The RX Vega 56 Owners Thread

Yadda said:
Are you sure the gains from higher HBM clocks are that small "across the board"? I've read that Vega really likes the extra memory bandwidth and I've seen people get significant performance gains in some games.

(Edit: the PSU is now fine, btw. The problem was coil whine and I sorted it by connecting to a different mains socket on a different power strip.)

Yeah it depends on the game almost certainly. Some will benefit more from the bandwidth than others.

Theres an interesting article by gamers nexus about why AMD used hbm2 for vega which was because of the need for bandwidth and low power to balance the high power of the gpu. I guess at some point a higher bandwidth has reducing benefit because the gpu is topping out. 56 will have a lower threshold than 64 due to the 8 fewer CUs. Only way to find out is trial and error. Just dont brick that nice new card of yours :p

Thanks, I always try not to. :)
 
Owned my V56 since release and have run it with a V64 bios since the second week of owning my card. With the V56 bios I couldn't get the HBM stable over 935mhz. With the V64 bios it runs happily at 1100mhz. I haven't noticed any issues with newer drivers as some users seem to report, currently using the latest Adrenalin 20.2.2 drivers.
Don't really have time to test more games but here is Rise of the Tomb Raider at 1440p, DX12, mostly max settings, motion blur and other annoying settings off.

Core 1630mhz, HBM 935mhz
Mountain Peak: 111.36 fps (min 67.04, max: 168.53)
Syria: 74.19 fps (min 43.89, max: 99.08)
Geothermal Valley: 73.94 fps (min:59.23, max:90.99)
Overall score: 87.21 fps

Core 1630mhz, HBM 1100mhz
Mountain Peak: 116.41 fps (min 67.78, max: 183.07)
Syria: 76.87 fps (min 60.14, max: 96.25)
Geothermal Valley: 76.39 fps (min:62.43, max:96.08)
Overall score: 90.63 fps

Other games may give more or less of a performance increase, at the end of the day I figured it was a free performance increase and you can't really brick your card thanks to the bios switch :)
 
Yeah mine is a Sapphire teference card, just used Sapphire V64 bios. I didn't notice any temp increases tbh but I do have a full cover water block on it. HBM probably is hotter than before but it only just goes over 50°c

Fair enough, cheers.

My Pulse seems to top-out at 64C when really pushed hard so I hope I have enough headroom left. There's one way to find out, of course but I think I'll sleep on it for a while before deciding.

I can see why you'd want to flash the bios with such a modest hbm2 oc. That's nearly 18% more vram mhz and a 4% game fps boost from that flash. I would probably have done the flash myself if I hadn't been lucky enough to get my hbm2 to 980 and if the pulse had a 64 equivalent. The Nitro+ or XFX nano bioses are possible options but not guaranteed I dont think. My warranty runs out in May so I might consider looking into it again then
 
I stopped fiddling with it for a while and had my first session on Division 2, which I picked up on the last day of the sale last weekend.

Wow! With the detail level turned up (to 75-80 iirc) and supersampling enabled in the driver settings it looks better than anything I've seen before, and it held 60fps solidly too. It would have brought my old 780 to its knees. Seeing VRAM usage at 7.1GB is going to take some getting used to!

I'm absolutely chuffed to bits and couldn't be happier with the card. :)
 
Glad your happy buddy. Its a great card, will do perfectly until big navi hits and we can see what the next offering for the £300 mark settles. I just need something that can push 4k now, my display is freesync but the 5700 Im bypassing as it doesnt quite have the grunt and the newer horizon stuff looks like having way better power efficiency.
 
Yes, that makes sense if you're pushing for 4k.

Some of us luddites are just now starting to look at moving up to 1440p so the little Vega should last me a while yet.

I moved to a 34" 1440p Ultrawide and would recomend it over a 27" 1440p because when the latter really doesn't offer much over 1080p 24 imo. I got a electriQ 35" WQHD, which is a fraction of the price of similarly speced monitors

The Vega handles this resolution pretty well too. I do tinker with the most unnecessary settings to get better FPS though

I too was stepping up to 1440 as the vega can handle it. The display was surprise gift from the wife courtesy of her checking out my rainforest list at a price I didnt spot (didnt buy from there). Now it means the door is open to 4k for future but I can drop down to 1440 for the current games until the next market clears. The vega is a top card, its going to be over two years old by the time we see the new stuff and out of warranty so I dont mind selling on to offset the cost.

That's good to know, thanks Andrew. I like racing (driving) sims and I've considered upgrading to an ultrawide monitor in the past (albeit a 1080p ultrawide). A 1440p ultrawide would be very nice indeed!

I like the sound of your wife, Th0nt. You're a very lucky man! I've heard that Vega 56 is/was touted as a midrange 1440p card (which is what initially drew me to it) so with a bit of fettling I'm guessing it could be upper-midrange, at a push. :) It seems to have enough horses for the job, anyway.

4k sounds fantastic but that's a few years off for me. "Riding the trough of the wave". :D

It was a unicorn thing tbh mate, generally computer parts and hobby purchases have to be snuck under the radar but Im not grumbling! On the no so positive side as you mentioned, 4k with good settings requires a meaty card so the next one will be a keeper for a long block of time once its done as I aint interested in 8k etc.

I will add the cavet that it ofcourse depends on your framerate targets. I tend to play RPGs and 60fps is acceptable to me. The only one constantly under that are the AC Odyssey/Origins and they did a poor job on that engine anyway.
 
Hello, I am new here and I need some help. I own a Sapphire Vega 56 Pulse, and for some reason its performance is very poor. In games it stays idle (20-30% usage) while I don' t even get stable 60 fps. Moreover it fails the sphere test in UserBenchmark. I tried to clean install drivers multiple times (latest and older versions) but I had no luck. I tried contacting AMD support too, but they don't seem really helpful. My PC specs are the following:
  • CPU : Intel core i7 8700k
  • Motherboard: Asus Rog Strix Z390f
  • Ram: G.skill 16GB 3200mhz (dual channel)
  • GPU: Vega 56 Pulse
  • PSU: Corsair RM850X
  • SSD: Samsung 970 Pro 512GB NVMe
  • My monitor is nothing special, just a 1080p Philips monitor
Any help is appreciated.
