Ongoing … Asus suggested either defective displayport cables or defective Asus VE278Q monitors

Asus suggested it is a DC voltage issue caused by either defective cables or defective Asus VE278Q monitors.

I respectfully disagree:

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 Asus VE278Qs or something else.

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

I am still hoping that Asus will still try to duplicate this in their lab…

Testing continued…

Removing monitor power during post does not resolve issues.

If I execute Windows soft shut down and prior to post remove the power (unplug ac) form either all or any two of three monitors then I can post and switch BIOS. It also works when I unplug any two or all display ports.

Just softly shutting down my system without unplugging or removing monitors/displayports results in the code 00 and the inability to switch BIOS issues.

I’ve also tried mixing connection types (i.e. one DVI / two display ports and two DVI / one display port) resulting in exactly the same issues.

Enabling “wake on” options in BIOS did not resolve these issues.

My monitors are ASUS VE278Q.

Same Eyefinity setup functioned perfectly with my prior Asus ASUS P6T DELUXE V2 motherboard.

What are next steps? Will it be communicated to Asus engineers?

More testing….

Root cause found, but not solution

I have two crossfired HD 6990s video cards and with three ASUS VE278Q monitors setup in Eyefinity configuration. The monitors are connected to video cards using three display port cables.

The monitors, video cards, and cable are all proven items from my prior build.

I have three following issues:

I cannot switch to the second BIOS via the BIOS button – this happens even on default BIOS settings.

Randomly disappearing USB 3.0 controllers – this happens even on default BIOS settings.

Code 00 cold boot problem if any CPU related performance options (clock, blck, etc) are set to any values other than defaults. As I had stated previously anything besides turbo=auto does not work regardless of memory settings or turbo ratio settings.

 

Root cause:

Disconnecting two of three display port cables resolves all three problems.

It does not matter which of the two cables I disconnect or which of the two video cards I use. I have tried every permutation of video cards, crossfire settings, cables, and monitors with exact same results.

I still think it is somehow related to the chipset, motherboard, or the BIOS. Bizarre issue…

RMA Hell… Next Suspect – CPU

Asus support and community has been very responsive.

Last night I installed the new Rampage IV Extreme motherboard number three. The install went very smooth, sadly except for results. The first post was flawless and the device manager was showing four Asmedia controllers. This is with all stock BIOS settings apart from the SATA RAID. I booted into BIOS and set BCLK = 101.

Everything booted without any issues. After performing a shutdown from windows, waiting 60 seconds and pressing the start button on the motherboard the post got stuck with code=62. After waiting for few minutes I unplugged the power, reset the BIOS, restarted, and booted into windows without any issues.

Another soft shutdown resulted in the same code=00 post. I reset the bios to defaults and rebooted without issues. The devices are only showing 3 Asmedia controllers and two of the back ports are not detected.

With this motherboard even with the default BIOS settings the PC consistently results in code=00 after a windows shutdown (with power connected). Code 00 is cleared by disconnecting power for 30 seconds and rebooting. Once booted PC is 100% up to 4.5MHz.

Bluetooth is working OK.

The BIOS button is not working. When the BIOS button is pressed LED 1 remains lit.

I am officially stumped.

At this point I have to agree with Asus engineer Shamino and the support staff that CPU is the next suspect.

In summary:

Consistent code 00 after a warm shutdown.

1 Asmedia controller is not recognized in windows 7 Ultra.

BIOS button does not work.

 

New Enermax Platimax Dual Power Suppplies

While waiting for RMA for my second Rampage IV Extreme motherboard I upgraded to a dual Enermax Patimax PSU setup.

ENERMAX Platimax EPM1200EWT 1200W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS PLATINUM Certified Modular Power Supply

ENERMAX Platimax EPM850EWT 850W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS PLATINUM Certified Modular Power Supply

More Issues

So far the RMA board is worse than the first.

List of issues:

Cold boot code 00 bug (same as the previous board)

http://roadczar.com/th10/?p=271

One of USB 3.0 controllers is not working (same as the previous board)

http://roadczar.com/th10/?p=297

Second BIOS will not boot. Also cannot switch to the second BIOS using the BIOS button on the motherboard. This is a new bug that was not found on the first board.

What’s next RMA or refund?
