You're right, blacksheep.
I forgot to fix on it.
Well I've done it this time but no signal.
Please give me a last suggestion.
About to give up on this card.

Should work, weird. Some questions you need to answer:

Have you tested the card before flashing? Does it work unflashed?
What OS you're running and which port did you try? DVI, DP, HDMI?
Could you login remotely to see if the card is recognized properly?

Thanks again, blacksheep.

Before flashing, it displayed blue screen once and signaled off when I tried on Mac Pro 2008 with 10.8.3.
System profile said "HD5000" then.
Never tested on Windows machine.
I only plugged to DVI.
I could have logged in remote from MacBook but at the moment I took the 5770 out from the machine-kind of giving up on it.

The card itself has a problem, you think?
I got it from auction in Japan.

Thanks. Maro_jp

Yes, if it acts like this before flashing, it's DOA.
It should work unflashed with 10.8.
You can test it in a PC as well if you have one by the hand.
Even flashed with EFI ROM should work normally in PC box.

Thanks for hanging out with me for a while, blacksheep.
I guess I will look for another card since my old flashed 4870 is dying.

Thanks again, blacksheep and people at this community.

Hi to all!

I apologise if I missed it in this thread - I gave a question; which efi rom would be best for my Gigabyte GV-R577UD-1GD (Rev. 1.0)? I have a Mac Pro 3.1 (2008 8core). I am using nVidia's GT120 which is OK, but some performance boost is in order and recently got one of these 5770's.

 Thank you for your help  Wink

Awesome forum, btw!
