Polaris Bios Editing ( RX5xx / RX4xx ) - Page 75

post #741 of 3450
Hi i've a Shappire RX 480 Nitro+ OC 8GB (BIos duimp: ShappireRX480NitroOC8GB.zip 108k .zip file ) I'd like to try the mem timings mod, 1650 timings on 2000 strap. Should I use the timings provided from the 1st post?

These are my stock timings (1625/ 1750 / 2000):
  • 1625 ||| 555000000000000022CC1C00CE616C47D0570F15B48C250B006AE7000B031420FA8900A003000000190F2F39B22D3517
  • 1750 ||| 777000000000000022CC1C00106A6D4DD0571016B90D060C006AE70014051420FA8900A0030000001B11333DC0303A17
  • 2000 ||| 777000000000000022CC1C0031F67E57F05711183FCFB60D006C070124081420FA8900A0030000001E123A46DB354019

as you see my 1625 and 1750 straps are a bit different from the one provided in the 1st post:
  • 1625 ||| 777000000000000022CC1C00CE616C47D0570F15B48C250B006AE7000B031420FA8900A0030000001E123A46DB354019
  • 1750 ||| 777000000000000022CC1C00106A6D4DD0571016B90D060C006AE70014051420FA8900A0030000001E123A46DB354019

What timings should I use (mine or from the 1st post)? If I put the 1625 timings on the 2000 strap, should also copy them in the 1750?

My card has a dual bios switch, if bad flash happen, to recover my card can I:
  • Turn off PC
  • Switch to the working bios
  • Turn on PC
  • Boot to DOS boot-able USB
  • Switch to the bad bios (while the PC is still on, waiting for inputs)
  • AtiFlash.... balsh blah blah... restore my old dump
  • Turn off PC
  • Be happy cuz my card work again?

My timings are a mix of 1625 and 2000 or 1750/2000. Pure 1625 o 1750 are tighter....So use:
  1. 1625 ||| 555000000000000022CC1C00CE616C47D0570F15B48C250B006AE7000B031420FA8900A003000000190F2F39B22D3517
  2. 1750 ||| 777000000000000022CC1C00106A6D4DD0571016B90D060C006AE70014051420FA8900A0030000001B11333DC0303A17


Just put the "timing set" you prefer in the 2000Mhz strap and flash wink.gif

Ty for the fast reply biggrin.gif just some other questions. How did you come with these values? I see that you mixed some from my 2000 strap and some from my 1625, but how? Is there some guide? Each byte (or group of them) means something (of course) like tREFI, CAS, and all (or some of) the values from the common desktop RAM (I think), is there a way to know what byte does what?

Any clue about the bios recovery process with a dual bios card?

Not saying that's what's happening, but if true that would mean EMBD would have the same problem and ASUS Tweak and the same when using a reg file.
I had some strange permance loss.. firestrike benchmark at high clocks, and the result was only a few points more than at stock; tomb raider benchmark also had less fps. However, Afterburner showed no drops in voltage or clock rate, but the Performance was nearly stock. After a reboot, everything was fine again, until it wasn't. I didn't looked any further into it, but it really seems that there is a problem.

I am just wondering why AMD would do that, that's not exactly full control. Even nvidia wouldn't complain about shunt mods or bios-flashing.. why is AMD, who wanted to start a rebellion, doing this? And they should know by now, that there is a signed asus bios with 225W for ref cards out there.. maybe i really have to use that one.

edit:
ok.. had 500 points less than usual, without any mod.. reboot still fixes it. maybe some other issue, i don't care right now, but i'll keep an eye..

Say a checksum is not correct on rom, you share this rom, someone downloads it, a corruption happens from download/some system error on pc, member force flashes it = borked card/hassle to unbrick.

On this thread user Sony87 posted working Elipda Ram BIOS, flashed it and its pretty awersome but he used high voltage offsets, can someone bring them to "default" values (about -50 mV) or remove hard implemendation of voltage offset from value 4 to 0?

Ofcourse i can, but, after restart (and windows 10 restarts soo often) these settings won't previal.. and when im not in home to set them back there is big difference in power consumption. Now its 800 W for 170 MH in dual mode with mine settings. It takes about 980 W from Wall with maximum -96 mV that i can set in MSI afterburner (and this is applied after any restart) Without it its about 1150+ W. Have 6x rx 470 4 GB
