H20 on Windows 7 64-bit 'isochronos' connection error.
Hi
Hardware & software: New PC running Windows 7 64-bit, i17 920 2.16 gHz quad-core, 6gb triple channel RAM, PhaseOne recommended SIG Firewire card, Capture One 5.1, PhaseOne 64-bit driver 1.50.1.34019, H20 on Mamiya RZ.
Problem: Despite being assured by PhaseOne that this would work before the new computer was built, it doesn't. Connecting the H20 gives the 'isochronos' (asynchronous) error. Windows Device Manager confirms the H20 is connected and working correctly. Various other Firewire cards (all Texas Instruments chip-sets) have been tested but all give same error. PhaseOne suggested a 'legacy' Windows Firewire driver. This connects the camera to C1 but firing causes immediate 'blue screen' total system crash. Nothing else so far suggested by PhaseOne works.
The only way we can get the camera to connect to C1 is to remove 4 gb. RAM reducing total to 2gb. The issue seems to be that the PhaseOne 64-bit driver does not work with 4gb. RAM or more and I don't seem to be alone in experiencing this problem.
Has anyone out there successfully shot tethered with an H20 (or any other back) using Windows 7 64-bit with 4gb. RAM or more? This has been going on for three weeks now.
Regards
Mark Sykes

Mark,
Please read the following link;

However, the 4GB issue should not be a problem any longer with the release of 5.1. As such perhaps an uninstall and reinstall is a better solution.0 -
Hi Drew
Thanks for your reply. Obviously I have read the article at the link before the machine was built and again since just to see if I was missing something. Since the machine was a clean install from new with no other drivers or versions of Capture One, I can' see that a clean removal and re-install will achieve anything other than take me back to the initial state, as Lee has mentioned in our tech support case.

I see.
Well, as Jon mentioned on your other post (viewtopic.php?f=20&t=7721&st=0&sk=t&sd=a&start=15#p36497) you are certainly in capable hands within the support case. I would recommend following up with that cases suggestions and we'll certainly get to the bottom of it.
I believe it left off with the following suggestion;

Despite there being no previous drivers present, the above suggestion is certainly worth a shot.0
