Hey guys,
I have over the past weeks had issues when flashing my 7970's.
I have made a few mistakes, and learnt from them, but it seems like i may be making yet another one.
When I flash my cards, and i flashing from the Stock bios ( Sapphire 7970 Vapor-X 6Gb) to the Toxic Boost version (Sapphire 7970 Toxic 6Gb)
The new bios runs 1200/1600, instead of the 1050/1500. Unsure if volts are changed? I got to here one night late, trying out a few settings to mine, but nothing helped, but the cards ran great with the toxic bios.
Now, at first running the toxic bios wasnt an issue. All gaming was good, no issues anywhere.
One day i started to have a few issues in BF4, wether this is down to the game or my cards, or the screen, or (as highly suspect) the miniDP to DVI i cannot be sure.
But when moving fast, i was getting a cutting of a sort in the graphics, similar to when refresh rate is too low.
I headed out, disabled CFX, and flashed both cards back to stock 1050/1500 bios. This was fine, until, i turned on CFX. Turning it back on, would cause BSOD.
I tried to uninstall the 13.9 drivers, that caused BSOD.
I tried to update to the 14.4, that caused BSOD.
Then i did a system restore, to before i flashed my cards back to stock bios.
The system booted, both cards (of course) ran the stock bios, and they were running fine in CFX.
I went back into BF4, same issue, and it just annoyed my eyes to look at. With 2x 7970's i dont see how or why i should be getting such graphical issues when playing 1920x1200.
I left it alone, and didnt play much again.
Few days later, i re flashed to the toxic bios. Same story, disable CFX, flash and then try to enable CFX.
Same deal, BSOD, i thought, ok, i'll do a system restore. Worked fine, toxic bios, and back in CFX.
Last night, i got my third 7970 card for tri-fire.
Installed it, and wham, BSOD, from the get go.
I thought, **** it, and did a full system format and reinstall, as i had come to the conclusion that it was something in the system reg, messing it all up.
I formatted, installed chipset drivers, and then 14.4 driver. System booted, and i jumped into CCC to enable CFX on my newly installed system.
BSOD.
This was with 2x cards running Toxic and last card running stock bios.
Now, i got kinda annoyed. I ripped out the CFX bridges, flashed the cards, uninstalled 14.4, installed 13,9 drivers, system booted with 1920x1200 for once, and all 3 cards showed up in GPU-z with correct stock bios settings.
I turned off, hooked up the CFX bridges, booted up, and held my breath.
Booted into windows fine! Then i went into CCC, enable CFX, once more held my breath as i clicked ok. Flsahing of the screen's and to my amazment, i had tri-fire with no BSOD.
I ran a few benchings and all seems to work like it should.
Now, to my original question.
Can it really be true that i need to remove the CFX bridges when flashing my cards, or do i have a much much deeper issue?
