The RX Vega 56 Owners Thread

GL, I had thought about it. Use Thermal Grizzly Kryonaut and minus pads.

I'm not sure what size pads I need, but I have some Kryonaut, a 2mm minus 8 pad, and some 1.5mm and 1mm Gelid pads left over from a previous project where I didn't know what thickness I needed either.

I've done a 390X before and I'm not expecting this to be any more difficult... Seems the bit where it can go wrong is ensuring good enough coverage on both the HBM and GPU dies. We'll see how it goes :)
 
Done. 2mm was about right for everything GPU side (1.5mm would probably be fine too). It has thermal pads on the backplate stock, these seemed a bit thinner, I used 1.5mm here.

Time to see if its made a difference.
 
Core, HBM, VRM temps have all dropped a reasonable amount. Hot spot temperature hasn't and that seems to be the limiting factor. I'm seeing pretty much the same boost clocks / power consumption as before which suggests the card is limiting because the hot spot temp is still 100C+.

Will try repasting and a different approach to mounting pressure and see how we go, but not today.
 
After letting it run for a while, it seems to have improved further. its now boosting higher than before with better temps. Need to monitor hot spot again but suspect thats dropped too now.

Time / heat required for TIM to settle in?
 
Think I'll give up trying to use ReLive Instant Replay with my Vega 56, even once you get past the issue where it won't start with a certain number of sound channels I get regular black screen crashes when using the feature. Doesn't happen when I use the Windows game bar for replay recording but that has it's own problems.

Tempted to undervolt and overclock my Pulse Vega 56 but not too sure if it is overly worth it?

It depends on the game, but it's quite easy to do. You just open Radeon Watman and follow the guides.

If you have a game playing in the background, look at the framerate before, and then look at the change as you play around with the undervolt, power limit, and clocks.

At the minute, I mainly play the Battlefield games, Doom and MW 2019/Warzone.
I'll do some before and after testing I guess and see if there is much benefit of the overclock. If not, An undervolt would probably be beneficial regardless. It done wonders to the temps of my 1070 laptop.
 
Does anyone have a air boost v64 bios flash for an air boost 56?

Ive got Samsung memory so was going to go for it.

Still need to get the fan under control too, it's pretty loud, do people use fan curves in wattman or afterburner? When I open afterburner my fan goes into overdrive which I assume is the curve set in afterburner.

Yea you want to undervolt especially want an undervolt as summer hits
 
As my card has a dual BIOS I thought I'd try a Vega 64 flash. After doing some research it seemed the best option for mine is an XFX (different manufacturer) Vega 64 as they're one of the only Vega 64 Nano PCB's, and the Vega 56 Pulse is nano. It worked, and there's certainly a performance increase there - I dialled in 1100MHz HBM and it seems perfectly stable. Not sure if I'll keep this though because for some reason this stops the Zero RPM fan feature from working.

May try a Sapphire Vega 64 Nitro BIOS, but I've read this may disable one of the display port outputs.

Which bios did you go for? I'm tempted to try my pulse too. I tried with some of the other Sapphire bios files but I got a subsystem id mismatch error.

XFX Double Edition. You will get a mismatch error with any BIOS, you have to use the command line tool and force the flash. I would recommend doing this on the power save BIOS so you can always switch back to the stock performance BIOS. If the flash fails and it cannot be recovered, do not then attempt to flash the remaining stock BIOS.

Yesterday switched back to the stock V56 BIOS. While there was a noteable performance uplift, there were a few issues which I couldn't get to the bottom of, for example broken hardware acceleration in Chrome, and instability in longer game sessions of continued high load despite all temperatures being well within limits. I tried going to stock clocks etc, but it was still not quite right.

I've not tried the Nitro BIOS yet.

Would you advise against it then? I'm running my hbm at 940 and core at 1662 at the moment
Click to expand...

Try it on the power save BIOS (switch towards outputs of the card I think? Double check that). In theory you should be able to flash it back after, but if you can't you've still got your primary performance BIOS available. As its a dual BIOS card with a physical switch the risk of a total brick is pretty low. My issues could be specific to my card.
 
Seems a little high for idle although it does depend on your case and room. Is that pre/post/during gaming?

Yesterday I changed the thermal paste on mine and currently idling between 33-36'C in a Phanteks Enthoo Pro M.
