Sapphire/AMD HD6450 LP silent 1G DDR3 128kB ROM with UEFI support

[AugeK]

I managed to mod the BIOS of the card mentionned in headline to support UEFI, no more CSM required.

ALWAYS backup your genuine BIOS first!!!

Excellent! Now that's what I call initiative!

 

[AugeK]

Thanks!

My motivation was to make it suitable for Windows 11, which the Windows health check tool confirmes.

User @MrGenius used to do GOP updates to card bios, so your services would be good here

Thanks!

Open GPU-Z, click the arrow next to the Uefi checkbox and Upload the bios through GPU-Z to the VGA Bios Collection/Database, make sure your description has the SKU info mentioned from the sticker on the card.

Also a GPU-Z screenshot would be nice

 

[AugeK]

Didnt check the sticker, just had the Computer performing heaps of updates.
No problems yet but fully on your own risk.
GPU-Z confirmed UEFI.
Screenshots to follow.

Every bios flash is at the users risk, make sure to follow directions above, thanks.

Click the Black Arrow right of the uefi check box

Ask him if he would come here to do his work, we once in a blue moon need GOP updates on bios.

@Mussels testifies on this.

I found it, it is a very old bios as there are others from 2015 and 2017. If anything Id mod 1 2015 bios as the 2017 bios only have samsung ram.

Once one understood the advices, it is quite straight forward.

If you want me to I could do a few mods, but someone else would have to do the testing.
Just to figure out if it works...
The one above took me half a day, including restoring (had an additional card to resurrect this one) but I think I got it now.

Old, but funktional.
The only one available for Sapphire I thought.

Here is the result on 2015:

Appears to be stable
Find ROM in Database or use file attached

Also tried the 2015-09-30, big s..t!
Boots, but renders Windows desk useless.

Wait a sec,check the clock speeds

 

[AugeK]

Think so

 

[eidairaman1]

Think so

Actually you did a 9 30 bios, thec1 i provided is earlier than that lol

 

[AugeK]

From the list I wasn't sure which one was meant so I took those from 2015, both

From the GPU-Z screenshot it looks like the driver Windows 11 provides is very basic, no wonder, ATI VLIW-5 cards (up to HD 5870 and small 6xxx refreshes) have been unsupported for quite a while. The latest win10 driver is from 2016 - v16.2.1beta. Well as long as it is useful.

 

[AugeK]

For office applications, which is all my father-in-law does with his computer, the card will do.
No need to spend a fortune on over-powered gadgets.

Appears to be a driver problem..
After installing Catalyst 15.7 driver (must select manually) clock indication is ok:

Yeah i forgot usually after a bios flash it is Highly Recommended to reinstall drivers.

One question: Sapphire has sold a whole range of HD 6450 graphics cards, including various silent models. Is this BIOS version compatible with all of them? If not, how can I make sure I buy a compatible card? Thank you.

 

[Canned Noodles]

What are the benefits of a UEFI graphics card BIOS? Is it primarily for Windows 11 compatibility?

 

[AugeK]

Yes

No, they are not all the same, different skus, device id/subsystem ids, ram-type/brand/model.

The only way to know is to get gpu-z get a screenshot, then go to advanced tab and look for Memory Timings (change the word general). Also removing the heatsink and getting ram chip pics. With sapphire cards getting a sku/part number sticker puc.

 

[AugeK]

You can add UEFI support to such a card if memory size is 128 MB or above.
Bist follow the instructions linked above.

Thank you, but just to make sure I understand you correctly, even if the SKU number is identical, that alone is not a certainty that it is the correct card, but I would then have to check the other things you mentioned?

 

[AugeK]

Best way is to pull the BIOS from the grafics card, add UEFI support as described above and flash.
Male sure you have access to some other graphics card, just in case.
