sweet thanks man. good instructions. do i need to bother with ddu or uninstalling the current 17.1.1 drivers i have installed before running the patcher?

@nikoli707 Sure thing man, Your welcome. When you flash and restart without doing anything with the drivers, what will happen is it'll say driver signature issue in device manager... you could patch in place i think... or just pass on 17.1.1 unless you love recording for the moment until whql drivers come out... I run my XFX 4GB RX 460 Unlocked same clocks as that bios I made for you on 16.9.2 as you just install easy-peazy, and it runs fine... I barely use it though... since I don't game at 1080p... 3840x2160 on my rx 460... it is playable at least so that's amazing on 50 watts... Unreal Engine 3 titles do fine at 4k on the rx 460. I haven't really tested many games on mine... since it's not very fast haha.. dont get me wrong best 50 watt video card but yeah anyway I love my 390x 8gb.

here's some 390x screenshots. Previous 10fps screens is I was screwing with the ini file and had lod scalar set to 10 trillion miles away to render everything... had to start over but fps is nice and looks beautiful. All of these shots are with undervolted 875 vddci ram at 320gb/s & 1133mhz core. I have now ran it up to 1188mhz/ 1563mhz (76gpixel/209gtexel/400gb/s) but limit to 30fps. Some of these are below 30fps because I was still fine-tuning ENB Shadow Boost... Had to get the distances and target fps just right... have to turn off the game's Ambient Occlusion to use ENB Ambient Occlusion, and must set shadow boost to 29fps target since game's target is 30fps & 60fps with built-in Cinematic-Presentation vSync.

Anyone knows how to edit the XFX RX 480 RS BIOS?

I want to unlock the powerlimit (20% is max.), voltage control (1.175V seems to be max..) and possibly increase the memory voltages. But so far any attempt to change any value has made the card 100% malfunction - Wattman complains there is no driver.

Also tried using other XFX BIOSes, but these are counting Power differently, so card thinks it gets powerstarved and downclocks to 700 Mhz at +50% power....

In the most recent Crimson drivers BIOS signature checking is enabled and custom BIOSes cannot be normally loaded. This can be circumvented (for now) by patching atikmdag.sys with the ATI pixel clock patcher available here here: https://www.monitortests.com/forum/Thread-AMD-ATI-Pixel-Clock-Patcher

Well managed to FU one of my bioses on my 480, thankfully my card has a dual bios. But how am i supposed to un**** my other bios?

Boot with switch on good BIOS; once booted toggle switch to bad BIOS, flash a backup.

I'm sitting over here with a 390x 8gb @ 1204Mhz on reference blower.. So amazing on air and quieter than before.. worked over the core vrm pads (secret?) and tuned the airflow. It's actually stable too of all things?!? I was expecting instability as usual but no... I think I could crank the ram out to 450GB/s if I get some fujipoly 17w/m k pads... just for safety... not trusting factory memory pads at mega clocks.

I'm wondering would an RX 480 8gb even @ 1563Mhz out run this?

I don't think 1563MHz on air is very realistic for RX480.

@Loladinas If I ever get my hands on an 8GB RX 480, i'll be on here continuous. It will be done. wink.gif

I'm not downing on Polaris 10 at all, I love all of AMD. I just would be thoroughly blown out of my socks if the RX 480 straight smokes my 390X. biggrin.gif

I'm on PCIe 2.0 so I'm not even seeing the true potential of this card, nor would I see the true potential of the RX480 again at PCIe 2.0... 5GT/s vs 8GT/s. I'm noticing around 10 to even 25 fps slower on PCIe 2.0 vs PCIe 3.0... The higher tech we go we are seeing greater losses @ PCIe 2.0.

PCIe 2.0 vs PCIe 3.0 is 5GT/s vs 8GT/s... That's 60% more throughput capacity... From 60fps to 96fps... That's a real thing you know. You gotta have very serious CPU processing power to utilize 8GT/s... Far beyond what any single CPU could, unless that single CPU was super-powerful... Like an Octa-Core with Octa-Logical-Threads per each one physical. Then we could actually withness the full 60% increase... No current-gen Hexa or Octa core or better could utilize the 8GT/s as of yet. We would need maybe dual 24 core/ 48 thread CPU's to feed the mega-PCIe-bus.
