  • Rough Playback, Slow Renders, CPU Maxed out

    Posted by Tim Neighbors on May 14, 2013 at 5:38 pm

    I have a quad core 2.4GHz that seems to not cut video in Vegas 12 like it once did. When I try to play DSLR video off the timeline (no effects or anything, single stream), it starts playing fine but over the course of about 30 seconds the framerate starts to drop until it is only playing back at 1 fps. Shrinking the video preview window and reducing to ‘draft’ quality does nothing to help. I have been editing DSLR footage with this PC for a long time, and although it’s had it’s struggles, it’s never been this bad. The CPU is pinned at 100% when playing back footage and it runs extremely hot (although heat has always been a prob. I downloaded a CPU tester software from CNET and it says it’s running at 2.4GHz exactly, although I don’t know that i trust that software.
    I recently installed some new RAM, a PCI to USB3 card, and a eSATA card and that’s when the problem seems to have started. At first it would just shut off without warning. I suspected CPU overheat, so I re-seated it with new thermal compound solution. The shutdowns stopped, but I started to notice the poor performance in Vegas. I have since removed the new ram and the problem persists. I don’t remember how I had the ram chips configured before (in which slots). Is there a certain way they should be installed? I have 4GB of ram (two 1GB cards and 1 2GB card). Right now I have them configured as 2,1,0,1 -with the first being closest to the CPU. The new RAM chips are two 2GB cards that are from a different manufacturer. There are 4 slots on my Intel DG33FB board.

    Any help is greatly appreciated. Editing is my livelihood, so this is a big prob.

    I’m going to assume you’re running Windows 7. In the ‘run’ box, type ‘msconfig’ (without the quotes). When the Windows Cofig window opens, click the ‘Startup’ tab. You’ll want to uncheck EVERYTHING except your anti-virus software. Then reboot the computer.

    Doing the above will free up system resources, and hopefully it’ll fix your issue.

    According to the Intel web site for your Intel DG33FB motherboard, you should be using matched pairs of memory. That means 4 x 1GB or 2 x 2G but you can’t use 3 DIMMS 1GB + 1GB + 2GB. Check the table for 4Gb and it says “Maximum capacity with four identical x8 Double-sided DIMMs“. “Identical” means that they all need to be the same.

    The Intel site also explains:

    Note: To be fully compliant with applicable DDR SDRAM memory specifications, the board should have DIMMs supporting the Serial Presence Detect (SPD) data structure. This allows the BIOS to read the SPD data and program the chipset to accurately configure memory settings for optimum performance. If non-SPD memory is installed, the BIOS tries to correctly configure the memory settings. Performance and reliability can be impacted or the DIMMs might not function under the designated frequency.

    So your memory may not be configured correctly which would cause instability.

    check if your power supply can deliver for the new hardware installed, also there might be compatibility issues, use latest drivers, contact manufacturers… as for the RAM you should have bought same stick, same manufacturer, same density and same latency (specially CAS)… the problem is not that as it persists without the new RAM but just a suggestion for the future.

    It could still be heat related – most CPU chips will “throttle down” if they get too hot. Tun Coretemp to monitor your CPU temperature while you are using Vegas. If the CPU temperature approaches Tj.Max, then there’s your problem.

    Tim, I think everyone is onto the right track.

    Have you tried reverting your configuration to as close to you can remember before the upgrade? You did not mention if you tried removing the eSATA or USB 3.0 card(s).

    Have a quick look in device manager and event viewer to see if any of the added card drivers (eSATA or USB 3.0) did not install correctly. If nothing appears amiss but your performance is still poor, remove the new components to see if you can get your system running to what it used to be, then individually re-add the new components. You might have a chance of detecting the culprit this way.

    My system specs: Intel i7 970, 12GB RAM, ASUS P6T, Vegas Pro 12 (x64), Windows 7 x64 Ultimate, Vegas Production Assistant 1.0, VASST Ultimate S Pro 4.1, Neat Video Pro 2.6
