1 out of 5 eggsLooks good, but bad quality and support

Pros: When I first spotted this MB it looked flawless to me
2 PCIe x16 ports, 1 PCIe x4 but the slot itself is x16 size
Onboard video
Display port + HDMI + D-Sub + DVI
Tons of USB ports

Bonus:
2 x Gigabit ethernet port

Cons: DOES NOT OVERCLOCK Phenom II x6 1090T CPU. When I try to manually set any multiplier or voltage in BIOS the CPU goes to 800MHz and does not move from there.
No IDE port. For some it may not be a con, but I had my DVD-RW on IDE cable to free up some SATA for HDDs
My first motherboard had its onboard video broken I've spent more than a day trying to figure out what's happening, almost everything looked OK, but when I tried to play hardware accelerated video it just hung. ECS replaced the motherboard, but I still had to pay for shipping.

Other Thoughts: Will never buy from ECS again, this was my first and last try. Just look at their website, it's disgusting and support is nowhere near acceptable.
It seems that they have good and inovative ideas that get implemented into a bad product.

4 out of 5 eggsIssue with displayport

Pros: Seems pretty good for the most part. No major glaring problems that can't be dealt with, dual digital outputs can be activated simultaneously.

Cons: The manufacturer messed up the DisplayPort circuit.

The AMD 890GX/RadeonHD4290 supports DP++, which means that it is capable of driving DVI or HDMI single link display devices on the DP port. The Cable Adapter Detect line is apparently NOT CONNECTED, which means that it can't detect that a DVI or HDMI adapter is present on the DP port, instead, the vbios (v is for video) is hardcoded to DisplayPort and it is stuck there for the most part.

The display detection and initialization sequence is such that the DRIVER and VBIOS have ultimate control over the way that the DisplayPort outputs are configured. In this case, the DRIVER reads the connected display type from the VBIOS and sets the output to DisplayPort.

Other Thoughts: With an operating system that uses OPEN SOURCE DRIVERS, it is possible to OVERRIDE this and force the outputs into TMDS/DVI mode.

The following patch for the LINUX KERNEL can be used to activate TMDS/DVI:

--- a/drivers/gpu/drm/radeon/radeon_connectors.c
+++ b/drivers/gpu/drm/radeon/radeon_connectors.c
@@ -998,6 +998,9 @@ static enum drm_connector_status radeon_dp_detect(struct drm_connector *connecto
}
}

+ radeon_dig_connector->dp_sink_type = CONNECTOR_OBJECT_ID_DUAL_LINK_DVI_D;
+ ret = connector_status_connected;
+
return ret;
}

Notes:
1) This will ONLY work with open source drivers, which means that if you like MSWIN operating system, you can't do this.
2) This is a HACK -- and it BREAKS actual DisplayPort.
3) It IS POSSIBLE to add a BIOS option to force it into TMDS/DVI mode. ECS: This is directed at you!

5 out of 5 eggs890GX with simultaneous DVI+HDMI

Pros: same

Cons: same

Other Thoughts: @N/A: the DVI not working at the same time as the HDMI is not a chipset limitation, it is a BOARD limitation. In exactly the same way as you can do DISPLAYPORT+DVI or DISPLAYPORT+HDMI, you could simply replace the physical plug of the displayport with either a DVI or an HDMI. Remember that these things are all more or less the same thing.... DVI is a subset of HDMI, HDMI is a subset of displayport (at least in the case of radeon chips...). The fact that THIS board can do displayport+HDMI means that on this same chipset, there is no problem at all in providing ANY pair-combination of DVI and HDMI and having two of them working at the same time.

5 out of 5 eggsDual digital display

Pros: Dual digital display support -- 1x (dvi or hdmi), 1x (displayport+dvi/hdmi adapter). This is literally the ONLY 8xx board out there that can take two digital displays on the onboard graphics. Note: that does NOT mean that it will take one on the dvi and one on the hdmi since they are wired in to the same place like every other board out there. The display port disables the first x16 slot, but that is because the 890gx only has so many PCIe lanes available.

Cons: More SATA would be nice... 8+, and it is shameful to waste an SATA on being external-only. Also would be nice if carried the A890GXM-A2, which has USB3 (the -AU comes with a USB3 add-in card, but IMO too messy, better onboard).

Other Thoughts: In transit.... going to mix it with a 1090T and 4GB (2x2) of OCZ 1600 MHz 7-7-7-24.

The reason for most boards having two of the same digital display outputs is that they're CHEAPING OUT. The second digital output is PCIEPHY, which uses PCIe lanes, which either take away a slot (which looks bad in advertising), or requires extra work to implement a toggle. SHAME ON ALL OF THEM!

1 out of 5 eggsGraphics issues continue

Pros: Comes with SATA Cables.

Cons: Follow-up on Graphics issues. You must have an old VGA Monitor available to even see the BIOS and set the BIOS to default. This allows you to see the DVI and HDMI signals.

Problem: After Installing Windows 7 Premium Home the HDMI Monitor says "Generic PnP VGA Monitor". Tech Support had me install the MB Drivers. WOW! The HDMI AND DVI Signals disappeared completely. All I had was a Generic VGA Signal on the VGA Port. After trying to set-up the HDMI and DVI individually and then together I called tech support again. They said I can not use both Digital ports, HDMI and DVI, at the same time for dual monitor usage. But, they should be working if only one is connected. Wish that had been revealed by all of the reviewers out there. Such high marks for such a problamatic MB is not understandable.

Other Thoughts: Bottom line. I was thoroughly disappointed with this highly rated MB. I will be seeking to return it for a refund and probably buy another ASUS for a replacement.

Manufacturer Response:

We sincerely apologize for any miscommunication that you may have encountered.

This is true that "DVI and HDMI share the same signal so they cannot be used at the same time."

For your reference this is listed in your user’s manual on page 15, along with a graphics output matrix.

3 out of 5 eggsECS Follow-up

Pros: The MB received a lot of praise from the reviewers.

Cons: The DVI output was dead.

Other Thoughts: This is in answer to ECS's response. They seem to be stuck on saying I have a problem with the HDMI. Hmmmmm. Could that mean I should expect a problem with the HDMI?

My problem was with a dead DVI output. Which, they failed to address in the response posted here and on my original support ticket. QUOTE: The DVI Port on my board is dead. UNQUOTE:

Manufacturer Response:

We sincerely apologize for any miscommunication that you may have encountered.

There are no known issues with DVI.

You should not expect any issues with HDMI either.

If you continue to have issues with your replacement motherboard, please do contact us and we will help to either resolve your issue or help ensure you have a good motherboard.

3 out of 5 eggsA couple of issues

Pros: A lot of good features for anyone who just wants a solid home system.

Cons: The DVI Port on my board is dead. ECS has not responded to a request for support. So, I am RMAing this board for a replacement. Hopefully the replacement will work as advertised. The BIOS screens are not even close to the ones shown by the different reviewers and ECS. I have seen four different versions of the same screens. Yet, they are all classified as V 1.0. How can the set-up screens be so different between systems, if they are the same version?

Other Thoughts: It does not allow for OverClocking. And, the lack of accurate documentation for the BIOS Set-up is a little wierd. It kept giving me a Memory Checksum error and yet reported the Memory installed.

Manufacturer Response:

We are sorry to here about your HDMI not working.

If you still have this motherboard in your possession we would like to look into your issue and find any possible solution.

We would like to find out how you contacted us and look into to your previous case to address any concerns with support.

You can find the over clocking features in the M.I.B. III section of your BIOS. If you need help with the options please contact us.

4 out of 5 eggsVery interesting

Pros: Price considering the features available. I am mostly wondering about unlocking. My understanding is that the new southbridge will not unlock cores unless the mobo manufacturer provides for this in hardware. The description doesn't say anything about this...
If my understanding of the new chipset is flawed, I would like to know as I have seen lesser 890gx boards with reviewers' claims of unlocking. The 890gx is supposed to have acc disabled.

Cons: The northbridge HS is robust but the SB looks like a thin aluminum weakness that I've seen in about a hundred motherboards. Sometimes this is not a pb, and sometimes you will have soaring system temps.

I have no problem adding a chipset cooler, in fact you can get subambient temps that way but unfortunately this would block a crossfire config. Thats the pb with my biostar 790gx, I had to add a chipset cooler (system temp=80C!) and now I can't crossfire.

Oh well, my system rocks anyway. :)

Other Thoughts: Eventually I'd like to get one o these, but I would have to change my AM2+ CPU and ddr2 ram. Prolly wait a little while and save up, maybe get a nice hexacore.

Hope some folks give this one a try and post some informative reviews.
