Besides I've noticed people have had issues with that board, I like to help out and since I got the Asus working, I'll give my shot at the ECS.

Friday guys, Friday...

Cool. My parts will be here over the next two days. Hopefully I'll have time to tinker this weekend.

Where is your belief coming from? Any source?

Well, audio without video is not really worth it (when talking about a movie). I think he means HD audio with HD video at the same time.

I found this slide from nVidia:



It shows the 8200 will only be µATX and makes no mention of the 8300. It is from CES.

But I did find this:

On the audio side, the HDMI interface offers support for 8-channel LPCM, provided you install the necessary NVIDIA driver set. Our driver support disks had this driver installation tucked away from the normal chipset installation, so be sure to load it if you want multi-channel LPCM. This feature matches Intel’s G35 chipset and is a far better alternative to the AMD 780G that sports 2-channel LPCM for the HTPC audience.

The Rest of the Family
Remove the nForce 200 chipset and what we have left is the nForce 750a SLI product. In our initial testing, we have not noticed any measurable differences in performance between the two chipsets.

http://www.anandtech.com/printarticle.aspx?i=3305

Basically, the 8300 (I assume it just did not make it to the slide) should not have anything which will improve the audio issue the 8200 is having. Both are µATX boards only (or at least nVidia intended them to be).


EDIT: I found out the 8300 is the MCP78U and the 8200 is the nForce 730a

I also found this:

GeForce 8300 is a upgrade version of GeForce 8200, have a higher Shader clock(up to 1500MHz), and better GeForce Boost performance.

I see. Video+7.1 ch audio in theory. Then he is partly right. Corrected.

ahh the confusing an f**ked up world of NVidia chipsets...

I have a 680i MOBO with two 8600 GTs SLI'ed, have done a ton of research, am generally good at this stuff, yet I still had to RMA a card, bought worthless "SLI memory" etc.

What I have learned though is that the chipset itself is the important part, but NVidia is purposely vague on its features in order for the makers to "brand" their version in supposed enhancements. In addition, am I correct that the "Purevideo Hd" in these new chipsets is still v2: with some control enhancements but with the same base engine? In addition, all of the 3D enhancements(and settings!) have little bearing on video processing?

As far as "full" PCM audio over HDMI - one of my 8600's actually *has* an HDMI out. However, the audio is simply a bridge to the MOBO RealTek audio processor. It is pretty neat that they are beyond this state at least.

No no, the new GeForce 8200 IGP actually has it's own audio controller inside that is correctly setup to do 8-channel audio over HDMI. No audio bridge/connector.

I coulda gone the rest of the day without seeing this. Now back to square one. So simply put:

Code:
                        nVidia Mobo

   mGPU         Form Factor     Hybrid SLI      GeForce Boost
----------      ----------      ----------      -------------
GeForce 8200       µATX           Yes              Yes
GeForce 8200       ATX            Yes              Yes
GeForce 8300       ATX            Yes              Yes
nForce 730a        ATX            No               Yes
nForce 750a SLI    ATX            Yes              Yes
nForce 780a SLI    ATX            Yes              Yes
And the better boards are generally at the bottom, with the exception of the nForce 730a board (a full ATX form factor version of the 8200)?

Is there anything else?!

I think we should have a FAQ and status update in the first post.

Then people don't have to wonder what chipset is what, the differences between these boards and all (except for g35 intel boards) other hdmi ports, and which boards people have gotten working with what driver sets and operating systems.

we can also list the currently available and future boards, and which software players are working.

i think all this information is already in the thread, it just needs to be compiled.

renethx already has a bunch of good info in the first post, but I think adding user experiences would be valuable.

Agreed. There is a short list of user experiences here.

Does it work? Sure.

Is it acceptable? Never.

Would anyone accept a BD player that had two HDMI outputs - one for video and one for audio? How about a game system?

It's crazy that anyone is even trying to justify this. It's not an issue of "button presses" or TV inputs, it's an issue of what's acceptable in a HT device. Two HDMI cables to get audio and video is simply unacceptable, period (except as a beta test, of course). HDMI AVR's are designed specifically to switch audio and video, period.

Crazy.

Now your argument is the "1 cable to rule them all". You previously mentioned video processing as a "feature" in an AVR. Again, if my AVR was processing my 1080p source, I WOULDN'T WANT it going through my AVR. No AVR is going to hold a candle to a proper video processor like a Lumagen or something. I agree that 2 cables isn't ideal, and "1 cable for audo and video" is the dream. But it's been how many years since HDMI has been around and here we are in 2008 and vendors are still treating HDMI audio as an afterthought. Whatever gets you the best video and audio with the equipment you have is what is important, not the number of cables. However, this is from an "in-home" point of view. As a consumer, I agree we need to pressure every vendor to provide proper (=interoperable) HDMI implementations.

I wouldn't buy this one yet, but maybe once the drivers mature and the 'kinks' are worked out, this Geforce 8200-based Jetway Mini-ITX board will be a lot of fun to insert in unique cases. Bit-tech seems to really like it, too.
post #944 of 2308
Note the reviewer says it is only SPDIF over HDMI for the Jetway 8200.

That is a bit puzzling. The Bios screen in the review shows an entry for HDMI audio. Why would you have to do SPDIF over HDMI? I can't visualize the connection, or need for one, at all Looking at the picture of their test setup on page 5 of the review, I don't think they even tried to get HDMI audio. They have a DVI cable and plugs into the analog out ports.

Pretty sure what they mean is SPDIF capable audio (5.1 DTS / DD and 2 channel PCM. No 7.1 LCPM or bitstreaming of HD audio). The audio signal would still be transmitted over the HDMI cable.
post #947 of 2308
Here is the actual statement I was refering to:
"Like the standard S/PDIF pass through on the 780G's UVD engine, the Nvidia GeForce 8200 PureVideo HD engine is also limited to an S/PDIF pass through"
It is not just for the reviewed motherboard, they are claiming this for the chipset! And not as driver- or board- dependent...
post #948 of 2308
I don't think that's correct. There are a couple of forum members achieving 8 channel LPCM with the 8200 mobo.

Did you happen to notice the title of this thread I still assert that they didn't actually test HDMI audio in that review!

Oh I noticed the title of the thread, what I misunderstood was your previous post about not being able to visualize the connection. Disregard...

NVIDIA has removed 5.1 LPCM support from the drivers for the 8200/8300/750a/780a chipsets. I am working with them tonight on an answer as to why they did this and getting them to specifically support 5.1 again. With the latest driver sets, you are limited to 2-channel or 7.1 LPCM over HDMI from these chipsets.
post #952 of 2308
what's the best (with least problems) 8200 board out there ? Is it even worth getting 8200 board right now ? Or will 7800 be a better option ?
post #953 of 2308
So, does the mini ITX jetway 8200 board do LPCM or not? DO we have a definitive answer? I realize that definitive answers here are far and few in between. I was going to pick one of those up...

Personally, I would stay AWWAAAAAAAAAAAAAAAAAAAAAAAAAAAAY from Jetway. I built by carputer with a Jetway board and had nothing but problems

Wow that's a really poor decision considering the majority of film soundtracks are 5.1.

Ajamills, I generally agree with you, but the itx form factor is intriguing.

Did some tests with PowerDVD8 ultra, results:

Identity Blu-Ray. AVC with uncompressed 5.1 PCM, works with HA off. Sound stutters with HA ON!

Batman Begins HD-DVD. VC1 with TrueHD works with HA ON!

Payback HD-DVD. AVC with Dolby Digital Plus works with HA ON!

The Descent Blu-Ray. AVC with Uncompressed 6.1 PCM works with HA ON!

Seems Identity is strange, and I will admit finally that PowerDVD8 ultra is superior to Nero as it displays menus properly!

Guys this is with a Phenom 9550 on the Asus Geforce 8200 uATX board. No discrete gpu in this machine as it's in a Silverstone HTPC case, so heat is obviously an issue. Pair up this baby with PowerDVD and you're good to go! Any requests out there?

Yes only using ONE HDMI cable to AVR, still had to use AnyDVD HD to beat the protection though

any requests?

which board are u using ?
post #959 of 2308
Thanks Renthx for posting your results. I've been waiting along time for such a setup.

I actually prefer the option of separate Video/Audio connections.

I run one source (HTPC), one AVR and Speakers and multiple output displays (Flat Screen/Projector). There are not many receivers supporting display switching and I prefer to have my Video unmolested anyway, direct from the HTPC to the display device and have no need for audio switching.

I think telling everyone a particular method is stupid is akin to trying to force a certain religion. Different people have different needs and requirements.

HTPC's should aim to be more flexible than BD players etc. Ultimately the option to either support either method (combined/separate) through multiple hdmi outputs gives total flexibility.
post #960 of 2308
So what are the best drivers to use with a GeForce 8200 motherboard (HDMI audio driver, display driver and chipset driver) ?
