GTX660 startup

My (new to me) Mac Pro 8-core 2009, 2 x 2.26GHz has inherited the Zotac GTX660 card from my Hackintosh.

The card works well but displays the issue noted elsewhere on this forum, namely that there is no Apple splash screen at start, which would make a fresh OS install difficult. I have retained the stock GT120 if ever needed for that purpose. Further, the common temperature utilities fail to report GPU temperature, something they do fine with the stock card.

My question is: Is it possible to flash the ROM of the GTX660 to work around this issue?

My Unigine score is attached if it is of interest:

Thank you.

I updated from 4,1 to 5,1 and the red in the attachment is my current ROM for the Mac Pro.

The GTX660 ROM is in the second attachment.

What you attached is not what I want.

Sorry, I do not have Windows. Is there any workaround to get you what you need?

That's OK.
Please send me the picture of card.
I could find the rom on the techPowerUP website.
If I post the modded rom, how do you flash it into your card ?
Flashing card needs a PC with windows system.

A picture is attached, together with the predecessor 9800GTX+.

If that is not sharp enough I can take the card out of the Mac Pro and try and make a better one.

The card is a standard 2GB Zotac nVidia GTX660. There is no specific model number on the box or in the instructions other than 'GTX660'.

As for the Windows dilemma, I will get access to a machine with Windows.

Thank you.

Bump. Anybody?

Does anybody offer this as a paid service for those of us without Windows? MacVidCards?

Bumping isn't allowed on MR
MVC is on vacation until 8 Jul AFAIK.
Contact him directly via PM or his eBay shop.

Another thing that came into my head: does GTX 660 have 256K chip needed for Nvidia EFI ROM?
