Random reboots (every once in a while)

[endorphin]

This doesn't happen too often, like 1-2 times a week, still it stops me from having a 100% stable system, which pisses me off.

The entry in the system log looks like this:
Event type - Information
Event source - Save Dump
Event-ID - 1001

Datorn har startats om efter felsökningen. Felsökningen var: 0x0000001e (0xc0000005, 0xa00c222a, 0x00000000, 0x00000048). Microsoft Windows 2000 [v15.2195]. Innehållet dumpades och sparades i: C:\WINNT\Minidump\Mini061403-01.dmp.

Im running a Swedish OS so yea thats in Swedish

So heres a translation:
The computer has rebooted from a bugcheck. The bugcheck was: 0x0000001e (0xc0000005, 0xa00c222a, 0x00000000, 0x00000048). Microsoft Windows 2000 [v15.2195]. Copy of memory was saved: C:\WINNT\Minidump\Mini061403-01.dmp.

As I said, the reboots are pretty random, I haven't really found anything that seems to be the problem.

The only info I found was this:
0xc0000005 = STATUS_ACCESS_VIOLATION - A memory access violation occurred. (Parameter 4 of the bug check is the address, which the driver attempted to access.) Typically generated by faulty drivers.

Which doesn't tell me alot.

My setup:
EPoX 8RDA+
2400+ @ 2100 (168x12,5)
2x256mb pc3200 not sure what brand
Geforce 3 Ti200
1xSeagate 120gb (Ive had some problem with this, corrupt files etc)
1x180gb 180GXP

Running Win2k with service pack 3

Any ideas appreciated

Add some voltage to the memory and retest, if it still happens, change memory timings to 7-3-3 @ cas 2.5 with added memory voltage and retest.

What voltage are you running on the cpu. Some 8rda's (usually rev 1.0) have been shutting down due to the over voltage protection kicking in. Generally only above 1.85v.

[endorphin]

Im running all voltages standard
Maybe that's a bad idea, Im a newbie at overclocking and havent got to the voltage bit yet =)
What voltage should i try on the RAM, and what should I use to test it (since right now It really doesn't reboot that much under normal use)

Do you have a raid controller on mainboard?
I have the same problem with my 4G4A+ after a Bios update.
When I updated mb BIOS , I update too HPT BIOS...

[endorphin]

Nope, no RAID
btw, is there any number that devices have except for IRQ? I got the idea that 0x00000048 meant device #48 was the problem. I have no idea if this is correct but I thought Id check

Try upping the cpu voltage by one notch as you are overclocking the cpu by 100mhz and see if this results in more stability.

Get hold of prime95 and run the torture test to see if cpu and memory combination is stable.

Lower multiplier so cpu is definitely not limiting factor and raise fsb slowly and test with prime. When instablity sets in raise mem voltage one notch and retest....... until find out max speed of memory.

Then repeat to find cpu max speed changing fsb and multi.

When o/cing only change one seting at a time otherwise if instability sets in you won't know what has caused it.

Takes time but is worth it for 100% stable system.

Keep an eye on the temps. Don't want over 50 degrees c under load on cpu really.

I think you may be barking up the wrong tree, theres a difference between OVP that shuts the system dead and a BOSD that involves a save dump.

I'm having these save dumps sometimes...for me I suspect the PSU since I've modded the GFX card and it now draws more V's, but there again I've just ran 8 days on the trot without a reboot.

endorphin,

If you are running all stock voltages for your OC then it would explain the random reboots.

Try upping Vcore and Vdimm a notch and keep everything else the same for the time being. Do as thewoZa advises and get prime95 and try and get that to run at least 4 hours without failure.

If your CPU can do this try running a few loops of 3dmark01se, if it passes this then you know you have a more or less stable setup that maybe only needs a few tweaks for performance.

My rule of thumb is prime for at least 12 hours and it also passes a few loops of 3dmark for a system to be stable.

HTH.

Endorphin, please check the 5v line of the PSU, I had the same kind of reboots, and my 5v line was at 4,7~4,8v (8k3a with xp1700 @xp2000 --> 166x10 @ 1,5v).
I've changed the PSU to a 350w PSU, and the problem dissapear.
Now, my 5v line is 5,02v in USDM application.
