcony?!? :D )

I think the PSU is a 230W. My entire apartment has only two fuses(+wash/stove), so letting the CPU having it´s own circuit is no option.

I´m seriously thinking about putting back the 300A in this system, and use it for CD-burning and scanning purpouses only. Since I already ordered new memory(256 Mb cas2), new harddrives(2 x samsung 30,7 Gb), new graphic card(MX 400 64 Mb), I might as well buy a new case and MB too. And maybe some water cooling too!

Why would you put back your 300A@454 in? You might as well keep your 700 not overclocked. And i think that your computer is crashing because the cpu is overclocked too much, i also think that the 83MHz agp is unstable.

I know this will be unpopular, but I would never do an upgrade like that without re-format and re-install. By starting clean, you avoid soooo many oddball B.S. problems :)

Abit home page):
Do the BH6 Rev. 1.00, 1.01, 1.02, 1.03, etc. and up (BUT NOT 1.1 and above) boards and the BX6 Rev 1.00, 1.01, 1.02, etc. (BUT NOT BX6 Rev 2.0) boards support Coppermine CPUs?
No, the BH6 Rev. 1.00, 1.01, 1.02, 1.03, etc. and up (BUT NOT 1.1 and above) boards and the BX6 Rev 1.00, 1.01, 1.02, etc. (BUT NOT BX6 Rev 2.0) do not support Coppermine CPUs due to the native design of power for the CPU core voltage probably not being sufficient. So to avoid instability, we advise that the afore mentioned boards do not support Coppermine CPUs.

Got an email about this....is it correct? Could this be the cause to my instability problems(or a part of it)?
