NVIDIA K620 Graphics Card Questions

[Kelly170]

Before I buy a NVIDIA K620 Graphics Card off of Ebay, I was wondering if it is even compatible with my system:

CPU: Intel 4790 at 3.60 GHZ with boost clock up to 4.00 GHZ

GPU: Intel Integrated 4600 192 Megabytes

MOTHERBOARD: HP 1998

POWER SUPPLY: Standard HP 320 Watt

SLOT NEEDED FOR GPU ON MOTHERBOARD: Yes

OPERATING SYSTEM: Windows 7 64 Bit

RAM: 14 Gigabytes

HP PRODUCT LINK: https://support.hp.com/ca-en/document/c03832938

HARD DRIVE: Western Digital 1 Terabyte

As far as I am aware, only low profile graphics cards will fit in a small form factor PC.

Have you verified that is what the one you are looking at is low profile?

Have you checked  the candidate card's power requirements?

I can't do that for you since you have only provided the generic name for the video card without a model/manufacturer name.

[Kelly170]

For a fact, I know that it DOES NOT require a power cord, as it is a LOW PROFILE graphics card. It is manufactured by NVIDIA itself, not an off brand PNY or EVGA, etc.

By the way, thanks for the fast reply.

[Kelly170]

Edit: Actually, I looked at the label and found out that it IS manufactured by PNY, still talking about the NVIDIA K620 card.

The card has a 41 W power requirement.

It is compatible with  Windows Vista up to Windows 8.1

This is an older generation PCI Express 2.0 x16 card, it came to market in 2014.

I recommend that you make sure that you get the Low Profile version.

The marketing information at PNY does not state that it is low profile, but I saw ads with the unit for sale that specify low profile.

I can verify that the card is a single-size low profile type. Just one more thing. I remember reading somewhere that my computer (HP EliteDesk 800 G1 SFF) has a legacy BIOS, but the GPU only supports UEFI. Can this be a problem?

[erico]

Yes. A big problem.

That would make it incompatible with the PC's legacy BIOS.

UEFI BIOS did not exist back in the Windows Vista, Windows 7 days. 

If I were you I would take a hard look at the information that stated that it is UEFI.

The PNY marketing information, which included specifications that  I provided  does not state that.

Update: I did some more research and available information seems to support its being a UEFI card.

I can see that as a problem. Although, in the URL link you provided to me in your previous reply, some sites state that the only problem will be that certain features of the card will not work, not the card itself. Also on the PNY website, it says it supports Windows 7 (in which I am running), but when Windows 7 was released, UEFI never even existed yet. I have probably made a mistake in that last paragraph, so in that case, is there any way to upgrade the legacy BIOS to a UEFI (I’ve tried to do this in the past on another computer, but failed miserably and now that motherboard needs a new BIOS)?

[erico]

Upgrading MBR to UEFI?

No. That is not an option.

The only reasonable way to have a UEFI BIOS is for the motherboard to have had it as part of its design.

Motherboards are stuck with the BIOS type they are designed with.

"(I’ve tried to do this in the past on another computer, but failed miserably and now that motherboard needs a new BIOS)?"

A new BIOS chip of the same type with an original ROM programmed into it might save that board. 

YOU might find this wiki a good read. It should bring you up to speed on UEFI BIOS.

[Kelly170]

OK.

I've read over the website you provided me, and as my last question, will the Graphics Card work WHATSOEVER (Don't need any special features, just need 1 display to work with the card)?
