Unsual Radeon HD 7570 with 4GB GDDR5

A friend of mine had given me his old PC, sans hard drives, and interestingly the GPU in there was an unbranded Radeon HD 7570, but labeled as 4GB GDDR5.

I had set down to research this, and astoundingly, it is a Radeon HD 7570, and it actually has 4GB of GDDR5 (4x1GB@750Mhz, i.e., 3000Mhz, manufactured by Hynix), and additionally, it also appears properly in Linux (working as well as any pre-GCN card from the HD 7000 series), with no tricks whatsoever.

The cooler is obviously very low quality, but it seems to be alright for now (especially with the Arctic Silver 5 treatment).

Funnily, it appears that this card is compatible with higher quality coolers for low- to midrange cards from known brands.

 

The funny thing is, that it does not even appear in AMD's internal database, from what I had understood speaking with an AMD representative.

 

I had tried sending AMD my findings, but for some odd reason my emails never get through, due to my address being "blocked" from sending messages to the address I was given, so I am posting them here, and when I'll have time, I'll notify AMD about this.

 

The GLXinfo output has been uploaded to here, while the 7z archive containing the pictures (both original and labeled) of the board will be uploaded to Firefox Send when I have the time (~134.1MB, and I currently have very bad connectivity).

I will upload a few pictures, though, ahead of the rest.

that's what OEMs did to extend old GPU's lifespan. I remember Dell making a 2GB GDDR5 variant for this originally 1GB GDDR3 card

I haven't had the time to check on Windows, @LukeSavenije, since my primary OS is Linux (Solus, to be precise).

However, it appears to be legitimate, based off the chip models.

That is why I had called AMD, so that they could take a look at their internal database, but nothing came up.

The hynix memory chips are h5gq2h24mfr (or afr at end, same thing) , which are 2 gbit chips. T2 in T2C tells you they are rated for 2.5 Ghz (so since it's GDDR5 that means it's double, so "5 Ghz")

 

See https://www.skhynix.com/eolproducts.view.do?pronm=GDDR5+SDRAM&srnm=H5GQ2H24MFR&rk=26&rc=graphics

 

You have 4 chips on the card, which means the memory bus is 128 bit wide (since each memory chip is 32 bit wide), and it means the total memory is 4 x 2 gbit = 8 gbit = 1 GB GDDR5

 

So no, you don't have 4 GB, you have 1 GB of GDDR5.

 

216-0810001 seems to be the code for AMD HD 6770 die, so you probably have a fake card, with a modified bios.

Note that HD 6770 was a rebadge/rename of HD 5770 / HD 5750 so maaaybe just maybe they screwed the label and said 7570 instead of 5750 but I sincerely doubt it.

Thanks, I'll have to do some more research, since it would appear that I have read things wrong (and have much to learn).

This may be a good time to try modding the firmware to show the correct data.

 

By the way, @mariushm I may be close to contacting someone who can supply me some silver.

Last week i purchased another 4GB HD7570.... 4GB 128-bit card for $15! it's a no brainer!
Looks like the same card as moriel's, but this one has Samsung memory and a different cooler.

Installs fine - runs Windows 7 without any problems...even furmark is OK. However once >1GB video is used computer either reboots or blue screens.

CPUZ info is also correct.

Yeah, they're 2 gbps chips (so 4 x 2 = 8 gbps = 1 GB) rated for 6 gbps (1250 Mhz x 4 or a lower value like 1150 mhz, memory may have run at lower frequency than memory chip maximum frequency) .... see datasheet if interested: https://datasheet.ciiva.com/26785/k4g20325fc-hc04-26785647.pdf

 

You may be able to flash it with a bios from a 1GB card, as long as you get the chip right and the bios has "straps" for those samsung chips. 

 

Techpowerup has lots of bioses here (filtered to show only cards with 1GB GDDR5) : https://www.techpowerup.com/vgabios/?architecture=&manufacturer=&model=&version=&interface=&memType=GDDR5&memSize=1024&since=

 

I would look at HD 6770 bioses since that's what 216-0810001 seems to refer to... techpowerup has 77 of them 

 

 

You can probably use ATi Winflash to change the bios on the cards...

mariushm... thanks for the info. This card was purchased from ebay - so i will just use 'buyer protection' and return it. 

Probably can be flashed back...just getting the correct BIOS, it's time consuming....and just a HD6770 after all the effort.

Good info on the memory - thanks again.

Alright, with a little help from Luc Verhaegen (one of the main SUSE developers working on open-source ATI graphics, back in the day), I had backed up the firmware from my fake "HD5750" using FlashROM, where interestingly enough, in the first few lines it claims to have only 1 GB of GDDR5 RAM (the "4GB" is probably elsewhere in the firmware, as what the GPU presents the OS with).

 

I do not know how to read the firmware any better than I already have (even with AtomDis), however this is already a start.

 

@KE1TH, can you please backup up your GPU's firmware and send me a copy?

I personally would prefer a firmware that is optimized to these cards (preferably an open-source one), to one that is meant for another GPU, and comparing both of these firmwares may help with that (as well as potentially opening the gate for an open-source firmware for them).

By the way, from your picture it looks that the cooler is precisely the same as mine.

My card reports to the OS that the maximum VRAM frequency is 750Mhz, which may be something to ponder.

It's been quite a while, however a (possibly final) update:

My card has become defective, with the card no longer properly recognizing monitors (and keeping the maximum resolution at 1280x768p), and DVI not working at all anymore.

 

Note, my motherboard may have also become defective, since I am having RTC issues, which no amounts of firmware resets or reflashes (even via recovery flashing) change, so I do not think that the GPU is the cause (it may, but I do not think so).

 

So for the time being, I am back on iGPU, and temporarily, also a different motherboard (MSI H61M-P31/W8, with an i3-3220).
