AMD Radeon RX Vega 56/64 BIOS Mods & Results

[HeyItsChris]

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.

That is awesome, thanks for helping out those with Vega GPU's

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.

 

 

[HeyItsChris]

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.

[HeyItsChris]

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

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.

Now I have a new issue.  When I went back to stock sppt settings with those high limits on the temperature limits.  I simply had it undervolted a little from 1200mV to 1075mV & had the TDP up to 50% over 260W which yielded 288W & the hotspot hit 96C.  It doesn't run faster with higher than 84C though, I know this is a fact that 84C is peak optimal temperature limit that should be used.  So now my card won't post.  It was fine after running it for 2min at 90-96C on the hotspot, the core & everything else was less than 48C, its that insane hotspot that might have killed the card with too much TDP, as the max I found is 250W 250A 84C is optimal.  Now I guess I'll have to bake it again.  What a bummer.  Now I'm using my Google TV 43" 4K with Microsoft Edge browser latest Arm v7a version and its working fine.  If Only I could fix my Vega.  Any ideas?

[kithylin]

I know this is an older topic today and I hope the moderators will understand my responding to it as there is basically no other information on the internet about this. So my message goes to HeyItsChris (if you're still here): I own a Sapphire Nitro Vega64. Do you have a way for me to either flash a custom bios into it or a registry tweak or something to basically remove or eliminate it's power limit so I can actually overclock it some? 

[HeyItsChris]

@kithylinsend bios attach here as .zip & i'll take a look.  I'll increase the slider bar so you can go to 100% power limit & you can find your new limits & i'll set safer temperature limits, so you don't burn out the silicon diode under load.  It'll be sppt, because as far as I know, no bios mods, thus far for vega.

I've attached the bios. I've tried other things in the past. I browsed all the Vega64 bios's on the TechPowerup GPU Bios database and found one that supposedly has +30 watts more than my card's 300W power limit in it's bios. But every time I tried to cross-flash it into my card the AMD Flash Tool kept coming up with "Vendor ID Mismatch" and denied me. I spent an entire 2 days one time scouring through google and even using ChatGPT to try and find some command-line option to force the bios in and nothing I could do worked. I had even tried 24 different versions of the AMD Flash tool and none of em worked. I tried booting to a DOS bootable USB stick and doing a DOS flash without the OS running and that failed too. I thought we were supposed to be able to cross-flash Vega64... ???? I don't know.

 

I attached my bios extracted from this card with GPU-Z and I hope you can help me. If you could just modify the bios to raise the power limit to say 400W or 450W that would be fantastic. And maybe please point me to the exact download for the AMD Flash tool version that would let me flash your modified bios onto the card?

 

Any help would be appreciated. I pretty much gave up on ever overclocking this card until I found this thread at random last night.

@kithylinWhich card do you have, exact model?  I'll advise here shortly, in the next hour on SPPT option.  May you please send me the maximum rpm the card will turn at 100%, please?

It's this card: 

NITRO+ RX VEGA64 8G HBM2

WWW.SAPPHIRETECH.COM

NITRO+ RADEON RX VEGA 64 8GB

 

 

I actually had to swap the Vega64 out of the computer in the other room because it's not supported by Kohya AI training software so I had to use a GTX 1080 instead. I'll work on getting another spare computer set up and put the Vega64 in it to get it running so I can check software and flash it and stuff. It might be tomorrow or the day after for that though, so I don't know the maximum RPM right this second. 

 

EDIT: This card uses 3 x 8-pin PEG Power connectors so it should be no problem with a higher power limit bios. Sapphire limited it to 300W though despite this.

How many rpm does it turn @ 100% fan, go to amd radeon settings & crank to 100% & send me the rpm value.

[HeyItsChris]

@kithylinThis is a blind mod, because I didn't know the max achievable rpm.  Let me know what you think.  Post a video telling all about it, if you would, on YouTube?

~Be mindful of the long filename~

Simply save in safe location, double click, restart, good to go.  Let me know all about it.  Check AMD Radeon settings for changes.

@kithylinIt'll work fine, it just won't yield peak performance until I know what the fans can do at full tilt, understand?  Thank you.  Enjoy.

I understand and thank you but it'll be a few days now until I can get the vega64 back into a computer and try this and get the fan RPM for you. I'll get back to you when I can.

I thought things would take longer but surprisingly things finished faster and some people just canceled on me, work done.. so anywhere here's your requested RPM view for this Vega64. Now I can have a little time to play around with this card, it's just a side project to see what it can do.

[HeyItsChris]

@kithylinThe SPPT I sent is already dialed in.  Have fun, let me know what u find.
