Interesting as I get 0 dropped frames on 50i / 50p / 60i material on the i7 2600K 3000 iGPU using DDR3-1333 with MN. FYI - I agree with your EDID comments, I need to use a DVI (or HDMI) detective plus to stop issues when the "source" changes (AVR swithes away). I'm just not sure the upgrade to IVB is worth it.....
EDIT: Mem is Kingston KVR1333D3N9K2/8G 8GB KIT 1333MHz (PC3-10600) DDR3 NON-ECC CL9 240pin Last edited by jmone; 24th April 2012 at 10:37. |

Any way to bring up statistics similar to what is obtained in EVR-CP by pressing Ctrl-J ? |

How is memory speed related to an external GPU?
A good GPU won't make bad RAM go fast.

For subtitles I use vobsub (2.0 if I remember correctly) so I don't rely on the renderer. Not optimal but it works just fine and I mostly watch TV shows and movies with subs. I don't watch live TV through my HTPC so deinterlacing is hardly ever used. EVR-CP produced some performance problems (i7-2600) on some situations and provided lower quality than EVR. Sync issues exist but they are not that bad and mostly insignificant. It's not optimal but the whole setup is very simple (no dGPU). People have different setups and watch different content. For my needs the top priority are scaling quality and proper luma levels which work very well for me. I use very mild NR and sharpening. Mild settings on the total color control as well.

I don't see why one would need >1333 Mhz RAM to avoid dropped frames with madVR and hardware decoding like CUDA/QS. Even software decoding should work. |

If your CPUs memory controller is officially rated for 1600Mhz, you really should get 1600 (or above) RAM, otherwise you just do waste performance. Its not like there is a big price gap (if one at all).
That the iGPU benefits from the memory speed more then most CPU applications is one factor, but not the whole argument.

Test videos weren't easy: 1080p, 60fps, high bitrates and pure software decoding. My assumption is: If there are dropped frames with low memory frequency, the problem could be caused by something else. Quote:
Then you can have higher clocks which will be much more gainful. Last edited by aufkrawall; 24th April 2012 at 11:58. |

You really don't get the point. Oh well.
The point is that 1600Mhz RAM isn't more expensive then 1333Mhz RAM, both are about the same price around here, so when you get 1333 instead, you're just doing it wrong. The bonus that the iGPU really benefits from the 1600Mhz over the 1333Mhz is irrelevant for that fact (although something important to know if you want to use the iGPU) And no, overclocking won't help if your memory bandwidth is limiting.

Obviously that doesn't work with HDMI displays because every time the system resyncs with the display it "detects" a new display. The important thing is that they are now aware of the use case and issue with the current approach and have at the very least documented a change request. While I don't personally find that feature valuable, it should work properly for those who do. Quote:
I did most of my testing with 480i content and as long as FSE was enabled it worked quite well. |

I did get it, no worries.

I don't think so. But you also spoke of RAM with more than 2000 Mhz which doesn't make much sense at all. Quote:
As long as you don't plan to do massive encoding, anything faster than 1600 Mhz is pointless, waste of money. |

As i explained to jakmal earlier, 720p content is more computationally expensive to upscale to 1080p. He also confirmed that a 720p60 camcorder clip does not work flawlessly for him either. My scaling was mentioned earlier in the thread, MN for Chroma, Lanczos3 for Luma. Quote:
Its not like 2133 memory is extremely expensive or anything, i paid for the 8GB kit 60€. A similar kit (same brand and line) with 1600 was 50€ at the time. I don't mind the 10€, i never did try to go cheap on my PCs, and i'll not start now. If i run a 300€ CPU, the 10€ for better RAM won't hurt. Thinking about it, RAM has become so extremely cheap over the years....

The i3 route would've given me a better CPU but I had no need for that when using hardware decoding and deinterlacing, so I considered it a waste of money. If I were making the decision now, it'd be tougher because of the introduction of QuickSync and DXVA2 into LAV Filters, plus the fact that having a better CPU (i3 vs Celeron) would help with on-the-fly transcoding etc. *Celerons only support running DDR3 SDRAM at 1066 MHz but 1333 MHz RAM was actually cheaper at the time.

That's why I opted for the 2133 ram I got. It wasn't cheap, but, I will be doing TONS of encoding work on that machine. Personally, I'll be using my 5870 for output, but, I do want to try to get QS working for decoding and encoding in Media Converter. That would ROCK.

The stats were generated w/ your settings and FSE enabled w/ DDR3-1333. While it was running the render queue was in the 14-16 range. I dropped it back to windowed to take the screenshot. Not perfect, but not terrible either. When I get a chance I'll see if the results are any different w/ DDR3-1600. |

But I'm a a bit penny pinching when it's not about GPU power. I paid 40€ for 2x 4 GB 1333 Mhz in December. When I got SNB I just overclocked it to 1600. Quote:
