Again? Best slot in Mac for Kona LHe…

[Garrett King]

Hi Bob… I am having the same exact issue capturing with my Kona LHE on a 2007 MAC Pro with 5 gigs of Ram and with 2 Dual – Intel processor with speed = 2.66 GHz. I have my NVIDIA GeForce 7300 GT card in slot 1, Slot 2 is a firewire card with two 800 slots and a 400 slot, Kona LHE in slot 3, and slot 4 is a fiber card that isn’t used all the time; only when we switch to the Avid partition, in fact it gets unplugged when not in use. I have a Gen 10 and that is hooked up with black reference going to the deck and the computer. Im only trying to capture Apple Pro Res NTSC 29.97 which is a very low bandwidth and according to the Aja system test and Data rate Calculator should capture with ease to a two TB G-raid connected with firewire 800. I have also tried capturing to the Computers Hard-dive. I am having Audio slip that get progressively worse the longer it captures. I notice it is off any during playback. It begins to slip not even 30 seconds in.

I’ve been watching this thread with interest. We have a LHe in slot 3 on a 2008 MacPro 2.8 Octo Core. Running FCP 6.06 and with the latest AJA v6 drivers.

It seems to work quite well…. but after reading the exchange we’re thinking that maybe we should move the card to slot 2. Sometimes we do get dropped frames, but it is not very often. Otherwise it works fine – the rare FCP quitting out – but that’s probably an FCP bug.

Anyway, thought I’d chime in with some LHe “slot 3” experience.
