Thanks!
Thanks for the guides guys used the lazy man guide haha and got my Vega 56 oc'd...
Core: 1702mhz - 1100mv
HBM: 955mhz - 950mv
Max temp 65, average maybe 62.
Got a timespy score at 7398, ran it a number of times with no crashing and did a lot of testing with tomb raider dagger of xian, so everything looks pretty stable.
Overall very pleased with the card works great for 1080p gaming silky smooth in everything I've got so far, and seems to have a decent OC on it.

Thats a massive core clock, what memory has it? Mine was Hynix.
It's probably samsung if he reached 955mhz stable. Also as per the lazy mans guide and many other sources that 950mv on the hbm is actually core voltage floor (minimum voltage for all performance states), hbm is hardlocked at 1250mv, that's why it's almost a must to overclock hbm to the maximum possible because the voltage is already there and it's a set number in V56 bios.
For core clocks I still don't get it, almost nobody ever gets the P7 value under load and it rather adjusts itself to a lower state. I have mine set at 1672mhz and getting 1600-1650, which is good. Others from what I've seen would get -100mhz or more under load from what they set in p7 and never reach it. It's supposed to be smart adjusting linearly between p6 and p7, if it likes the settings... also it can underclock if the voltage isn't enough and so on and so on. Seems like the user is a bit taken out of the equation. So 1702mhz could be stable... because the card is ignoring it for your sake, check hwinfo. That's just speculating, I never saw a definitive answer how the adjusting between p-states is done, it just is.

My Hynix reaches 950 MHz. It can do 960 MHz with artifacting, not tried 955 MHz.
Didn't know, saw many reports of hynix cards capping at sub 900, like 850-860. But maybe later batches got better.
Edit: siliconlottery... mine is Samsung capped at 940

Yeah my hynix is around 900 didnt push too hard as I heard it was inferior to other memory types.
Thought I'd test it a bit more this evening. 950MHz is as far as it'll go happily, 960MHz didn't artifact but Witcher 3 did crash randomly at this frequency. I've not touched voltages here or anything like that.
Core undervolt to 1080mV, and core frequency gets up to around 1680MHz when needed.
Yeah my HBM2 is Samsung memory, seems stable at 955/950mv no issues yet.
So I did some more playing around tonight and increased my P6 a bit.
As far as actual clock speed it's set in wattman to P6 1672/1040 P7 1702/1090 (1722 just instant crashes). According to the wattman overlay the average ingame is around 1670Mhz, if I look at HWMonitor it seems to think my core hits 1761 at times. HWinfo varies quite a lot from title to title in terms of average clock etc, but doesn't report an average higher than 1670MHz.
Max power draw is about 260w, average is right around maybe 235-245, temps on GPU haven't gone over 65C yet and HMB2 temp doesn't go above 70C.
So far tonight I've played anthem for a couple hours, had tomb raider running for 30/40mins, bit of Witcher 3 and run 3DMark timespy a few times and no crashing/artifacting so everything looks solid right now, see how it goes I guess haha.

Thats crazy low temps for a 56, mines at 1600 / 1050mv and hits 70-72c, 40% fan speed at max load after an hour or so, HBM temp hits like 80c.
are you sure thats under full load for an hour or so or just in the timespy run? as that wont run long enough to whack the temps up.
I keep my fan speeds fairly high, my x62 Kraken intake fans are set to 100% when I'm gaming and my GPU fan profile (based on core temp) is 50C 50%, 55C 60%, 65C 90%, 70C 100%. Essentially my fan profile is set to try and keep it at 65C max which gives me maximum core speed, once it starts getting higher it starts losing a little bit of core speed. I'll play again tomorrow night see what it does try n leave a game for a few hours. I had anthem running for a good hour or more, but anthem it seems draws less power and has lower temps than even witcher 3 while looking 100 times nicer lol I guess it's just well optimised.
The biggest difference is the intake fans on my rad with those at 100% everything stays super cool, it's ofc audible but when I'm gaming I have headphones on so I can't hear it anyway and on normal desktop usage I run on everything silent.
I want to get x2 140mm NZXT AER RGB fans for top exhuast right now I have x2 120mm on top, so hopefully it will get even cooler lol.
So ran it under 100% load for 1hr 30min and got this (timer only says 1 hour, I reset it by mistake the first time after around 30mins).

Yeah I mean while it is audible like I said it's really not that bad, I can't hear it at all with my headphones on.
Question about temps: does the 85C thermal throttling limit apply to the measured Hotspot temperature (and others) as reported in HWinfo or the gpu temp as seen on Wattman? There's usually a >15C difference between the two and I've always adjusted fan curve for keeping hotspot (and others) under 80C, and pretty much ignored the reading in Wattman (or GPU temp in HWinfo).
I'm not sure I think based on my testing it goes off the core temp, but again I'm not 100% sure either lol.

I have a FE vega 56 that I got as soon as it came out (at a great price thanks to AMD). Even though my case has dust filters the inside of the PC case is starting to get dusty and I am worried about my GPU with that cheap blower on top. Can I (and if so how) clean the dust out of a founders edition/reference card?
Soldato
What makes you think you cant get the dust out of it?
Soldato
Could be case like cm 690ii as my dust filters at the front of the case arent removable tho they can be ripped out if u try hard enough. I did as better without tbh.
