Polaris Bios Editing ( RX5xx / RX4xx ) - Page 148

post #1471 of 3403
Thanks.I want to tight the timings on memory on bios and flash it for better results for mining Etherium. But i am with Micron memory and show me same problem, lines are with timings did't show me in mhz and i am not shure which lines must to change and actually can't find bios rom file for that memory... standart bios is http://dox.bg/files/dw?a=381d301461

@kckyle Hi, basically the 8gb models stock clocked on stock timings at 2000mhz memory. If you can run stable at stock volts 2000mhz memory with all 4gb totally taxed out to the max on Tomb Raider 4k ultra. Then you may have 4gb locked. Though the 4gb cards had slower memory and were not stable at 2000mhz memory on a continuous basis. Best way to compare it open bios Polaris Bios Editior and copy to notepad your 2000mhz memory timing string and compare to 8gb memory timing 2000mhz. If the modules and timings are different, it's a 4gb card and no more.

As far as timings go, there is no "best timing". Stock is best. Just don't clock the memory too high basically.

Around 220000MB/s allows me to reach 16k Firestrike Graphics, about 400 points more from generaleramon best mix. But I see a lot of texture corruption: http://www.3dmark.com/fs/11869882

Next week I will do further test and try 1625MHz strap.

Just a little nano comparison to my system. For encoding SMP and many/ most tasks SMP performs the fastest. Though this shows NUMA pulls way higher memory performance on this application and maybe some/ most possibly. I get even load on all 24 threads in SMP for encoding when NUMA only hits on some... so NUMA encodes slower by a lot but has way more memory bandwidth. Maybe I'll try NUMA for some games.

390X scores - PCIe 2.0 limitation here on my system, scores would be much higher on PCIe 3.0.

The very first test top left is 1.5Ghz per core locked down max power efficiency. Which still straight leaves my 4.8Ghz i7 in the dust on dual xeon's at 1.5Ghz. So funny. Paid literally 400 dollars for my T7500 and at 1.5Ghz the Xeon's only use 47.5 watts each/ total 95 watts. When the i7 would be using well over 200 watts. I'm trailing the 6950x on CPU-z multithread. Though the Ryzen R7 1700 straight smokes the dual xeon's on 65 flippin watts. haha The Ryzen R7 1700 is nothing short of Super-Computer performance without a shadow of a doubt. With the R7 1700 coupled with a Vega that doubles my 390x scores if possible? It will be insane.



Looks like possibly the 390x delimited at 1,250mhz surpasses Titan x maxwell. Though I'm PCIe 2.0 limited like no other, haha. Pascal puts the 390x to shame though most likely hahahaha. I bet if the Maxwell Titan X was clocked at 1333Mhz locked down static it would also put the delimited 390x to shame haha.

Mod with hex editor, fix checksum saving with Polaris Bios Editor and then flash.

Hi again, I tried lastly to put the 1875 Strap for the 2000Mhz mode.

Specifically I changed:

40 0D 03 02 99 90 00 00 00 00 00 00 22 AA 1C 00 F7 F6 7E 4F D0 55 13 19 C6 50 B7 0D 00 6C 06 01 1D 0C 14 20 EA 89 80 AC 03 00 00 00 1E 18 32 38 DB 36 47 19

with

40 0D 03 02 99 90 00 00 00 00 00 00 22 AA 1C 00 D6 72 7E 4B C0 55 12 18 C3 0F E7 0C 00 6B 06 01 15 0A 14 20 EA 89 C0 AB 03 00 00 00 1D 17 2F 35 CE 34 44 18


Saved bios with polaris bios editor, and again got a blue screen in windows.

For elpida card I had no blue screen issues, but with the micron card I simply can't get it to boot after driver is installed frown.gif

Strange...try this. 1875-2000mhz mix

40 0D 03 02 99 90 00 00 00 00 00 00 22 AA 1C 00 D6 72 7E 4B C0 55 12 18 C3 0F E7 0C 00 6B 06 01 15 0A 14 20 EA 89 C0 AB 03 00 00 00 1E 18 32 38 DB 36 47 19

or try change only one timing to see what happens

40 0D 03 02 99 90 00 00 00 00 00 00 22 AA 1C 00 F7 F6 7E 4F D0 55 13 19 C6 50 B7 0D 00 6C 06 01 1D 0C 14 20 EA 89 80 AC 03 00 00 00 1E 18 32 38 DB 36 47 18

Hi, newbie here

I have an annoingly not mentioned anywhere Gigabyte G1 Gaming RX 480 8GB
Anyone has any experience with it?

Here you can download it's stock BIOS

I have huge problems with it. EVERY try going above 2125MHz memory end with single color screen and hard reset... What can be done with it?
I'm not even able to read the vendor of memory...

Ok Excellent will try first only timing and post back.

Tried to change only the timing but after driver activation to bypass the signature check blue screen again on reboot. I am guessing the Polaris Bios Editor is not signing this new strange bios correctly
