Everything seems fine and I proceed to solder the AMD eeprom to the GTX 970m. I pop the AMD chip into my flasher and flash Prema's GTX 970m vbios to the AMD eeprom to it. At this point I have nothing to loose, so I unsolder a few of the AMD 6990m eeproms (AMD didn't stupidly put a thermal well under the eeproms). However, according to the datasheets, they seem to be pin compatible. I look at the eeprom's on those cards and compare them to the eeprom I took off of the GTX 970m. I have about 4 dead 6990m's lying around that all suffered from warped PCB breaking the solderjoints under the gpu itself. Why the **** would you put a thermal well under a eeprom chip? It doesn't get hot - it doesn't need cooling! As a result, the chip sinks so much heat, that it's nearly impossible to remove it without destroying it. It turns out NVIDIA put a thermal well underneath the eeprom chip. I finally get it off but the chip is destroyed. The only issue is the chip is sinking a TON of heat and it's very hard to get off. I take the GTX 970m out of the computer, and desolder the eeprom chip which stores the vbios. I put a 7970m back in the primary slot, and put the GTX 970m in the slave slot, upon booting, windows doesn't even detect the GTX 970m and nvflash is just as useless. Upon restarting, the computer won't post. I reinstall the GTX 970m, and flash it to a different vbios. Next I try putting my 7970m's back into the computer and guess what, still a black internal display. The flash was successful, but still a dead internal display. For some reason, after the flash windows stopped detecting the internal display.Īt this point I decide to flash back to the original vbios to try and fix the issue. I plug the computer into an external monitor via HDMI, and it works. The computer boots into windows fine, but the internal display is black. I flashed the card, restarted my computer, and all I get is a black screen. I decided to flash Prema's custom GTX 970m vbios which is supposed to take care of that issue. The only problem was the throttling due to the TDP limit imposed by the vbios.
I got the first card in the mail and installed it without any problems.
I recently bought two GTX 970m's to replace the 7970m CFX setup in my p-377sm-a.
