Polaris Bios Editing ( RX5xx / RX4xx ) - Page 113

post #1121 of 3404
So since custom bios are dead without mods (don't want to mod driver kernels), are there any reference compatible bios that have a higher power limit? I'm running a visiontek reference card and 50% power limit just

Go here there are quite a few with 140w tdp and some with 50 instead. Open them up in Polaris boos editor to check

I know some have higher TDP but they have to be reference compatible or it could fry my card (alien VRMs).

Isnt this one a modified reference bios and signed (somehow) so it wouldnt conflict with the drivers ? http://overclocking.guide/download/amd-radeon-rx-480-unlocked-air-bios/

no idea short of testing but last I tried it, it doesn't work right with my card =\

I've added the BIOS signature check to the pixel clock patcher: https://www.monitortests.com/forum/Thread-AMD-ATI-Pixel-Clock-Patcher

1. Install the driver normally. Do not reboot when asked.
2. Run atikmdag-patcher.exe to patch the driver.
3. Reboot.

I haven't tested it with a modified BIOS, so let me know if it works. You can undo the patch by running the patcher again. If you don't need any of the pixel clock limits, you can rename the file to atikmdag-patcher-bios.exe to patch only the BIOS signature check.

Amazing! - I have Windows 10 64 bits, two RX 480 with my custom bios and water, today install the last beta driver, apply the patch, reboot, and works perfect

For anyone who doesn't wanna patch, it appears 16.9.2 works fine with any bios from my testing. I'm testing the 16.9.2 driver on 16.12.2 relive to see if you keep the relive on a driver that doesn't need patching...

*Update* works fine on 16.9.2 no need to patch anything and I just device manager'ed the 16.9.2 driver on top of 16.12.2 and all is fine on modded bios... kind of easier.. so maybe we can find out what it is about 16.9.2 that works fine without the need to patch... I don't know if ReLive is picky but it doesn't work on 16.9.2... so I suppose 16.9.2 would be fine if you don't care about ReLive.. for the moment at least until the new drivers reflect whatever it is that makes 16.9.2 special.

IIRC 16.11.5 should work as well with modded bioses.

From ~16.9.1 to 16.11.5 amd disabled the bios check, with the new drivers they simply enabled it again.

The first driver that supported polaris, didn't had the bios check, they later introduced it (around 16.7.something) and disabled it on 16.9.1 untill the new 16.12.1 (ReLive app has nothing to do with the bios check, is related to kernel)

Nice, thanks. I didn't know 16.11.5 worked too. However I find the WHQL Certified 16.9.2 to work beautifully. After finding they have unlocked xfx BIOS, I run the 2000Mhz memory timing strap on 1875Mhz (120GB/s vs 112GB/s) totally stable. I wish there was a strap for 2125Mhz timing strap so I can apply the higher timings to the 2000Mhz speed for 128GB/s. With default timing strap at 1875Mhz it is not stable and crashes eventually, running 1625mhz/1750mhz timing on the 1875mhz strap is even less stable. It is totally stable and 100% glitch free with 2000mhz strap @ 1875mhz and completely stable on modded unlocked bios. I run it up to 1282Mhz core which is 20.5Gpixel & 82.0Gtexel on 65288... We can't increase voltage in the bios, is that going to be forever? Also can someone come up with a higher timing scheme for the RX 460 strap so I can use further relaxed timings to clock the RX 460 @ 128GB/s?

I run 2000Mhz timing strap @ 1875Mhz because 2000Mhz timings here is not stable @ 2000Mhz... Need further relaxed timings for continuous stability.

1875mhz
999000000000000022AA1C00D6727E4BC0551218C30FE70C006B0601150A1420EA89C0AB030000001D172F35CE344418
2000mhz
999000000000000022AA1C00F7F67E4FD0551319C650B70D006C06011D0C1420EA8980AC030000001E183238DB364719

This is the rig I'm running the RX 460 in with a 3166Mhz Quad-Core Xeon, 8GB Ram, Marvell HyperDuo and it can do a bit of 4k and primarily runs perfect at 1440p. The RX 460 is a card you really should appreciate, to sit back and realize it uses less than a light bulb and does an amazing job to handle 4k and really smooth 1440p. I may fiddle with higher tdp because that's what controls fps @ high resolutions... Higher tdp means smoother 4k, lower tdp means way laggier.




1984Mhz @ 127.00GB/s is possible @ 2000Mhz timing strap stable (Copy 2000mhz strap to 1875mhz) & 127.50GB/s is possible @ 1992Mhz (Probably not likely) take your GB per second X 15.625 = Memory clock : 127.50 X 15.625 = 1992



Further testing proves 1297Mhz core & 1992Mhz memory to work fine. However both voltage & power is software/hardware-ish limited. Only a reset of trixx increases power limit. Here's some comparisons and I had initial at 64 watts, max power at 88 watts, and ampere at 66 amperes(which did not take). It's limited to 50 watts roughly. So it's clear that it's not that the RX 460 is "Weak" it's that it's limited is all... It's certainly capable of a 30fps experience @ 4k with a limit increase from 50 to say 64 watts (Through wherever the limit is within the bios/ driver/ software).

Well, It appears I have done it.
Because of engineering provisioning principle thermal properties of the voltage regulators, the card is limited by "hardware" so-to-speak... Thermally only. It's fine though. It appears as with any and all AMD GPU Hardware they have unforeseen hidden overhead and capabilities that for some reason AMD overlooked. It's all a mathematical formula of ratios between the total allowable power delivery limitations and which of these components are the rulers of pulling higher frames per second. So it has become so perfectly clear that clocking the video memory way out is beyond pointless, it's just a buffer. The visual data is just stored in the video buffer and requires an initial buffer rate that keeps hitching to a minimum. Like system memory, faster system memory is only better at reducing hitching. In terms of the graphics processing unit, it just needs "Enough Buffer Rate To Get Er' Done" and then hand over all the grueling tasks to the mighty GPU Core Diode. So in short in comes down to the delicate nature of the memory clock, memory voltage, and memory timing to give the proper amount of overhead back to the GPU Core Diode to Get Er' Done. I'm still working out the kinks as for what specific memory voltage, clock, and timing yields continuous stability. So far it appears that one Memory Timing Strap above the given clock is generally the most stable. I have yet to test 2 memory strap timing hops for a given voltage to yield greater stability. So far I am just in Aw of the performance I am now achieving @ 3840x2160.

Maybe it was the Frame Rate Limiter... I am not sure but I notice 1500mhz on 1250mhz timing strap is the fastest.. still need to compare but it only shows through on 4k or when it just sits at 20fps... with reducing the memory staying within its thermal allowance of 50 watts it does around 30fps @ 4k on unreal engine 3. Way better and this card was never meant to do this... if it could be done, i say why not?
