My Sapphire 4870 1GB was working fine. I want to push it a little more and flash the Bios to the Toxic one at 780/1000 last night. I use atiflash at dos to flash it, and everything was good. Reboot and tested with 3Dmark Vantage, and found a lot of artifact. I canceled the run, and flash back the original Bios. I reboot the computer, but no beep, no display, just blank screen. The strange thing is, if I put the card in the 2nd pci-e slot, and use another ati card at the 1st pci-e, I can enter Windows normally, and the computer hardware shows the 4800 card working normally. Also all the light on the back of the 4870 card shows everything normal.

I flash the bios using: atiflash -p -i 0 biosname.bin
Bios is from: http://www.techpowerup.com/vga...0&interface=&memSize=0

Can anyone help?



RMA fraud is not an appropriate topic of discussion here.

Neither did I. Why would you do a bios flash when you can increase clocks with programs like Riva Tuner!? I understand bios flashing when you want to increase the gpu voltage, but just to increase clocks, is silly.

For OP, just try flashing the "stock" bios again. Maybe there was something wrong when you did it the first time.

I had already try all the 1gb Sapphire 4870 bios from techpowerup database. I even tried other brand 750/900 4870 1gb bios. All flash complete and success, then reboot. Some bios gave me blank screen, no boot. Some bios can boot to windows, but with scramble pixels.

I flashed my other Visiontek 4850 512mb and ATI 4870 1gb to other brand bios without any problem. I don't know why it does not work for the Sapphire. Here is the one I have: http://www.newegg.com/Product/...x?Item=N82E16814102801

I will RMA and get a new one.

Some people feel a certain bios are special allowing for higher clocks, which is just not the case. Either way I agree with applications like ATi Tray Tools you don't need to edit the bios.

Regarding reflashing, did you not read the link I post? The OP more that likely doesn't have a proper copy of the original bios, depending on how he saved it, so reflashing with the same bad copy will do nothing to fix the problem.

Sapphire may accept your RMA, they're pretty cool, but after you flashed your bios with non standard bios, you voided your warranty. :eek:

I flash the card back to the original Bios. They never know what I had done. Checked the review on newegg on this card, there are many DOA and many defective after a few weeks. I think the quality from Sapphire is not that great either.

Reasons to flash Bios:
1. Fix the fan speed
2. Overclock without loading the ATItool or rivatuner
3. Most importantly. Get the crossfire working. When you insert 2 ATI 4850, and try to crossfire, but these is no tab for Xfire in the CCC. What you can do? I flash my 4850 to other brand, and restart. Yahoo, the magic Xfire tab come out. Search on google, you see many people get frustrate when they try to Xfire, but no Xfire tab.

Its tools like you that affect everyone's pricing.


It isn't Sapphires problem that you feel you need to flash your BIOS to OC a graphics card.

1 and 2 are doable with ATi tray tools. What is so hard and unconfortable to use that to load with windows? Every time you turn on your computer the card is overclocked and the fan speed is set as you put it.
I don't know about the third, but it's clearly that this crossfire issue has nothing to do with your current card.

I actually flashed a 4870 512 mb Sapphire card's bios, but that was because of the common bug that the first blue PCB batch of cards had. It wasn't usable without the flash in some particular games.
Increasing gpu voltage or fixing a known bug are the only reasons to flash a card's bios. But your card has the volterra chip, so vgpu can be increased through software and you hadn't experienced any bugs, so the reason to flash isn't there.

Saphire sucks. We once bought a batch of 40 Saphire HD3870's, and out of 40, 4 of them were dead, and 5-6 had old bios that I had to flashed because otherwise the fans would keep spinning at 0% or 100% exclusively.
So RMA your Saphire without conscience.
