Polaris Bios Editing ( RX5xx / RX4xx ) - Page 172

post #1711 of 3413
Just for fun try this haha by the way good morning

I made this fresh from stock bios for a nearer to stock checksum... rather than modding on top of a previous .rom

Instability is from too high Max Temp/ Hot Spot... needs to be in the sweet spot... Likely 84C.

OK I'll give them a whirl. So no timing changes here right? After that mess yesterday I don't want to deal with that again and consider myself fortunate I was able to get a bios back on that one card. Thanks.

Yeah man it's stock timings 1000mv. I hear ya, timings are a fine tuning procedure.

For instance you can gain a lot from CL call it to 15, to CL 16. That's a lot more time which is good for stability. It's all about giving the gpu core "brain" a little more time to think about things before actually putting said data to work. Make sense? haha

Plus this means low timings means "Impatient" memory and high timings means "Patient" memory. If we give the Core CPU/GPU a little more time to think things over, the yield of compute will be of higher quality. Than if it were not to think about what it's working on long enough. HAHA

Hello all, I'm trying to modify my bios but PolarisBiosEditor_1.4 tells me that the size of my bios is under 512k and that I could brick my card. Is it true ?

Yep cards done bro, pitch it in the trash... Pick up a Voodoo haha wink.gif teasing

Upload your .rom in .zip here I'll check it out.

Yeah makes perfect sense I've fooled with the timings on motherboard ram like I run 8-8-8-24 I can run 7-7-7-21 and get better bench scores but not stable for long term use.

Here's results with top bios I got the frame drop in the second scene of the bench again but I think it might be a cpu core hitting 100% for a second then it straightens back out. FPS on this bios is amazing for the bench at 1080p ultra preset dx12 mgpu.





3D Mark Firestrike crashed on last combined test was killing it till then


Here's Deus Ex Bench 1080p ultra preset dx12 mgpu



Here's Valley Bench

I've flashed new bios but windows doesn't recognize my card, the problem is signature check ? How do I can fix ?
