Polaris Bios Editing ( RX5xx / RX4xx ) - Page 275

post #2741 of 3874
Generaleramon,

Tested your Uber v2.3 and Uber v3.0 straps on seven Sapphite Nitro+ RX 580 LEs. v2.3 performs great as expected, all but one card can clock to 2100mhz with it. With Uber 3.0, only one card can keep 2100mhz clock, and the rest perform worse than v2.3 at their max stable clock. So overall, v2.3 can be the better choice for some.

Need Help:
I have tested many Bios files from RX470/480/580 4GB and found that only Shapphire 570 Bios (NITRO/Pulse) gives me the best performance at same clock (~5-7%) but the IDLE power draw is very high~29W with 5K monitor 2XDP.
on other bios like GIgabyte/MSI i get under 7W on IDLE and under 100W in full Load (130W Avg with shappirre).
can you explain what causes it?

V3.0 has a low TRFC(probably the problem for you) and RAS2RAS. If v2.3 is better for your cards than stick with it. smile.gif

or try this

TRFC=140 (+5)
RAS2RAS=190 (+4)

-TRCDR and TRCDRA are now equal (GDDR5 standard?)
-TRFC set to 136 (+1) and RAS2RAS to 186 (+1) for a (very) little more stability
-TRP=27 but no performance penalty
-TCCDL=4 best for GDDR5?
-RASMACTRD=47 RASMACTWR=63 for better performance

Is there a guide/reference on how to mod supported memory chips inside bios file?
post #2746 of 3874
First of all, thank you for this fantastic thread. I was now for months a silent reader. But now I really need help of the community. I got 2 Problems.

I installed W10 and crimson 17.4.3. I do not manage to run both of my Cards. 1 XFX 480 GTR 8GB Samsung and 1 RX 470 Sapphire Nitro 8GB Samsung. Both with BIOS switch.

Windows will not load the amd Driver and loads win Standard Driver instead. This with modded BIOS.

If I remove one Card, set BIOS switch to stock rom, Win will load the driver. Switched to mod driver, win loads standard driver. So I used atikmdag patcher for my modded bios. After this, win loads modded card an amd driver. I remove the graphic card and repeat the steps with same positive result.

But if I add now both cards and start win, only the driver of the card which is connected to the screen, will load amd driver. The other card is appears in GPU-Z but only with 300Mhz and no driver. Mining works with 4Mhs. If I connect the screen to the other card, the result is the same.

If I uninstall AMD driver with the AMD clean uninstall utility and try another driver version, it doesn't work either.

I'm dam confused now. Atikmdag patcher seems to patch only one card. How do I have to work around to get it fine? I lost hours until now to find a way out.

Restore win10 to safety point and install 16.9.1 AMD driver? (if possible)
Use the atikmdag patcher differently?

Any reliable answers are very welcome.

thanks

i have experienced this using a sapphire 580 bios on my reference xfx 480. now with a gigabyte bios it's all back to normal. i think the vrms calibration and power/current reporting is different in some 5xxs and so you see a difference like @idle(7 vs 29w). if voltages/clocks are the same the power consumption can't increase 400%. idle temp will be also affected.

i can't test this now BUT:

if the bios support only one memory type, a simple copy-paste (hex editor) of the timings for your card should work ( remember to change the memID in the timings to 00). gpuz will report the wrong vram manufacturer but the timings will be right.

It doesnt work like that. I have tried changing the memory ID and the card wont POST.

Have you tried changing the vram name in the beginning of the vram_info block?
The vram_info tables have the same lenght?
Clearly the problem is in this section
