Mladen7, thanks a lot for asking before proceeding with the update of the BIOS on your motherboard.
This specific model has 15 different BIOS versions, which means there are many fixes between one and another and I do not recommend you to install the latest version at first. Sometimes, it does not include all the fixes and upgrades from previous BIOS.
What we recommend customers to do is to check how many versions are between the current BIOS and the latest one. Then, depending on that, install or flash 1 or 2 versions before getting to the latest one. In your case since you have the original BIOS, you may need to install a few more.
You can try to install BIOS v0035 and then, depending on the issues you are experiencing with your board, start flashing the ones you need, but at least installed three.
I would recommend you to use the F7 method, since it is more accurate. Desktop Boards — BIOS update instructions
Thanks Sylvia ...
I worked one on one upgrade BIOS 0027-0066 method that you have recommended. They have successfully completed all the upgrades except the 0059, which was a problem because we do not go away, so I moved on to the next and so reached the last 0066th The board works great and more generally do not notice any problems.
Once again a big thank you for your help.
You are more than welcome Mladen.

Hello Jayesh Soni, thanks for joining the Intel Community.
The processor and the motherboard are totally compatible.
This specific board has 15 BIOS versions available. I would like to tell you that going straight to the latest version shouldn't be a problem, technically speaking. However based on experience, there is always chance.
I would recommend checking the BIOS Update Release Notes on this URL. You will be able to see the fixes and features included on each version.
Please install these BIOS versions
BIOS Version 0035
BIOS Version 0045
BIOS Version 0049
BIOS Version 0053
BIOS Version 0061
BIOS Version 0066
Thanks Silvia L for fast and informative reply,
One more thing I want to know-- I have already installed WIN 8.1 PRO on ssd, can I install that ssd on DZ77GA-70K with bios ver 21 or need to reinstall that os again ?
You can try Jayesh, however sometimes if the chipset is different, the board is not going to be able to boot to the OS using that SSD.
Thanks again sylvia , bought the board with 2 years intel warranty, Install SSD having WIN 8.1 . Took some time to getting device ready and started. WOW amazing and satisfied.
