64 bit questions / solutions

hi,

sorry if this is in the wrong forum but it looks like the best bet... anyway, here's the situation & questions


We have a new mac pro with a 5770 card. Many issues... First is it will only run 32 not 64 bit and even then the LFG input & Intentsity Pro cards can bring the os down when you enable it with various other random crashes, however once its running its solid. We have 2 THTG Dvi cards on the outputs and using the MDP - DVI adaptor the only resolution is 2400 / 600, whereas the dual link Dvi output works fine. However you can only use 2 out of 3 of the outputs at any time. I'm told that if we buy the Apple active MDP - DVI it will all work a treat giving 3 dual link DVI outs , but I'd be happy with 2.

Questions basically are...


Will apple fix the 5770 drivers anytime soon ? even then its going to need another adaptor if not 2 to work properly so is there any point waiting?


Does anyone any experience of the MDP Active DVI adaptor ?


Would the sensible move be to junk it for a GTX285 ?


Whats stopping Catalyst / Lfg whatever working in 64 bit and how likely is a fix for that?


Advice much apprecciated!

you have to reboot macs in 32 bit mode - 64 bit mode is mostly just completely pointless - there isnt any performance advantage at all. its all hype. and bullshit -
5 years ago powerpc was all 64 bit -

ATI cards are currently broken - 5770/5870/4870 on 10.6.4/5 as of today 11nov2010 - nothing to do with 32/64 bit - drivers are broken in both.
gtx 285 is end of life - probably being replaced by gtx 580- but not much news on hacking sites
http://netkas.org/
and
http://www.mvktech.net/index.php?opt...id=10&id=59277

th2go issues are between matrox and apple - and drivers - what works and doesnt is completely up to them - and technical mini display port adaptor limitations.

apple did not port quicktime properly to 64bit - and they never will - so they said - who knows what they will junk or break along the way. quicktime X - their recent player was fundamentally an awful downgrade in functionality - someone forgot quicktime design paradigm at apple -

Thats fine - there is no performance gain in 64bit mode and many drivers are not yet supporting 64bit.
Stick with 32bit.

To select the 32-bit kernel for the current startup disk, use the following command in Terminal:
sudo systemsetup -setkernelbootarchitecture i386

LFG should not do this in 32bit mode. Try removing Intensity Pro - use a new blank catalyst show and try again.
Try re-install drivers from Active Silicon website:

Check your settings as above and re-install latest driver
What version of catalyst are you using? Richard has a workaround that may work for Decklink Cards.

The MDP-DVI adaptor is single link - ie you will only get limited resolutions out of a Matrox TH2G
Either use the Matrox TH2G-DP edition (with a plethora of adaptor cables) or use a MDP-DVI-D active adaptor from apple (£60.00)

Have you checked how many you can use without a TH2G.
There is a limit to what a graphics card can do....

Not necessarily 3x DVI-D outputs.... but you should get 2...

Impossible to answer - apparently there may be some hope in the OS build after next...
Do wait - on paper the 5870 card could be good...
The existing adaptors will do the same as they do now.... resolutions wont change.

MDP-DVI-D adaptor works - you must test it to see what it does with the TH2G

Dont junk it - leave it on the shelf for a few months
If you can get a GTX285 - it will be a better choice than 5770/5870 right now (11/11/10)
Else use a GT120 - its cheap, works ok and is a good interim solution.

AS drivers are 32bit
nothing else takes advantage of 64bit at the moment - so no reason to run it...


basically - follow the guidelines and workarounds here on the forum and new MacPros work fine if you run them in 32bit with an nvidia graphics card.

no ati cards currently work well enough- they all have the same texture upload problem in 10.6.4/5
4870- 5770 5870-
its not fixed in todays 10.6.5 release.


gt120 is simply not good enough to run more than a couple of low res outputs- it overloads easily with triple heads.
gtx 285 as the best option for most of this year.

quicktime video digitisers dont work in 64 bit mode - apple never ported the API to 64 bit - IE any decklink or aja model-

everything needs to run in 32 bit modes.
