*Official* Gigabyte GA-E7AUM-DS2H Thread (NVIDIA 9400 mATX HDMI 8 channel LPCM) - Page 14

Are you using F12 to select the boot device? If so, are you scrolling down past "CD/DVD-ROM" all the way to the end where you'll see a longer string describing your particular DVD-ROM? That's the SATA/ACHI one - if you're selecting CD/DVD-ROM from higher up in the list, that won't work.

I just connected the HTPC with a D-SUB and a DVI monitor, all works fine, clone mode and other stuff was able to select.
But as soon as I feed the second monitor with HDMI instead of DVI to following happens:
Vista sees the monitor and shows me its name, I can edit things like resolution and stuff in the nvidia settings control center. It even shows me the HDMI cable connection where I can switch between the 420p, 720p, 1080i and 1080p resolutions.
But the screen stays black...

I really don't know what to do and I'm only about a inch away from kicking the whole HTPC out of the window. The computer sees the monitor but sends no signal, why?
And how to fix that?

Or did I really get a second MB that is broken in a way?

I have the same problem with my hdtv and certain resolutions over hdmi. some of the resolutions work for me if i select the correct refresh rate. try a bunch of different combos and see which one works. my guess is, that it isn't the motherboard, but the drivers for the 9400. see my earlier posts in this thread.

currently i have 3 fans in my system. a single 120 plugged into the cpu fan header with it's speed regulated by voltage in the bios. an 80 plugged into the system fan header speed regulated by voltage in the bios. and an 80 plugged into a molex (running at full speed all the time...).

my question is, is there a way to voltage regulate that 3rd fan automatically like the bios does with the other connected to the fan headers? speedfan shows that there are some how 3 fan headers, but the bois and the board only show 2 headers.

is there a way to tie the two 80mm fans into the same header and have that regulate them both? if so, will this cut the voltage supplied to them in half, and thus the speed?

any suggestions for a solution are much appreciated. thanks!

kevinkreiser, or anyone. So does the 9400 not support 1360x768. I was planning on using the 9400 in a new htpc, but probably will look to alternatives if 9400 does not support 1360x768.

I was not able to get this board to work over HDMI with my Yamaha receiver. My old G45 based board did work the receiver. It wasn't a problem with the this board's HDMI because that worked just fine with my Westinghouse monitor HDMI input. I'm guessing this is some sort of HDCP problem. Like you, everything looked like it should be working but I only got a black screen. When I was playing around, I noticed that I could get the audio over the DVI. That was a surprise to me. I thought that only HDMI carried the audio. In the end I opted to run the video directly to my TV via DVI and the audio over the optical SPDI/F to the receiver. Since I only use 5.1 surround sound this worked just fine for me.

I wonder, has anyone tried a DVI to HDMI adapter to see if that would work for both video and sound? If I ever pull the thing out of the entertainment stand I'll check it out myself.

3-pin Y cable or "Daisy-chain"? (Check this post.) Voltage is not cut in half in parallel connection.

I have a stupid question. I'm looking into building an HTPC with this motherboard and have noticed that alot of people recommend a video card. Why? If the motherboard has onboard HDMI, then why do you use a video card that has DVI out? I'm just failing to wrap my head around this concept. Thanks.

Well that's just frickin great. Anyone using this board strictly with HDMI to a Denon 4308? Now I'm worried.

They want better 3D performance for gameing and like the features of the motherboard. Depending on the card used, they could also be using Hybrid SLI for performance gains as it uses the onboard HDMI connector.

I can NOT get it to work at 1360x768 over HDMI with my HDTV. Over DVI it works at that resolution with my monitor, but since my HDTV doesn't support DVI I can't tell you whether or not it works with the tv. At any rate, I don't think this is a hardware limitation. Rather I would bet it is a problem with drivers. Honestly I dont know though.

My solution is to set my HDTV resolution to 1280x720@60hz over the HDMI cable. This solution works but creates overscan. So then you have to use the nvidia control panel to "resize hdtv desktop". The only problem then, is that every time you turn off the tv or reboot the settings are lost and you have to do the procedure again.

You'd be better off with another card that supports HDMI and is known to work. The you can use the DVI connector from the motherboard for your monitor, and use the other card's HDMI for your tv. I have no idea what hards have good HDMI capabilities though (specifically with respect to audio).

Wow, this is very disappointing, and hard to believe. I have a 2 year old Nvidia card (can't remember the exact model off the top of my head) that supports 1360x768. Why would the 9400, which is targeted towards the htpc market not support the native resolution of many hdtvs, including my own?

I hope a driver update will address this soon??

that's great, thanks a lot. by the looks of it, there is no special hardware (resistors etc.), just wires. i think i'll just splice some together rather than wait/pay for shipping. thanks!

i also find it hard to believe, that's why i've asked other people to validate it. it might be a problem with my specific tv or my specific motherboard. i have no idea. if anyone else has it running over HDMI at that resolution they should speak up!

Does your HDMI input accept PC signals? 1360x768 is not a HD resolution. Maybe you have to set something in your user menu of TV for native resolution. I had it working on my 26" Regza when setting up the board but it accepts PC signals over HDMI.

I am going to build one of these up for a HTPC next week. My buddy is looking at it for a lowend gamer as well. He plays 360, and I play TF2, L4d and what not on PC so he want in on the online gaming too. I just happen to have a pair of 8500's collecting dust (thanks to my GTX260 replacements!) so I was going to throw one his way to hybridSLI them.

My question is what game(s) did you use to benchmark your rig? What were the settings and how was your FPS? I saw on the ndivia hybridSLI demo video COD4 played 20fps out of the box and around 40fps with the sli going. but who knows the settings and res.

Just tried some resolutions, just HDMI to my full HD tv, and 1360x768 is no problem......

good to hear! it must be a problem with my tv then. using vga the tv works perfect at 1360x768 though so this is very confusing. i'll have to try another tv.

it doesn't mention that it "accepts pc signals" anywhere in the manual or anywhere else for that matter. all it says is:

HDCP compliant
E-EDID compliant
Supported scan rates: 1080i, 720p, 480p, 480i

That's about it... Maybe my tv is junk, it was pretty cheap.

Edit:
It also has an audio input (stereo) that says "PC IN AUDIO". I guess it's for when you use VGA and no audio is being sent otherwise. And the remote control has a button to select a PC input, which switches between HDMI and VGA.

You might be able to make a custom resolution in Nvidia control panel for 1360x768. I wouldn't say junk, you like it don't you, maybe not full featured.

you do have a DVI IN at your TV? Because beamers don't habe DVI IN...
That's my problem...

Could it be that You HDMI cabel is too long? do you have any other HDMI devices to test?

But are you able to see the BIOS anyway?
I don't see anything but it is recognized by Vista in the control center. That's the bad thing...
I'll try other resolutions and refreshrates but I don't think........

yes i do see the bios screen. well i see it post and then wait to boot ahci cdrom. the resolution is probably 800x600 though and I am sure that it isn't 1360x768 during post.

i like it in all regards except that it won't work correctly with my htpc (as i would like it to, or as i think it is intended to). i tried using the custom resolution thing and it doesn't work either; although i didn't try to mess with the advanced settings. so anyway i'm going to take a picture of it and post it here when i get a chance to show exactly whats going on with it.

my methodology is this. I'll draw a single pixel wide black line horizontally, and another single pixel black line vertically, both on a white back ground. if the tv is at the correct resolution, these should both be only 1 pixel wide on the tv. if there is any scaling taking place then they should look blurred in either the horizonal (horizontal scaling) or vertical (vertical scaling), or both directions. of course the tv implements some crappy deconvolution algorithm which just adds ringing artifacts around everything.

basically i want a tv that can accept input from the computer and replicate it pixel for pixel. no overscan, no bluring, no sharpening. it's probably too much to ask.

My HDMI cables are 2 and 4 meters long.
And yes, I tried it with both my beamer and a HDMI compatible Monitor from benQ.
The really only things I haven't changed are the CPU, CPU Cooler, Power Supply and RAM. Everything else has been changed including the board itself and that's what is so confusing about the whole case. Probably a third board will make the HDMI work...
I could change the CPU, the Power Supply and the RAM just to make sure that they are not the bad parts.

I have disconnected the HDD and LG BluRay drive because as long as I do not see the BIOS/startup screen I won't see anything in Vista, therefore I don't need the HDD for the tests...

I normally don't "do" games... but my son wants me to put a flight simulator of some sort on it...

Guys,
I'm about to finish my first PC build using this mobo. I have a question that might sound dumb and obvious to you all but:

my plan is to install vista 32 premium with AHCI enabled in bios. from what I gather, this shouldn't be a problem with Vista. My question is, will vista recognize this and install/enable the MS AHCI driver automatically? Do I need to install the Gigabyte driver right after the vista install? during? if during, how's that done? Should I just load it in IDE mode then install/enable the AHCI driver, change bios, reboot?

Thanks in advance for any advice

AHCI driver is included in Vista. So you can install Vista in either AHCI or IDE mode. If you installed OS in IDE mode, then you can switch to the AHCI mode later easily by enabling the AHCI driver (read this article ) and select AHCI in BIOS.

Forgive me if this has been asked before, but a search didn't really turn up much.

I'm about to embark on my first HTPC build (veteran system builder though) and I've planned on using this board for my build. I'll be running XBMC as my main "front end". My purpose is to replace the trust old XBOX with a high def capable system. It seems that the current recommendation is for a C2D e8400 or higher to be able to handle any 1080p content.

What I'm wondering though, is how good of an overclocker is this board? My current desktop setup was my first overclocking experience, q6600, and it went great. From what I hear the e7300 and e5200 are great overclockers with the same cores as the e8400, just lower cache. I could save a good bit of money by picking up one of the "lower end" processors and just OCing to 3Ghz.

Any thoughts?

Thanks in advance,

David
