Now reflash using " atiflash -f -p biosname.rom" with your powercolor bios you should get yourĪt the end of each flash. NOW using " atiflash -f -p 0 empty.rom " flash the empty rom to the card DO NOT REBOOT AT THE COMPLEATION OF THE FLASH REBOOTING WILL KILL THE CARD FOR SURE!! Boot for your usb sitx with your good card into Dos using the "-ia 0 " switch confirm your card location. Reinstall your 'dead' card to slot 1 '0' of your motherboard.
#PROCEDURES FOR INSTALLING ATI RADEON 5870 IN MAC PRO DRIVERS#
Now remove the 'dead' card from the rig & boot to windowS from your working card uninstall your ati drivers I like to use DDU info & download using the 'clean& shutdown' option. You already have your usb dos boot stix with atiflash, the powercolor bios on it you need to add the empty.rom found in this post unzip it to your boot usb. To fix this we need to erase the chip totally. For some reason Atiflash decides not to write some Bits even thought it confirmsĪs a result you end up with an eeprom bios that almost works note memory size \ bandwidth \ Gpu clock \memory clk in post # 10. Let's fix this card!! As you've learned Atiflash has some issues with reprograming the onboard eeprom of the cards. PS : I'm not fluent in english and I hope that you were not hurt by the exotic expressions contained in my message.
I don't know why my card is automaticly "shuting down", do you have any idea to fix this ? So, as you can imagine, it's a "time trial" between me and the machine before the ninja HD4870 fades away. My computer needs something like one minute from POST message to open Windows 7. When i reboot to complete vbios update, the GPU fan's still runing like Usain Bolt and vbios cannot be fully updated (i guess). New Product Name: RV770XT 1GB 86A21CCA.QGH Old Product Name: RV770XT 1GB 86A21CCA.QGH ATIFLASH v4.17 Log File -Ĭommand Operation without options: -p 1 RV770.rom works fine while the "dead HD4870" is still "alive" and i did it several time. wtf is this ? The "ninja HD4870" ! XDĪnyway, the atiflash -f -p x. After reboot, windows does NOT recognize my " dead HD4870", same goes for atiwinflash and GPU-z.Ģ) There is some kind of "pattern" when i boot with "dead HD4870" plugged + DOS startup disk (" this is my design" as Will Graham says ^^) : I noticed that, after the GPU fan goes crazy, my HD4870 has 25 seconds "to live".Ġ0:18 > DOS prompt appears (atiflash can see/flash the presumed to be "dead" HD48710, it works)Ġ0:50 > GPU fan speeds up suddenly to 100% but atiflash can still see " dead HD4870"Ġ1:18 > atiflash -i gives me "adapter not found" ! With or without wiring the 1-8 pins, HD48710 is gone. Then, I can flash it with atiflash -f -p RV770.rom (only if I remove the cable between pin 1 and 8, of course ^^). This is true with or without wiring the 1-8 pins on bios chip. things are quite different for me than other "flash fail" cases :ġ) When I boot with a DOS startup disk in DOS mode, my "dead HD4870" is found by atiflash -i. neither wiring the pin 1 to pin 8 on Pm25LV010 chip as it is explained in this thread : Accidentally flashed my 5870 with a modified 6950 BIOS.recovery possible?īut. Then, I went to a store, bought a low-cost pcie card and followed procedures to recover my "dead HD4870". I did a backup of the original bios with GPU-z (RV770.rom), flashed my card with the 1083.bin file gave by Fastmix (atiflash -f -p 0 1083.bin) and taste my pleasure to have a black screen after reboot. I wasn't sure about what is a " reference video card" but I thought mine was. Click to expand.I read it and decided to flash my vbios.
