Re: (WTB) Low Power ROM for Asus Non Reference 480 4GB

Hello All,

I have a couple of Asus non reference RX 480 4GB. I would be happy to throw someone some BTC so I can fit these on a 1000w.

I can provide original ROM.

Thanks in advance!

I'll give it a shot if you'll have me, How many cards? And what PSU Model do you need it to work with.

Also, can you upload stock ROM?

Awesome! I only have 3. The rig is 3 of these cards and 3 of the MSI rx 470 4gb. There are numerous Roms for that model that work so there is no issue there. The PSU is a Corsair HX1000i Platinum 1000w.

Hey man, I just started working on the ROM, but I noticed that the clock on the memory is low (1750 Mhz) and the Max Power Limit is set to (99 Watts) Are you sure this is the stock ROM?

99% sure. It's also here if you wanna use that.

Hmm, well that means you don't need a modded ROM, this default ROM is already 99 Watts, so should be able to have even 6 of these cards on a 1000 Watt PSU.

The only benefit I see for making a custom ROM is trying to get the VRAM higher default clocks and Lower the CORE Voltages and clocks to be more effecient.

That's weird. I most certainly cannot fit 6 of these on a 1000w. My kill-a-watt puts it over 1000. I guess try to crank down the core and I'll test it.

Here are the ROMS:

https://drive.google.com/open?id=0B6VgxfTqxux4cWFWbUpDelhQWFk

I made 2 core variants and 2 memory variants

Try the Stock Mem and Core 1125 mV 850 first, that should be the lowest Wattage ROM that would be named "Asus.RX480.4096.160817_core_1125_mv_850_memory_stock_timing_stock.rom"

If it's stable for more than 2 hours, I would then try the "Asus.RX480.4096.160817_core_1125_mv_850_memory_1900_timing_1650.rom" Which is the ROM with same low power core clocks + 1900 Mhz Mem Clock and 1650 Mhz Straps for better Dagger and Equihash performance.

BTW, do you have multiple GPUs? Incase the ROMS fail on boot, you can reflash the GPU with stock ROM if you have another GPU that you can boot with. (I'm assuming you know how to do with with ATIFlash/ATIWinFlash?)

Awesome! Will test tonight and report back! Yes I have bricked cards, and re-flashed using another GPU before. I use ATIflash cmd line tool.

Ok, cool

Let me know if the ROM Works or if the voltages need to be a bit higher

Which of those are supposed to be undervolted? While I see several modifications in PowerPlay, none indicate 1125mV (at least in the voltage table referenced by the DPM states), and there's no offset in the regulator initialization section in VoltageObjectInfo (nor is there space for one, you'd have to make room.)

You're right, these are basic PBE changes to both clock and voltages to the default curve, i did not do much else as I don't have access to the actual card to do much (safely)

@lamaonade80, which ROM worked for you? Did any of the memory OCed to 1900 with 1650 straps work?

Also let me know if it's stable after a day or 2 of running.
