The RX Vega 64 Owners Thread

[Baz21226]

Was wondering if people could give me advice on the next steps of my overclock currently been working on state p6 and seem to have it nice and stable at the fan speed I can stand lol. I use Firestrike Extreme Stress Test to get my results and had a rating of 99.6% after 20 loops. Values below have what I have been getting by observing through Hwinfo64.

62c GPU Thermal Diode
68c GPU HBM Temperature
82c GPU Hot Spot
235w GPU Chip Power
Only reaches 2300 RPM on the fan
945mhz Memory

Gains a GPU score of 22050 on Firestrike

Also seem to have a problem that whatever my frequency is set to on the GPU i never hit it exactly on either Wattman or Hwinfo64 no matter if i have less or more voltage?

Anyone know of a software based way of turning off the PowerColor Red Devil LED? It's red and I am currently hating it, considering I was going for a white + black thing. Not sure if I can just easily snip out the LED by taking it apart.

There's a switch just above the logo to toggle it on/off .

Anyone experiencing hard crash where the screen just random go black? I mean at the moment the only game I play is just Monster Hunter World, and it can run for hours to ends no problem, but I get the occasion black screen hard crash (not the driver has stopped working and recovered) that require force restarting the PC.

Is it a case of the overclocking not stable because of not enough voltage, or could it be a driver issue?

Also I seem to be getting artefact if I overclocked the memory clock beyond 1000MHz, not sure if it is just I'm unlucky with the memory cannot handle higher clock, or should I up the voltage further?

I'd downclock the memory to 950MHz and see if the crash occurs then. It could be just an unstable stack of HBM for OC'ing.

Artefacts are normally the memory and you appear to be unlucky on what yours can do, i have had the black screen crash and normally its when i try to push the P7 clock rate higher than the voltage under it cannot perform at that setting.

Maybe useful to see what your settings are, but normally by dropping the P7 state even by a single step i.e 1637 down to 1632 could resolve the issue

I thought as much, as my pass experience of overclocking the memory on my 290x also prompted me to think I did not win the memory lottery. Regardless, I'm still happy with 1000MHz that it can do.

For the core clock at the I was:
State 6 1622Mhz 1000mV
State 7 1652MHz 1125mV

I will probably try increasing the voltage a little to see if it would help stabling the card.

Could it be your PSU?

I see someone is selling a Silverstone 650W on the MM as it wasn't powerful enough for their Vega 64.

Doubt it is PSU, as otherwise it should most definitely crash far more frequently during heavy load. At the moment it is just rare occasion that it crash, and also card's stock voltage is at 1200mV for state 7 (which people believe is higher than needed to be for the Vega64).

Mine would defo crash with a black screen on those P7 numbers and voltage, pump the P7 voltage to 1150, see how it goes.... or drop the P7 clock to 1647 and maybe drop the P6 to 1602?

Well this is less than ideal. Any ideas?

I just had a look at mine and memory is around the 25% mark as I sit at the desktop.

Interestingly the Relive host app was reading the gpu percentage at around 90% so I switched it off and then back on again and it shows gpu usage at 0%, but when I turned record on the gpu usage sit's up in the high 80's, Then when I stop recording the gpu usage stays up in the high 80's, I then tried turning Relive off and on again and it comes back with the gpu usage at 0%, Further testing shows that it's repeatable and it does it every time, the system memory usage doesn't go up like yours not even when recording and I thought it might of been related to having Instant replay on but I have it on set to the max of 20 minutes and it doesn't use the system memory up like yours is. They may be bugs so I'm going to report mine (report done).

Check what your recording settings are.

Intriguing, I just ran P7 only at 1744MHz @950mV and 1100MHz HBM2 (950mV there too). Ran fine and had ~1600MHz actual in Heaven extreme (same settings as the thread here). Got a respectable 2404 too.

Peaked around 200W on the GPU package which surprised me for a 1600MHz run.

 

[nashathedog]

not going to lie, apart from the first few days where I was obsessed with benchmarking. I spend most time on power saving mode and it drives my 3440 x 1440p monitor just nice

Same here, That's why I decided to buy a £450 (under £350 if you include what you save on the three games that come with it) V64 Red Devil instead of going for an overpriced RTX card, Plus I spent this weekend messing around setting up my case with some extra fans and an AIO for the cpu, I've been able to set mine up so the gpu core speed stays above 1600mhz with an under volt and the fans noise level is like night and day compared to how it was before. It's not as quiet as my 4790k and Fury Tri-x build was but it's close enough.

 

[nashathedog]

I have seen the settings beforehand but was asking if they ok to run from out of the box as I am not a expert in overclocking undervolting etc. You also say start with these how would I go about knowing if anything needs changing after I have inputted these settings?

Note that a lot of people putting settings up in this thread are running their vega as part of a water loop set up so be wary of just copying their settings. I'm running a Vega 64 Red Devil and these settings give me a decent balance of performance, temps and noise. I can go higher with the clocks but this is a good balance for running 3440x1440.

Spoiler

Well that makes sense the core settings hadn't taken properly only the mem, so it's a fubar run. More testing required methinks

yeah for me noise was more important than raw fps, especially as my max refresh rate is 75. So I lock my fps to 70 globally and tinker with in game settings as needed.

If a particular game needs more grunt to hit 60+fps, I'll make an exception

I haven't bothered locking the limit down, I have a 75hz ultrawide monitor so I tend to focus on the minimums staying above 60hz for the most part, that said Shadow of the Tomb Raider is under that a lot but it rarely drops under 50 and with the type of game it is that isn't a problem, To be honest I find I can always tweak an extra 10 or more frames from a games settings and more often than not it makes no real difference to how good the games visuals are.

Right after solving the Core not taking settings issue, I needed P7 set to 1752MHz @1050mV to get ~1610MHz consistently in Heaven. That was using 1100MHz on HBM2 and 950mV on the HBM setting. Wattage used was ~200 package load during the run. On Superposition it resulted in ~220W and ~1590MHz with the same settings. Heaven result was 2411 with min FPS at 38.4 and max at 200.2 Avg 95.7FPS. Superposition was in the ~4800 range (across a few runs) at 1080p Extreme settings.

OC done with OverdriveNTool and all testing done with all other power settings disabled so only active were P7 for core and P3 for Mem.

...herpa derpa. Might change the LED color tho, I get it's "The Red Devil" but mah color scheme!

 

[Skellz]

Picked up a Red Devil today and have been playing with the Wattman settings. Do the profiles not stay on every time you boot up?

Pretty new at this so far, but I have currently: 50% PL | P6 - 1582mhz/1075 | P7 - 1677mhz/1100 | Mem 1075mhz/1000 (frequency for core clock set at 3% results in ~1630mhz)

I have tried the Mem at 1100mhz/1040 but it crashes. Is it now worth me fiddling with the Mem and trying to squeeze more out and then focusing back on core settings or should I now focus on tweaking down the core settings at the current Mem settings?
