Or Im just the unluckiest RX-470 owner in the world? I'm 99% is not the way I flashed the card. I used the latest ed of AtiFlash btw, flashed it inside windows. Cause everytime I flashed to the stock rom and the card boots up fine.
Are you cloning the timings from your own bios or from the OP? If you are using your own, did you patch your driver to allow unsigned bios to run? Cause it'll cause all sorts of funky if you don't.
But if all the above is right, you may just not be able to use pure 1750 timings. Best thing to do, is clone your 1750 timings to the upper frequency, and set your memory speed in the bios to 1750, meaning the card can def use that frequency / timings as it is designed to do so. From there, via software, play with memory speeds. Unless you know 100% that you can work with 1750 @ 2000mhz, it's always recommended to put the timings you are using as your stock speed, and overclock via software. Once you find your limit, then flash it in bios.
Edit: Just noticed it's a 470, and the model you have has 7000mhz ram, so you'd see it as 1750 (any mod you do on memory is x4 to give the real value), so keep that in mind. I'm pretty sure the bios editor was built primarily with the 480 in mind, and just happens to work with the 470, and 460. I don't have one to tell you for sure how it is displayed unfortunately.Edited by jeb101 - 2/3/17 at 11:01am
