Problem with a7v8x

[Mensch_Machine]

Recently my friend purchased the A7v8x (Lan and raid) and decided to get a new cpu cooler. His choice was the Volcano 9. At the time he was running as follows:
A7v8x
Athlon 266 1.4
Unknown 350Watt power supply
WD 100 gig 7200RPM on the promise RAID controller
Mitsumi 1.44 floppy drive
HP 8x cd-r --------- on the primary IDE controller
Acer 16X DVD Rom ---
512megs of Crucial PC2700 in one stick
PNY GeForce4 MX 240
Sound Blaster Live X-Gamer
2 PC mods cold cathodes

The problem he ran into was that he... ahem... accidentially applied the new volcano to the processor with the protective paper still covering the adhesive on the Volcano.... and before post on the next boot he noticed a sweet burning smell and yanked the power. Ever since his board will not make it past the first beep of post before shutting itself off. We replaced the old processor with a new XP2000 and have the same problem. My first impression is that the origional processor burning up may have damaged the thermometer on the board and causes the C.O.P. to automatically shut off the entire system before POST. We're really perturbed by this one so any ideas on what may be causing this or what we can do about it would be appreciated. If it is the thermometer on the board it should be as easy as cutting a trace.

Speaking of sensors, has anyone noticed anything wrong with the A7V8X sensors.

I upgraded my system motherboard from A7V266E to A7V8X. My setup stayed the same other than motherboard. Suddenly my cpu temp drops from 48 C to 31 C. Mainboard temp was less dramatic: 35 C to 26 C. I hadn't updated my old board's bios in a while, though. My new board got updated immediately.

Also my Volcano 9 now frequently jumps to full speed (apparently 5500 RPM) even though my cpu temp has never gone above the lower 30s. Once it hits full speed, it will stay there til I shut the thing down and don't restart for at least an hour. It doesn't hurt the processor, though. The readings have fallen as low as 23 C. I never had the problem with the old board.

Setup(nothing is overclocked):
A7V8X
XP1900+
Thermaltake Volcano 9
512M PC2700(DDR333) OCSystem Ram
AIW 8500 DV
SoundBlaster Audigy Platinum
3com 905c-TXM
Aceex (Lucent chip) 56K modem
40gig Maxtor 7200RPM ATA133 HD
10gig Maxtor 7200RPM ATA133 HD
Pioneer 16x DVD-rom
Yamaha 44-24-44 CD-RW
Samusung floppy

I'll forgo the external components as they hold no bearing on the subject.

Remeber, they only thing that changed between this setup and my old setup is motherboard and bios revision.

Thanks

I guess nobody cares about the A7V8X now that the A7N8X is here. It must be a lot funner to complain about. I see complaints about the A7N8X everywhere, but I see next to none about the A7V8X. Makes it hard to troubleshoot.

If by chance someone has an A7V8X and can answer the questions above, would you spare the time to answer them.

I think that the one board is fried. It fried itself when the CPU burnt is my guess. It sounds like you have another working CPU that you put in & still nothing. I don't believe its any COP shutting it down.

The lower temps with the A7V8X are because of a BIOS update. If you look at BIOS 1010 it was solely to calibrate the ASUS temp.'s on the MOBO. I was running the board prior to the BIOS update. I was running 45c idle & 48c under load. After the BIOS update my temp.'s dropped 10c on all readings. Did the temp.'s change on the MOBO, no. They just made it say what they wanted it to. That's all there is to that.

The reason you don't hear much about the A7V8X is because everybody & his brother are building A7N8X's. They are the fastest & people are pushing them the hardest. They are a super fine board & are completely stable. It's the people pushing them for all there worth that are having some problems at this point. Or they're using substandrd / old parts. After all the A7V8X only had a short rein as the fastest chip & then the A7N8X came out & that's about the size of it. If I hadn't built in Nov. last year, I'd have a Nforce board myself right now.

If it ain't broke, take it apart & see why not!
