Polaris Bios Editing ( RX5xx / RX4xx ) - Page 104

post #1031 of 3408
That's fine, Firestrike and Ungine Heaven, both generate issues, but I do agree that firestrike (and time spy) generate more. You start seeing issues when you generate 1k+ errors every few seconds.

If I clock my ram at 2275-2300, I can pass a firestrike, but will have 4-5 million errors, and will have a low low score as memory latency is through the roof as it needs to reprocess that info 2-3 times.

How far can the power limit and current limit safely be unlocked on a reference board? I have the power limit set to 200w and the current set to 160a and I'm still hitting power throttling with an undervolt.




Here are some readings from hwinfo. Only thing I've changed during said readings was went from fire strike to unigine valley, and I dropped back to 1266mhz to see how it effected. The bios edits are the 1625/2000mhz timings in the OP here, as well as 1v for 1300mhz in the bios. My power limit changes are 110w TDP (same as stock), 160a TDC, 200w power limit. I am using wattool to set the power limit another 50% just to prevent throttling.

Okay, so things get weirder. Apparently my shipping bios shows different readings at the same setup.
154a max spike compared to ~200a on the rx480 unlocked bios, as well as an AMD bios from techpowerup, and a XFX bios from techpowerup.

Hi, anyone hitting 2Ghz on the rx 460? I can only see it as impressive, packing 32 gigapixel/s on just 16 Rops. That would be amazing.

i just read through this thread and saw you guys also bricked your rx 480 but fixed it.

To make it short: I bricked my rx 480 reference with the unlocked bios from der8auer and ati flash (command line) on windows 10. I was now able to reflash with help of the paperclip method (bridging the bios chip) the original bios from powertech as well as a the unlocked bios from der8auer. Windows is booting now and the rx 480 is recognized in the device manager, but after some seconds windows always freezes.

Any solution here?

Thanks in advance!

If i completely delete all drivers by DDU, windows boots up with those microsoft basic display drivers, but with a conflict. Ss soon i install the rx 480 driver, windows is freezing after 20% of installation.

For all that stuff im using the internal GPU of my mainboard.

Do you guys, or anyone else, know about any solution here?

Thanks in advance!

RX 480 draws only 90W~100W.... is it possible?

With a good card kept cool, I don't see why not. Heaven isn't the most stressful test either. With a good undervolt most cards should get pretty close to that efficiency.

Does anyone knows how to modify the voltage offset? That thing that you can set in WattTool

In Polaris Bios Editor, what exactly is the difference between "TDP" and "Max Power Limit"?

Hi, I'm running xfx rx 460 4gb double dissipation. I once saw 1.294v on the core, yet lately if I change 65288 it doesn't result in higher voltage. It pretty doesn't go any higher than stock voltage of 1.150v. I'm only up to 1300-1313mhz on 1.15v @ 90 watts even know it uses like 45 watts haha.

Might someone look at this bios and see why it won't show higher volts in gpuz/ hwinfo? I would mind rolling up to 1438mhz or 1536mhz... It runs really good for the low tdp. Totally 4k capable card at lower details. Older games no problem on ultra, just 40 to 60 watts.

I flashed the Sapphire Nitro RX460 bios, appears to be a 1.150v limit on all bios, up to 1313mhz max barely and 1300mhz is more stable. Though 1875mhz on the ram from 1750mhz : 112GB/s to 120GB/s on 1000mv isn't bad.

Can we remove the 1.150v limit? I added heatsinks to the core/ memory regulators among a few thousandths (increases core diode to heatsink pressure by a couple badly needed inch pounds) shaved off the heatsink mounting pegs. Used new screws without a thread-stop for max pressure and tightness which reduced core temps by 30C and regulators by 30C. Giving a bit of overhead.
