Hi everyone,
I went through a lot of threads and google searches, but though that it was wiser to ask here before doing it wrong.
The short version is: I purchased candidly one of those "4GB HD 7670 bla-bla.." cards on amazon, and installed it in an old computer just to give it a few more months/years of life. It worked, but goes artifact when memory is adressed a bit too high, because in reality it does not have 4 GB, but only 1, and BIOS is fake. So i'm looking for a compatible BIOS to flash into it (if possible) and see if I can recover it.
Long story:
The card was working ok, but of course as soon as memory requests were going a bit up, all was artefacting on screens, and I had to close programs to return to normal. Since beside a few seconds of latency and freezing the PC was responding well, I assumed it was mostly a matter of wrong settings, and after the aforementioned researches, I understood that the card itself was not really what they advertised. The seller told me he couldn't help me to make it right, refunded me and told me that I could just keep it; so before throwing it away I decided to take the challenge and see if it could be recovered somehow. And if it doesn't, no big loss.
First of all, some data about the card (I won't bother with the vendor's description since it's all a fluke, here is what I can make out of the card itself) :
Processor is a TURKS PRO, which should be able to run somewhere between 600-800 MHz;
Memory is composed by 4 SAMSUNG modules each of 2048 Mb for a grand total of 1024 MB aka 1 GB which are supposed (if i'm reading right) to be able to run at 1000 MHz;
Installed BIOS is a sort of rip-off from a Sapphire card that apparently was modified to run from DDR3 to DDR5; here I made a silly mistake and did not take a screenshot of GPU-Z before removing and disassembling the card, but if anyone can dig into the ROM image, I did save that.
The card was running at 650 MHz processor and 900 MHz memory.
Bios information looked similar to this
Except that BIOS version ended in 045 instead of 041, like here:
In any case, all these are fake, since they are addressing a phantomatic 4 GB memory.
I do know it's some pretty old and crap stuff, but since it seemed to be able to outrun the HD 6450 installed in that system (that is working flawlessly with this latter, but slow nowadays), I was hoping to give it a go at least for learning purposes.
Would anyone be able to help me finding a right ROM? (or driving me through to modify the existing one?)
I have seen a few on the ROMS database, but none seem to fit at 100% (wrong clocks, wrong processor, wrong memory provider etc..), so I need to at least know what to take into account and what can be discarded when choosing one.
Note that I do not know if the card can actually be flashed. I haven't seen anything that looks like unsoldered, so I'd expect that it can but still.
Thanks to anyone that may want to give a hand!
