AMD Radeon RX Vega 56/64 BIOS Mods & Results


Recommended Posts

If anyone is interested I can help them flash the Powercolor Red Devil Vega 64 BIOS to their Vega 56 & Performance shall soar with my SPPT registry modifications.

 

So far I waxed the Vega 64's on Steel Nomad Light on 3dMark with my Powercolor Red Dragon Vega 56 on Red Devil Vega 64 BIOS with SPPT registry modifications & OverdriveNTool.

 

1710Mhz Core 1 Volt 

1190Mhz HBM2

Fans go full speed at 40C so the Hotspot falls below 79C at full tilt with a 250W power limit & 250A current limit.

I don't have any Vegas anynore, butI know a few guys here still have some  and might be interested.

 

I know I promised @Alastair some modded tables but I could not find my old ones.

 

Are yours modded with power AND current?

 

Those cards do love to be under water.

 

I had my 64 unlocked to something like 600W and amps. I would pull almost 500W at 1800MHz. I could never figure out how to add more voltage via software.

 

Be sure to submit to hwbot. I think I saw you joined the team.

Yes sir.  I can provide my SPPT tables registry files.  I have found max undervolt is 900mv at 1500mhz max & 1710mhz core is possible at 1 volt with up to 1190mhz HBM2.

 

This archive contains everything from the atiflash293 for flashing the BIOS from vega 56 to red devil vega 64 as I tested the liquid devil bios and it had issues so i stick with   the red devil vega 64 bios.  The command is in there too to flash the BIOS first then you can use the modded SPPT tables.

 

Good luck

 

Any questions, ask away.

 

Topaz Labs like intense tasks prefer the 1500mhz 900mv operation to keep it from throttling continuously under load for a long time at high power, it works so cool & fast at 1500mhz.  The difference is minimal, like from 48fps avg 1500mhz 1000mhz 900mv to 56fps avg 1710mhz 1190mhz 1000mv.  Only 8fps, which could be seen like its a lot but not really as I really cannot tell a difference between the two clock configurations under full tilt operation.

Would this BIOS be a good match for a Sapphire Pulse Vega 56?  My main concern is the memory clocks, this card never really liked overclocking it...

If it's Samsung HBM then MAYBE. More likely if it allows higher HBM voltage.

 

If it's the Hynix HBM like many of the Vega 56, then probably not. That Hynix HBM could barely get validated for stock clocks.

Makes sense, I had a Vega 64 reference card with Samsung HBM and the mem oc'ed fairly well but my Sapphire V56 never did.  Not complaining, I had picked up the Vega 56 brand new for fairly cheap not that long after launch for $299 and it served it's purpose in the living room well.

 

Talking about both of these Vega cards makes me miss my Radeon VII.  Card had such potential only to be crippled by a crappy stock cooler.  Ah well, considering I sold it for 4x the price I paid and it more than bought my 6900XT (during the gpu craze even with inflated pricing).

😊👌😁👍  Yes sir, the samsung HBM2 loves 1.356V on the vega 56 red dragon I have with the red devil bios.  Mind you, you can get 1190mhz out of the HBM2 on 1080p 3dmark, not 1440p or 4K as they becomes unstand.  Stable for 4K is 1675mhz core 1 volt & 1172mhz memory HBM2.  At 1172Mhz HBM2, that's 600 Gigabytes per second so it soars on memory intense tasks at nearly a 3/4 tera byte per second.  

 

Stock vega 56 is 1.25v HBM2 & red devil among all other vega 64 is 1.35v but reports 1.356V.

 

Here's a video show casing one of my registry SPPT files.  Ask which one to use because I threw my whole folder in that archive which may contain unstable SPPT for 4K idk I'd have to look again, i guess when im not feeling lazy i'll post a description for each SPPT reg file.

Well I'm finding out that 1500mhz is certainly not stable under a topaz labs video ai load from 1080p to 4k using Gaia Upscale HQ to H264 high profile yada yada yada.  

 

So I'm trying to dial it in & find out what clock is max achievable under a Topaz Labs Video Ai load because its by far the most load you can ever throw on a GPU, no doubt far beyond anything we've ever seen.  So much so, it pushes 900mv to nearly 250 watts, so it's a tight budget.

 

I'll do some more testing & tuning & post again later.

Testing 1333Mhz core at 900mv with 1000Mhz HBM2 look at these Topaz Labs Video Ai results.  Mind you there is a 84C limit across the board & 250W 250A limit.

 

Even at 0.900V at 1333Mhz we are still sucking down 235 WATTS & 249 AMPS rounded up.  It throttles the Hotspot at 84C to prevent damaging the SILICON, as this is my BABY GIRL.  Her name is Nicole, my Vega 56 Red Dragon.  lol

 

Gaia - Upscale HQ from 1080p to 4K is getting 1.8fps totally stable at 1333Mhz 900mV 1000Mhz HBM2.

Then I reduced the voltage down to the floor, 800mV @ 1133Mhz core 1000Mhz HBM2 totally stable big difference in power consumption & temps

Fresh Tune For Topaz Labs Video Ai Load.zip

I actually tested it again on my fan tuned, temperature & power limited SPPT Table Registry file & it gets 2.7 fps so I guess I'll be sticking it even know it was bouncing off the hotspot temperature limit & power limit, it still achieved about 1 extra fps over that over SPPT Table I thought was optimal.  Here ya go.

 

*update*
Maybe i was seeing things because i ran it again topaz labs video ai and was getting 1.7 fps, not 2.7 fps so yeah maybe i was seeing things.  So basically there is hardly any difference.  Except for higher gaming performance on the stock sppt tuned.

Here's one I made recently it achieves stability with Topaz Labs suites & also performs top notch in game.

 

1675Mhz core from 1630Mhz stock Red Devil Vega 64 BIOS (PS - It can achieve maximum 1710Mhz for benchmarks but may gimp the fps to 15 so leaving the Core at 1675Mhz and HBM2 at 1000Mhz is optimal).

1000Mhz HBM2 is the max allowable writable in the SPPT.  That's 512GB/s.  Otherwise on 1080p benchmarks, 1190Mhz is possible.  Usually peak stability in game is 1172Mhz ie 600GB/s.

 

Down from 1200mV to 1000mV.  -200mV reduction.  84C temp limits with 88C shutdown for safety at the maximum extent.

 

Fans go full speed at 40C, so the Hotspot remains throttle free below 84C.

 

250W 250A is optimal on the Powercolor Red Dragon Vega 56 Cooler using the Vega 64 Red Devil BIOS.  Just to let you know you must open OverdriveNTool and reset and apply to get the reduction in voltage or do it within Radeon Settings Tuning.

 

Good luck

 

PS - It will overheat & rape your card if left in the BIOS or anywhere outside of Windows, because the fans don't kick on properly outside of WIndows.

So if using the Red Devil Vega 64 Samsung HBM2 BIOS, rush into Windows & line up the reset and apply in OverdriveNTool to let the low voltage kick in.
