*Official* NVIDIA Kepler (6xx) GPUs for HTPCs - Page 8

Probably a bad VGA connector on your GT440 card, especially if the connector is attached via a ribbon cable and IDC connector, these sometimes go bad.

You might consider getting a replacement for the card.

Is forcing your FPS to 24 a hard thing to do? I would like to try this.

I just bought a new receiver: Harman Kardon AVR 1700, and hooked it up to my computer that has a GTX 650 ti via HDMI. The computer is running Windows 8 Pro. If I look at the audio properties, under the supported formats tab, I see DTS and Dolby Digital, but none of the HD formats (Master Audio / TrueHD). I have tried playing a sample .ts file for each of the new HD audio formats, and I don't get any audio. Any other audio format works fine. What do I need to do in order to play HD audio streams through my computer to my receiver?

The player you're using on the computer has to support bitstreaming those audio types.

I figured it out. Even though I had installed the newest Nvidia drivers, they didn't auto override the audio drivers. I manually installed the nvidia drivers for the audio device and then the supported formats showed up. Thanks for the reply!

help me decide.... HD7750 or GT640 for HTPC duty. I am looking for something that can get me 23.976 or 24fps. Can reclock be used with both Nvidia and GTI cards ?

I recently got the following card. There are some things a 7750 can't handle.

ASUS HD7770-1GD5

It's an easy fit being somewhat small and is very quiet and cool.

I am absolutely thrilled with the performance. There's no visible stuttering, frame drops, frame repeats, or video corruption and it handles 25fps PAL superbly. The timings are much better than any other card I've had so that I am only getting frame drop or repeat in the days rather than minutes or seconds. Some examples.

23.976: actual 23.97609
29.970: actual 29.97021
30.000: actual 29.99997
50.000: actual 50.00017
59.940: actual 59.94037

Here are the rendering times using madVR Jinc3+AR for chroma and image upscaling to 1080

1080 6.31 ms
480 8.34 ms
720 11.54 ms

My keplar based GPU card, the GT640, can lock onto 24.000Hz (and 59.940hz) pretty easily.  If you want an authentic cinema experience, you would actually want your refresh rate to be 24.000Hz synched with Reclock "Cinema" frame rate of 24.000fps, not 23,976Hz.  Video reproduction doesnt get any better than that.  Having said that, I have a feeling both ATI and Nvidia cards can lock onto 24.000hz equally as well; producing comparable picture quality on both brands.  I just picked Nvidia because their control panel GUI has a much nicer (and easier to use) layout than the Catalyst equivalent.  BTW:  If you use a normal 1080p TV and bluray material, you wont need MadVR... just plan reclock+EVR would be more enough.

Thanks, I agree with you and thanks for making me remember the really bad Catalyst GUI. I had an old 5550 and remember the catylyst driver GUI was not that great. I think I am going to pick up that GT640. It should be a huge improvement over the Corei3 IGP.

Can the GTX680 do 4K ( or UHD 3840x 2160P at 24,25 and 30P ) or not ?


TIA

Hi, I have the same problem here, but with a msi gtx 660, and windows 7. I cannot bitstream HD Audio like DTS HD and TrueHD, and in the audio control panel those formats are not showed. My HT receiver is an Onkyo sr 508. I know it works fine with DTS HD MA, because when playing blue ray through Playstation 3 slim it does bitstream correctly.



How can i make it work? I tried several video players ( all versions of Power DVD, XMBC and Media Player classic Home cinema) , and tried also older nvidia driver, but it' simoly not working. All i can send to the receiver is PCM 24 bit 5.1, or lossy DTS Core trhough HDMI.

Hi everyone, new here. Can somebody help me to choose which car is better for my HTPC-Gamer PC. My options are: Sapphire 7950 Vapor-X and asus gtx 670 direc cu ii (non Top).
I own a sapphire 6670 and works perfect, no issues. Never try a nvidia and have some doubts about the drivers for the HTPC purpose.
I want the most quiet card, i've read some reviews from those cards but i'm no clear which one is the quietest.
I know that the 7950 is cheaper and if i overclock it can performance like 670, but i really want to avoid the hard overclock because i'm afraid that the card turns too loud.

So, 670 looks good for the gaming performance but i don`t know if it would be great for the HTPC since i`ve read this thread and looks like the nvidia drivers doesn't do very well. I play mostly videos in 23 hz mode (23.96), but also 24, 25, 29, 50 and 60, with madVr switching automatically the refresh rate.

By the other hand, i know that the 7950 will work like HTPC, because i know the amd drivers, and for the gaming purpose too, but i don't know how far i have to go with the overclock to max out like 670, and doing that i don't know how much louder the card will be.

I hope somebody help me.
Thanks.

Most game developers do most of their development and beta testing on Nvidia based PCs.  I know that because I used to work for a very large gaming company.  You're probably going to get the best gaming experience with Nvidia since they work on a daily basis with game developers to produce frequent driver updates specifically optimized for popular games.

 

It would be good idea to get the fastest card that's compatible with your system without trying to overclock it.  Most higher end cards are already maxed out in clock frequencies.  I doubt you would get much real benefit in overclocking without introducing heating/stability related issues (loud fan noise, system lockups or reboots, graphics distortion,etc).  Both ATI and Nvida have their share of driver related glitches in respect to HTPC related tasks.  Nvidia also has CUDA based hardware acceleration; which many 3rd party software developers have supported for years.  I personally use CUDA acceleration for a bunch of different software (Splashtop Remote desktop, Wondershare Media Converter, LAV video decoder, etc).

 

It looks like, getting the fastest single Nvidia card your PSU can handle, would be best; if money is no object.

 

Thanks MKNET.

I really like the idea to get the 670 over the 7950, it have great performance without tweaking and has some cool stuff like CUDA and Physx.

The build is totally new. I'm getting a i5 3570k, asus z77 and a PSU above 600W.

Just a gonna know tow simple things about the Nvidia drivers.

I don't use the 3D (i don't like it) so, it will be a problem setting the 23p,24p,25p,29p,30p,50p and 60p modes??? And can i put the RGB Limited Studio in those modes without too many troubles??

Looks like some of the problems about 23.96 fps is when use the 3D Vision. I'm no sure, just tellin'

Thanks again.

I just have a low-end Keplar card; since I dont use my htpc for games.  I only use my HTPC for watching 2D/3D Bluray and 1080i/720p TV; I dont have any issues with refresh rates.  The Nvidia card handles 24.000FPS/24.000Hz or 59.940fps/59.940Hz very well... smooth as silk on my Samsung D8000 LCD TV.  I'm not sure what all the fuss is about regarding 23.976hz; especially, when you get nicer/more pleasant video/audio playback at the original 24.000fps speed; which Nvidia cards can definitely handle very well (I use Reclock to return to original Cinema speed).  I dont use MadVR since it wouldn't make any real difference on the display resolutions I use.

 

I had to apply a tweak to my Nvidia driver before installing it in order to get "real" 0-255RGB on it's default 1080p/720p HDMI resolutions; otherwise, the colors aren't right.  Also, when watching 3D bluray, I have to manually enable Nvidia 3D mode before starting the movie; since it has to share it's 1080p/24Hz resolution settings between 2D and 3D modes.  On ATI, its fully automatic.

 

 

I would point out an issue I am having with Nvidia and cable TV playback from a Ceton. I have started a topic to which no one has yet responded. Anyway, I get audio break on certain cable channels. CNNHD for example will drop audio at the same places in certain commercials. A behavior that does not occure with the iGPU. The occurs with both a GTS 450 and a GTX 454. The video is much smoother than the intel graphics but I can't fix the audio issue and it has prevented me from buying something like the GTX 650Ti Boost.

I just ordered an HIS Radeon HD 7790. I really prefer Nvidia due to general driver stability but I can't get past this issue with cable TV and Nvidia. I have duplicated it on W7 32 and 64 bit and on H67 (intel board) and an H61.

The default 23Hz refresh rate is the worst (~23.971Hz), so you will have to do either of the two:

1. Create a custom resolution. Then output B&W levels will be only full range RGB at 23Hz.
2. Use ReClock (or JRiver MC's VideoClock) with media adaptation (then you will lose compressed audio bitstreaming, no real problem, though).

Thanks for your answers. Very helpful.

A 600W PSU will be more than ample for a single GTX670 as they are very energy efficient cards. I've overclocked both my i7 and GTX670 on my gaming rig and it draws at most 350W under a full system stress test based on the reading from my UPS.

The ASUS GTX670 Direct CU II has one of the best stock GPU coolers on the market, and you should be able to easily squeeze significant extra performance from the GPU through an overclock without introducing too much instability. There is a great guide at www.overclock.net/t/1265110/the-gtx-670-overclocking-master-guide/. It takes probably 3-4 hours to find the maximum stable overclock, but once you've found that point it's pretty robust. The biggest gains come from overclocking the VRAM and when combined with increasing the GPU clock will give you the equivalent performance above a stock GTX680. Overclocking may add 5-10C to the GPU temps at full load, but the way the kepler series is designed it adjusts the GPU clock based on load. Running MadVR mine never goes over 7% load and the GPU fans stay around 20-25% which is inaudible. I have it set for the fan speed to peak at 55% when gaming and it is only just audible at that point. It's very easy to set custom fan curves based on your desired noise levels. The overclocking software also allows you to save different settings profiles, so you can have one setup with stock settings, and then another overclocked profile which you can switch to when you need the extra grunt.

Hi guys need some help,

I hooked up my Denon 1713 to my EVGA 660 Ti card and I'm not getting any sound, what exactly is the problem? I did download the latest drivers.

Nevermind I got it.

Exactly the same problem here with a Gigabyte GTX660 Ti on Windows 7 connected to a Denon AVR-1910. No HD audio formats are shown under the supported formats tab in the audio control panel. I've made sure that the correct HD audio driver is used but still nothing. Marco, have you found a solution?

Maybe you guys will find this thread of some use, let me know if it works.

Thanks, turned out I had an EDID-problem. Solved by using a modified monitor driver/inf file.

AMD recently kicked up the notch with their "Never Settle" campaign. They seem to have more A-list titles now.
In addition, considering AMD also scored design wins for the next generation Microsoft and Sony consoles, it won't be surprising to see if the new games ported from consoles all suddenly run better on AMD architecture.

I maybe the only one in the world who is reporting this bug but I am seeing audio and video glitches in WMC with cable content using Nvidia. This occurs only on Ceton. My provider is Comcast. On CNNHD for example the audio will stutter during commercials but not actual news programming. I have seen this with both a GTS450 and a GTX545. The same Ceton Comcast material plays via these cards fine in JRiver MC.The issue is very annoying and on some cable channels it is both commercials and programming misbehaving.

Intel and AMD do no exhibit this bug which can cause all the content on certain cable channels in WMC to have audio stutter. Stutter is probably the wrong word as the audio drops out and will come back on at some point or it might the whole commercial that does it, or just a certain portion. Whenever that commercail plays the audio defect exhibits at exactly the same time for the same duration.

I generally prefer Nvidia but since I could find no resolution to my audio issues I went with AMD, otherwise I would have looked at a GT 650Ti Boost.

Anyway, for my main HTPC I invested in an HD 7790 and it is working well for WMC and JRiver with ATSC and Cable. I use MadVR in JRiver and I did overclock the board slightly as I am using Jinc 3 AR. I find it runs slightly smoother with the 15% overclock.I had tried an HD 7770 and while it was very good in WMC it would not handle Jinc3 AR in MadVR without frames drops on 1080i content.
