UHD video support for DZ77GA-70K

[PChou3]

I have an Intel mobo DZ77GA-70K. I want to know if there are any video cards that would work with this 5 year old mobo that would support UHD/4K monitors (3840x2160).

I recently purchased a GEForce GTX 1050Ti card from EVGA, however, the mobo will not boot with this video card.

This is your board:

It has 2 PCIe x16 3.0 slots, so you should be able to use an add-on card that is PCIe 3.0 compatible.

Possible issues you are experiencing:

• Power supply problem?
• Does EVGA include support for only UEFI boot, and not Legacy boot on your card?
• Are you at the latest bios for your board?

The search for a card to support your UHD/4K is something you will have to search for. However, the solution may be solved by addressing the issues I have provided above.

I think the easiest is to check if you are doing a UEFI boot or not. Go into the BIOS and check this.

You did not mention your OS. Also, changing from legacy boot to UEFI boot may require you to reinstall your OS.

I have a 850W power supply, so that is unlikely to be the issue. When the card is installed, it does display the Intel skull logo on boot up, but that's all it ever shows.

The operating system is Windows 10-64 Pro.

The BIOS version is GAZ7711H.86A.0021.2012.0222.2054. I do not see where/how to update the BIOS. The drivers page for this mobo doesn't show anything about BIOS updates.

There's nothing on the box of the video card or in the installation manual that talks about Legacy bootup.

The mobo BIOS is wa not using UEFI when I posted the original message.

I have just switched the BIOS to use UEFI and the operating system boots fine.

I have not tried installing the new card again since it caused me more than an hour's lost time when I last tried it (before making the UEFI boot change). I won't try again until we verify the BIOS version issue.

Thanks.

FWIW, the Intel® Driver & Support Assistant took, when launched to "Check for new drivers" causes Edge to jump to www.intel.com/content/www/us/en/support/intel-driver-support-assistant.html where I am told to wait until the following red banner appears:https://www.intel.com/content/www/us/en/support/intel-driver-support-assistant.html

The rating of the power supply does not mean it is not at fault.

Windows 10 is not supported on your motherboard. That does not mean Windows 10 will not run.

That is not your bios revision. You can get the latest bios here:

There will likely be nothing on the box to tell you this. Your board is six years old. Many using such a fancy video card also want a newer board to take advantage of the features and performance of the card. Best to ask nvidia or evga about their support.

I would update the bios, then check the card. Follow the instructions, and use the F7 method with a USB stick. The stick should be a full format with fat32 from your Windows machine.

When windows 10 is running, go to the RUNcommand and enter MSINFO32. Check to see if your bios mode is UEFI.

By the way, your bios is 0021, the latest is 0066.

Would it be possible to replace the motherboard and keep the processor and RAM? It would be a shame to through $600+ worth of process and RAM down the drain if we are only talking about the motherboard being out of date.

[AlHill]

Well, your processor and memory are also out of date. Remember, your board is 6 years old. You are using DDR3 memory, the current world is using DDR4 memory. Your processor is likely a 2nd or 3rd gen processor, the current world is using 7th and 8th gen processors.

And, Intel no longer makes desktop boards, so you will have to research what manufacturers do have boards that are compatible with your processor and memory, if any.

I place some doubt on your price evaluation of the processor and memory. Maybe 6 years ago it was worth that much.

And, if you are a 2nd gen processor, you are not supported on Windows 10.

Are you not willing to update the BIOS on your current board?

I upgraded the BIOS.

I installed the new 1050Ti video card. It is working.

As far as the CPU is concerned, the mobo is using Intel Core i7-3770K Quad-Core Processor 3.5 GHz 8 MB Cache LGA 1155 - BX80637I73770K. Is this a 2nd generation chip?

[AlHill]

Glad it is working!

Your processor is a 3rd gen processor Ivy Bridge processor and is supported on Windows 10 64-bit.

Did you run MSINFO32 to check the bios mode? Not really important since you are running the evga card, but I am just curious.

To run MSINFO32, right-click on the start button, select run, and enter msinfo32. Then check the summary page for BIOS MODE.

Doc

[PChou3]

Even though I had set the boot mode to UEFI prior to upgrading the BIOS, the msinfo32 shows I am using Legacy mode. Don't know if upgrading the BIOS destroyed my UEFI boot setting.

Here's the msinfo32 data.

[AlHill]

Well, let us leave well enough alone at this point since the card is working.
