The RX Vega 64 Owners Thread

Does anyone know why even at 45-50c all of a sudden my Vega64 Liquid fan will ramp right up to 2200rpm when like 1500rpm is all that is necessary. It's undervolted to 1125 P7 at 1712mhz so doesn't go over 280w. It's annoying because I'll pause the game and it'll be screaming, check the overlay and it's at 45c using 220w

Sometimes the onboard sensors will "spike" and the cards auto fan control will think its overheating. It ramps up for a split second then slowly winds down. The theory is that the human mind won't recognize or be bothered as much by a "slow changing" noise.

Mine does it too but I rid myself of the problem by locking the fanspeed to manual(but dynamic) between 1000-1400 and it never goes above or below those numbers.

Agree I've noticed this. I will relay this feedback to the driver engineering team and see if we can tune this behaviour further.

The I2C access to VRM is still an issue. By default HWiNFO will not access VRM via i2c, but it can be forced. The driver does support giving VRM temp info without i2c access, I believe AMD ADL is used, Martin would be able to state. In linked image left image is non i2c and right with i2c.

Using non I2C access the VRM temp info will sometimes be there other times not, I could be doing monitoring for 24hrs+ continuously and it will not appear, here is a 37hr run.

Using I2C access can mean GPU get's disconnected from rig (ie blackscreen, no GPUtach LED, reboot needed, etc). This occurrence correlates with just accessing VRM info via I2C (ie when you just open HWINFO). I can go few days without issue occurring or have it repeatedly in succession within minutes.

It does not matter if card is stock or OC'd, what VBIOS I use, etc.

I2C access = possible GPU disconnect from system, non i2c = hit'n'miss if I will see VRM temp info but never will GPU disconnect in testing so far.

AMD keep stating to Martin it is fixed but it is not. Please can this be highlighted and resolved, thanks

We're looking at it, I'm part of the internal discussion.

Thanks

, appreciate it.

Even on v18.1.1 Alpha this issue occurs. For a few days of uptime doing various things it was all good, then BAM! GPU disconnect :/ .

Ok, My time with Vega might be short lived.

I got a great offer for mine from a crypto-currency miner. It would give me nearly enough to buy a 1080Ti.

I love the Vega card, and it looks amazing in the case, but, I think I would be foolish to pass this chance up. Even though I think Vega has a lot more to give. But, the pure performance that the 1080Ti will give me now, is hard to pass up.

I seen your for sale ad and all the stupid comments posted on it. I was gonna list mine in the same place but with my EKWB block. Trust me what you got for it if you like. I'm also gonna look out for a 1080ti

When the deal is done, I will trust what I got for it. Well to be fair some of the comments were partly due to my mistype with the price. But, one guy did seem pretty clueless about Vega. But, you know what that site is like, always people who out to spoil ads.

LoadsaMoney · 15 Jan 2018 at 12:53

You should be able to sell it for way more than the cost of a Ti, going by how much they are new now, ridiculous.

Where did you do this?
I'm getting sick of mine, it causes me no end of problems since day 1.
The only thing it does perfectly and amazingly is mine cryptocurrency, but all I really want to do with it is play games (which is when it causes me much anger and frustration)

Well, You have been trying to push the card to the limits. If you just want to game, put the stock BIOS on. Run DDU in safe mode and remove current drivers. Reboot and then reinstall the 17.11.1
drivers. Do not install the Adrenalin drivers.

When the computer reboots go into custom settings but don't go too aggressive. Especially with the HBM overclocking. It causes so many crashes. Try to stick to middle of the road settings.

I had no trouble gaming. I only started having problems when I went with the Adrenalin drivers.

I listed my card on a local adverts site. I sold it today and have already ordered a 1080Ti, just playing the waiting game now!!

How do you know if i pushed the card to the limits? are you the guy climbing onto my balcony at night?? peering through my window?

LOL what? You have been all over this thread talking about what you have been doing with your card. Looking for BIOS mod to give you 200% powerlimit. You have flashed your 56 with 64 LC BIOS. I think you had the 64 AIR BIOS installed as well. Not too long you mentioned the speeds you were running your card at and said you wouldn't recommend them.

And now you say the Card is giving you lots of problems in games. Are you really surprised? You can do benchmarks and get great scores etc. But gaming is much more sensitive to overclocks. What might work with benchmarking can give nothing but grief when gaming.

And the first step in troubleshooting problems with games is revert everything to stock.

I always run stock for games as the small increase that can be had from overclocking is not worth it for any possible problems. Games have enough bugs that cause crashes without overclocking adding to them.

Some serious truth in this.

It's taken me a lot of time and effort to get a CPU, memory and GPU core/memory overclocked but at suitable/lower voltages. Testing each component in a variety of stressful workloads drawing maximum wattage took me well over a week before i found the maximum stable frequency at the lowest possible voltage.

A lot of effort for not much reward. In hindsight i may as well have just run everything at stock and would have completed several games in that time, Lol.

Wow I really didn't think anyone paid attention to my posts, you reciting back to me the past shocked me then.

Yes I have fiddled with all the bios's and clocks and hbm and benchmarking. BUT as I stated I have been having problems since day 1.

I will ignore your scathing review of my practices to explain a bit more.

AMDMatt said:

Well... as we all know, if the card decides there is thermal and power headroom it overclocks (boosts) itself.
In my case I'm watercooled so it does decide to boost, but when it does (and this is even on the stock bios) it goes too far and causes a sound loop crash to desktop.
at this point i look at the tach leds on the card which then light up 1 by 1 (1,2,3,4,5,6,7) until they are all lit.

At this point i will go into wattmatt and as soon as the mouse hovers over the reset option or tries to scroll to the timeline so i can see what happened then wattmatt crashes and says its become unresposive and needs to close.
So i wait for it to restart (or restart it)

I press reset, (the tach leds are still on full) and then as soon as the gpu is used for anything at all , the whole system hangs completely and i have to hard reset.

If anyone knows anything about this please let me know.

LtMatt · 16 Jan 2018 at 14:32

Your GPU sounds like it is faulty, it should not crash at stock settings. The tach leds thing is i a bug i believe and that happens after a crash, i can repro it by running unstable clocks.

You may have difficulty getting a replacement, so can you settle for lowering clock speed to avoid the crashing, or adding more voltage?

I'm wrapping my Vega's in cotton wool as they are becoming collectors items. I hope they live long and prosperious lives I've undervolted both by -0.050mv - 0.080mv.

The only way i can run it in games without these crashes seems to be , custom settings, -5% power limit , then it will work.... lowering the clock speed doesn't fix it, it will still overboost into 1700+ mhz and crash itself
I will have difficulty getting a replacement because no availability ? or because i have an eiswolf on it now, or changed the bios? or all these things lol
