At the moment I'm running in slow mode voltage 2.6. The memory is rated at cas 2 but running at cas 2.5 and is running at 2-3-3-8. So it running well under spec. It's possible that the board doesn't like running more than 2 modules as well. So when I get the replacement memory I'll just run two 512 sticks and see what happens as well.

Luckily I've got enougth stuff to swap around but investigations take time as my overnight run showed.

On my board 2-3-2 6 are about the only stable settings that would work at 400MHz (2x512MB Corsair XMS3500 C2). Even lower timings like 2-3-3 7, 2-3-3 8, 2.5-3-3 7, 2.5-3-3 8, 2.5-4-4 8 would give memtest errors and crash in Windows.
It's a long shot , but you could also try disabling PAT (turbo or whatever MSI named it), it might take down performance by around 5%, though it could make it more stable. You can use CPU-Z to check if it has been disabled (under Memory/Performance Mode).

Pats off as I'm in slow mode. I've got cpuz already matey.

I could also go back to Bios version 1.6 at later date. 1.8 wouldn't run at all 1.7 seemed okay.

Switched Computer on tonight and it promptly rebooted. Took one more memory stick out and it blue screened. Tried one stick and it blue screened but a different error.
So re-installing from last good image which rules out the cat 3.8's if this works properly.

[The PIT]

Well the old image wouldn't work either the machine rebooting within seconds. I then upped the cpu voltage and it's now running.
There does seem a lot of variance on the power rails. Sisandra says they okay. Msi software says they're a bit low but that doesn't agree quite with what the bios says. Something I'm going to have to watch. I'll stick my meter on it this weekend probably and see what that says.

which PSU do you have in use again?

[The PIT]

Antec Truepower 550. Should handle it.
Problem is software is crap at reading voltages etc. Three different bit's of software all different readings.

[dZeus]

550 ??? wow.. unless the PSU has gone bad, it should be MORE than enough for your system.

I'm currently using an 350 Watt Enermax with a P4 2.8C + 9700 Pro, and since I upgraded to Catalyst 3.8 I had no problem whatsoever yet (best drivers so far for me). Previous drivers gave me lots of 'infinite loops'.

[The PIT]

Try the 350 watt with 9800 pro I bet wouldn't work then. Mine didn't, different motherboard and processor by the way then.

The powersupply is driving six 80 mm case fans. One CD drive One DVD drive two hardrives, One plat ex soundcard, Rad 9800 pro, One usb hub One usb mouse. Scanner not attached at the moment.

Looking at the voltages theres around 0.5v swing according to the supplied monitoring software. Other software doesn't confirm this.

I can swap the power supply for another 550 Watt model I've got in another pc. My thoughts are either duff psu which I can swap. Duff Cpu which I can't test, Poor power regulation on the motherboard.

I left the machine running overnight with 3dmark 2001 and the programme dropped out sometime during the night. So I upped the voltage on the memory and cpu again. The cpu is at 1.6v and memory at 2.85. I ain't going any higher than that for the memory.

I wonder if the Audigy dieing took some other stuff out.

Actually, that 350W Enermax PSU might be up to the task, it can supply 26A on the +12V rail.
The 550W Antec PSU that we both have does 24A, makes you wonder.

I have an antec 550 as well, it is worth noting that all of the antecs rails are independent, whereas a couple on the enermax's are mixed. eg some rails will be derated as they "share".

Quite right.

[The PIT]

Well the 3d mark bombed out again. Looks like swap the power supplies.

The twelve volt line is going from 11.76v 11.54V The 5 volts is going from 5v to 4.89v The 3.3 line is 3.33 to 3.22 and Vcore is 1.63v to 1.58v. Doesn't look to smart to me.

[The PIT]

Well it looks like the Motherboard or cpu.

Can't check the cpu as I don't have another 800mhz compatable motherboard or know anyone thats got one. Neither do I have a another 800mhz CPU to try.

Swapped everything else out bar the motherboard and it just reboots all the time now. Video card, soundcard. No go.

Just ordered an Asus 800 E-Duluxe. Fingers crossed it's the motherboard still it's cheaper than buying a new cpu striaght off.

[dZeus]

sounds like bad voltage regulators on the mobo to me.

I've heard that the Asus P4C800-E is a great mobo. The only one I would consider getting other than the one I've got here atm (Intel D875PBZ)
