SS,

Can you tell me where you are finding the information about the minumum spec's for MEP.  I would think the new card should have exceeded the requirements of a graphic card I currently have that was produced in 2008.  I have tryed to find the spec's for MEP , but have been unsuccessful.

JUst to  be clear from the information you wrote, That the Memory Interface Bus width of at least 256 bitfor .

I am not very technically inclined , so I am not really  sure what you mean by 256 bit for GDDR3 and 128 bit for GDDR5.

Then you stated GDDR3 730 has only max 128bit and the GDDR5 has only 64 bit.  Does the GDDR3 and GDDR 5 refer to?

The card I had before the replacement had the following spec's, and MEP 2015 ran without issue.

I would appreicate a little simpler explaination.

Thanks again

Hi Papadewey

I can not at present direct you to the place where it is stated but it is definitely an official recommendation from Magix on their Sales or Support site. Having said that there may be cards that buck the trend  as in your older card, even though this appears to have a 128Bit interface and only GDDR2 memory. Your new card has only a 64bit bus and even though it has GDDR5 memory the bus may be just too narrow for MEP's requirements.

The memory bus is the connection between the Graphics Processing Unit (GPU) and the dedicated graphics memory on the card. This determines how much and how quickly data can be pushed backwards and forwards between the two. GDDR3 is slower so it needs a bigger bus width to move the same amount of data as newer GDDR5 memory, hence the difference in specs of 256bit and 128bit respectively to meet the minimum reqirements.

What happens if you select "Compatibility mode" or "Alternative mode1" in the Display options > Video Mode window in the MEP program settings (Y key) before starting playback?

Thanks for the more detailed explaination.  I pulled the new card and replaced the old one, so I could do some editing..  So give me a day or so to try plug the new card back in, and try your idea about compatibility mode or Alternate mode 1, to see if that solves the issue. If the new graphic card is the problem, maybe I need to look for a faster, or better card that meets MEP requirements rather than try to find a work around for one that does not.

I will be in touch.

Hi

I agree with SS that the issue is related to the GT 730, however for a different reason - the Nvidia graphics chip based cards use CUDA whereas your old card does not.  IIRC there has been an issue with CUDA on some GT graphics cards and you have to install an older version of the drivers for the CUDA to work correctly.

However before doing anything else, what is your computer specification - in particular which processor model and speed do you have?

Thanks to all that responded, to this question regarding the Graphic card issue with MEP 2015, I have tryed all the solutions that have been suggested, and they all fail to solve the problem.  I will be sending the 730 back, and will use the video card that has been working all along.  I hate to throw in the towel, but some times you just have to cut your loses.

Hi Papadewey

I think this is pragmatic. I would choose a higher spec card in future if I was you, although I can not totally guarantee the problems are being caused by limitations I mentioned.

Cuda is not used when MEP is previewing the timeline to my knowledge, only for Hardware Export rendering with the Mainconcept encoder. Also it is not the drivers but the Firmware used in the Graphics chips from Nvidia Geforce 6xxx Series on, that would not work with the Cuda encoding, because Mainconcept would not supply a suitable SDK to Magix to suit the newer firmware. since then Magix have given up on Cuda export rendering.
