These cards look identical! Could it be possible to flash a GTX 570 to a GTX 580? Notice the GTX 570 even has marks for an 8 pin power connector, it's just not there. Could it also have the 384 bit memory bus, just running a BIOS that only uses 320 bits?
If so, I better order one quick before they sell out...
Then why do they have the same number of memory chips, even though they have different amounts of memory? They could easily be the same card with the same GPU - only a different BIOS and power connector.
The difference isn't only the BIOS and power connectors,like I said,they have different stream processors.There is no way to unlock them.
There are many cards that have pretty much the same specs but different stream processors, and you can't flash them either.
Some of the GTX465s are flashable to GTX470s even though they have a different number of stream processors. They have a different memory bus width as well - the GTX 465 has a 256 bit wide bus and the GTX 470 a 320 bit bus.
I've run a GTS250 BIOS on an 8800GT just fine - and that isn't even on the same transistor lithography.
I just thought maybe someone had noticed the physical similarities between the boards and tried this flash.
Maybe I should have posted in the overclocking section...
it's for marketing and profit. AMD HD 6950/6970 does exactly same. 99.9% of current market 6950 is flashable to 6970 without error. Though I'm not sure about 570/580..so don't risk it before someone tried it successfully.
Your options are to:
A) Buy a GTX 580
B) Buy a GTX 560 Ti, and resodder on the missing parts, and hope Nvidia didnt plan on someone doing that... chances are the board will have empty traces that are ment for the 8pin connector so wouldnt work anyway. I give it a 5% chance of working.
I doent know about the PNY but the EVGA GTX 570 Classified is a GTX 580 in everyway except the GPU in the middle heatsinks and PCB are the same it even has one six pin and one eight pin power connectors. The water block fits the bcking plate fits if your going to have any luck that is that card to use.
