Rampage IV Extreme 00 Code After Shut Down

Yes as Raja mentioned the worser cause may be the monitor leaking into the VGA into the MB. So try as he said OR try diff monitors.
As for P6T being ok, theres no irog IC working on the P6T while on R4E there is and this leakage may cause it to go a bit bonkers.

I do not have extra displayport cables. I will try to locate some. In my opinion it is not the cables for the following reasons.

All three cables or all three monitors must be bad because I was able to duplicate this issue with different variations of cables and monitors.

I also duplicated this issue connecting two displayport cables and one DVI cable and two DVI cables and one displayport cable.

Same reasoning for ASUS monitors - it is either the systemic flaw with all VE278Qs or something else.

A workaround of powering of monitors during post does not work. ASUS monitors do not support hot-plugging of displayports. Doing so results in blank screen.

Are you guys will still try to duplicate this in a lab? Thanks.

If the DP is resulting in DC leaking back into the board some devices will receive power before they are supposed to be initialized. The end result is that this screws with how the board POSTs.

The only fix is to prevent the the DC, so there is no real fix I can think of to your situation at this point I'm afraid. Only other option would be to find a monitor with no DC present on DP, but I don't even sure that is possible (have not looked at full DP tolerance spec myself) given the fact that the transceivers need to be at standby to accept a wake up signal. I am not sure if other GPUs leak power like this back into the board from DP either.

we have tried already to no avail, we will try to make 'monitors' leak and see what happens. for the AC cables for your monitors do they have the earth pins on them or just live and neutral pins?

Shamino,

All three monitors use three pin grounded AC cords.

Raja,

I am trying to understand the impact of your last statement.

Are you saying that possibly Rampage IV does not support ATI Eyefinity configuration with HD 6990 and maybe other ATI GPUs over displayport connections with ASUS VE278Q monitors?

That would be quite a severe limitation...

Thanks.

Can't be certain as you are the only person I know of with such an issue thus far. And if HQ can't replicate it, who knows where the fault lies.

my secondary school has them the same problem and it has disassemble this WaterBlock then take back up Waterblock and code 00 one gtx590 therefore disappeared on if she can to help her comes of too tight waterblock!!!!

Thanks athos67, but I'm afraid this was already suspected and tried. The waterblocks were re-seated and are not tight. My issues have very specific circumstances.

Just to be clear:

Here are the steps I just tested:

1 PC is running @ 4.5Ghz / Eyefinity w/3 monitors via 3 DPs
2 execute windows shutdown
3 bios button does not work
4 remove one DP
5 bios button does not work
6 remove second DP
7 bios button now works!
8 unplug both PSUs
9 connect one of monitors via DVI
10 power both PSUs
11 bios button still works!
12 boot up @ 4.5 GHz
13 no code 00
14 execute windows shutdown
15 bios button still works!
16 repeat steps 12 - 15 - no issues!
17 execute windows shutdown
18 remove DVI
19 bios button still works!
20 plug in second DP and boot up
21 no code 00
22 execute windows shutdown
23 bios button does not work
24 plug in third DP and boot up
25 code 00
26 unplug and power drain
27 boot up
28 code 00
29 unplug and power drain
30 boot up
31 OC failed message
32 F1 and F10 save
33 boot up @ 4.5 GHz / 3 monitors via dp
34

please let me know exact model of display port cable you have!
pinxx of Cable should be floating and not connected BUT some nameless companies made cables with them connected at both Ends!
