Mojo SDI analog output dropped frames
I have tried to find a solution to Mojo SDI analog output dropped frames. My system: asus Maximus III Formula motherboard (No overclocking), Intel i7 Quad Core 2.8Ghz processor, 8GB PC3-10600 DDR3 Ram, BFG GeForce GTX 275 896MB GDDR3 Graphics, 2X Seagate 1.5TB Barracuda Raid 0, Vista Business 32bit SP1, PYRO PCI 64R2 Firewire Card Texas Instrument chipset (Avid Compatible) (IRQ22 not sharing any devices), Media Composer 3.1.3.2 (Academic Dongle: registered). No frames dropped on main user interface. Dropped frames and jagged audio on playback. Transcoded from AVCHD AVI source clips using Main Concept Transcoder and imported to AVID MXF files. I have also tried a Mojo DNA, XP Pro 32bit , Vista Business 64bit, Vista Ultimate 64bit, Windows7 Ultimate 64bit. I have edited boot option for 2700 MB virtual memory on 32bit OS’s. Is there something I’m Missing?

Hi
This could be 1 of two things:
1: Your firewire card. Have you tried another card or put the one you’ve got in another PCI slot? Avid is particularly iffy when it comes to the cards they like.
2: Your RAID 0 config. Raiding is actually not always the best way to go, I’d try setting up my drives separately in plain old SATA mode and see what happens. Also try using an external drive like a G-Raid and see what happens.I’m running a Mojo SDI on older equipment (Quad Core, 4 gigs Ram, Xp 32-Bit) and my system is as smooth as silk.
Hope this helps.
Cheers

The dropped frames show up on the Mojo output only. It is fine on the computer monitor. My firewire card is Avid approved Texas Instruments chipset. I also checked the IRQ and made sure no other devices were on that IRQ 23. I moved the Mojo over to my old HP and it works fine. It won’t do much layering without rendering.
OH well. Maybe the new Pentium i7 Quad core with Hyperthreading Processor is creating a bottleneck somewhere.

Hi Steven,
We got the same problem. I have upgraded to P8Z68-M Motherboard with i7 2600k processor and 4 GB memory. AVID mojo works fine on my old and slow system but in the new system its not working. Did you manage to have you Mojo SDI running?
Thank you,
Oliver

I found that Avid prefers HP Workstations because you can allocate IRQs. My ASUS motherboard BIOS settings do not allow hard IRQ allocation. AVID MOJO and Adrenalin need a firewire card dedicated IRQ channel without any other devices on it.
